Purpose and scope of the guidelines
The purpose of the guidelines is to assist the boards, management and staff of
Social Housing Institutions in playing a more meaningful role in the compilation,
interpretation and application of financial viability studies during the property
development process.

Undertaking and preparing financial viability studies is a specialised activity that
requires in-depth knowledge and understanding of the property market, financial
market conditions, property development costs, indicators, technical aspects, and
managerial and operational practice. The person or team carrying out a viability
study must also have highly developed analytical and arithmetical skills, including
an ability to read statistics and the ability to do discounted cash flow calculations.

These guidelines could be used to get a better understanding of what a financial
viability study is, why the study should be done prior to developing property, what
should be included in a financial viability study, and which objectives the financial
viability should be measured against. The reader can refer to examples of feasibility
studies included in these guidelines. Examples of basic calculations have been
included in order to illustrate how one arrives at certain figures required to calculate
the overall financial viability of the project.

What often happens in practice is that professionals (e.g. project managers and/or
quantity surveyors) are appointed to do the viability studies, and they work on
their own without much meaningful input from the client organisation (the Social
Housing Institution). These guidelines have been prepared to help the Social Housing
Institution to better understand the principles and process, in order to provide
meaningful input, and more importantly – to be able to interpret and question the
studies presented by specialists critically and intelligently.

These guidelines only will not be sufficient to develop the reader into a financial
viability study practitioner or expert, and attempting to do financial viability studies
without the requisite experience and insight can be dangerous.

   n Note:        These guidelines and examples are specifically for “investment”
                  (rental) schemes. Although financial viabilities for selling schemes such
                  as instalment or direct sale have many aspects in common with those
                  for investment schemes (e.g. land and construction cost estimates),
                  the approach to estimating and assessing yields (profits rather than
                  returns) is very different, and a discussion thereof falls outside the
                  scope of this document. When conducting a financial viability study
                  for a selling scheme, you may also have to consider additional costs
                  such as sectional title costs and agents’ commissions.

iIntroduction to feasibility studies
                 Why should feasibility studies be done
                 before projects are executed?
                 Property development is sometimes defined as “taking the risk of sacrificing a
                 known present value (of one’s invested funds or equity) in return for an increased,
                 but uncertain, future value”.

                 To minimise the inherent uncertainty and risk, an investigation into the likelihood
                 of successfully executing a project should always be undertaken before actually
                 embarking on the project. This investigation is called a feasibility study. Feasibility
                 studies should be done very early in the life of a project, before detailed designs
                 and technical documentation are prepared, to ensure that time, energy and money
                 spent on detailed project preparations are not wasted on the wrong concept, and
                 to avoid irreversible commitments being made to unsuitable pieces of land.

                 Feasibility studies are essentially tools that are used to guide investment and
                 development decisions – the key “go”, “no go” (or “go back and revise”) decisions
                 taken at various stages in the life of the project.

                 What is a feasibility study?
                 Is it a feasibility or viability study?
                 Feasible means practicable, or capable of being accomplished, something that
                 can be done.

                 Viable means able to exist, or capable of developing and surviving without
                 outside help.

                 For our purposes, both terms refer to the desirability or otherwise of embarking
                 on a project and its sustainability after completion, and both can, therefore, be

                 The likelihood of a project being feasible is reinforced when the feasibility study
                 indicates that the objectives of the investor (in this case the Social Housing
                 Institution or SHI) should be satisfied if a specific concept or idea is executed on
                 a particular piece of land. Arriving at the right match between concept and land
                 is, of course, a process where alternative concepts are tried and refined using
                 a series of cost benefit comparisons (feasibility studies) until the best solution is
                 found. This stage of project preparation is called the pre-feasibility phase, and
                 corresponds with the project validation and development appraisal stages in the
                 Social Housing Institutions Operations Manual

What is measured and against which
Feasibility studies are not about uninformed speculation. The Social Housing Institution
as property developer should be very clear about its development objectives, so
that the feasibility of every project concept can be measured against these pre-set
objectives. Development objectives must align with the organisation’s mandate and
mission, and must be set to ensure its long-term sustainability through the execution
of successful projects. In a typical Social Housing Institution development, objectives
are usually divided into non-financial and financial objectives.

Non-financial objectives can be of a socio-economic and/or a political nature, such
as promoting urban renewal in a particular area, contributing to local economic
development and community empowerment, and so on.

We set financial objectives to ensure the project will pay its own way and contribute
to the long-term financial independence and sustainability of the Social Housing
Institution. Financial objectives usually include:
• Realising a surplus of project income over project expenses (return on investment),
   i.e. making a profit.
• Making sure project development costs don’t exceed the funding available
   (subsidy, loans, grants, equity if any).
• Ensuring project pay-back within a certain time frame.
• Making sure actual cash inflows are available at the right time to meet actual
   cash outflows (cash-flow projections).

Parts of an overall feasibility study
Financial feasibility studies, in order to be meaningful and not based purely on
speculative figures, need to be informed by the overall context and environment
within which the proposed development will take place. Feasibility studies are
therefore normally done in two parts.

The first part looks at the practical executability of a specific development proposal
on a specific site. This part of the overall study looks at the following aspects to
check their potential effect on project execution time frames, and on projected
income and expenses:

Socio-economic feasibility
This is a survey carried out to investigate demographic, socio-economic and urban
growth patterns and trends; and to see if the right target market and area for
development have been selected. In other words, is there a large enough population
with the “right” socio-economic profile to support the project?

Social Housing Institutions normally commission a specialist research company or
university to carry out this study (remember to include the costs in the financial
viability study – unless they are sponsored).

                    WARNING: Socio-economic surveys are sometimes nothing more than
                    a re-hash of outdated or unreliable census statistics that attempt to
                    create a vague kind of comfort that demand is somehow guaranteed
                    through the existence of a large enough population in a certain income
                    category. It is very important to obtain relevant, correct, current
                    information, and the socio-economic survey should be accompanied
                    by a marketing feasibility study.

                 Marketing feasibility
                 The target market is more specifically analysed to see if actual demand (need backed
                 by “purchasing power” or income) for the product exists, and if the objectives with
                 regard to rental and occupancy levels are realistic.

                 Legal feasibility
                 The site description, ownership details and legal status of the envisaged site are checked
                 for problems with the title deed and transfer of ownership, legal encumbrances such
                 as registered servitudes, long-term leases and other restrictions, and to ensure the
                 site has the necessary development rights. The purpose is to identify and quantify the
                 possible impact of legal issues on development time frames and costs.

                 Physical feasibility
                 The physical features of the site are checked to see if it can be built on, how much
                 the site cannot be built on, and what impact its features will have on development
                 costs. The aspects investigated include:
                 • Site topography and vegetation – slopes, rocky outcrops, marshes and wetlands,
                    water courses and flood lines, trees to be removed or conserved.
                 • Geotechnical features – sub-surface soil conditions and their impact on design
                    and costs of foundations, services and roads.
                 • Location and access – is it a favourable location with regard to economic opportunities,
                    facilities and transport, ease of access for pedestrians and cars, traffic issues, etc?.

                 The second part of the overall feasibility study is the financial feasibility or viability

                 Financial feasibility/viability
                 This part of the feasibility study uses the information supplied by the first part of the
                 study, as well as assumptions based on the experience and market knowledge of the
                 person or team doing the study, to test and fine-tune the concept (and alternatives
                 if necessary) until it provides an acceptable cost benefit solution that best meets the
                 project financial objectives. Final investment and development decisions are based
                 on the financial viability study, taking into account the other parts of the overall
                 feasibility study.

                 This guide concerns itself mainly with the financial aspect of project feasibility – the
                 Financial Viability Study.

                                                                           G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Project feasibility and institutional sustainability
When Social Housing Institutions engage in financial modelling for their business plans,
a common error is to combine project and institutional budgets and cash-flows into one
set of figures. What typically happens is that general management or overhead costs
are mixed with direct property management costs, and this presents a skewed picture
of project financials. Because the institution can seldom be carried by a single project
(unless it is very large, say 2,000-3,000 units), the temptation then arises to “massage”
the figures until they look good enough to sufficiently impress the funder(s).

The Social Housing Institutions business plan must, therefore, always reflect
1. Project feasibility for each project, together with a realistic time-frame. Projects
   must not be delayed for too long as their income contributions to SHI overheads
   are needed to help the company break even, and break the reliance on shortfall
   funding within a reasonable time – i.e. 3 to 4 years.
2. Institutional feasibility based on the project feasibilities. This should show
   clearly what contributions each project will make to the overheads of the SHI,
   on a realistic cash-flow basis, until the organisation breaks even and becomes
   self-sustaining. It should also clearly show what the overall operational shortfall
   will be on a cumulative basis for the pre-development and development stages,
   and how these shortfalls will be funded (bridging loans, grants, and donations in
   money and in kind e.g. staff secondments, etc.):

Financial viability studies
                 Parts of a financial viability study
                 A typical financial viability study consists of the following parts:
                 • An outer cover with the project name, who it is for, feasibility report number
                    and date (optional)
                 • An inside cover page containing project details
                 • A contents page
                 • An executive summary showing all the critical results and conclusions, including
                    a statement of the investor’s financial objectives
                 • Summary calculations of:
                    • Estimated total project cost, usually referred to as Total Development Cost
                      (TDC), or Total Capital Outlay (TCO)
                    • Estimated net project operational income (gross income less operational
                    • Estimated project returns (return on investment, internal rate of return or
                      IRR, break-even and pay-back periods)
                 • Detailed breakdown calculations of:
                    • Estimated current construction cost
                    • Estimated construction cost escalations
                    • Estimated interim cost of capital
                    • Estimated annual property operating costs
                    • Development and operational cash-flow projections
                 • A risk analysis
                 • Lists of assumptions and exclusions
                 • A brief project description, and the specifications the cost estimates are based
                 • A brief outline of the main outcomes of the socio-economic, marketing, legal
                    and physical feasibility studies that informed the assumptions (optional), or a
                    reference to the other studies used

                    Refer to worked example of a typical financial viability study for a
                    residential development project, page 36

                                                                   G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Steps in carrying out a financial viability study
Armed with the information gathered during an analysis of the socio-economic, mar-
keting, legal and physical feasibility studies, the person or team doing the financial
viability study should follow the procedure as set out below:
1. Set down the financial objectives of the project in consultation with the board
   and top management. This might entail decisions with regard to:
    • Required rate of return on investment
    • Required or desired operational break-even and capital pay-back periods
    • Project and per unit cost limitations

2. Use experience and apply contextual and market knowledge to determine all
   the main assumptions, for instance:
    • Projected building cost escalation rates
    • Projected loan interest rates
    • Projected rentals
    • Projected rental and operational expense inflation rates
    • Estimated time frames for the various phases of the project. (This is crucial
      as the time frame affects cost and income projections.)

3. Sit down with the professional team and agree on preliminary outline project
   specifications and important design details to be used in the cost estimates (remember
   that at this stage only very basic concept or sketch drawings are available to the
   estimator. Also, the outline specifications are at this stage just a rough guide to assist
   with construction cost estimating. The final detailed specifications will be developed
   much later, but must, of course, be in line broadly with these preliminary outlines).

4. Decide on the funding structure and conditions for the project (subsidy, equity and
   loans) in consultation with main stakeholders, the board and top management.

5. Do the calculations (estimated costs, income, returns and cash-flows).

6. Do a risk analysis. This is where the effect of possible changes in main
   assumptions on project viability is analysed by asking the “what if?” questions.
   Three broad scenarios are compared – optimistic, realistic (assumptions used in
   the study itself) and pessimistic.
7. Draw conclusions and make recommendations to the board and management.

At this stage, honesty is required to make realistic recommendations, and the board
must display the wisdom and courage to “walk away” from a project if the study
shows the project to be unviable, or if the risk analysis indicates unacceptably
detrimental effects if certain parameters are changed. This is often difficult when
the organisation’s heart is set on a particular project, and when a lot of hard work
and planning has already gone into project validation and preparation. It is better to
feel the pain at this stage though than to sit with an unviable project for many years.
Remember that not too many serious contractual and/or financial commitments have
been made at this stage, and it is still possible to pull out without too much fruitless
expenditure and effort. Later, when final plans have been drawn and a contractor
has been appointed and placed on site, it may be too late to stop the project.

cCompiling various parts of the
 financial viability study

                     Note: For visual examples of the parts described below, refer to the worked
                           example, page 36

                 Cover page with project details
                 The outer cover (optional) is kept simple. It contains the names of the client and
                 the project, the report number and the date.

                 The inside cover page (which can also be used as the actual cover) contains the
                 following information
                 • Client details (who the study is for)
                 • Project description (Project number or code, name, location, street name,
                      stand number)
                 •    Number and date of the study
                 •    Name of architect
                 •    Type and date of drawings on which building cost estimate is based
                 •    Method used to work out building cost estimate (square metrage, elemental
                      analysis, rough quantities, etc.)
                 • Name of person or team carrying out the study (not necessary if cover is on
                      the letterhead of a professional firm carrying out the study)

                 All pages of the report must be numbered, and should carry a header or footer
                 with the project name or code, and the date and number of the report.

                 Executive summary page of critical results
                 and conclusions
                 This page shows at a glance the following summarised information:
                 • Brief project description (number of different types of units)
                 • Estimated project time frame (main elements only: planning period,
                      construction period, operational life used for projections)
                 •    Project funding structure and conditions
                 •    Statement of financial objectives
                 •    Estimated escalated building cost and rate per square metre
                 •    Estimated total project cost and rate per square metre
                 •    Estimated gross income (and the rentals this figure is based on)
                 •    Estimated net income
                 •    Estimated returns and how they compare with the stated objectives
                 • Conclusions and recommendations

                                                               G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Statement of the investor’s financial objectives
(Usually included in the executive summary above)
The objectives are determined by the board and top management, and may include
the following:
• Project cost limitations (based on industry norms where possible):
   • Total project cost: e.g. R84 500 000 (It may be necessary to set this kind of
     limitation to align with limitations pertaining to the funding available).
   • Total costs per unit for different types of units: e.g. not more than R150 000
     (R3 000/m2) for a two-bedroom unit.

• Required rate of return: e.g. 12.5% p.a. In private sector developments for
   commercial gain, the required rate of return is usually determined by looking
   at the cost of capital, possible returns on alternative “safe” types of investment
   (money market, blue-chip shares, government bonds), and then adding a risk
   premium because property development is more risky. On the other hand, the
   investor also allows for the fact that good property will show capital appreciation
   or growth over time in addition to operational return. It is a complex decision.
   Social Housing Institutions may be guided more by what they consider to be
   a return that will cover the cost of capital and contribute sufficiently on a per
   project basis to long-term institutional viability. There are also sector norms and
   social housing policy guidelines to consider.

• Break-even period: This period indicates after how many years operational
   income should fully cover operational expenses. Ideally this should happen in
   the first year of operation, but this is rarely achieved in property development.
   It is more realistic to set a break-even target of 3 to 5 years.

• Pay-back period (optional): This period indicates after how many years the project
   will have paid for itself. A realistic target for social housing is 12-15 years.

Estimated total project cost
 Note: In the industry, the terms Total Development Cost (TDC) and Total
       Capital Outlay (TCO) are used interchangeably to denote the amount
       that represents the total capitalised investment in a development project,
       and which is used for determining rates of return on investment.

The TDC or TCO is the sum of all the “capitalised” costs incurred on the project (not
general overheads) from date of inception to the end of the development period (i.e.
the last day before commencement of the trading or operational phase. This usually
includes the costs associated with land and services installations, construction and
professional fees, but also some costs that would normally be viewed as operational
expenses during the trading phase, for example “interim” property tax and interest
on building loans during development.

                      In ordinary commercial and social housing developments, the main components
                     of Total Capital Outlay could be spread as follows:

                                                                  Approximate range: % of total project cost

                                                                   projects                  projects

                         Note 1: The ranges for some items can be quite wide. If you get land for free,
                                 land cost will be a very small proportion of the total, meaning that one
                                 or more of the other major components such as construction costs will
                                 automatically constitute a larger percentage of the total.

                         Note 2: The percentages in the table above are percentages of total development
                                 cost, and not of construction cost. Professional fees, for instance, may
                                 only be 6.5-9.5% of TCO, but that could translate to 8.67-12.67% of
                                 construction cost (if construction cost is 75% of TCO), or 7.65-11.18%
                                 (if construction cost is 85% of TCO). Since professional fees are more
                                 directly related to construction cost than to TCO, it is customary when
                                 discussing or estimating or negotiating fees, to speak of them as a
                                 percentage of construction cost.

                     In social housing projects currently, the land costs are usually close to zero, and cost
                     of capital is much lower because the injection of subsidies, grants, and “soft” equity
                     loans means that there is no, or little, loss of interest on equity.

                     Private commercial developments are normally funded through a combination of:
                     • Own capital or equity (20-40% of TCO)
                     • Loans for the balance required (60-80% of TCO)

                     There is no subsidy applicable, and the full project cost must be funded through
                     equity investment and borrowings.

                                                             G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

In social housing projects the funding is usually in the form of government subsidy,
grants, donations, debt funding from development finance institutions, and in some
instances limited equity from own reserves. The amount of subsidies and grants is
usually deducted from the TCO, and returns are calculated on the balance only.
This calculation indicates a favourably skewed picture when compared, for instance,
with returns in private developments, which are calculated on the full project cost,
for example:

Case 1 – returns based on full project cost without the deduction of subsidies:
Total Development Cost (TDC)                                     R 100 000 000
Net annual income (NAI)                                          R 10 000 000
Return on investment (ROI) = NAI/TDC = R 10 000 000/R 100 000 000 = 10.0%

Case 2 – returns based on balance project cost after deduction of subsidies:
Total Development Cost (TDC                                     R 100 000 000
Less: Subsidies                                                 R 30 000 000
Balance of investment (mainly loans)                            R 70 000 000
Net annual income (NAI)                                         R 10 000 000
Return on investment (ROI) = NAI/TDC = R10 000 000/R70 000 000 = 14.29%

In reality, the above effect is lessened (or even completely negated) by the fact that
the introduction of a subsidy caps the rental income below what could be charged
in the market, while development costs are not similarly capped, for instance:

Case 3 – returns based on balance project cost after deduction of subsidies
(but with rental income capped because of subsidy rules):
Total Development Cost (TDC)                                        R 100 000 000
Less: Subsidies                                                     R 30 000 000
Balance of investment (mainly loans)                                R 70 000 000
Net annual income (NAI) (capped by subsidy requirements)            R 6 000 000
Return on investment (ROI) = NAI/TDC = R6 000 000/R70 000 000 = 8.57%

Cost of surveys and studies
Socio-economic surveys:
Sometimes even before a particular project is identified and conceptualised, the
SHI will commission a specialist firm or university department to conduct a general
socio-economic survey of the target area. The cost of such surveys may be sponsored,
but if not, should be included as a project cost.

Environmental Impact Assessments (EIAs):
Once a project is identified it may be necessary to conduct an EIA in terms of
environmental protection legislation before permission can be granted to proceed
with development. The cost of this assessment may also be included under land
costs or professional fees.

                 EIAs are usually required where the development requires new township
                 establishment or a major rezoning of land use. Township establishment is the formal
                 town planning procedure where “raw” farmland is converted into registered or
                 proclaimed urban development land via a simultaneous rezoning and sub-division
                 (optional) of property.

                 Archaeological investigations/Heritage conservation reports
                 Sometimes sites have known or potential archaeological remains, or these may be
                 uncovered during building operations. An archaeologist would then be appointed
                 to carry out an investigation and make recommendations on the relocation, or
                 conservation of the remains where they were found, and the costs (and effect of
                 possible delays) of this would have to be incorporated into project cost estimates.
                 Fortunately, this rarely happens on urban sites.

                 Existing buildings on certain sites might be protected by heritage conservation
                 legislation, and although the architect would normally be aware of this, it may be
                 necessary to commission extra reports before alterations and/or demolitions can
                 be carried out. Sometimes the existing buildings, or at least certain parts of them
                 (such as the external façade), may have to be incorporated in the designs for infill
                 or new builds.

                 Land costs
                 The typical components are:
                 • Purchase price/market value
                 • Transfer cost or VAT
                 • Geotechnical investigations
                 • Legal costs related to Land Availability Agreement (if any)

                 Purchase price/market value
                 In private sector developments, the cost of land is included at current market value
                 rather than at historical cost (or purchase price). This is because the true cost of the
                 land is its realisable value that could be converted into cash by selling it rather than
                 “locking” that value into the total investment made in the project, or “sacrificing” the
                 immediate return in exchange for a longer-term return. The logic of this is evident
                 where a property may have been inherited or obtained, long ago, at a historic cost
                 that does not reflect current reality. Where land has recently been bought, or is to
                 be acquired in the near future, the purchase price is usually similar to market value
                 (unless the buyer paid too much or too little), and the problem falls away.

                 An argument could be made that SHIs should follow the same principle, even
                 where land is donated or acquired at nominal cost, but this is usually not done,
                 which means that financial viability studies for social housing projects are not
                 done on the same basis as those in commercial developments, and returns cannot,
                 therefore, be compared with or benchmarked against similar developments in
                 the private sector.

                                                              G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

However, SHIs have other costs that private developers may not have, such as
provision of social facilities, community development and tenant training. This may to
some extent negate the “undervaluation” of land costs in social housing projects.

Transfer cost/Value Added Tax (VAT)
By law all property transfers must be registered at the deeds office, and a tax is pay-
able to government in the form of transfer duties or Value Added Tax (VAT).
• Transfer duty is paid to government as a sliding scale percentage of the value of
   all property-transfer transactions between natural persons who are non-vendors.
   Non-vendor juristic persons (e.g. companies) pay a flat rate of 10% of the land
   value. In property transactions that are not considered arm’s length (e.g. between
   family members, or in the case of donations and special deals), the receiver will
   insist on an independent valuation of market value, and base the transfer duty
   on such valuation.
• Value Added Tax (VAT) is payable in place of transfer duty where property is
   purchased from a vendor (such as a property developer).
• Transfer registration fees are paid to the conveyancer (attorney) attending to
   the transfer (also on a sliding scale percentage based on the property value).
   These fees are payable regardless of whether transfer duty or VAT is paid to

The scales showing duties and fees payable, such as those in Moffat’s Improved Table
of Transfer and Bond Costs, are obtainable from any legal firm or legal publisher.

Geotechnical investigations
Problem soils (heaving clay, collapsible sands, dolomite) are common in South Africa,
and it is always prudent to carry out geotechnical investigations of a prospective
building site. They are done by specialists (some civil engineering firms also have
geotechnical divisions), and usually involve:
• Digging test pits over the site to expose the underlying strata for inspection
• Taking soil cores for analysis in a laboratory
• Preparing a report with diagrams showing the underground soil profile, and
   recommendations with regard to foundation types and bedding, and jointing
   of service pipes below ground

The cost of these investigations varies according to the size of the site and the
number of pits dug and core samples taken, and can be substantial on large or
problematic sites.

Legal costs related to Land Availability Agreement
If the Land Availability Agreement is with the local council, the municipality’s legal
department will draw up the agreement and there will be no cost to the SHI. Some
municipalities may, however, charge for this service (especially where the SHI is not
a municipal entity). The SHI may also wish to have the agreement checked by its
own lawyers, or may prefer to have it drawn up by them, and checked by council’s
legal people. Quotes or estimates of cost would then have to be included in project
cost estimates.

                 Town planning and related costs
                 A number of options exist with regard to the status of the land earmarked or acquired
                 for the development:
                 • Raw farmland on which township establishment must still be carried out

                 The following main costs must be allowed for:
                    • Application fees to the local authority
                    • Advertising costs
                    • Cost of plans and printing
                    • Town planner fees
                    • Land surveyor fees
                    • Bulk service contributions to council (can be substantial)
                    • Cost of legal agreements
                 • Proclaimed land, but on which some formal town planning or legal procedures
                    such as rezoning, consent-use application, relaxation of development controls,
                    sub-division or consolidation are required

                 Some or all of the following, as may be required (check beforehand):
                    • Application fees to the local authority
                    • Advertising costs
                    • Cost of plans and printing
                    • Town planner fees
                    • Land surveyor fees
                    • Bulk service contributions to council (can be substantial)
                 • Proclaimed land with the necessary development rights and on which no further
                    procedures are required

                 No further costs except that the boundary beacons may have disappeared, and a
                 land surveyor will have to be paid to re-establish them.

                 Land servicing costs
                 Where proclaimed serviced land with the appropriate development rights (zoning)
                 is acquired, there are usually no further costs in this regard

                 Where land is rezoned, sub-divided or consolidated, there may be some costs
                 involved in establishing separate service connections, or upgrading existing
                 connections, and in the form of bulk service contributions to the municipality.

                 Where township establishment is required, there are substantial construction
                 costs and professional fees involved in designing and installing so-called internal
                 township reticulation services (such as roads, stormwater drains, water, electricity
                 and streetlights, and sewerage installations). These costs can range between R25
                 000 and R60 000 per erf for individual single dwelling erven, and between R8 000
                 and R20 000 per dwelling unit (unit, townhouse or row house) on medium-density
                 multi-unit complexes. On a site where 300 units in walk-ups are being developed,
                 services could cost between R2.4m and R6m (based on prices in 2006).

                                                             G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Municipalities are responsible for providing bulk and link service infrastructure and
connections to the new township. They usually obtain funding for this from national
government via the Municipal Infrastructure Grant (MIG), the Department of Water
Affairs and Forestry, the Development Bank of South-Africa (DBSA), and where
applicable, a combination of grants and loans from district councils.

Interim rates and taxes
Interim rates and taxes are usually not payable in the event of a land availability
agreement with the council, as transfer only takes place at the end of the development
period. From the moment a property is registered in the Social Housing Institution’s
name, the Social Housing Institution is responsible for paying property tax to the
municipality. Land is sometimes also acquired early on in the project cycle, which
means that the Social Housing Institution is liable for these taxes, even during the
period of the actual development of the property.

Property tax paid up to the end of the development period is capitalised, i.e. added
up and included in TDC/TCO. According to new property rates legislation, rates
are levied as a percentage of the total market value of land and improvements per

   NB: Remember that the value of property increases after township
   establishment and rezoning, and that different amounts of tax,
   therefore, apply before and after these procedures, which must be
   factored into the cost estimates. In addition, property rates and/or
   valuations upon which they are based are increased annually. In a
   multi-year project, these increases must be taken into account in
   the cost estimates.

Some councils levy additional penalties on undeveloped land (applicable where the
land is acquired and then delays in the development process occur).

There may also be charges for grass cutting and keeping sites clean before and
during construction. Always check carefully with your local council which of the
above charges apply.

Escalated construction costs – top structures and site
The purpose of estimating construction costs on behalf of clients or employers is to
predict the most likely contract price that will be obtained from contractors in the
market at a given time in the future, and most importantly – what the final cost will
be at the time of completion.

S H F BP6 2006

                 At first, the construction cost is estimated as at the present time and under prevailing
                 construction market conditions (Estimated Current Construction Cost). It is possible,
                 however, to determine the estimated cost of a building at any time in the future by
                 making assumptions about the rate of escalation of construction costs due to inflation,
                 and the likely prevailing market conditions at that time, and then compounding the
                 estimated current cost by the necessary factors. Building cost estimates are usually
                 prepared for the employer by a professional quantity surveyor (QS or PQS) who must
                 have an up-to-date knowledge of building market conditions, trends and prices,
                 and of how contractors’ rates and prices are made up.

                 There are different ways of drawing up an estimate. Each method serves a particu-
                 lar purpose and requires different kinds of information. Where, for example, only
                 a rough indication is required, the “cost per unit” method of estimating could be
                 used. At the other end of the spectrum, a highly accurate estimate of cost can be
                 obtained by pricing out a detailed Bill of Quantities. The most reliable method is
                 the Elemental Building Cost Analysis, a method that is both quick and accurate.
                 Elemental estimates must cover the following main cost sections:
                 • Work carried out under separate contracts before the main contract starts (e.g.
                    bulk earthworks, piled foundations)
                 • Contract preliminaries
                 • Demolitions (if any)
                 • Alterations (if any)
                 • Primary elements (structure, shell and finishes)
                 • Internal service installations (plumbing and electrical)
                 • Special installations (including main contractor’s profit and attendance)
                 • External works and services
                 • Service connections
                 • Construction contingencies
                 • VAT

                 Some of the above are more troublesome than others, and additional guidelines
                 are given below:

                 Estimating the cost of demolitions
                 It can be difficult to estimate the costs involved in the demolition of existing buildings.
                 These are largely determined by the value of salvageable materials such as windows
                 and doors, roof timber, sheeting and tiles, sanitary and other fittings, wooden flooring
                 (in older buildings), etc. Unless the client specifically wants to retain these materials
                 for own use, the contractor may take them and allow a credit (reduction in price)
                 equivalent to their value. In some instances, the value of these items may exceed the
                 cost of breaking down and removing bulk materials such as concrete and brickwork.
                 In such cases, demolition tenders will contain two options – tenderers can insert a
                 cost, or more likely, an offer to “buy” the building from the client and pay for it.

                                                              G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Estimating the cost of alterations
Alterations can vary from simple refurbishment (cleaning, patching and painting)
to major structural and layout changes, as in the conversion of an office block into
residential flats. In the case of the former, it may be possible to develop inclusive
square metre rates for use in preliminary estimates from analysis of previous jobs, if
the work is similar. The only proper way to do the latter cost estimates is using more
detailed measurement (the guidelines in the Standard System of Measuring Building
Work published by the Association of South African Quantity Surveyors could be
followed here) and costing of such measured work required to be carried out.

A few points to remember:
• When solid components of a building are broken up, their volume for handling
   and carting away purposes increases substantially (by up to 50% or more).
• Most municipalities levy a dumping charge at their landfill sites for building
• Allow sufficient contingencies for what may be found once old structures and
   components are opened up or removed.
• Doing alterations is more difficult and risky than new work – contractors tend to
   apply higher mark-ups for alterations than for new work of the same value
• When an opening is cut in an existing wall, in most cases it is necessary to re-
   paint the whole wall, or even the whole room, rather than just patching and
   making good around the opening.

Estimating the cost of external works and services
As with special installations, external works and services are often incompletely
indicated on sketch plans, or not shown at all.

Pay special attention to stormwater disposal, landscaping (hard and soft) and planting,
garden furniture, etc.

Check with the local authority for an idea of their service connection fees. These
can be substantial. Where additional work is done at existing premises, it is often
necessary to allow for substantial and costly upgrades to services and connections.

Contingency allowances
This is one of the most misunderstood and abused aspects of estimating. Some
consultants (and their clients) see it as a simple case of “adding an extra 10% so we
have a bit of fat in the estimate”.

Instead, contingencies should be divided into two distinct categories of uncertainty
or risk, and each category should be considered rationally before deciding on an
allowance (past experience will help in this regard):

S H F BP6 2006

                 1. “Design and detail development” – to allow for lack of detail at sketch plan at
                    estimating stage. This allowance should be high in the preliminary stages, and
                    reduce with each subsequent estimate as more detail becomes available from
                    the design team. Once tenders are in and construction is ready to start, this
                    could be reduced to a very small allowance, unless parts of the design are still
                    incomplete. It is usual to allow 2.5% to 5.0% of estimated final building cost in
                    the early stages of the pre-feasibility phase when designs are still basic, reducing to
                    around 1.0% when detail design development and technical documentation are
                    complete, and 0-0.5% when tenders are in. (For refurbishment and conversion,
                    the initial contingency should be increased to 7.5-10.0%). This allowance is part
                    of the construction cost, and has nothing to do with the architect’s fees.

                 2. “Building contract contingencies” – to allow for real unforeseen expenditures.
                     The circumstances of the project will determine the amount that should be
                     allowed. It should also reduce up to a point, but an amount should remain in
                     place until construction is well underway, or even to the very end of construction.
                     How much to allow depends on the circumstances. It is usual to allow 2.5-5.0%
                     of final building cost in the preliminary estimates, reduced to around 1.0-2.0%
                     when tenders are in, and reduced even more from time to time in cost reports
                     during the construction phase. (For refurbishment and conversion, the initial
                     contingency should be increased to at least 7.5-10.0%.)

                 The total contingency allowance (sum of the above) could vary from 5.0%-10.0%
                 initially (15.0%-20.0% for refurbishments and conversions), to around 2.0%-3.0%
                 once tenders are in.

                 Cost escalations – why estimate of current construction cost only is
                 not good enough
                 The starting point for all construction cost estimates is the day on which the estimate
                 is done. In other words, the rates used are those that apply on that day, as if the
                 project could be completed on the same day. This is usually called the “ESTIMATED
                 CURRENT CONSTRUCTION COST”. This is logical because the rates known to us
                 at this stage are from current or (recently) past tenders, and not from the future.

                 However, to estimate only the current building cost is not realistic. Financial feasibility
                 studies (of which the estimate of construction cost is an important part) first have
                 to be carried out, tender documentation must be prepared, tenders called for and
                 adjudicated, plans submitted for scrutiny, and permission to start building granted
                 by the local authority, etc. This can take from 4 to12 months, or longer on large
                 and complex projects.

                 During this time, construction costs will fluctuate in response to both macro-
                 economic and local construction market factors. Recently, these fluctuations have
                 almost always been upwards as a result of continued inflation, and it is expected to
                 remain that way for the foreseeable future. (For a brief period In the 1980s, building
                 costs went down slightly.)

                                                              G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

The future tender price will always be higher than the estimated current construction
cost, which must therefore be escalated in full for the estimated total planning period
at a projected rate based on construction market trends.

 Note: Worked examples of how to estimate both pre-tender and post-contract
       building cost escalations are given in Annexure A.

The time factor
In order to be able to estimate preliminaries and escalation costs on a construction
project, one has to know how to estimate the length of the planning and construction

The project planning and construction periods (time) have an important effect on
time-related cost aspects such as:
• Preliminaries (especially salaries, plant and other time-related items)
• Pre- and post-tender construction cost escalations
• Financing cost (interim interest)

The effects of time on final building costs as outlined above must always be taken
into account in building cost estimates. This requires the highly specialised knowledge
and skill of a competent professional Quantity Surveyor.

Estimating project time frames
One of the first things the SHI management should do when a new project is initi-
ated is to draw up an overall time-frame or programme for the whole development
process. This is done in consultation with the board; key stakeholders such as council,
province and NHFC; and the project manager (if already appointed). It is a good
idea to divide this process up into the project phases, with critical milestones at the
end of each phase (and/or sub-phase) in the programme. This is a useful exercise
to help the parties:
• Get an indication of the workload ahead.
• Understand the many aspects of the process.
• Understand how activities interact with each other.
• Understand how the programme is affected by the workload, the duration of
   activities and the required lead-times.

A time-frame or programme is required to perform the project management function,
and to enable Social Housing Institutions to monitor the project, its progress and
performance. It is an important tool when doing cost estimates and financial
viability studies (in which land-holding costs, interim finance costs and building cost
escalations are all based on time frames). A realistic development time frame will
also enable the SHI to clearly quantify operational shortfalls during the development
period, and focus on finding ways to fund these.

 Note: More detailed guidelines on how to estimate project time frames are
       given in Annexure C.

                 Professional fees and disbursements
                 Professional fees
                 In preliminary estimates of construction projects, professional fees are generally
                 calculated as a percentage of final building costs, and are generally between 10%
                 and 20% of the final construction cost. The actual percentage depends on the size
                 and complexity of the project, the degree of repetition of standard unit designs, and
                 the level of professional services required by the client.

                 On projects with simple buildings, a lot of design repetition, and limited involvement
                 of the independent professionals in the post-contract administration and supervision,
                 such as low-cost housing schemes for government, professional fees may be as low
                 as 6% to 9% of the final building costs.

                 In modern office and shopping complex projects, with sophisticated electrical
                 and mechanical services, where the full range of professionals (project manager,
                 architect, consulting engineers, landscape and interior architects, etc.) are employed,
                 professional fees may range between 13% and 18%.

                 In labour-intensive community-based building or civil engineering projects where
                 training, mentoring and support services such as materials and construction
                 management are required in addition to normal design and supervision, professional
                 fees may be as high as 20% to 25%.

                 For social housing, professional fees are generally between 8.5% and 12.5% of final
                 building costs.

                 The correct way to estimate fees is to estimate the value of work in a project that each
                 consultant is responsible for, and then to estimate the fee for that consultant on the
                 basis of the recommended scale of fees and tariffs for that profession. For practical
                 purposes, some of the general principles behind fee-scales are as follows:
                 • They are based on percentages of construction cost (usually the final cost).
                 • These percentages work on a sliding scale – high percentages on small contracts,
                    or on the first parts of larger projects, and lower percentages on larger projects
                    or the remaining parts of these projects.
                 • Multipliers are applied for more complex or risky work.

                 The professionals usually employed on social housing projects include:
                 • Architects (who may also perform the urban design function)
                 • Structural/civil engineers
                 • Mechanical/electrical consultants
                 • Landscape architects (optional)
                 • Interior architects (optional)
                 • Quantity surveyors
                 • Town planners (if required)
                 • Land surveyors (if required)
                 • Project managers

SHIs should take care when structuring their professional teams to avoid duplication
of fees on the one hand, and gaps in responsibility on the other. This is especially
true of two key positions on project teams, namely the principal agent (PA) and
the project manager (PM). The PA is the leader of the professional design team and
takes prime responsibility for administering the building contract, assisted by the
various other professional consultants in terms of their appointments and briefs. The
PA does not necessarily provide overall project management. The project manager
is responsible for the overall management of the project or contract.

The conventional method is to appoint one of the members of the professional
team as the principal agent, with the employer (SHI) providing the overall project
management, which is the responsibility of the in-house development manager or
an external professional project manager. The position or function of principal agent
is to create the building contract, and as such speaks to “project management” only
of matters pertaining to the building contract itself. It does not include the many
additional project development functions such as managing stakeholder involvement,
co-ordinating and “chasing” parties involved in assembling and securing land, project
funding, etc. for which the employer (the SHI) must still take responsibility.

The roles and responsibilities of the PA and the PM must be clearly spelt out in the
different briefs and agreements. The customary way is for the PM to take on the
additional role of PA, or else have an overall PM, with the PA directly in charge of
building operations, and reporting to the PM on aspects pertaining to the building
contract. The PA would, for example, exercise cost control on the building contract,
with the PM assuming overall responsibility for cost control and reporting on all
aspects of the project. The PA’s building contract cost report would then be an input
into the PM’s overall project cost report. Special attention must be paid, however, to
the “grey” areas where responsibilities could be seen to overlap. This could lead to
important issues being neglected because the one party thinks the other is looking
after them. For instance, it should be made clear who is responsible for making
sure the boundary pegs of the property are in place prior to site handover, who
is responsible for chasing up service connections, and whose responsibility it is to
ensure that occupation and compliance certificates are obtained.

The principal agent can be any of the professionals on the team and there are two
streams of thought:
1. Architect as principal agent
   As the main design agent and leader of the design team, it makes sense to
   appoint the architect as principal agent because he or she has the best overall
   grasp of the required end product, and best understands what is expected from
   each member of the team.
2. QS as principal agent
   It makes sense to appoint the QS as principal agent because he or she controls
   the purse strings, has a better knowledge of contractual matters, and is generally
   better at routine paperwork and administration than the more “creatively-
   minded” architect.

S H F BP6 2006

                 Both instances work, and the SHI’s decision should be based on an assessment of
                 leadership qualities and experience of the people involved, rather than the profession
                 they represent.

                 Another option is to appoint the PM as the PA as well, and have all the professionals
                 report to him or her. In this case, the architect and engineers will be responsible
                 for design only, while the PM/PA will run the building contract and supervise the
                 contractor. The design consultants may be consulted by the PM/PA on technical
                 or contractual matters on an ad-hoc basis. The QS will perform his normal duties
                 under the direction and control of the PA.

                 There are different models regarding appointing the PM/PA question:

                 Model one (for small/simpler projects):
                 • The SHI assumes overall development function.
                 • The SHI does overall project management in-house.
                 • The architect or QS is appointed as PA (based on who is the best person for the
                    job rather than the profession they represent).
                 • Other consultants (QS, consulting engineers) are appointed as normal for design
                    and supervision of their aspects of the work, under the direction of the PA.

                 Model two (for larger and more complex projects where specialised input from
                 a variety of consultants and service providers is required):
                 • The SHI assumes overall development function.
                 • The SHI appoints an external professional PM.
                 • The PM is also given the role of PA.
                 • Various professionals are appointed for design and limited consultation by the PM
                    on technical and contractual matters during the contract administration phase.

                    For estimating and feasibility study purposes, the important thing to
                    remember is that if a PM is appointed without taking on the role of
                    PA as well, then the PM fee should be reduced accordingly because
                    the person who acts as PA will be receiving payment for that function.
                    Likewise, if the PM is also the PA, the PM fee should be higher, and
                    the client should ensure that no other member of the team (such
                    as the architect, QS or engineer) is being paid a PA fee as well. A
                    duplication of fees could add up to 2.5% of construction cost to the
                    overall project cost, without adding any real value.

                 Disbursements (Out-of-pocket expenses)
                 Professional fees are like a salary paid to the consultants for their time and effort,
                 with a profit component to compensate them for risk. In addition, consultants
                 have out-of-pocket expenses (disbursements) that are not covered by their fees,
                 for example:

                                                                G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

• Plan-printing costs (on large and complex projects there may be hundreds or
    even thousands of drawings of which copies must be distributed to the client,
    the quantity surveyor, other consultants, contractors and sub-contractors, etc.
• Typing, printing and copying of specifications, bills of quantities, minutes of site
    meetings, etc.
• Travelling and sustenance for projects located out of town.

The above must be allowed for in the estimate, usually as a percentage of building
cost based on previous experience (usually 0.25% to 1.5% of building cost).

Municipal plan scrutiny fees
Before any construction project in an urban area can proceed, permission to do so
must be obtained from the building control section of the relevant local authority.
This involves scrutiny of the plans by their officials in different departments to ensure
that the plans conform to their requirements in terms of the health and safety of
occupants and the public, traffic safety (entrances and exits on busy roads or near
blind corners, etc.), town planning and development control measures, etc.

The local authority usually charges for this service at a rate per square metre of
building area, for example:

 For areas with building work only:                 10 000m2 @ R 7.00/m2       R 70 000
 Additional charge for sections with drainage:       9 000m @ R 2.00/m
                                                            2            2
                                                                               R 18 000
 TOTAL                                                                         R 88 000

Sundry legal and administrative costs
If the anticipated costs of the sundry legal and administrative costs are not known,
an allowance should be made, e.g. R20 000-R50 000.

Initial marketing costs
Ongoing marketing and tenant recruitment costs during the operational life of the
building are considered an operational expense against income. To fill the units
initially though, a marketing and recruitment campaign may be necessary.

The costs could take the form of fees and expenses to do promotions and advertising,
spotting and recruitment commissions to “runners” who bring successful applicants,
etc. Allowance should be made for initial marketing costs, even if the SHI believes
that the outcomes of the socio-economic survey and market-survey will automatically
lead to signing up of tenants without having to market the product.

Development contingency
In addition to the design and detail and building contract contingencies allowed
under escalated construction costs, an overall development contingency should be
included. This may range from 0.5% to 2.5% of TDC/TCO.

                 Finance costs
                 In the process of securing project finance, there will be administrative and legal
                 costs such as:
                 • Raising fees/originator fees (sometimes “hidden” and paid off in the loan
                 • Valuation fees
                 • Mortgage registration fees and duties (lawyer’s fee and deeds office)
                 • Structuring fees where one financial institution acts as main lender in a consortium,
                    and undertakes to “structure” the total financing package in collaboration with
                    other institutions.

                 Interim cost of capital
                 Social housing projects are usually funded through a combination of subsidies, other
                 grants, loans, and in very rare cases with some equity (own capital) contribution from
                 the Social Housing Institution itself. Some of this money is “free” (i.e. not repayable,
                 or repayable but at no interest) and some of it comes at significant cost. The interest
                 charges that form part of monthly loan repayments during the operational phase are
                 an operational expense. During the development period, however, some draw-downs
                 will be made on the loan(s) to pay developers, contractors, suppliers, professional fees,
                 etc. From the moment a draw is made it bears interest. The interest accumulated on
                 such draws is added together, “capitalised” up to the end of the development period,
                 and included as part of TDC/TCO.

                 Interest charges apply to all “normal” loans obtained from financial institutions such
                 as the National Housing Finance Corporation (NHFC), Mpumalanga Housing Finance
                 Company, and any of the commercial banks.

                 We calculate interim or capitalised cost of capital in one of two ways:
                 1. The “short” method:
                    • Split the TCO into an initial once-off outlay (e.g. land cost), and a spread
                      outlay (e.g. construction cost and fees).
                    • Calculate compound interest on the once-off outlay over whole development
                    • Calculate compound interest on the spread outlay over the construction period
                      with cash-flow factor (0.4-0.6) to account for the spread nature of the spend.
                 2. The “long” method (more accurate but time-consuming):
                    • Estimate development cash-flow.
                    • Calculate interest on each net monthly cash-flow from the time of the cash-
                      flow up to the end of the development period.

                  Note: Examples of how to calculate interim cost of capital with both methods
                        are given in Annexure B.

Estimated net project operational income
(gross income less operational expenses)
The net operational income after expenses (but before loan repayments and tax)
must be estimated before rates of return can be calculated, and before cash-flow
projections can be done.

Gross operating income is the “theoretical” total income that could be derived
from renting out full-time, without vacancy or bad debt, all residential units, facility
spaces (e.g. child-care facility), commercial spaces, and parking bays, together with
any recovery of operating expenses through levies (only in certain types of leases),
and sale of electricity, where the SHI is buying it in bulk from the municipality and
distributing to individual tenants.

In practice, the theoretical gross income is never fully collected. Some vacancies
always occur (for instance, when units are vacated from time to time, and need
repair, or when a replacement tenant is not immediately available). In addition,
some tenants will default on rental payments, and leave without the arrears being
collected, resulting in some bad debt write-off. Usual practice is to target around
2.5% of theoretical gross income for each of the above (5.0% total), and the result
gives gross collectible income. Many SHIs allow for only 90% collection in
their projections, but this sets too low a target, and leads to complacency and
inefficiency in collection. In the risk analysis at the end of the feasibility study, the
effect of a 90% collection rate can be illustrated in the “pessimistic” scenario.

Property operating expenses which are not recoverable through levies must be
deducted from gross collectible income to give net operating income before loan
repayments and taxes if applicable.

Property operating expenses usually include:
• Local authority charges:
   • Municipal property rates on value of land and improvements
   • Consumption and service charges on water, electricity and sewerage for
     common areas (remember that tenants should be responsible for their own
   • Refuse removal

• Regular maintenance and cleaning:
   • Cleaning service
   • Building maintenance
   • Gardening and grounds maintenance
   • Lift maintenance (where applicable)
• Provisions and sinking funds:
   • Long-term maintenance (depreciation and replacement allowances)
   • Non-recoverable rent provisions (if not allowed for under bad debt allowance
     in collectible income above)

                 • Insurances:
                    • Property insurance
                    • Public liability insurance
                    • Loss of income insurance (if applicable)

                 • Other property costs and services
                    • Security
                    • Tenant relations (newsletter, facilities, contributions to activities)
                    • Auditing fees

                    NB: Be careful not to include general institutional management and
                    overhead costs such as office rental, the CEO’s salary and other
                    general staff salaries here. For once-off developments, it is normal
                    to allow in property operating costs for property management and
                    rent collection, including:

                    • Service provided in-house (staff costs, cost of system
                      amortisation and maintenance, ASDL lines, stationery).
                    • Outsourced (fee to service provider plus internal support
                    SHIs are meant to be long-term institutions that will develop and
                    manage many projects over time. It is therefore more appropriate
                    to allow for the above costs as a general overhead servicing
                    more than one project. These would not, therefore, be included
                    as property operating costs allocated to a particular project,
                    but rather as an overhead paid for out of the contributions to
                    overheads from the individual project cash flow surpluses.

                 Estimated project returns
                 Project returns can be measured in many different ways, ranging from simple initial or
                 first-year return on investment, to a number of more sophisticated discounted cash-flow
                 type analyses (such as Net Present Value or NPV, internal rate of return or IRR).

                  Note: Project returns on investment are calculated by using net income before
                        repayment of loans and income tax (where applicable). Loan repayments
                        are, however, taken into account when cash-flows (and budgets!) are
                        compiled. The reason for this is simple: Returns are estimated in order
                        to compare investment opportunities. Whether the money (which you
                        don’t have anyway) is invested in shares, the bank, or in the property
                        development project, it would have to be borrowed in all cases at same
                        cost of capital. Loan repayments would therefore be common to all
                        alternatives, and it is not necessary to complicate the calculations with
                        that factor.

                                                                        G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

• Initial or first-year return on investment = first year net income/TCO
    This is calculated by dividing the estimated net annual income for the first year
    by the TCO and multiplying this figure by 100 to give a percentage. For example:
    first-year return on a 100-unit block of flats with a TCO of R9 000 000:

 Gross rental income, two-bed units: 100 flats @ R 1 000 p.m.               R      100 000
                                                            X12 =           R    1 200 000 p.a.
 Less: Provision for bad debt and vacancy 5%                                R       60 000
 Gross collectible income p.a.                                              R    1 140 000
 Less:Property operating costs                                              R      280 000
 NET INCOME FOR FIRST YEAR                                                  R      860 000
 Initial (first-year) return = R860 000/R9 000 000 x 100 = 9.56% p.a.

The main problems with this measure are as follows:
• Apart from using escalated development costs and operational incomes and
    expenses, it does not take into account the value of money over time, or the
    total and uneven spread of amounts invested and income collected over the
    economic life of the building.
• It assumes that the project reaches full maturity from month one, i.e. target
    occupancy and bad levels are achieved straight away, which is not realistic. It
    presents the initial return as if it were the average return on investment (ROI)
    over the operational life of the project, which is a good indicative measure of
    overall project viability.

The major advantage of this measure is that income and expenses do not have to be
escalated too far into the future. This makes the projections more accurate (than say
a 20-year projection), and more easily understood in terms of the current value of
money. (Remember that even if it is acceptable for the calculation of estimated
return to assume an ideal situation from day one, the reality of lower initial
uptake [reduced initial income], and possible additional expenses in ironing
out early snags must be reflected in cash-flow and budget projections.

If assumptions are realistic, and estimates of both time frames and costs are done
properly, the initial return is often a better indicator of the health of a project than
the more sophisticated long-term cash-flow analyses used in financial modelling.
Long-term projections usually ignore possible cyclical fluctuations in inflation and
interest rates (i.e. assuming fixed or average rates over the period of study).

    NB: It is also important to remember that if the initial return
    shows that a project in its current form is not viable, no amount of
    manipulation of long-term projections will make a difference to the
    real problem of wrong project conceptualisation.

• Return on investment (ROI)
    This is a further development of the previous method where the simple return for
    each year over a 20-year period is calculated taking into account escalations in
    rental income and operating costs, and then averaged out to give the average ROI
    over 20 years. It still does not take into account that income and expenses

S H F BP6 2006

                    are spread over the year for each year, and not incurred or collected in one
                    go at the end of the year, but it is a slight improvement on the initial return
                    method, as the realities of first year(s) of operation could be accounted for in
                    the averages.

                      determined operational life-span of the project is discounted to its present
                      value, using the desired rate of return as the discount rate. If the NPV is
                      equal to or more than the TCO, then the desired rate of return has been
                      achieved. If the NPV is less than TCO, then the rate has not been achieved.
                      For example:
                    • CO on a project is R10 000 000
                    • Desired rate of return is 12% p.a.

                         Year of operation        Net income (FV)                 NPV at 12%
                                 1                   R 2 500 000              n=1; PV = R 2 475 248
                                 2                   R 2 700 000              n=2; PV = R 2 646 799
                                 3                   R 3 000 000              n=3; PV = R 2 911 770
                                 4                   R 3 400 000              n=4; PV = R 3 267 333
                                 5                   R 3 900 000              n=5; PV = R 3 710 716
                                                                             Sum of PVs: R 15 011 866

                     In this case, the NPV of future net incomes is more than the TCO if discounted
                     at the desired rate of return, meaning that the actual rate of return achieved is
                     far better than the discount rate of 12%.

                    • Internal Rate of Return (IRR): The IRR is the rate at which the total net cash-
                      flows on the project during both the development and operational periods
                      has an NPV of zero. Where the NPV method works with a pre-determined
                      discount rate to see if it is achieved or exceeded, the IRR provides the rate
                      at the end of the calculation. (The IRR method assumes that all positive cash
                      flows are re-invested in the project at the discount rate). For the example
                      above, you would have to feed all cash-flows into the formula (or financial
                      calculator), and compute the rate.

                 For both DCF methods, the cash-flow must assume an end-value. Usual practice is
                 to take an operational life of 20 years and an end value equal to 100% of TCO

                 Working out these returns manually is an extremely laborious task. Detailed monthly
                 cash-flows for the whole 20-year period first need to be estimated, followed by
                 a compound interest calculation with different factors for each of the individual
                 monthly cash-flow entries. It is easier to use a financial calculator with DCF functions.
                 You will still have to do the cash-flow projection though, as that is part of the input
                 of variables into the calculator. Different makes of calculator have different key-
                 strokes for entering variables and computing answers, but they all come with good
                 instruction booklets that also explain the concepts and principles underpinning the
                 various calculations.

                                                                                   G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

• Pay-back period
                     The TCO is divided by the annual net income to show how many years it takes for
                     the project to pay for itself. For example:
 TCO = R10 000 000; net annual income = R100 000
 Pay-back period = R10 000 000/R100 000 = 10 years

Development and operational cash-flow
Monthly cash-flow projections are done for the development period and for the first 5
years of operations. Thereafter, yearly cash-flows are done for years 6 to 15, or years
6 to 20. Some people do 20-year monthly flows, but it is very difficult (and some say
impossible) to project that kind of detail so far into the future.

A cash-flow projection is a table of actual cash receipts and payments for every month,
or quarter, or year, as the case may be. It should not be confused with a budget (forward
financial planning) or an income statement (retrospective financial reporting). The purpose
is to be forewarned of any cash crises that may arise, and to help the SHI plan for and
overcome these.

Cash-flow tables are compiled by taking into account predictable or known events (e.g.
paying for land against transfer, paying a certain percentage of professional fees when tenders
are in, and so on), and by projecting expenditure spreads such as construction cost with the
use of predictive techniques such as so-called “S-curves”, and “Californian envelopes”.

For an “S-curve”, real expenditure patterns on past similar building contracts are analysed,
corrections made for out-of-the-ordinary events, and the results plotted on a graph.
The horizontal axis represents cumulative time (usually in months), and the vertical axis
represents cumulative expenditure. The plots are then averaged out to give a single trend
line. The result may look as follows:

                                           R 5.5

                                           R 5.0

                         Although these curves are commonly referred to as S-curves (if you look very carefully
                         you may see a flat S in the shape of the curve), they often do not show any marked
                         flattening out at the end of the contract period, and are more like a “C” lying on
                         its back at an angle.

                         From the above, a cash-flow table for an 8-month building contract with a value of
                         R5 300 000 can be read off as follows:

                         Compiling the base S-curves from historical data is a difficult task, and requires
                         some knowledge of statistical mathematics. A more practical method is to compile
                         a simpler table, using actual expenditure tables from previous similar projects as a
                         rough guide.

                         Let us say a R9m contract is spread over 9 months. The average expenditure should
                         be R1m per month, but the actual pattern would look different, with amounts smaller
                         than the project average being spent in the first two or three months (low turnover
                         work such as site preparation, foundations, structural frame); amounts larger than
                         average spent in the middle months as the tempo picks up (high turnover work such
                         as brickwork, plastering, roofs), and the curve levelling off again towards the end
                         as final finishing is done.

                         The actual expenditure table on the previous similar building contract may have
                         looked as follows:

Let us say the current project for which the estimate (and feasibility study) is being
done is an estimated R9.9m building contract, also spread over 9 months. The
average is now R1.1m per month, and the table above can be used to guide us in
compiling a projected cash-flow for the current contract as follows:

    6                       1 485 000                               Average plus 35%
    7                       1 320 000                               Average plus 20%

  TOTAL                    10 000 000

In this case, the estimator decided that because the current project has a larger
value, but still has to be completed in the same time as the previous one, a quicker
start is required. The percentages in the first few months were adjusted to be closer
to the average. In the end it becomes a balancing game where the percentages are
tweaked according to experience, data available and intuition.

Some important things to remember when doing cash-flow projections:
• Allow for a realistic uptake rate in income projections. (It is not possible to have
   300 or 500 tenants installed and fully paying within a month.)
• Allow for initially lower collection rates (70-80% for, say, the first 3 months) until
   all collection and administration systems are running smoothly and hand-over
   quality and maintenance issues have been sorted out.
• Allow realistic time-frames – development always take longer than expected.

Risk analysis
Financial viability studies are projections into an uncertain future, based on past
and current trends and assumptions. The question needs to be asked: how will
changes in variables or assumptions used in the calculations affect project returns
and sustainability? These questions are often called the “what if?” type questions,
e.g.: “What if, for loan-repayment purposes, the average interest rate over the term
is 12% p.a. rather than the 11% used in the calculations”; and “What if the rental
for a two-bedroom unsubsidised unit is only R1 400 per month, rather than the R1
600 per month used in the calculations?”

S H F BP6 2006

                 Typical variables that could be tested in a risk analysis are:
                 • Building cost rates
                 • Building cost escalation rates
                 • Initial rental structure
                 • Operating expenses
                 • Vacancy and bad debt factors
                 • Escalation in rentals
                 • Interest on loans
                 • Time frames (and therefore the effect of changes on escalations and other

                 It is usual to present three types of scenarios for each variable in sensitivity analyses:
                 • Optimistic (better than the assumptions used in the presentation of the viability
                 • Realistic (the same figures used in the study)
                 • Pessimistic (worse than the figures used in the study)

                 While a sensitivity analysis illustrates the effects of changes in underlying assumptions,
                 it does not predict the statistical probability of such risk events actually occurring,
                 leaving the decision-maker to speculate about that. In countries like the United States
                 of America, more sophisticated models such as the Monte Carlo Simulations are
                 used, which take into account probability predictions. In South Africa there is not
                 yet sufficient research data available to do meaningful simulations and predictions,
                 especially in the social housing sector.

                    and can question the basis on which these assumptions are made; or even ask
                    that they be changed (where the reader possesses better information than the

                 Notes to the reader (not part of the viability report):

                 1. Only one measure of return has been estimated below, namely the simple
                    initial or first-year return. The more sophisticated cash-flow analyses
                    (NPV, IRR) requires more detailed figure work such as long-term cash-
                    flow projections, and including these would unnecessarily burden the
                    reader without really enhancing the illustrative value of the guidelines
                    and examples.

                 2. For the same reason as above, less detail than would often be included
                    in real reports was provided in the following sections:
                    • Detail breakdown calculations
                    • Risk analysis
                    • Project specifications

                 3. In the example below, calculations were done as if there were no subsidy
                    or equity investment involved, i.e. the project was deemed to be 100%
                    loan funded. This is, of course, not realistic, but since funding structures
                    can vary so widely, the above was done in order to keep the calculations
                    simple for clear illustrative purposes. Also, at the time of going to press,
                    it was not clear how the new capital grant funding mechanism would be
                    applied on projects. In real situations, the viability study for each project
                    should take into account the funding structure for that project (and the
                    effect of subsidy funding on the marketing mix and capping of rentals for
                    subsidised tenants).

                 4. In the example, it was assumed that the project would be completed in
                    one phase, and would be fully operational from the first year of operation.
                    In reality, projects are often completed in phases over a number of years.
                    In such cases, one could either treat each phase as a project in its own
                    right (but this would not easily allow for proper apportionment of land
                    and town planning costs, for instance) or make provision for the phased
                    completion and receipt of income in one study. The problem with this is
                    that it becomes difficult to show viable initial returns, because the early
                    phases are overburdened with costs that are incurred early on, but for
                    the ultimate benefit of the whole phased project.

 Executive summary
 Brief project description:
 The project comprises 180 two- and three-bedroom flats for rental in six three-storey walk-ups on erf number
 2305/2, Bigtown Extension 17, distributed as follows:

   36 three-bedroom flats x 46m2                     1 656m2
   144 two-bedroom flats x 38.5m2                    5 544m2
   Sub-total flats                                   7 200m2

 Operational period = 20 years from 1 April 2008

 Project funding structure and conditions
 The total project capital cost of R34 879 938 is funded via an NHFC loan over 20 years @ 10.5% p.a.

 Loan repayments (capital and interest):
 R348 234 per month x 12 = R4 178 808 per year

 Statement of financial objectives:
 The company’s financial objectives with this project are:
 • Initial return: 11.0% p.a.
 • Total project cost ceiling: R32 472 000 (R4 100/m2)

Estimated project returns, and how they compare with the stated
Initial return = 7.7% p.a.

This compares unfavourably with the stated objective of 11.0% p.a.

Conclusions and recommendations
In its current form the project does not meet any of the stated financial objectives, nor will the estimated
net income be sufficient to carry both operational expenses and loan repayments. (The annual shortfall
in the first trading year = R1 135 814 after loan repayments, which accumulates to approximately R4.5m
plus interest before income meets expenses and loan repayments in the 8th year of trading only – see
operational cash-flow below.)

All possible savings in construction cost and operational expenses have already been considered in the
calculations below. Alternative funding structures with the incorporation of institutional subsidies have been
analysed, but because of the limiting effect of this on rental incomes, the situation actually looked worse. In
order for break-even between income and expenses to be achieved from year one, equity grants to the value
of R9 580 000 plus VAT would have to be injected into the capital funding for the project.

The recommendation to the board, therefore, should be that the project is not to be proceeded with in
its current form, but that it be re-conceptualised for a different target market, with different affordability
parameters. This will require a re-analysis of the social and marketing surveys, and possibly a new
demand study.

Notes to reader:
1. Professional fees were split into a once-off 60% payment at tender completion, with the balance paid in equal monthly payments
   spread over the construction period. In reality there will probably be stage payments during the planning phase as different “work
   stages” are completed.
2. Construction cost escalations are included in the monthly payments as if they are calculated and paid in the month to which they
   apply. In reality there is a lag time of 3-6 months in the publication of indices needed for calculating each month’s applicable
   escalation, which means that there will still be escalation and maybe other final account payments up to 6 months after contract
   completion. The liability is, however, incurred in the month in question, and it is therefore prudent to portray it as such so that the
   provision can be made timeously.
3. The interim cost of capital is reflected as a cost in the estimated TCO elsewhere, but is not included in the cash-flow above. This
   is because the usual practice is for it to be capitalised at the end of the development period, added to the loan amount, and
   amortised (paid off) over the term of the loan as part of the monthly instalment. It is therefore not a cash expense in the development
4. If there were some equity investment, the table above would show the cash-flow demand (and maximum requirement) on equity
   and loans separately, so that the SHI could plan for the availability and release of own funds which may be tied up in investments,
   or may have to be diverted from other provisions on a temporary or permanent basis.

 Notes to reader:
 1. The operational cash flow can be done for 5, 10, 15 or 20 years. In the example above it was done up to the point where there is a
    surplus after expenses and loan repayments. It shows that net income will be able to meet expenses and loan repayments only in
    the 8th year of trading, with an accumulated shortfall of almost R4.5m (plus interest). The project in its current form is therefore not
    sustainable from a cash–flow perspective, and should be re-conceptualised.
 2. Both income and expenses were escalated by 5% p.a., while loan repayments were kept static at the initial rate of interest. More accurately,
    the anticipated average interest rate over the term should be used for calculation of loan repayments, but the approach is that if loan
    rates were to change, it would generally be accompanied by related changes in inflation rates, meaning that income and expenses would
    change as well.

Notes to the reader:
General: The sensitivity analysis above is a much-simplified one just to illustrate the principle. It does not cover all the
variables that should normally be included in the analysis, nor does it show the effects of possible combinations of
changes, e.g. interest rates and vacancies rising at the same time. The possible combinations are theoretically endless
though, and it is part of the trouble with sensitivity analyses that they do not indicate the statistical probabilities of risk
events, or combinations of them, occurring.
1. Changes in construction cost will usually have a knock-on effect on professional fees, finance costs, interim cost of
   capital and development contingencies, all of which must be taken into account in calculating the effect on returns
   (and cash flows).
2. Changes in interest rate will affect the interim cost of capital, and the long-term loan repayments on the operational
3. Changes in rentals may, or may not, have a direct proportional effect on some of the operational expenses, but not
   on all of them. It may, for instance, change collection and management charges where these are a percentage of
   the rent roll, but will not have any bearing on municipal charges.
4. As above, vacancies and bad debts may, or may not, affect certain expenses such as collection and management. In
   addition, if higher vacancy and bad debt allowances are made, the question should probably also be asked whether
   one should not then increase expenses to allow for more marketing and vacated unit maintenance, as well as more
   intense credit control measures.

Alternative approaches to doing
project financial viability studies
Income capitalisation method of
determining financial viability
The way investors and their consultants often go about doing financial viability
studies is as follows:
1. Determine demand for product type and mix (one-/two-bedroom flats, etc.).
2. Develop concept design and work out development cost estimates.
3. Determine what the rentals should be to justify the cost.
4. Find out too late that the projected rentals were too optimistic, and that the
   detail design and documentation are based on unaffordably high product

A more prudent approach involves first determining realistic rental levels affordable
to the target market, and then “forcing” the design to result in a development cost
that is viable within the constraints of realisable income. This technique is commonly
used in commercial developments, and is called the income capitalisation method
of setting development cost targets or limits. In simple terms, it works as follows:

1. From the social and market surveys, determine the product demand as before,
   and then set realistic rentals for the different products.
2. Calculate the estimated total net income that could be realised on the basis of
   those rentals.
3. Divide the net income by a capitalisation rate (cap rate for short) acceptable to the
   investor (in other words, the investor’s desired rate of return on the project).
4. The result of the calculation in 3 above is the total allowable amount of total
   development cost (TDC) or total capital outlay (TCO) that must be adhered to
   if the desired rate of return is to be achieved at the determined rental levels.
5. From this amount, deduct the known cost of land, and then do a residual value
   calculation to eliminate interim finance costs and professional fees, leaving a
   balance that could be spent on actual building cost. This then becomes the cost
   parameter for design purposes.

                         Example of income capitalisation calculation:
                          Estimated net income from indicated product mix (based on market surveys):
                          100 two-bedroom units @ R1 150 p.m.                                    R 115 000.00
                          Less: Provision for vacancies and bad debt (10%)                       R 11 500.00

                          Less: Operating costs p.m. (rates, insurance, maintenance, etc.)       R 33 500.00
                          NET MONTHLY INCOME                                                     R    70 000.00
                          NET ANNUAL INCOME (R70000 x 12)                                        R 840 000.00

                         The investor must now decide on an acceptable cap rate. Deciding on an
                         appropriate cap rate is usually an exercise involving much debate and hand wringing
                         in commercial developments. One has to look at returns on alternative forms of
                         investment, and then make allowances for risk premiums, tax implications and the
                         like. Absa publishes statistics on commonly acceptable cap rates for a wide variety
                         of property developments. At the moment, these are around 10-11% on average.

                         For this exercise let us assume that the investor’s desired rate of return is 10% p.a.,
                         and that it decides on this figure as a cap rate. Now divide the net annual income by
                         the cap rate factor: 10% = 0.1:

                         R840 000.00 ÷ 0.1 = R8 400 000.00.

                         The allowable TDC is R8 400 000.00 (Check the reverse calculation: R840 000.00
                         net income over R8 400 000.00 TDC gives an initial return of 10% p.a.)

                         Now calculate the residual building cost:

             Allowable TDC                                                                   R 8 400 000.00

                         The above is equivalent to R5 500 000/100units = R55 000 per unit.

                                                              G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

If we know that the current building cost for two-bedroom units in a walk-up is say
R1 800/m2, our allowable size is R55 000/R1 800 = 30.55m2. Now the question is
whether or not 30.55m2 for a two-bedroom unit is a marketable size for a rental of
R1 150 p.m. The answer is probably no, so we must look at it from the marketing
side and say that the units must be at least 42m2, meaning that the allowable current
building cost rate is R55 000/42 = R1 310/m2. Is this feasible or will it result in too
low a specification and quality? We have to reach a workable compromise between
realistic income, and a marketable but affordable product. We will have to try
different product and tenant mixes, where some units can be let at market-related
rentals to non-subsidised tenants in order to make the scheme work.

We can short-circuit the above calculation by taking the allowable TDC of
R8 400 000, dividing it by the number of units (100) = R84 000/unit, and checking
that against the known TDC rate (say R2 700/m2), which again gives a size of around

The process should proceed more or less as follows:
1. The concept is validated against the target market demand as found in the results
   of the market survey.
2. The residual allowable TDC and current building costs are determined through
   the income capitalisation method.
3. The design team is briefed on the cost parameters as determined above (indicative
   unit sizes and specifications based on the cost parameters, but always checked
   against marketability and long-term maintenance implications).

This means there needs to be constant interaction between the design team
on the one hand, and the marketing and property management teams on the
other, and it is up to the development manager and/or project manager to
ensure this happens!

4. The design team prepares a preliminary concept or sketch design, and the QS
   does a cost estimate and preliminary viability study. If the estimate falls within
   the cost parameter, OK, if not – it is back to drawing board. Savings could be
   achieved through:
   • Reducing unit size and specifications (but not below marketable levels, and
     not in a way that will result in maintenance problems).
   • Simplifying complicated building shapes and details, improving layouts to
     shorten service pipe runs, improving design efficiency i.e. achieving the
     optimal ratio between lettable and common spaces respectively.
   • Consulting with property and marketing managers to see if certain facilities
     and amenities could be provided in rudimentary form initially (or even left
     out), and gradually introduced or upgraded in a phased manner as income
     improves or additional donor funding is obtained.

                 Note 1 (Interim capitalised finance cost): Doing this calculation accurately is a
                        complicated process, which your QS should be able to do. It involves
                        some financial mathematics with compound interest calculations in
                        reverse. What you need to understand is that a portion of interim
                        finance cost (capitalised interest) will accumulate from an early date as
                        you draw down on the loan to pay for land, and a substantial portion
                        of professional fees will be payable at documentation and tender
                        stage, while the major part of interest will accumulate progressively
                        over the building period as draw downs are made to pay monthly
                        progress payments to the contractor and professionals. Don’t forget
                        the initial finance charges such as bond valuation and registration
                        fees, originator’s commission and/or structuring fees, if applicable. For
                        illustrative purposes in this example, we assume an interim finance
                        cost of 10% of TDC.

                 Note 2 (Sundry development costs): This includes allowances for interim
                        capitalised rates and taxes, municipal plan scrutiny fees and incidental
                        costs such as legal agreements, market surveys, marketing and
                        promotion costs, etc.

                 Note 3 (Building cost escalation): Again, this is a complex calculation similar
                        to the interest calculation above, but accumulating on reducing
                        balances rather than accumulating balances. The full amount of the
                        current building cost will escalate at tender market rates (projections
                        available from Stats SA and the Bureau for Economic Research,
                        Stellenbosch University) during the pre-contract planning period. As
                        monthly progress payments are made and taken out of the escalable
                        amount, the reducing balances will escalate at contractual escalation
                        rates (based on indices supplied by Stats SA).

                 Residual land value calculations to determine a realistic/affordable price that
                 can be paid for land:

                 In the above examples, we worked on the premise that the land cost was known
                 and fixed. This is not always the case. Sometimes we need to check the asking price
                 against what we can afford, to enable us to negotiate the price on a realistic basis.
                 Sometimes we will still need to search for suitable land. In that case we could do
                 a hypothetical calculation (say 500 units at a certain density and price, and for a
                 certain target market as identified in our social/market survey). We could also do
                 an estimate of what the total development cost should be, in order to render an
                 acceptable return by using the income capitalisation method as above.

                 The same principles as above can then be applied to determine what the maximum
                 price is that can be paid for a piece of land, and the search for suitable land will
                 then narrowed down to properties that fall within that price range.

                 100% loan funding [no equity investment] for
                 illustrative purposes)
                 The following is an example of a very preliminary quick method of estimating
                 building and development costs, and a rough viability study which is done before
                 any drawings are available. It may be used in cases where the investor/developer has
                 seen a site that attracted their attention because of its location or some other feature
                 that indicates development potential, and they wish to do a quick investigation
                 into whether or not it warrants further work in the form of sketch designs and more
                 detailed feasibility studies.

                 Information with regard to size, development rights, etc. of the site is obtained
                 from the town planning office of the local authority, and is used to calculate gross
                 construction or floor areas of the different types of buildings that are permitted on
                 the site in terms of the “Town Planning Scheme” of the local authority.

                 • Area – 10 000m2 (= 1 Ha)
                 • Current zoning – Residential (flats)
                 • Coverage – 40% (which means that “footprint of all buildings at ground level
                    may not exceed 40% of site area”)
                 • Floor Space Ratio (FSR) or bulk – 1.2 (means the total covered floor area of all
                    buildings at all levels may not exceed 1.2 times the site area)
                 • Height restriction – 13m (4 storeys if flat roof, 3 storeys if pitched roof)
                 • Building lines – 9m in front, 5m at back and sides
                 • Municipal valuation – R800 000 (approx. 80% of market value)
                 • Municipal land tax – R0.10/R p.a.

• Professional fees and disbursements:
   • 10% of escalated building cost

Other assumptions:
• Time required for project validation and appraisal: 2 months
• Time required for purchase and transfer of the property: 2 months
• Design development, and documentation: 4 months
• Plan approval: 2 months
• Tenders: 2 months (but overlaps for 1 month with plan approval)
• Total planning period: 11 months
• Construction period: 13 months
• Total development period: 24 months
• Bond registered in month 4

The project will be 100% loan financed (this of course not realistic, but is assumed
just to simplify the calculations below)

In this case, for the sake of simplicity, no township establishment or rezoning is
involved. Costs would include application and advertising, town planner and land
surveyor fees, development contributions to local authority and so on. Theoretically,
the developer could, in order to save time, assume some overlapping of the above
processes. If he is reasonably certain, for instance, that he will purchase the property
if this quick feasibility study indicates a positive result, and if he is confident that the
rezoning application has a good chance of succeeding, then he could submit an
application for rezoning in the name of the seller as soon as his offer to purchase has
been accepted, and before transfer of the property has taken place. The rezoning
process involves approval by various departments within the local authority, as
well as a period of usually about two months during which the proposed rezoning
is advertised to invite objections from the public and interested parties (e.g.
neighbours). As soon as the objections phase is over (this could be about two months
before final approval), the developer could take a chance and ask the professional
team to start the documentation and procurement for construction.

The above is a high-risk approach to feasibility studies, however, as many things
could go wrong before final approvals are obtained, and the developer could end
up paying for a lot of work which may be fruitless in the end. In this example, we
follow the low-risk approach with minimal overlapping. The total development
period therefore, is 24 months, made up as follows:

 Planning period: 11 months
 Construction period: 13 months

                 With the information above, the estimator can now do the following calculations:

                  Total area of site that may be covered with buildings – 40% x 10 000m2 = 4 000m2
                  Total permissible floor area of buildings at all levels – 1.2 x 10 000m2 =12 000m2

                 The obvious development configuration is 3-storey walk-ups (3 floors of 4 000m2 each
                 will comply with the allowable bulk and total height restriction on the site of 13m. From
                 experience we know that we should add approximately 5% to the building area for
                 service areas, cleaners’ stores and electrical switch rooms. These areas are not counted
                 in the FSR. Our total building area is therefore, 12 000m2 + 5% = 12 600m2. (We
                 will assume that all the service areas will be on ground level.)

                 We will also assume that, from our general market knowledge, we know that the
                 most popular accommodation is 2-bedroom flats of 40m2. We also know from past
                 experience that design efficiency for this type of building is 90% (meaning that 90% of
                 our 12 000m2 or 10 800m2 is available for flats, with the remaining 10% being used
                 for stairways and other circulation areas). We can therefore, fit 10 800 m2/40 = 270
                 units on the site.

                 The next critical aspect is parking. Available on site is an area of 5 400m2 after deduction
                 of ground floor built area of 4 600m2. Of this, about 600m2 is unsuitable (rocky outcrop
                 and wetland in SE corner), leaving 4 000m2. We estimate that another 1 300m2 is
                 needed for garden and recreational areas, refuse yards, walkways, etc., leaving only
                 2 700m2 for parking on site. At 30m2 per car, this gives us space for 90 parking bays
                 on site. The total parking requirement as laid down by the local authority is 0.25 bays
                 per unit = 270 x 0.25 = 68 bays (2 040m2 of paving). (In practice, it is usually a lot
                 harder to satisfy the parking requirement.)

                 We can now do a quick financial viability calculation as follows (or preferably using
                 the income capitalisation approach illustrated earlier):

                                         will contribute to general management expenses (overhead costs). The
                                         rough indication of initial ROI in this case suggests, however, that it
                                         may be worthwhile to spend a bit more time and money on proper
                                         detailed feasibility studies, and perhaps even to try to obtain an option
                                         on the land for a month or two to allow time to carry out such studies
                                         without fear of losing the land to other interested parties.

Contract Price Adjustment Provisions Of The JBCC
(Formerly Known As The Biac (Haylett) Formula)
A Manual and Reference Guide for practical application of the formula is published by and available from
the Joint Building Contracts Committee (JBCC), with revisions and interpretations issued from time to time.
Students are advised to obtain a copy of this manual, and to continually keep up to date with new revisions
and interpretations.

How the provisions work
•   The CPAP provides for the adjustment of contracts in respect of:
    •    General and industrialised building work.
    •    Subcontract work carried out by nominated, selected and non-nominated subcontractors.
    •    Direct contract work comprising specialist and engineering installations related to building projects.
•   Standard composite indices have been compiled in consultation with CSS to include the weighted labour,
    material and plant components applicable to a number of defined work groups. CSS in Statistical Release
    P0151 publishes these composite indices each month.
•   In brief, the CPAP operates as follows:
    •    A number of work groups are defined into which the work contained in a building contract can be
    •    CSS publishes a like number of sub-indices, reflecting price movements of labour, material and plant
         content of each work group.
    •    The principal agent values the work executed for certificate purposes in the normal way but, in addition,
         he or she allocates the value of the work to the respective work groups.
    •    In a particular month, the value of the work certified in each work group is adjusted in relation to the
         movement in the index value for the applicable month compared with the index applicable at the
         tender date. This is done so that the work executed in a particular period is adjusted in relation to the
         index value for approximately the same period.
•   The work groups have been restricted to a practical number to limit and simplify the work required at the
    time of certification.
•   The approach adopted is that certain materials lend themselves to grouping for costing purposes and
    consequently reference is made to “work group” rather than “trade” as is customary in documentation
    in the building industry. For example, steel windows, steel door frames and suspended steel ceilings are
    assembled to limit the number of groups, as the materials originate from the same basic source and the
    percentage fluctuations in labour costs are likely to be similar.

Calculation of adjustment
•    The principal agent will calculate an amount of adjustment for each valuation period in respect of each
     work group using the formula:
          A = 0.85 V ( Xo - 1)


          A        =     the amount of adjustment
          0.85     =     a constant which provides for a 15% non-adjustable element
          V        =     the work value for adjustment in such work group and the valuation period
          Xe       =     the value of the index applicable to such work group and the valuation period which
                         shall be the value for:
                         (a) The month before that during which the progress certificate is dated in respect of
                             certificates issued up to and including the 15th day of the month
                         (b) The month during which the progress certificate is dated in respect of certificates
                             issued after the 15th day of the month
          Xo       =     the value of the index applicable to such work group for the base month

Contract Price Indices
Due to continuous inflationary escalation in the cost of labour, materials and other resource inputs, a contract
price index is vital for updating past records used for estimating purposes.

At present there are two bodies that provide the building industry with contract price indices together with other
relevant statistics on a continuous basis, namely:

1. Bureau for Economic Research, University of Stellenbosch
    This bureau publishes two quarterly publications namely Building and Construction and Trends in Building
    Costs. The first of these is distributed to firms who pay a certain annual subscription fee whilst the second
    publication is distributed free of charge to all participating quantity surveying firms. (Participating QS firms
    are firms who analyse certain bills of quantities and submit the information on a standard form provided by
    the bureau.)

2. Central Statistical Service: Contract price index for buildings
    This is a monthly index that is distributed to all quantity surveying firms. All firms are compelled to provide
    information to the Central Statistical Service on its prescribed standard forms on a continuous basis.

Estimating Pre-tender Escalation On Construction
The starting point for all construction cost estimates is the day on which the estimate is done. In other words, the
rates used are those applying on that day as if the project could be completed on the same day. this is usually
called the “estimated current construction cost”.

Starting and completing construction on the very same day is, of course, not possible. Feasibility studies (of
which the estimate of construction cost is an important part) first have to be carried out, tender documentation

                                                            G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

must be prepared, tenders called for and adjudicated, plans submitted for scrutiny, and permission received
from the local authority to start building, etc. This can take from 4-12 months or even longer on large and
complex projects.

During this time, construction costs will fluctuate in response to both macro-economic and local construction
market factors. Recently, these fluctuations have almost always been upwards as a result of continued inflation,
and are expected to remain that way for the foreseeable future.

The anticipated future tender price for the work will invariably be higher than the estimated current construction
cost. The estimated current construction cost must therefore be escalated for the estimated total planning period
at a projected rate based on construction market trends.

Example: Estimating Pre-tender Escalation (Or Escalation During
Planning Period):
Basic information:
•    Estimated current building cost:            R 10 000 000
•    Estimated planning period: 6 months
•    Anticipated rate of escalation in construction market prices for next 6 months: 1.25%/month

Estimated escalation during planning period:
Using the formula for compound interest Sn = K(1 + i) n , and the following values for the symbols:
•    K or initial capital or present value = R 10 000 000
•    i or escalation (interest) rate = 1.25%
•    n or number of periods = 6

The compounded future value can be calculated.

In this case, the interest or accumulation factor is 1.07738, and the future value or estimated tender sum is
1.07738 x R 10 000 000 = R 10 773 800. The pre-tender escalation is therefore the difference of R 773 800.

The anticipated tender sum is R 10 773 800.

    If calculated with a financial calculator:

    PV = R 10 000 000; n = 6; i = 1.25

    Compute FV, subtract PV, and the difference is the escalation.

S H F BP6 2006

Estimating Post-tender Escalation On Construction
“Short” Method (Less Accurate Than Longer Method)
Escalation During Tender Adjudication Period:
Once tenders have closed, the base-date or starting index for construction contract escalation is fixed (this
usually happens in the month before the closing of tenders if tenders closed before the 15th, and the month in
which tenders closed if after the 15th day of the month). This means that while tenders are being adjudicated,
escalation on the tender sum is running.

A different type of index is now applicable in accordance with the contract conditions for civil engineering and
building projects.

Example: estimating contract escalation during tender adjudication
period – short method, building contracts using cpap, haylett formula:
Let us assume in the example above, that the estimate was exactly right, and that the lowest viable tender came
in at R 10 773 800 (highly unlikely of course). We will also assume that tender adjudication will take one month.
The entire 85% of the tender sum that is subject to escalation will escalate for a month before construction even
starts. If the projected contract escalation rate is 0.5% per month, the escalation during tender adjudication will
be calculated as follows:

K (or PV) = R 10 773 800 x 0.85 = R 9 157 730
i = 0.5%

The compounded future value as calculated or read from the tables is then: 1.005 x R 9 157 730 = R 9 203 519.

In other words, while the tender was being adjudicated, the building cost escalated by R 45 789
(R 9 203 519–R 9 157 730)!

The building cost has therefore gone up in this time by R45 789, from R 10 773 800 to R 10 819 589.

This means that by the time the builder gets the go-ahead to go onto site and start work, the building
cost has already gone up to R10 819 589 from the tender price of R 10 773 800.

   If calculated with a financial calculator:
   PV=R 10 773 800 x 0.85=R 9 157 730; n=1; i=0.5
   Compute FV, subtract PV, and the difference is the escalation.

Escalation during construction:
Expenditure curves on construction contracts usually show that more money is spent during the second half of
the contract period (because of slow starts, site establishment, high volume/low value work in the early stages,
etc.) The effect of this is that more than 50% of the contract value is subject to escalation for longer than the
average period that each payment would have been subject to escalation if expenditure had been spread evenly
across the contract period. This is sometimes referred to as the “cash-flow factor”, or the “S-curve factor”, which
can be anything between 0.4 and 0.65.

                                                                      G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

Example: estimating escalation during construction
(short method, building contracts using CPAP haylett formula)
Assuming a factor for our example of 0.6, estimated escalation during construction for our example above,
would be as follows:

Basic information:
i = 0.5%
K (“Vtotal” x 0.85 x 0.6) = R 10 819 589 x 0.85 x 0.6 = R5 517 990

Estimating the escalation:
R 5 517 990 x 0.02015 = R 111 187

Estimated final escalated building cost in accordance with the short method:
 1. Estimated current building cost                    R 10 000 000
 2. Estimated pre-tender escalation                    R   773 800
 3. Estimated tender sum                               R 10 773 800
 4. Estimated post-tender escalation:
    4.1 During tender adjudication:        R 45 789
    4.2 During construction:               R 111 187   R   156 976
 Estimated final escalated building cost               R 10 930 776

   If calculated with a financial calculator:
   PV = R 10 819 589 x 0.85 x 0.6 = R 5 517 990; n = 4; i = 0.5
   Compute FV, subtract PV, and the difference is the escalation.

“Long” method (most accurate method)
 Note: In this case it will not be necessary to calculate the escalation during the tender adjudication
          period separately, as you will see in the example below.

From the end of the first month of construction activity, the contractor will receive progress payments. An amount
of 0.85 of the value of each progress payment will only escalate from the base date to the date of certification,
and no further.

To estimate the escalation on each payment, a construction cash-flow or payment projection must first be made.
Estimated escalation for each monthly payment must then be calculated, using the relevant contract adjustment
formula and the projected escalation rates for the construction period.

Worked example 1: estimating escalation during construction
(Long method, building contracts using cpap, haylett formula)

Basic information:
1. Projected contract escalation rate during construction: 0.5% per month

2. Projected construction cash-flow or payment schedule:

 Note: that n for the first payment = 2 (one month tender adjudication before construction starts! – first payment
       only two months after tender closing: this takes care of the escalation taking place during the adjudication

Estimated final escalated building cost in accordance with the long method:
 1. Estimated current building cost                                R 10 000 000
 2. Estimated pre-tender escalation                                R      773 800

 Note: In this example, the figure calculated using the long method differs by only R8 997 from the short method,
       but the differences can be far greater if the “cash-flow factor” is chosen differently for the short method.
       If in the above example, for instance, a factor of 0.5 was used in the short method, the calculation would
       have looked as follows:

Basic information:
i = 0.5%
K (“Vtotal” x 0.85 x 0.5) = R10 819 589 x 0.85 x 0.5 = R4 598 325

Estimating the escalation:

R4 598 325 x 0.02015 = R92 656 instead of the R111 187 for a factor of 0.6.

Calculation of interim cost of capital during development
The SHI can obtain capital required for construction or property development projects from different sources,
such as:
•   Equity or own capital (from own accumulated cash reserves/investments) – this is currently rare as most
    SHIs are struggling just to meet operational expenses, let alone put away surpluses
•   Government subsidies and grants, and donor grants
•   Loans from financial institutions and aid agencies

In theory, all project capital comes at a cost. If it is borrowed, there is usually an interest charge. Equity invested
in a project is withdrawn or withheld from being invested elsewhere, thus losing out on the opportunity to be
earning interest, capital appreciation, dividends or operating profit depending on the alternative (investment in
bank, property, stocks and bonds, or stock for trading). This loss of potential interest or other form of return or
yield is referred to as the opportunity cost of equity. In practice, subsidies and grants, and interest-free loans
are considered to be “free money” that comes at no cost to the property developer (SHI).

Capital is invested in a project in varying amounts from time to time during both the planning and execution
phases. As soon as a certain amount is spent (invested), it either loses interest or the opportunity to provide
yield (equity), or it attracts interest charges (borrowed capital). Both opportunity costs on equity, and interest on
amounts borrowed (to pay for land, professional fees, construction and so on) during the development period
must be calculated up to the end of the development period and “capitalised” or included in the total capital
outlay or project development cost. The sum of these constitutes the interim cost of capital.

For purposes of estimating and feasibility studies, interim cost of capital can be calculated in one of two
•   Using the so-called long method – done on the basis of a detailed project cash-flow, and therefore, more
    accurate (but also quite time-consuming)
•   Using the so-called short method – done without a detailed cash-flow of expenditure, and therefore, less

The long method of estimating interim cost of capital
In this method, a detailed monthly cash-flow projection for the development period must be drawn up first. The
interest/opportunity cost for each month’s expenditure then needs to be calculated from the time the expenditure
takes place up to the end of the development period.

Worked example: estimating interim cost of capital during development
period (long method)
Basic information:
For calculation purposes, each actual expenditure (investment in the project) is the Present Value (PV) of that
investment. The period from the date of investment up to the end of the development period is the term of the
investment (n). The opportunity cost/interest charge is then calculated for that term by using the opportunity
rate or the interest rate, as the case may be. To simplify the illustration of the principle, in the simple example
below no distinction is made between equity and borrowed capital (i.e. all the “investments” are considered to
be either equity or borrowings, alternatively opportunity rate on equity and interest rate on borrowings taken as
equal: 10% p.a. nominal rate in this case, or i = 10% p.a.)

The total estimated cost of capital during the 6-month development period (2 months’ planning, 4 months’
construction) is R 23 689.00.

The short method of estimating interim cost of capital
If expenditure were spread evenly across the contract period, 50% of expenditure would have been incurred
when 50% of time had elapsed, meaning that on average only 50% (0.5) of the contract value is subject to interest
charges for the full 4 months; alternatively the full amount is only subject to interest for 50% of the time. This is
referred to as the “cash-flow factor”, the “S-curve factor” or the “spread” factor, which in this case is 0.5. This is
another way of saying that either the Present Value (PV) of the whole contract sum, or the interest rate (i) must
be multiplied by a factor of 0.5 (it doesn’t matter which one is adjusted).

As seen in the cash-flow table above (and in Annexure B), expenditure curves on construction contracts
usually show that more money is spent during the second half of the contract period (because of slow starts,
site establishment, high volume/low value work in the early stages, etc.) The effect of this is that less than 50%
(usually around 40%) of the contract value is subject to interest accumulation for half the time. In the example
above, 40% of construction contract value (R 120 000 + R 180 000 = R 300 000 out of R 750 000) is spent when
50% of the contract time (2 out of 4 months) has elapsed. The cash-flow factor is therefore 0.4. (We would not,
of course, have done the cash-flow for this particular project, but we would know the expenditure pattern from
analysis of previous projects, and from experience).

Using this factor of 0.4 for our example, the estimated cost of capital during construction would be as below.
We would still have to do separate calculations for lone-standing major expenditures such as land cost, fees
payable at tender stage and so on. For practical purposes, the balance of fees and other small expenditures
can be lumped together with construction cost and adjusted by the cash-flow or spread factor of 0.4:

PV of all spread costs (months 3, 4, 5 and 6):
40% of fees:     R 40 000
Construction: R 750 000
Marketing:       R 20 000
TOTAL            R 790 000 x 0.4 = R 316 000

FV (i = 10%p.a.; n = 4m):              R 326 666

The cost of capital = FV-PV = R 326 666 – R 316 000 = R 10 666
Add (calculated as per long method):
Cost of capital month 1:                             R 5 616
Cost of capital month 2:              R 2 542
TOTAL COST OF CAPITAL                                            R 18 824

This is less than the amount calculated via the long method (which is more accurate).

Key agreements that need to be put in place
A useful framework for guiding the drawing up of a critical path programme is to identify and arrange in critical
sequence all the key administrative approvals and project governing agreements needed, as these usually
take up the most time. The technical work taking place in between approvals and go-aheads is not normally
the problem. Some of these agreements and approvals are shown in the table below more or less in critical
sequence (you can think of more that apply to your specific case):

Some of the questions the programmer now needs to ask him/herself are:
•   What work needs to be done by the technical project team before an application for approval can be made, or
    a key agreement drafted, and how long will it take, including the research or information gathering stage? (e.g.
    How long for management to prepare a proposal to council requesting a land availability agreement?)
•   At what level are internal approvals required, and how long will it take? (e.g. The proposal for LAA must first
    get board approval for the selection of land as well as proposed terms – how long to convene board, must
    it first go through technical/legal/finance sub-committees, and allow for come-back and re-submission?)
•   How long does the external approval process take? (e.g. The request for land will first have to be investigated
    and agreed to by various technical departments within the council. Is the land available, is it developable
    in terms of geotech, availability of services, etc. – then it must be submitted to council for a resolution in
    principle, then given to legal for drafting of the actual agreement, and finally accepted by both parties, and
    then the board’s and the town manager and/or mayor’s signature/s must be obtained).

Next, the programmer needs to decide in consultation with the board, the PM and key stakeholders on a high-,
medium- or low-risk approach to how long administrative processes should take, and the degree of overlapping
that is prudent.

Programming techniques/tools
Programming tools vary from simple charts where activities are listed in sequence from top to bottom along
the vertical axis, and the time an activity takes and where it belongs in the sequence are depicted graphically
by lines or bars on the horizontal axis time-scale (bar chart or Gannt chart), to complex computerised network

Programming requires a good understanding of the development process, and how changes in the duration
and/or sequence of activities in the process impact on each other and affect the completion date.

The pre-tender project planning time-line
At the time the first cost estimates are done, much work still has to be done before the actual construction work
starts. All or most of the following processes and activities may still need to take place:
•   Acquire and secure the land (option periods, offer to purchase or land availability agreement, registration
    of transfer in deeds office) – anything from 2-6 months (during this time preliminary designs and feasibility
    studies can be done).
•   If required, township establishment or rezoning, or other formal town planning/legal procedure, including
    an Environmental Impact Assessment (EIA) to clear obstacles to development – anything from a minimum
    of 6 months for rezoning (more realistically 8-9 months), to 9-24 months for township establishment.
•   If the above is not required (as the land is already zoned for the intended purpose), then proceed to the
    next step, namely –
•   Architect prepares site development plan, followed by other drawings for municipal submission (2-4
•   Await municipal approval and permission to build, which can take anything from 2-4 months (during this
    time the professional team could proceed with preparation of technical and tender documentation, and call
    for tenders so that municipal approval and the go-ahead to the contractor more or less coincide).

                                                                         G U I D E L I N E S PROJECT FINANCIAL VIABILITY STUDIES

A typical time-line for pre-construction project planning where the land is
already proclaimed and correctly zoned, and requires no further formal
town planning procedures:
               Activity                                                      Time in months

A typical time-line for pre-construction project planning where the land is
already proclaimed, but requires rezoning:
           Activity                                                      Time in months
                          1(to 3?)      2   3   4       5        6       7       8       9-16    17    18        19        20    21   22
 Define project
 Identify land
 Acquire land
 Rezone land
 Market surveys
 Plan approval

The above are indications only. Real times will be affected by the degree to which the SHI is willing to take the
risks involved in overlapping some activities, the availability of money to fund land acquisition, rezoning costs,
professional fees for documentation, etc., and administrative delays in getting land availability agreements set
up, etc.

Realistically, the shortest time between project initiation and getting a builder on site is probably 12-16 months
for straightforward cases, and 20-24 months where complications such as rezoning are involved. These periods
will vary considerably according to individual circumstances and the degree of overlapping the SHI is willing
to risk (for instance initiating land acquisition before preliminary studies are complete, proceeding with town
planning procedures on risk before the property is transferred, preparing full tender documentation before plans
are approved, etc.)

Township establishment could take slightly longer than rezoning in simple cases (where a single piece of land
is owned by council), or could add anything from 12 to 24 months to the normal process in cases where, for
instance, a new estate has to be planned on previously unproclaimed land. This is because new land-use layouts
will have to be prepared and submitted to various government departments for input.

The critical element method for estimating construction periods
The most accurate way of estimating the construction period is to measure rough quantities of the critical
elements (bulk earthworks, basements, concrete and steel structures, etc.) and then draw up a bar chart or
critical path programme by calculating the duration of each critical activity according to its quantity and typical
production rates.

This would be far too time-consuming at the time of estimating, and a quicker method is required at this stage.
A simplified version of the critical element method is therefore probably the most appropriate estimating tool. It
is based on the observation that the concrete frame in the case of multi-storey buildings, and the walls, slabs
and roofs in the case of walk-ups are usually the main critical elements. The method is to first estimate the time
needed for the structure, and then to add time for start-up and finishing off.
