Preface
The objective of this work is to present to the engineering reader information about the
practical aspects of Engineering involvement within Oil & Energy Industrial facilities
promotion. These industries produce various types of gases in condensed form for the
transportation through the pipelines for supply to the real consumer or the end user and
also various petrochemical products as well as many bye products are produced. All
disciplinary budding working engineers in the industry & particularly in the execution
field shall be benefited by the information provided. The contents have been extracted
from the practical experience earned in the field.

A brief on the description of the terms used has been included. It has been noted that
experiences attained are usually not recorded on documents for the benefit of the
incoming young engineers to learn from the seniors‟ experience resulting adversely on
that these budding engineers depend solely on their individuals exclusive learning in the
field based on the university learning which is not virtually adequate for a fast progress
achievement. Therefore, to fulfill the requirement to extend the learned resources to the
incoming new engineers, this small work is presented to help those who intend to know
in advance about an overall perspective of building new facilities or extending the
existing one to further development.

The information has been given in text only. No photo or diagram could be incorporated
as under the obligations of the contracts such information should not be revealed for a
definite number of years from the contract commencement day to maintain the secrecy
conduct clause on various contracts. This work may not provide with the in-depth
specialized subjective knowledge but definitely, illumine with an idea how the
procedures move in the field which knowledge cannot be drawn from the university.

This book might prove beneficial for the candidates aspiring to become certified
professional engineers. Of course, the contents of the book are very boring but
practical. The contents vary in nature including the usual procedures of the EPC nature
of contracts involving in general types of Industrial jobs carried out in the industry. Also
included certain statements & reporting procedures as well as contract matters
generally adopted. It is uncommon among engineers to be used to reading this type of
work but practically, it is necessary. It is hoped that reader shall enjoy the work.

I am grateful to Cdr Eng A K Poothia, The Secretary & Director general of The
Institution of Engineers (India) for commending this work & extending most
useful advise for which attempts were made to incorporate to some extent.
Attempts shall continue to incorporate the readers’ suggestions as much as
practically feasible.

arrangements are worked for the curing solutions for such low heat generating cements
to effect thermal curing methods.

Cracking gas furnaces- this meant for the purpose of cracking gas from the refinery as
bye product for the transmission to the compressors for the production of ethane as well
as propane. These are tall heavy structures vertically oriented in group of vessels &
founded on a common base.

Other structures included wash water structures, auxiliary boilers within the processing
train. Also included various spheres to contain gases as well as tanks for storage.
Foundations for the tanks are generally constructed of RCC ring beams. Other
structures are provided with independent footings stripped using grade beams.

Seawater basin- A RCC open reservoir meant to collect water from sea through 2 # 84”
pipes, supply to the plant various trains requirement & after cooling the system dispose
water to be disposed from the industrial locations to the receiving basin & then to outfall
chamber. It is a huge voluminous open structure constructed of RCC base slabs
provided construction joints during construction, peripheral retaining walls up to 12 m
high not more than 9 m panel as well as covered pump house area & baffles. Such
structures must be water tight from all locations of the water storage portions duly tested
for water tightness using BS 8007 criteria. Concrete protection is applied for both below
ground as well as above ground surfaces.

Many other stationary as well as vibratory equipments are included for the processing
plants for which foundations are constructed accordingly either as footings bases or
combined footings. These horizontal or vertical vessels are erected on these bases
connected using anchor bolts & grouting done between the sitting steel plate & the top
of concrete. For vibratory equipment, epoxy grouting is applied while for stationary,
cementitious.

Sump chambers – These covered chambers are used for the collection of water from
various catchment areas & constructed of RCC underground structures duly tested for
water tightness using BS 8007 criteria. Concrete protection is applied for both below
ground as well as above ground surfaces.

Manholes, catch basins, rainwater ditches, etc are constructed using RCC.
Manholes are meant for the sewerage line oily manholes for oily discharge, catch
basins for rainwater. Generally, these units are in large numbers for any plant area
making it preferable to produce by pre casting on site for which all working details for
the yard are required to be issued to site.

various supports as well as anchoring requirement. Various types of supports are
designed for varying diameter of the pipes for the on ground or underground or
aboveground use.

FRP (Fiber Reinforced Plastic) Pipes
RTRP stands for reinforced thermosetting resin pipe, a composite material consisting of
a thermosetting polymer, a type of polyster reinforced with glass or other fibers that
provide strength & stiffness to a composite material. Different type of resins used for
manufacturing GRP, GRV & GRE pipes are Isophthalic resin, Vinylester resin & Epoxy
resin respectively that are selected according to the required properties like chemical
resistance, temperature resistance & mechanical properties. The resins provide thermal
& chemical properties such as glass transition temperature, resistance to heat, chemical
resistance etc. required for finished product. The properties of GRP pipes can be varied
by changing the ratio of raw materials as well as winding angle. These pipes consist of
three layers adherent to each having different characteristics in relation to functional
requirement.

Inner Liner – Veil (Glass), Resin: CSM (Glass), Resin
Structural wall - Roving (Glass), Resin
External liner- Veil (Glass), Resin

Inner Liner – Veil (Glass), Resin: CSM (Glass), Resin
Inner Liner one is chemical resistant being in direct contact with fluid & therefore,
responsible to resist chemical corrosion as well as permeability. The internal surface is
particularly smooth to reduce the fluid head losses & also opposes the growth of
minerals & algae. Lines has two monolithic sub layers. Inner in contact with fluid is
reinforced with glass veil with a resin content 90 %, outer reinforced with CSM glass
with resin content 70 % by weight. The standard liner thickness is about 0.5 to 1.5 mm.

Structural wall - Roving (Glass), Resin
Glass Reinforced layers guarantee the mechanical resistance of the whole pipe against
stresses due to internal & external pressure, external loads as well as thermal loads.
For GRP / GRV pipes, the layer is obtained by applying on the previous partly cured
liner continuous riving of glass wetted with resin under controlled tension. For GRE
pipes, the structural wall is wound directly on a wet liner. The layer can contain
aggregates like silica sand if allowed by specifications while thickness depends on
design conditions.

External liner- Veil (Glass), Resin
Topcoat or external liner is the outer layer of pipe consisting of pure resin. UV protectors
may be added if so required to protect the pipe from solar exposure. In case of severe
exposure condition like aggressive soils or very corrosive environment, the external liner
can be reinforced with a surfing veil or added with filters or pigments.

Fiberglass composites consist of glass fiber reinforcements, thermosetting resins &
additives designed & processed to meet specific functional performance criteria.
Amount, type & orientation of glass fibers in pipe provides mechanical strength. C
Glass, E glass & ECR / Advantex glass are used commonly depending on pipe
application. Various forms of glass reinforcements are surface veil, chopped strand mat
(CSM), chopped roving, filament roving & woven roving (WR).

Raw materials like catalyst, accelerators, inhibitors, aggregates & pigments are used
together with resin & glass reinforcements to achieve desired properties of fiber glass
product. Catalyst is an organic compound which when added to resin in presence of an
accelerator determines the polymerization reaction at ambient temperature. Acceletor is
a chemical compound used together with a catalyst to shorten the polymerization time.
Inhibitor is added to the resin to reduce reactivity at ambient temperature.
There are two manufacturing processes Dual helical filament winding process & the
other being Continuous winding process (Drostholm)

Pipe racks are used for the purpose of running the piping from one point to the other
over ground levels. These are generally steel structures founding on RCC footings but
RCC frames structures are also used. Several km of pipes are run on these racks
supported & anchored to the rack structures. These are fully accessible structures for
maintenance purpose. Open flooring is provided.

Heat tracing is applied on the piping carrying minus degree gas which may freeze
during flow & block pipes for the protection of which, the heat is continuously maintained
on the piping to keep the gas in the condensed form. Various loops are provided on the
piping routes for various purposes.

Pipe supports / sleepers are used for the purpose of carrying the pipes at near ground
levels. These are RCC units located at defined spacing. For direct support of the pipes,
steel structural supports are used remaining connected or touching pipe by shoes over
lengths at various spacing meant for the purpose of sliding also. For deciding the
locations of the supports & the anchorage, stress analysis is conducted that dictates the
spacing, dimensions & the pipe structural base design. For a pipe of dia not more than 4
m, not more than 12 m spacing is adopted. For other smaller dia pipes, the spacing
depends up on the standard length of the pipes. Pipes that need sliding movement at
the joints are provided such a base that allows the movement of the pipe in the direction
of its run. For that, PTFE (Poly Tetra Fluro Ethylene) bearings fixed on steel plates duly
designed to withstand imposed force are provided. Below the pipe support shoe steel
portion, a stainless steel plate is provided so that this plate slides over the PTFE pads.

Anchor sleepers, big sleepers, thrust blocks are used at various points depending on
the stress analysis requirement on the en-route pipeline. These are thick & voluminous
structures requiring thousand of cum of RCC for an individual sleeper connecting a
group of pipes. On the pipe loops various kinds of stresses from all directions are
imposed during operations or flows which are to be resisted by these sleepers. At the
change in directions of the pipe routes as well as at the Tee locations etc, big sleepers
or thrust blocks are provided to resist the resultant forces. These are constructed of
massive blocks of RCC.

Access platforms are constructed to access to an area above the pipe level for the
maintenance purpose. EOT cranes are installed for the maintenance as well as lifting &
placing the pipes & other items in the shops. These also meet the crossing over pipes
requirement. Proper ladders, handrails & open floorings are provided for the safe
access.

RCC box culverts are used for the cross over of the underground pipes below roads.
Pipes culverts are also used wherever required. For the accommodation of the spillage
tanks, bunding is carried out around to hold oil during spillage. Pipes are connected to

Reliability and availability, particularly system uptime are key project drivers. A
systems effectiveness model shall be developed for the complex comprising the base
case configuration of the offshore facilities and GTL (Gas to liquid) plant configuration
FEED for the project units so that the required overall system effectiveness of
335 stream days per annum is reached in a cost effective manner.

The offshore development concept is based on direct transportation of the
produced fluids and gas from the wells on platforms to shore without any offshore
process or treatment. From each platform, there shall be multiphase carbon-steel
trunk line to the common slug catcher. Chemical injection and regular pigging shall
be applied for corrosion as well as hydrate formation inhibition to the carbon steel lines.
The produced fluids are received into the slug catcher in the upstream onshore facilities.

Field and Plant Condensate Treating
In the Onshore Upstream facilities, Condensate and water / kinetic hydrate inhibitor
(KHI) & corrosion inhibitor ex the slug catcher are separated. Water is sent to a
dedicated effluent treatment which caters for the KHI and possible saline components.
Condensate is stabilised and treated (for sulphur removal / conversion) for export sales.
Wet feed gas ex the slug catcher is routed to gas treatment followed by NGL extraction
and fraction. The gas treating facilities remove sulphur components, water, CO2 and
mercury from the feed gas.
Treating of the ethane (ethane recovery and treating facilities shall be installed later)
and LPG products to further remove residual traces of sulphur, water and CO2. The
sulphur components so removed shall be converted to elemental sulphur for export as
liquid sulphur.

Onshore downstream: Synthesis

Activation & Regeneration - Water Distillation - Steam Methane Reformer - Hydrogen
Manufacturing - The ASU‟s main purpose shall be to produce oxygen for use in the
SGP as well as also produce HP Nitrogen for the CAR unit, LP Nitrogen and
compressed air for use as site utilities.

In the SGP syngas shall be produced from natural gas (NG) and oxygen by partial
oxidation. The SGP produces the majority of the syngas for subsequent conversion to a
synthetic heavy paraffin stream in the HPS. The SGP syngas requires treatment to
remove soot and undesirable by-products.
In the SMR hydrogen rich syngas shall be produced from NG and steam by a catalytic
reforming process. The SMR syngas has a higher H2 content than the SGP syngas and
is used to supplement the syngas feed going to the second stage of the HPS reactors.
The reaction in the HPS follows the Fischer-Tropsch chemistry and produces significant
quantities of process water as a by-product.
The WDU shall be used to strip hydrocarbons from the process water which be
subsequently sent to the effluent treatment plant for recovery.
The CAR Unit shall be used to regenerate the HPS reactor catalyst.

Technical Proposal
It is unavoidable in this age of tendering particularly on the Industrial projects of
international Quality Assurance nature, that the bids are submitted in two parts together
or separately depending upon the Client requirement. Technical bid is always a lead
submission package that is invited to fully assure whether or not, the bidder is capable
to execute & prosecute the project smoothly. In case the technical bid is rejected, there
shall be no need for the bidder propose commercial part of the bid.

Technical bid is a voluminous document containing complete details of the bidder‟s
intentions to carry out the project execution from the commencement to the completion
stage describing in details ways & methods for every part of the proposed project, how
these shall be handled & whether or not, bidder is adequately resourceful, technical
capable & scrutinizing all other aspects, bid is evaluated.

Technical bid should contain fully descriptive & completely integrated infrastructure of
the bidder in all respects about design & execution philosophies, execution plan,
machinery & man power proposal, alternative proposal if so necessary contemplated by
the bidder, full design criteria, materials proposed from the authentic source,
acceptability of Third Party Certification, deviation from the contract & its controls,
complete safety programme detailing & risk analysis, Hazard study, safety records,
safety plans proposed, evidence of past safety capability records, various well designed
forms to be employed for the whole duration of the project

It also requires descriptive proposals from the Quality Assurance & quality control
section providing all necessary formats & detailed methods of quality control
maintenance including Inspection & test plans, check lists & all quality documentation
procedures, method statements, proposed independent testing laboratory.

All procedures pertaining company documentations shall be included involving internal
documents matrix used & ensuring that documents traceability is smooth. Engineering
procedures including procurement shall also be included within this proposal giving
complete feed back on proposed designing system, software to be used, designer‟s
potential, complete requirement of the job related material, job temporary facilities to
accommodate the manpower etc

Since the Technical Proposal is based on the provided FEED documents by the client
or the client appointed FEED contractor, whatever contents of the Technical Proposal
be presented, should be based on the technical directives included within the FEED.
The base firm proposal should not at all deviate from the FEED requirement. The bidder
is required to endorse the Technical bid stating that the bid is completely based upon
the FEED meeting all requirements unconditionally. The content of certification should
be in accordance to the format provided.

There may be an alternative proposal in addition to the firm proposal which may satisfy
the requirement of FEED in addition to making cost & time saving to the client
according to the Value engineering consideration that the client could accept if within

the FEED. The Technical proposal is very comprehensive presentation content wise
giving all information of the contract execution wise from the design to the performance
& handover stage. No room is allowed for any commercial reflection within this
submission. In fact the consistency & capacity of the bidder is measured from this
submission.

Many rounds of the submission are conducted to scrutinize the submission of all
chapters. These chapters should be simple in the style to allow full communication of
the bidder to the engineer/client to facilitate an easy understanding of the proposed
execution. All sources of the materials, equipment & all other items to be used for the
permanent inclusions on the project should be enlisted in a scheduled manner in line
with the FEED requirement. Proposed work schedule to meet the defined milestones
should be explicitly described convincing every one concerned that the bidder approach
is feasible in practical terms.

All workforce & staffing levels as well as management to supervise & direct the project
should be clearly defined including the CVs of all key levels. These levels should meet
the defined criteria according to the FEED as well as professional competencies.
Design procedures should be clearly defined in a precise manner including giving all
designation of Information Technology to be utilized for the project. In brief all other
proposals for the proposed facilities for the temporary works as well as for the
permanent works should be included explicitly. It is a long format but should be precise
& to the point. The client is never interested in a voluminous documentation for show
purpose but a precise content giving all true & relevant information is always welcome.
It should be remembered that all these proposal documents shall be required for the
actual demonstration proving the consistency as well as competency of the proposal. It
is better not to propose something which is not practiced by the bidder, otherwise
demonstration could detract the bidder. Many cases have been noticed when after the
proposal, comments are received from the engineer asking for many clarifications which
are difficult to reply positively. Be straightforward for the submission.

Quality assurance as well as Execution statements constitute very important &
significant role for providing value to the technical bid for which due time & devotion
must be given by the bidder. The experts should be engaged for the detailed inclusions
of the necessary information inclusion within the documents for the client consideration.
Untoward information should preferably be avoided. Once the bidder is short listed by
the engineer or client by the establishment of the bid competency, the call for the
commercial presentation should be given or there is no use in case the bid fails to meet
the FEED requirement.

Contract award
Within this procedure, the short listed parties shall be invited to tender for the EPIC bid
who in turn calculate the demanded facility EPIC or EPC lump sum firm price for the
whole or part of the job in defined fixed time based on the FEED documents, provided
which submission shall be Technical in one part & Commercial on the other. Sufficiency
of the Technical bid shall decide whether or not, the commercial bid should be
considered.

After having the Technical bid qualified by the bidder, the qualified bidders shall be
notified about the opening time schedule of the commercial bids. The EPIC contract

Industrial Safety Briefs
Safety, Health & Environment-
First & foremost is the safety for any project. Slogan SAFETY FIRST is very common
among the safety promoting projects. Without safety no work is allowed. Safety is the
responsibility of every one. Every person working on the project must use personnel
protective equipment PPE & all necessary special precautions must be taken whenever
directed by the safety official responsible for the project. All activities must be conducted
in a safe manner to the best possible minimum cost incurred on safety. In case no
proper arrangements are made to keep safety intact, the execution of the activity should
be suspended. On important works, safety team must be present & support the
construction team for smooth safety management. Site engineers should abide by the

instruction & direction given by the safety personnel. Proper care must be taken during
deep excavation works as well as overhead works.

Safety plans-
Discipline activity based safety plans should be prepared in conjunction with
construction in-charge, approved & issued by the safety department for the guidance of
the construction personnel.

Training- Various classes of training are necessary to be imparted to the site personnel
for onsite implementation.
Induction- Immediate on the joining, all personnel should be given safety induction
course duly recorded on proper register for the training. The course must include all
precautionary instructions required on the site generally to be prosecuted onsite.
House keeping- Training should be given to all personnel to keep the working & other
areas tidy during & on the end of the day. Tools should be properly kept on site.
Material should not lie here & there. Working environment should be felt comfortable by
all concerned personnel.
Supervising safety
Every supervisor should be trained for the understanding of managing safe supervision
over the site operations. How to handle the ground works & how to handle the overhead
works. How to make the workers understand all procedures of safe handling the
operations so as no operation should effect the workers‟s health badly causing no
overstress physically.

Heat stroke
On constriction sites particularly in hot & arid regions, the effects of heatstroke are
imminent to workers. They should be taught the methods of how to prevent such
incidents by gradually inducting the worker to the hot working conditions & over timings
adjustments.

Fire watch
Every workers should be clearly taught the ways of possible fire incident & if occurs,
how to handle to extinguish.

Toolbox talks
In general, prior to begin any activity, tool box talk should be given to the group working
on the activity involving any or all calling. How minor or major injury may occur during
carelessly using the tools & how to act if injured.

Liquid consumption & food
Every worker should consume water or available drinks after a period of work to protect
one from the adverse effect of dehydration & should be allowed the intermittent rest
pauses.

Dust prevention

Dust accumulation causes environment degradation & affects working on site. During
such inclement weather conditions, ample means of water should be available to spread
on site so that the dust does not lift into air.

Sanitary
Adequate arrangements must be made on site for the workers & staff to use sanitary
facilities throughout the currency of the project to maintain the working area healthy &
hygienic.

Regular courses-
In groups workers should be given feed back on the site safety as well as gas inhale
prevention, during fire how & where to assemble, how the fire alarm works etc. How to
construct for temporary platforms at high levels to be used for various purposes to meet
the site instant requirement.

Special courses-
How to take precaution to avoid electric shocks or some other hazard.
Incentive should be given to the leading workers who keep proper safety as well as
check & advise coworkers & colleagues to take due measures. Accessibility to site
horizontally as well as vertically should be explicitly explained to every one. Positioning
of the ladders in the trenches, which location shall not be more than 8 m. Provision of
the platform guardrail of suitable height. For example use of wooden or Aluminum
ladder in excavation areas or to the higher working areas. Platform construction,
supports, toe board etc. Fire extinguishers use. First aids use. How to access
emergency phones for hospitals.

Site Safety Walks-
Whenever necessary, site walk should be conducted by the safety engineer with the site
in-charge to pin point the deficiency on safety & on site correction applied.

Tool Box Talks-
Every skilled worker, semi skilled or unskilled should know about proper use of the tools
& maintenance of these. They should be explained about all types of dangers if the
tools are not properly used during work

Risks Analysis-
Keeping in view all types of operations on site, what risk are imminent, should be
studied by the safety engineer & in cooperation with the construction people & expected
causes of risk & their relevant solutions be explained to the team for implementation on
site as well as properly documented.
Safety of heavy equipment-
Crane operation, shovel operation, concrete pump operation or any other equipment
operation requires a complete safe operation system. How to operate these machines
safely on site. License of operators as well as banks man instruction manual. Third
Party Certification for the crane particularly. Only licensed operator should be allowed to
carry out the lifting operations.

Programmes-
Regular & frequently, safety programmes should be conducted on site from every
aspects to make all aware of overall safety to avoid accidents
Practical training should be conducted for the equipment operators to let them
understand the effects of not conforming to the safety practice.
Inspections-

Safety engineer should inspect working areas frequently to examine that the
arrangements adopted on site for the running operation meet the necessary criteria of
the safety rules & if observed certain deficiency, the site engineer should be intimated
for the corrective measures.

Awards-
To motivate the workers on site to take due safety measures during working hours &
thereafter as well, awarding system should be adopted for the workers who work on full
safety on site.

Audits-
Corporate safety team should check casually & as programmed, the safety records
physically on site & due observation circulated along with the proposed corrective
measures.
A healthy worker on site works many times better than a sick & unsafe worker. It is
better to spend reasonable amount on safety rather than spending on loss of work
causing inefficiency on site.

SAFOP-Safe Operation- It is the key to the success of the project in all respects.
SAFAN- Safety Analysis- Prior to an application of the safety, complete analysis is a
must to know & select the best safety methods
SYSOP- System Security & Operability Analysis-It is very significant from safety
engineering viewpoint. Until complete problems are listed, applicable procedures may
not be known. Systems generally involve safety against fire, gas explosion & electric
default. Therefore, these import application of all precautionary measures selection of
which depend on the detailed requirement as obtained from the risk analysis & details of
equipment operations.
OPTAN- Operator task Analysis-Control & field Operator-This part also involves
detailed study as well as precise applications. No slackening should be allowed.
Attempts should be made to take due measure to prevent accident in hot work as well
as cold work areas & also in restricted & confined entry areas. Permit to Work PTW
must be applied to work in such areas of the facility.

personnel. As far as possible, all essential design details shall be included for the
exhibition purposes. These models should be fabricated in different modes like
drawings that means bird‟s eye view, sections within that & many different views for
clarity.

Engineering Design-
For EPIC or EPC, the design part is a major contribution to the successful execution of
the contract. Design of the whole project components / constituents are demanded to be
produced one by one meeting the timely requirement to the project plan. The designing
team should understand explicitly the contract philosophy & the FEED documents prior
to commencing the design work. Complete Project Design Systems should be produced
based on the FEED & the best possible design alternatives for a minimum cost. The
project target to be achieved should be clearly understood.

First & the foremost significant part of the design process is the selection of the
processing machine / equipment to be installed as a part of the processing trains, which
machines may include horizontal & vertical vessels, vibratory & rotating machines,
pumps, oil tanks, gas tanks, all related control instruments, electrical installations, gas
installations, safety installations, all equipment necessary for the complete facility safety
& controls, fire fighting controls.

Equipment selections may take time & delay the whole facility construction therefore,
prompt decisions should be made. It should be kept in view that the foundation designs
pertaining the equipment depend on the parameters of the equipment. Initial
foundations designs may be amended based on the final selection for the inclusion of
the equipment. Related drawings about equipment based on the feed back available
from the FEED should be schematically produced for the considerations of the structural
design engineers for initial use which shall vary may be to an extent of 10 to 15 %
during final stage of the designs issue. All designs should be correlated in sequence so
as not to miss any part of ant machine in the train. All designs of the equipment to be
included other than the trains should also be similarly produced in a timely manner.

All constituent parts or elements of the project regarding all engineering disciplines
should be enlisted & a programme charted out to show the start & issue dates
pertaining various design drawings for review & approval by the Clients. The discipline
wise engineering design work should then be entrusted to the charge of a disciplinary
design engineer. All design discipline engineers should report to the engineering project
engineer or Manager as the case may be.

Engineering Detailing-
After having received the preliminary drawings approved by the Client, the design team
should concentrate to produce all necessary drawings, which should then be submitted
along with the building permit application to the relevant municipality if so required.

The design engineers should also commence with the detailing of all structural &
architectural elements of the included parts of the project. All other disciplinary details
should also be taken up simultaneously. This part always consumes much time &
therefore adequate staffing should be allowed for details production.

These detailing should include sections, various details on plans, details of all elements
necessary for execution or for the transmission of the information to equip the shop floor
drawing engineers for working drawing production. There shall definitely hundreds of
such details discipline wise. Crosscheck must be applied to all these details prior to
giving a final approval. Working out of the details shall require multiple considerations of
thought to be given for the end results of the design so as to make it convenient for the
ease of construction execution with the application of minimum efforts with keeping cost
to a minimum as far as practically feasible.

Concept of the detailing is a cumbersome job requiring competent skill on the part of the
design engineer who coordinates mentally all possible operations related to the
designing & construction by these details. The details dictate on many outcome on site
& help the construction engineers a lot if well thought of in advance. Sometimes, the
good-looking details are difficult for execution.

Details should be as easy as possible to save the procurement as well as execution
duration to minimize the cost. It is suggestible that as far as practicable, standard items
should be included in the designs for easy procurement. Also these items are well
known to the experience supervisors involved with the construction operations. Typical
details production shall give good results for the production purpose. Unnecessary
details should be avoided. Details should be explicit to make the engineering

coordination easy for easy references. It has been experience that multiplicity of
documents coordination creates unnecessary difficulties for the execution team while
clashes & absence of necessary details as well as so many other factors result in the
raising of engineering & site technical queries ETQ & STQ respectively. These queries
further augment the recording & execution complicity. Generally it happens due to the
involvement of many hands as well as change of heads on the same job. Some
competent engineer should concentrate on one activity to reach it to the conclusive
decision so as to be finally sent to drafting section.

Also cross-references on the drawings should be properly reflected for there are
chances of missing these.
It is also suggested that what details are required should be planned in advance of
commencing the detailing work in the form of a working schedule to keep a control on
the quantity of detailing work.

Design Schedules-
Major items schedules respecting all disciplines should also be included within the
detailed designs to guide the construction team for placing various Material Take Off
MTO after due verification. After producing all necessary detailed documents, a guiding
bill of quantity BOQ should be prepared for the whole project to assist the construction
team to place various order after due verification of the quantities as well as the
applicable specifications & codes.
No limit governs the quantification of the production of schedules for it depends on the
discipline as well as the size of the project. There may be hundreds of such schedules
for some project while some only a few. But quality schedules help the placement of the
procurement orders.

Scheduling is no easy job. It requires complete know how of item under consideration. It
also requires complete coordination within all relevant drawings & technical documents
to reach final take off the quantities & the applicability of the specifications & drawings
as well as specialist specifications produced by the manufacturers. Scheduler has to go
through all these procedures immersing fully for all related items.

Submissions-
All aforesaid project documents which may include all design drawings, detailed
drawings, schedules, project specifications designed by the specialist engineers should
be registered properly according to the agreed system of documentation & thereafter be
submitted under cover of a transmission sheet to the approving authority engineer for
technical approval in the form of IFC Issue for Construction. It is not essential that the
documents should be approved in first submission. Comments received back from the
engineer should be incorporated on the revised documents & resubmitted keeping the
process continued until the documents are approved for construction. After the approval
for construction status, the document should be copied in required numbers as agreed
within the documentation procedures duly sealed on the document & circulated to the
concerned parties. Copies should also be transmitted to the engineer for site use.

Shop drawings
All details as explained above cannot be practically produced within these documents.

production operations, it shall be essential to produce some more documents to be
used by the shop floor engineer. These documents shall be worked out from the
coordination among all such gathered information solving probable clashes & giving a
final shape for production or execution on site. These documents should also be passed
through the approval procedures & IFC document should be issued to site for
construction. There shall be hundreds & may be thousands such documents necessary
to be produced from time to time of site requirement. These can be entitled shop
drawings.

Working drawings-
Even after the availability of all approved documents, there shall be required some more
drawings to be used by the supervisors on site as well as in the workshop. These
drawings should support with further details of the sequence of works in the form of real
fabrication & execution at shop floor or on site. These drawings should be well drawn
clearly so that supervisors do not require further assistance to get the job done without
further details. These drawings should also be approved but all drawings do not require
approval. In some case based on the contract drawings & shop drawings further details
are worked out which are consistent with approved drawings, may be used directly
virtually off record.
Otherwise these drawings should also be approved by the engineer in which case
proper documentation is necessary followed by the issuing procedures as explained
earlier.

Technical Queries-
A technical query is raised when some discrepancy is discovered pertaining any design
item not correlating or corresponding between architectural & structural or any other
discipline drawing details. For the resolution of the correct detail, discrepancies are
raised in the form of a technical questions format giving full details regarding the
discrepancy & if possible, a solution be proposed or clarification sought or
understanding for confirmation made. This document is originated by the relevant
engineer, checked by the technical or engineering section & authorized by the site
management for transmission to the engineer for response. Engineer scrutinizes the
questions & writes back the answers for execution on site & recorded as red line mark
up.
There may be engineering queries ETQ or site technical queries STQ or SC site
clarification depending on the mode of the format adopted on the project.
ETQ is generally used by the Engineering team only whilst the STQ is used for the site
execution purpose.

Site works queries-
During carrying out works on site, dictated by the site conditions & to comply with the
specifications & design criteria, it usually happens that suitable adjustments have to be
made to the design details on the safer consideration. Such situation requires an
agreement between the Contractor & the engineer on site, which should be recorded on
the STQ for confirmation.

Proposals for technical resolutions-
Other than aforesaid queries, there shall be many instances when alternative detailed
proposal are to be worked out for site requirement to meet the design criteria &

sketches as working drawing as convenient. All virtual clashes on site due to
unforeseen conditions may be resolved on site & recorded as technical resolution in the
same manner.

Documentation appraisals-
At time of the contract execution as well as during the whole currency of the contract,
the Contractor shall from time to time receive thousands of documents in the form of
contract documents, post contract documents etc which should be appraised properly &
competently. All such documents should be registered in such a way that traceability
functions efficiently without wasting time of the engineers unnecessarily. The document
controller should have on his tips on the database any required document located
immediately. Arrangements should be such that documents for a particular element on
the job should be proficiently filtered out for better control. Project in-charge should
ensure that all required documents according to the register as well as fulfilling practical
needs of the project for construction have been issued by the designers.

Construction ability checks-
Issued / approved for construction documents pertaining all disciplines must be checked
sequence wise as well as discipline wise to make sure that these contain well-
coordinated information necessary for the 100 % construction of the relevant portion or
element. Project engineer should immediately notify any missing information to be
provided proficiently. Any clashes observed should be recorded any ETQ or RTQ raised
for a possible resolution without any delay to the execution. The approval about the
queries procedure should be perused personally in some urgent cases & the resolution
communicated to the supervisor concerned for on site implementation prior to the
mistaken work is carried out.

Inference of technical documents-
Inference of the technical documents is no easier an activity. Only a competent project
engineer or an experienced discipline engineer should be entrusted the job to explore
any missing information as well as to know whether or not the issued documents are
giving adequate information for the purpose of full construction or yet, the technical
queries are necessary to be raised. This activity requires total concentration to study the
contents of the design & their coordination & mutual interfaces. It depends on the
volume of the documents what duration is required for complete understanding of the
technicalities involved on the design. Study & review should not be confined to design
drawings only but detailed specifications should also be included so that complete
project requirement is properly integrated for physical execution.

Engineering meetings
Meetings for the engineering discipline form extremely significant portion of the contract.
Actually this activity commences at the tender negotiation time when technical proposal
is submitted. Hundreds of clarification questions are raised by the Client on the contents
of technicalities offered by the Contractor as well as those at pre bid stage as replied by
the Client based on the Contractor queries. For a collection of important queries,
meeting is conducted to resolve the issues in hand directly between the two parties.
During contract stage, when the design is submitted meetings are conducted for every
discipline for a satisfactory response on the design questions, clarifications & software
related issues or formal presentation of PDS project document system. During this
stage, meetings shall be very long but impart efficiency for the decision-making & save
time for the approvals.

During construction stage, regularly programmed meetings are conducted for the
engineering difficulties or other matter related therewith which require urgent attention.
These meetings more or less form part of the regular progress meetings until lot of
queries have been accumulated necessitating separate meeting. Day to day meetings
are conducted on site between the area engineers of two parties to resolve the matters
subject to the approval of the field engineering manager of the Client.

Engineering meetings cannot be confined to the aforesaid instances but according to
the job requirement, these have to be conducted at any level of supervision to expedite
the site works progress.
These meetings also involve the contribution from the quality assurance & control
engineering section on site for urgent decisions & acceptable to the construction
department.

Construction Method statements
During the construction phases, activity wise construction method statements are
required to be issued to the supervisors on site to adhere to the statements for the
smooth carrying out of the activity concerned.

These statements should be approved by the Client prior to the commencement of the
relevant activity. Method statement should be prepared by the project or discipline
engineer or quality engineer or office engineer depending on the availability on site. This
documents should contain full information about the activity under consideration giving
how the sequence & technicalities shall be carried out & how the inspection should be
conducted based on the requirement of the Inspection & Test Plans & quality check list
as well as conduction of the necessary testing & laboratory involvement from time to
time.

All disciplines require method statement. These should therefore, be prepared in
advance, checked & approved by the site manager for further transmission to the Client
for the final approval as IFC or AFC & circulated to the site as a document.

No limit governs method statements numbers. Agreement has to be made between the
Client & the Contractor on the requirement.
For the reference to the reader, a number of method statements have been appended
only for knowledge exchange. These are based on the practical experience & are used
on projects. Please use them for guidance only & create your own statements for
particular requirement. But basics of the methods writing can be advised herein. Just
think of what is the solution of particular construction operation.
Contemplate on what the involved minor activities are. What are the sequences &
materials to be used for temporary as well as permanent inclusions what are the other
requirement for the accomplishment of the operation from the inception of the activity to
the final outcome. After having considered all these, make a sequence thinking that you
are available on works & carrying out the activity. How the activity should be sequenced
one after the other & write the statement lines & then recompile to a comprehensive
statement.

There shall be a long list of method statement or procedures from different engineering
disciplines.

For example site preparation, camp construction, temporary facilities establishments,
earthworks, excavations, blinding concrete, formworks, reinforcement fabrication,
reinforcement assembly or placement, concreting, finishes activities, complete HVAC
system, electrical system, loss prevention system, specialist gas fire suppression
system, aluminum works, cladding works, structural steel erection at low as well as high
levels, road works, paving, piping both below & above ground, pre-commissioning,
commissioning, performance, maintenance, quality testing & many more.

It is not practically possible to produce all methods in one go but quiet in advance of the
relevant activity allowing time for approval; the statement should be prepared &
submitted for approval. The basics of the activity should be conferred with the relevant
supervisors & quality personnel & then finalized to the specification & design
requirement. The document should form an integrated approach for the job as
professional.


---------------------------------------
Chapter 4
Construction & Controls-
Construction & controls are very interrelated sections for successful completion of any
project. Design may be over safe or optimum but real construction involves actual
expenses, contract time & reputation. It should be the motto of any organization to apply
good controls on the project to keep on line with the programme or planning an actual
part of controls. Control includes, progress, cost, time, budget, quality assurance &
engineering & safety.
These are all integrated divisions, which should move in unison to achieve project
target. A well-designed project could be jeopardized during construction phase from
budget viewpoint should it not be given due controls application properly.

Schedules- Programming
Programming schedules indicating by GNAT bars or by CPM or PERT various graphical
representations respecting the overall & detailed plans for the time, activities,
milestones, manpower requirement, machinery requirement, cost flow & all other
requirement & running reviews of all these during the whole currency of the project from
real progress, lost time recoveries as well as look ahead projections. These documents
are produced involving all sections working for the project & reports are inter considered
by all departments.

Planning engineers or the project control engineers work for such activities dedicated on
the project & report from day to day & time to time basis. The planning activities
commence from the day of commencement to the final completion & documents are
produced from level 1 to may be level 5 depending on the project or the contract
specification requirement. Generally primavera or MS project software are used for the
professional documentation for planning purpose.

During tender stage also programming documentation giving complete details &
milestones, manpower, machines, cash flow etc are given for the inclusion with the
Technical Proposal, which is considered as one of the competencies of the proposal. In

case the details do not give full information about the proposed methods of execution
for which it forms a part, the proposal may be liable for rejection.

Mobilization-
The very first step to get into the stage of physical establishment for construction. The
site is taken over & all transfer stations are established using available satellite records.
Surveying department commences its works for the establishment objectives. Approvals
are obtained from the authorities concerned & from the engineer or Client.

Applications are made for the record drawings from the statutory services authorities if
so required. Applications are also made to the operating authorities for the issue of all
record drawings if so required for the permits. Permit to work PTW is required prior to
the commencement of any excavation in hot & cold work areas. No excavation is
allowed in projects until these permits are obtained. For the application of the work to
start permit, documentation is carried out giving details about the applied work, official
award letter, availability of the safety officers, full time supervisor, method statement etc
& then application is considered for sanction.

Fencing is erected & the establishment of the temporary camp & offices is effected
according to the engineer approved plans & method statement.
All arrangements for the accommodation for the personnel, sanitary facilities, water
supply for drinking as well as for washing purpose, electrical & air conditioning, fire
fighting, access to the camp, security, messing, sewage treatment plant, leisure areas,
common rooms, sports courts, parking, swimming pool, local shops, etc as required by
the contract & the temporary facilities that Contractor or the engineer deem necessary
should be provided.

Similarly, site offices establishment should also be constructed according to the site
establishment approved plans & Permit to Work obtained before commencing for the
site establishment offices. All provisions of the utilities should be made according to the
contract, engineer & Contractor requirement.

The site offices should start functioning on or before the appointed date according to
programme of mobilization. It should be kept in view that some agreed percentage of
payment should be released when the mobilization is completed & work can be
commenced with.

Mobilization also includes deployment of required manpower, machinery & the
supervisory, construction, safety, planning & engineering as well as administration staff
without any loss of time. This deployment shall accelerate the procedure on the
commencement of job in the beginning & time may be gained to keep in line with the
programmes.

Smart & efficient project managers & engineers understand this aspect very well & keep
very proficient at this stage as additional efforts are required to commence with the
project. Running project may not be that difficult to push but starting & streamlining all
departments operations demand efficiency & hard work.

Site offices require full fledged modern computerized facilities for fast interaction &
communication, intranet, internet, telecommunication, conferencing, sanitary, water

supply, drinking water dispensers, refreshments, electrical supply, standby generator,
heat, ventilation & air conditioning, first aid, ambulance, doctor for immediate attention
with nurse, assistants & a well established site clinic.

Site offices require full fledged stores, warehousing, mechanical & auto maintenance &
repair workshops, vehicular & equipment parking areas, labour temporary shelters for
lunch & tea etc as well as for rest pauses necessary under safety management for the
prevention of heat stroke & environment attack during hot working hours.

Materials-
Without materials no project can be completed in time. This is the only item that may
delay the completion of the project due to possible non-delivery in time. Material
constitutes more than 60 t0 70 % budget for the contract & every prudent Contractor
should intend to make as much saving as is possible out from this element of
expenditure simultaneously keeping in line with the quality assurance & control
procedures.

Every purchase department manager & the owner of company tries their best to procure
acceptable material within reasonable & minimum cost, making trial & again from a
number of interested vendors both before & after the award of a contract. There may be
some delay to decide from which vendor or supplier the materials are to be procured.
This is also expected in a similar fashion from the prospective sub Contractors.

But the relevant purchase managers should not endeavor to spend unnecessary
redundant time on this activity but make a decision in time to get to the site materials in
planned time including all FAT as well as SAT & performance tests.

Material approvals is a tedious & time consuming exercise which must be given due
consideration & optimum time management for a possible successful completion of the
contract. It has to be remembered that missing the approval, no purchase order can be
released by the procurement manager or project engineer/manager. It should also be
taken note of that there are hundreds of permanent inclusion materials respecting which
approvals are to be obtained. Every submission required full manufacturer‟s information,
engineers specifications as well as conventional practice demand & updated standards
& these should also be covered within budget cost other wise escalation shall take
place should delay is allowed resulting in the delay on completion leading to imposition
of liquidated damages on the contract.

Actually it is suggested that major homework should have been carried out at the
tendering time itself to avoid such delays, of course market may fluctuate but there shall
remain room for negotiations with the vendors or suppliers.

Manpower- Workforce
Significant is this element in the absence of which nothing is feasible. Difficulty is to be
faced when well-trained workforce is not available in time from the expected source.
Contractor shall try to deploy manpower costing within the job budget. There shall be so
many problems for deploying them & providing demanded facilities on the contract.
Human resources department should be efficient to deal with this matter so that
particular delay is avoided due to non-availability of the required planned manpower.

Workforce shall be time wise required respecting all disciplines & be kept on mobilizing
in & demobilizing according to project requirement. Similarly staff shall also be
mobilized & demobilized according to contract requirement. On considerable big size
projects, mobilization & demobilization programmes are prepared & approved by the
engineer or the Client to ascertain that the job commence in time & after the
demobilization, the progress is not effected adversely. In fact only after the approval
from the Client is obtained, any demobilization can be effected though the approval
shall not be withheld unreasonably. Control of manpower constitutes in itself a separate
mini discipline involving complete procedures from making requirement, forming
recruitment strategy, approving the strategy, using agencies, & then interviews, short
listing of selections & appointment on contract followed by mobilization to the job site.
This is a long process, which must be preplanned to avoid any conflict with the site
requirement.

Equipment-
Equipment necessary for the inclusion on the project permanently requires considerable
input from the Authorization, FEED stages to the performance stage. Technology
decision for the project dictates the model & types of the equipment to be installed for
the facility. Elaborate & descriptive detailing is extremely necessary during designing,
approval & procurement stages. The equipment installed must satisfy the design
requirement failing which the facility shall be jeopardized of performance giving any
possible halt to the processing & the Client or the operation authority shall make the
designer or EPIC Contractor liable to compensate all damages incurred to it by the
faulty commissioned equipment.

Equipment are too expensive requiring making competent decisions for the inclusion as
well as for the election of the vendor.
Decision pertaining the model dictates the foundation designs. This need should also be
kept in view while working on the designs to avoid delay on account of providing input to
the civil design team.

Frequent amendments/modifications have been experienced on the major projects
during the day of concreting or one or two days before. This type of bad practice should
preferably be avoided. If possible, certain decisions could be taken at the FEED stage &
the EPIC Contractor be directed to comply with the vendor of the equipment based on
novation of the item.

Procurement-
Procurement means to supply to the site all materials & equipment & the process
commences from the requirement scheduling, vendor selection, quotation invitations,
short listing quotations, specification matches, financial viability, approvability,
warranties applications & then the final decisions based on the quotation that fits within
the budget & items be the best for the optimum performance according to the
requirement of the contract.

Every company has established its own procedures meeting the guidelines of the
international quality procedures ISO 9001 according to which full corporate
management is involved for the procurement management practically effected by the
procurement manager or engineer of the corporate part of the company management.
This department involves itself for the complete operations front the estimations of the

items quantities through the delivery to site & taking up the issues to the insurances in
case of transportation damage.

During tender stage itself, the expected items are invited for quotations for specialized &
important disciplines with negotiations done. Later on subject to the condition that the
work is awarded to the tender, further procedure continues & final & confirmed
quantities are worked out based on the engineer‟s approval of the proposed material or
the machine which is separately applied prior to the placement of the procurement
order. This is very time consuming process as submission, comments, rejection,
incorporation of the comments, re approval etc all are involved. The process involved
initially complete package submission meeting defined documentation procedures. A
competent & experienced engineer should be involved to carry out all these procedures
for technicalities are to be resolved during the whole exercise. Study pertaining each &
every requirement should be conducted by the relevant disciplinary engineer &
quotations accordingly invited. Based on the quotations, & financial factors, further
scrutiny of the quotations regarding conformance to the specification & the project
design criteria are done. Then a comparative statement is prepared giving full technical
as well as financial with feasibility of timely manufacture & delivery & financial matters
such as demand of the letter of credits or other financial support etc. All are reflected to
be examined by the management for making a decision promptly.

Once the decision is made in favour of one of the suppliers, further submission
procedures should be started to obtain engineer & Client approval since procurement
order cannot be placed without the Client or the engineer‟s approval.

After having obtained engineer‟s approval, the requirement is processed for a
procurement order by the management & all accounting procedures effected & delivery
schedule confirmed. That schedule should also be agreed by the engineer & adherence
to the agreed dates have to be adhered until unforeseen circumstances irrelevant to the
general circumstances play any role.

The delivery should be made smoothly all in good condition to the site & the site
manager should arrange complete examination by his team as well as approval of the
delivery by the engineer concerned so that the delivered material or the equipment is
including for the part percentage payment as agreed on the planning schedule.

Physical Construction-Contract management
Construction Project Management
Physical construction
After having the mobilization been completed, time comes for the commencement of the
permanent works for which the actual contract is meant for. It is definite that the civil
construction takes the lead generally on all the projects. This requires the availability of
all the approved for construction drawings circulated under control to the relevant
supervisors/engineers for the purpose to correctly prosecute the works according to the
contract requirement. Sooner the commencement, better the prospective to save the
time and money.

Every site manager or the project manager should endeavour his plans with the support
of the schedule engineer to keep at least in line with the approved programme if not
advanced. For this attainment, all necessary resources availability should be properly

coordinated. For EPIC case all design matters should also be properly coordinated to
keep in line to facilitate the easy construction. There may be a case when due to some
unavoidable circumstances, some portion of the contract cannot be prosecuted, the
project manager should immediately find an alternative portion to replace the
prosecution so as to keep an equivalent proportion of the progress intact. Civil
engineering part of the contract is not that easy for it requires basic works on site
involving trades persons & semi & unskilled workforce along with the materials in site.
Relevant engineers supporting on site should be well experienced & proactive to take
up the responsibility for the results orientation. A well coordinated approach is
necessary for there could be many instances requiring on site decision to resolve
technicalities that must be immediately effected meeting the requirement & properly
recorded as a part of field office engineering.

Physical construction requires a concentrated as well as diverse attention of the quality
assurance & control section or department on site. There should be no delay on this
account for the approvals & constant inspection attendance should be ensured
whenever necessary on a fast track project.

Every activity is inspected according to the Inspection & Test Plans based on a checklist
& percentage witness etc. Hold points should be released when the activity is on that
status. Most of the jobs are based on the concreting constituting very important element
of the contract & quality assurance should take proper attention for this onsite operation.
It should also be noted that whilst the civil engineering activities are prosecuted on site,
simultaneously, on a foreign station or in a foreign land, other discipline activities for
example production of equipment, the pre engineered parts of the structure & other
procurable items might be under manufacture demanding factory testing according to
the procedures approved. QA & QC should take into consideration proper inspection
attendance there as well under the supervision or surveillance or witness of the
engineer or the experts for the acceptance of the factory products as level I &
completion of the parts in factory or manufacturing place as level II inspection prior to
the equipment is shipped to the site location. It is no use should the equipment be
rejected after delivery on site.

Contract management
It is very wide term on the Industrial contracts. Basically it is the main contract that
requires well-established professional management but also covers various sub
contracts as well as services contracts. Requirement of complete knowledge of the
relevant laws, procedures & coordination correspondence are extremely significant for
the performance of Contract management. It is not just one discipline, but from the
beginning of the project & until post completion, Contract management shall be required
to be applied & represented on site as well as in home office for the resolutions of many
complexities. This term also covers a wide part of the documentations to be prepared
for forming future arbitration basis as well as proceeding.

It may involve costing effects, claims, extras, extension of time claims, additional
contractual obligations, contractual correspondences & many more legal affairs
requiring resolutions on the contract or the sub contracts as well as services part of the
low tier vendors. This term is very complex as its proper implementation necessitates
the contracts manager to know & properly understand the engineering, construction, co-
ordinations & relevant contractual & general laws applications on the contracts.

Construction project management.
Project site manager or the construction manager or if project engineer be authorized
for this responsibility, got very leading & significant obligation to dispose off on a daily &
hourly basis. What is going on site is direct responsibility for accountability. Daily,
weekly, monthly programmes as well as all discipline coordination is a must for the
speeding of the operations. Then also comes the duty to arrange & coordinate the
materials as well as the other resources to be utilized on the project. Attendance on the
engineering, construction, safety & other meeting is a must. The outcome of the
construction depends on the efforts of the construction team. Coordination with all team
members as well as the team members of the engineer Client is a must. Co-ordinations
with all sections of the site teams & home office teams as well as procurement are very
significant. Authorizations of the letters & correspondences produced by the contract as
well as other departments for the project is also one of the duties. Reporting all
functions to the Client as well as to the home office & resolutions of all possible
solutions is also one of the responsibilities. Authority has been invested with him to
allow resources promotions & imparting training for the personnel of all categories as on
job training. Job requires very dynamic & passionate person who commands all & gets
respect from all sections & keeps good working relations with the Client as well as with
home office.

according to the functional requirement complying strictly to the equipment
manufacturer‟s instructions.

Contractor shall deploy his operators for the purpose of initial operation duration & after
successful completion of the initial operation, the control of the equipment then shall be
taken over by the client.
In case during the period of equipment performance as well as initial operation &
maintenance, certain defects are discovered on the deliveries, these are identified,
analysed & if so required, replaced or repaired as agreed with the Engineer or Client.
The operation & maintenance period recommences until it is evident that no further
defects exist on the deliveries.

There could be included within the contract modalities any condition of damage
compensation to the client applicable because of equipment performance test failure,
which case requires the EPIC contractor to make compensation to the Client of the
calculated claimable amount for the failure of the required deliveries performance of the
technology. This is very significant condition in the sense that compensation may
amount to many times the cost of the works. The contractor should be careful during
initial operation & maintenance by keeping controlling eyes on all systems & discover
any minor or major defects appearing on the operation & if detected any defect, must be
brought to the knowledge of the engineer & client for the agreement of the corrective
steps to be taken & after correction, re-operation commenced for the successful initial
operation completion duration.

The different levels at which involvement of TPC are required shall include, but not be
limited to, the following:

Material Traceability Level
Any material under the following categories (Traceability Levels) shall require specific
certification or documentation as given below:

Level 1 - Full Material Traceability
The TPC shall review the data books of manufacturers and witness all the tests in
accordance with DIN 50049 3.1C or equivalent. These items shall be fully traceable.
Level 1 includes Critical System, structures and components where failure could result
in:
A significant hazard to personnel. A significant loss of production. A significant
environmental hazard.
For example certification of Level I may include: ANSI/ASME B31.3, Generators,
Switchgear, Transformer, Craneage and supports

Level 2 - Material Traceability
The TPC shall ensure that the materials supplied to the Project can be traced back to
Manufacturer‟s Certificates (DIN 50049 3.1B or equivalent), which shall be compiled in a
data book and delivered with the equipment package. It is to be ensured that the
marked up drawings are supplied to Client for reference and traceability purposes.
Level 2 certification is applicable to:
Critical system, structures, components where failure could result in:
A limited loss of production, A limited environmental hazard.

Level 3 - Material Traceability
The material shall have a Certificate of Compliance (DIN 50049 3.1A or 3) Level 3 is
applicable to material that is not in level 1 & 2.
Example of system / unit to be included in level 2, Any process system non-process
wetted or non-pressure parts which are not in level 1 or 2.
Materials not in levels 1 & 2 e.g. hand rails, floor plate, cable tray.
Minor items e.g. sacrificial spool pieces of low value and non-hydrocarbon duty, etc,
Produced water, Lube oil, Instrument air.

Packages
The traceability level for an equipment package can be found by using level 1. The
component parts of an equipment package do not warrant the same level of traceability.
The certification type should always be considered consistent with the high criticality
and type of equipment / material being designed, procured or fabricated. Consideration
needs to be given to the applicable international codes and standards to which the
particular equipment is being built.

relevant authorities under the direct control of the document controller. All contractual
documents, schematic drawings, design drawings, approved for construction
documents, specifications, red line mark ups, deliveries, inspections, procedures &
others, shall be kept in the centre for an easy reference / review for the authorized
personnel. Only controlled copy shall be issued to the designated personnel for
reference as well as official use.

Issued for Construction documents-
These documents are meant for the construction purpose having due approval by the
engineer & the Client. Without an availability of these documents, no work shall be
allowed on site. The site personnel should ensure that the documents under use are
approved for construction by making an enquiry from the document control centre.
Document control shall immediately affix the superseded seal on the documents not to
be used any further. These documents are also given various sequence of revision
depending on the changes effected thereto. The document control shall regularly
update the register of the documents showing these changes & revision references &
circulate to the designated personnel.

Red Lines Mark ups- basis for As Built documents
Every operation on site should go smoothly when all details are available. There shall
be instances due to the site requirement of actual conditions, which possibly might not
have been included during the original design, that need immediate attention & effects
to a certain extent the site for adjustments on the practical execution of the design after
the approval by the engineer is granted. These changes on the site shall be recorded on
the drawings or the specifications temporarily as red line markings/markups to be used
as records for producing as built records. Every red line mark up shall be intimated to
the engineer for the purpose of obtaining an approval for as built production. These
shall be recorded in the document control as regular documents.

As built-
Every project requires documentation for the works done on site for the final handover
dossiers. Those changes recorded as redline markups shall be properly studied by the
discipline or the project engineers one by one to decided whether or not these changes
should be reflected on the approved for construction documents. All redline mark ups
shall be incorporated on to the as built title drawings before the submission to the
engineer as project dossiers. Separate documents references shall be used for the se
documents for an easy reference as well as traceability.

Operation & maintenance Manuals
All equipment belonging to every discipline procured from any vendor shall be used on
operation of the facility permanently under proper maintenance. The responsible facility
operators should know explicitly how these machines or the equipment to be used. The
respective vendors should provide all operation & maintenance manuals for the
reference of the user describing fully to meet all normal as well as emergency
requirement. The Contractor shall submit these manuals after processing formally as
documents for approval by the engineer. These shall also form part of the handing over
dossiers.

Before the mechanical completion as a part of the pre commissioning stage, joint
inspections are carried out to enlist the minor defects as snags for all items one by one
according to the approved checklists. These leads are given by the quality assurance &
control department jointly with the construction & engineering. These notes of snags are
recorded & a time frame agreed to incorporate the correction to items that are
correctable. The items that need replacement because of defects shall have to be
replaced immediately without any delay so as not to adversely affect the project
handover. After conducting the correction to these snags, inspections are made & final
list is prepared for minor defects that may not effect the commissioning or the
performance of the facility which may be taken up to be repaired during maintenance
stage to the agreement of the parties concerned.

Visual defects-
It shall be easier to some extent for which prosecuted items may allow visual
inspections for the purpose of full or part acceptance admissible within the quality
assurance procedures. Item should then be closely inspected from inside & outside
according to the procedures specified on the Inspection & test check list. Whatever
observation made, should be recorded & final interpretation punched for further action
which shall decide the level of acceptance & suggest the further remedial action
applicable. These types of repairs should be immediately carried out to avoid
unnecessary inclusion on the punch list.

Technical defects-
Where technical defects have been noted on records pertaining items, amounting to
severe nature, that case invites items to be replaced immediately to avoid any delay on
the start up. In case defects amount to very minute nature which do not necessarily
invite replacement action, touch up repair may be agreed with the engineer & after
agreement, according to the procedures the repair be effected for re inspection &
acceptance.

Minor non-conformance-
Where a non-conformance has been recorded to repair minor defects, should these
defects be repairable, after agreement of the proposal with the engineer, the repair be
conducted & approved by re examination.

Snags-
Snags have been covered in aforesaid explanation but should be dealt with all
according to site requirement & the item concerned. Some snags may require
replacement of the item in full that should immediately be effected to avoiding any delay
on the performance of the system.

Investigations / rectification / remedial measures-
During the inspection many categories of the snags for punch list shall be observed &
pointed out. All these should be recorded & some important snags noted which amount
to sloppy quality assurance for which investigation must be resorted immediately to
establish the responsibility of neglect during supervision.

Based on these reports of investigation & punch list reference, Non conformance
reports should be constituted, thereafter resolution recorded on these for „acceptance &
implementation‟ following which, the execution of the resolution, re-inspection &
approval process repeated. Precautionary measures as revealed by the investigation of

bases shall be used in the design of steel structures. Use of fixed base plates for certain
type of pipe racks and buildings may be necessary because of deflection
considerations. Where headroom, access or equipment arrangement permit, wind and
other lateral loads on a steel structure shall preferably be transferred to the foundations
through vertical X-bracing or K-bracing included on the transverse and longitudinal
column lines of the structure. As a second choice, wind and other lateral loads on a
structure should be transferred to the foundations through moment resistant frames in
one direction and vertical X-braced or K-braced frames in the other direction. Structures
that resist lateral load with rigid frame systems in two directions should be avoided. The
method of bracing selected for a structure should generally be used throughout the
structure. Compression bracing for steel structures shall normally be designed with wide
flange and structural tee shapes. For tension bracing, single angle or structural tees
may be used. Double angle bracing because of maintenance difficulties shall not
permitted for either compression or tension locations. When using structural tees in
compression, the design shall include bending induced by eccentrically loaded
connections. Braces for structures subject to vibration from equipment shall be
designed as compression members. Horizontal bracing shall be provided in the plane of
a floor, platform or walkway when necessary to resist lateral loads or to increase the
lateral stiffness of the unit. Floor grating shall not be allowed to resist lateral loads in
diaphragm action without investigated. In a floor system, beam compression flanges
should be considered to be fully braced when a concrete slab is cast to match the
bottom face of the compression flanges on both sides or when chequered plate is bolted
or welded to the compression flanges or when grating or metal deck is welded to the
compression flanges. Grating shall normally be clipped or bolted and therefore, shall not
be considered as adequate compression flange bracing. In such cases, additional
vertical and / or horizontal bracing in the floor system shall be provided. Bar joist floor
and roof systems are generally considered to be too light for heavy industrial plant work.
However, when approved by the Designer, bar joist systems may be used on a project.
Steel Structures shall be designed so that the surfaces of all parts be readily accessible
for inspection, cleaning and painting. Pockets for depressions which would hold water
shall be provided drain holes or otherwise protected.
Connections for steel structures shall conform to the following requirements:
Shop connections may be bolted or welded. Field connections shall normally be bolted
however, when approved by the Designer, welded field connections may be used.
Bolted connections for primary members shall utilize high-strength bolts conforming to
ASTM A325 or A490. A minimum of 2 M20 bolts shall be used for all connections.
These connections shall be designed as bearing type. Those connections subject to
vibration or stress reversal shall be bearing type. Loads for bearing type connections
shall be based on threads excluded from shear plane. Turn of the nut method or load-
indicator washers shall be used for tightening all connections. Bolted connections for
secondary members (e.g. purlins, girts, stair framing. etc.) shall be made with A307
bolts with the appropriate finish. Connections will normally be designed by the Supplier
and checked by the Designer in accordance with the project construction specifications
and loads shown on the drawings. Moment connections and special connections,
however, shall be worked by the Designer duly shown on the engineering drawings.

Moment connections can be bolted or welded type depending on the type of structure
and situation. The Designer will determine the type of connection to be used for each
structure. All shear connections shall be designed and detailed by the Supplier and
checked by the Designer. Reactions shall be shown on the engineering drawings or as
per the calculation note provided by Designer. Plant area shall have the primary

structural connections continuously seal welded except high strength bolted field
connections. Primary structural connections include horizontal and vertical vessel
supports, beams and columns on major pipe racks, inaccessible maintenance areas,
etc. The forces in truss members and all main bracing shall be shown on the
engineering drawings with plus signs indicating tension and minus signs indicating
compression or as per the calculation note provided by Designer. The minimum
thickness of any structural steel plate or bar shall be 10 mm. Gusset plates shall not be
thinner than the members to be connected and shall have a thickness of at least 10
mm. Welded steel grating for platform covering shall be 30 mm x 6 mm bearing bars at
30 mm on center. Cross bars shall be twisted square 6 mm on each side and spaced
not over 100 mm center to center, hot-dip galvanized in accordance with ASTM A123
and A143 for corrosive environment. E70xx welding electrodes shall be specified for all
shop and field welding of structural steel. All welds shall be continuous. All bracing shall
be arranged to minimize torsion and where practicable, be arranged concentrically
about the resultant line of force. The connections wherever possible, shall be arranged
so that their centroid lies on the resultant of the forces those members intended to
resist. When the condition cannot be achieved, the members and connections shall be
designed to resist any local bending due to the eccentricity of the force. In practice, it is
noticed that corroded steel plates and bolts limit the expected movement which may
result in additional stresses. The Designer should consider this point to include
sequential additional stresses in their design consideration. Steel structures supporting
equipment shall be fireproofed where required by risk & safety analysis.

Reinforced concrete structures and foundations
Cast-in-place or situ concrete structures shall be designed in accordance with ACI 318
except as indicated otherwise in this specification.
Cast-in-place or situ concrete structures shall be designed for the loads and load
combinations required according to codes & description elsewhere in project
documents. The working strength or limit state of serviceability design methods shall be
used for the structural design of concrete members unless otherwise indicated. Load
combinations and load factors for all concrete design shall be adopted in accordance
with ACI 318. The design and details of cast-in-place concrete structures shall consider
the monolithic nature of hardened concrete.

Construction joints in a concrete structure shall be located so as to least impair the
integrity and unity of the structure. Construction joints in beams at column or pedestal
faces should be avoided. The Designer / Contractor Site Management shall approve the
location of all construction joints on site agreement. Moving concentrated loads on
elevated concrete beams and slabs shall be treated in accordance with applicable
recommendations of the referenced AASHTO specifications. Slabs at grade for
buildings and process areas shall be designed in accordance with the publications
„Concrete pavements for heavy storage areas‟ Underground structures such as
basements, rectangular tanks, sumps, and pits shall be designed in accordance with the
latest referenced PCA bulletins and / or BS8007. The design of such structures shall
include the effects of ground water pressures and buoyancy. A minimum factor of safety
of 1.1 for buoyancy shall be used ignoring soil cohesion. Concrete process treatment
structures shall be designed in accordance with ACI 350 R. For all liquid retaining
structures, special precautions shall be taken for water tightness. All joints shall be fully
detailed by Designer. A corrosion allowance of 3 mm shall be required for all anchor
bolts. Bolts shall be hot-dip galvanized in accordance with ASTM A123 and A143.
Foundation design in addition to the above applicable criteria shall meet the following

requirements: Foundations shall be designed in accordance with the project
geotechnical (soils) report. Foundations for structures shall be sized and stability
determinations made using service loads only. Load factors shall not be included in
these design operations. Unless there is a conflict with the project soils report, individual
foundations shall normally be used for major equipment. If combined foundations are
appropriate, the centroid of the bearing area should coincide with the resultant of the
applied operating load (excluding live load). All foundations shall be placed on sealed
blinding concrete on firm, undisturbed soil. Some seal slabs, however, may be placed
on well-compacted earth fill, if approved by the Designer. In such cases, the
engineering drawings shall specify the kind of fill material and the degree of compaction
required for the fill material. Spread footings, combined footings and mats should be
designed assuming linear soil pressure distribution. Where the rigidity of the foundation
is questionable, an analysis considering the interaction between flexibility of the
foundation and the subgrade soil reaction should be considered. For mats particularly,
this method of analysis may be in order. ACI 336.2 R contains suggested design
procedures. Foundations shall be proportioned so as to minimize general and
differential settlements. In order to reduce the overturning moment on individual footings
of buildings and process structures, the transfer of column base shears into the
concrete grade slab should be considered. The frictional resistance provided by the
grade slab shall equal at least 1.15 times the applied column base shears. For design
purposes, a coefficient of friction of 0.2 may be assumed between the concrete slab and
the membrane. If this design approach is used, the grade slab thickness and joint
details shall be properly designed. Where seasonal changes in soil moisture content
occur extremely, special details may be required to minimize foundation movements.
Control of foundation movements is especially critical for masonry structures. The
Designer shall determine design parameters to control such movements.
The stability ratio (SR) based on service loads for isolated spread footings shall not be
less than 1.5 when determined as follows:
SR = D (P) / 2M = D / 2e Where: D = Diameter or width of footing, P = Minimum gravity
load at bottom of footing (exclude equipment and live loads, include buoyancy), M =
Maximum overturning moment at bottom of footing, e = Eccentricity = M / P
The uplift factor of safety based on service loads shall not be less than 1.25. This factor
of safety must be maintained when 70 percent of dead load is combined with no
reduction of wind load for uplift.
The stability ratio (SR) based on service loads for buildings, process structures and
other framed structures shall not be less than 1.5 when determined as follows.
SR = Resisting Moment / Overturning Moment Where Resisting Moment = Moment due
to dead load of foundation and structure (include buoyancy), Overturning Moment =
Moment due to lateral loads
The overturning and resisting moments shall be computed about the most critical axis of
rotation of the foundation block at the soil / concrete interface. There may be more than
one axis of rotation.
The stability ratio (SR) of retaining walls based on service loads shall not be less than
the following.
a. For sustained loading:
SR = Resisting Moment / Overturning Moment
= 3.5 for cohesive soils
= 2.0 for cohesionless material
b. For sustained loading combined with temporary loading:
SR = Resisting Moment / Overturning Moment
= 2.0 for cohesive soils

= 1.5 for cohesionless material
Where:
Resisting Moment = Moment due to dead load of wall and soil overburden (include
buoyancy)
Overturning Moment= Moment due to lateral loads
Resisting moment and overturning moment shall be taken about the toe of the retaining
wall and bottom of footing. For all service load conditions, the sliding resistance of
foundations especially retaining walls, shall at least be equal to 1.5 times the applied
lateral loads. Sliding resistance shall be developed by either friction between the footing
and membrane or by passive resistance of shear keys extending below the bottom of
the footing in the case of retaining walls. In cases where sliding resistance is developed
by a combination of friction and passive resistance, it is recommended that a minimum
factor of safety of 2.0 shall be provided. Stability calculations shall include the weight of
the foundation concrete and the soil immediately above the footing(s). The effects of
buoyancy on the concrete and soil weights shall be considered. Passive earth
pressures shall not be included in stability calculations except in the design of retaining
walls with keys. In this case, only that pressure acting on the key face shall be
considered. Foundation bottom level shall be defined taking into consideration
geotechnical (soil) report and other factors to be clearly noted on the drawings. Keep
standard bottom of footing elevations where possible. Consideration shall be given to
interferences with underground soil systems.
General
The Region has been defined as being in an Ultra Hot Climate t together with the
extremely heavy concentration of chlorides in both the ground and atmosphere together
with high humidity that result in the rapid degradation of Reinforced Concrete structures.
The degradation of the concrete is principally caused by reinforcement corrosion due to
the ingress of chlorides and other aggressive salts, the consequential increased volume
of rust produced commonly breaks off the cover on the reinforcement. Failure of the R.C
member then becomes imminent. The degradation of concrete arises also from the use
of salt contaminated materials. The durability and quality of the concrete itself is of
paramount importance. Factors to increase durability while designing shall be
considered in concrete such as thermal insulation coating measures as recommended
in the “CIRIA Guide to Concrete in The Gulf Region”. Quality of concrete is achieved by
good engineering and detailing proper materials and proportioning good construction
techniques and concrete curing. One of the main characteristics influencing the
durability of concrete is its permeability to the ingress of chlorides, water, oxygen,
carbon dioxide, wind blown chloride contaminated dust and other deleterious
substances. Coatings shall be applied to all buried and exposed concrete surfaces as
an essential protection against attack from chlorides, other harmful elements and to
provide the concrete to develop a refined pore structure enhancing impermeability.
Coatings shall have crack bridging properties on flexural members. Steel plates shall
not be embedded in concrete. The Contractor shall develop a detail that allows
attachment of the plates to inserts embedded in the concrete. A detail shall also be
developed to ensure an effective seal from exterior moisture is achieved around the
perimeter of the plates at the point of intersection between concrete and plate.

Crack prevention
Crack widths shall be controlled by an expeditious use of combinations of reinforcement
sizes, spacing and cover.
Crack widths shall be calculated using the applicable formula in BS 8007.

The calculation shall be based on the long term, steady state loading. For durability it is
not necessary to consider peak loadings although this may affect coating selection for
the requirement for crack bridging and flexural performance.
Crack widths apply at the surface of the concrete i.e. the full depth of cover shall be
utilized in the calculation.
Calculation of crack widths shall consider both load (flexural) and restraint (due to
thermal and shrinkage effects) induced cracking.
In order to reduce flexural cracking to acceptance limits, it will be necessary to use
reduced allowable stresses in the reinforcement.
Calculation of crack widths shall not use „deemed to satisfy‟ options of BS 8007, i.e. do
not calculate crack widths on PC and minimum reinforcement ratios.
The minimum external restraint factor (R) shall be 0.5.
Methods of calculating crack widths in relation to temperature and moisture effects are
given in Appendix A - BS 8007.
The minimum fall in temperature between hydration peak and ambient (T1) shall not be
less than 31° C for walls and 21° C for ground slabs.
Seasonal temperature fall (T2) shall be considered where continuous construction is
used - BS 8007 - Table 5.1 - Option 1. This shall be not less than 30° C.
Crack widths shall be limited as follows.
Crack width shall be = 0.15 mm for all buried, submerged and exposed concrete.
Crack width shall be = 0.30 mm for all concrete located in an air conditioned and sealed
environment.
Crack widths shall be = 0.10 for all liquid retaining structures.

Reinforcement
Use smaller diameter re-bar at closer centers.
For sections = 500 mm thick and for the outside 300 mm of large sections,
reinforcement shall not be less than 0.35% of the applicable gross cross-sectional area
of the concrete section.
Maximum spacing of reinforcement shall be 150 mm in any direction.
Use fabric reinforcement where possible („nested‟ where necessary) as this gives better
crack control.
Do not bunch reinforcement or use in vertical or horizontal pairs.
Reinforcement shall be adequately detailed to eliminate congested areas i.e. laps to be
staggered.
Place reinforcement nearest to the surface where it is the greatest restrained length
which means horizontal wall reinforcement will be on the outside of the vertical
reinforcement.
Ensure additional diagonal reinforcement is placed at each re-entrant opening to
prevent cracks emanating from corners.
All reinforcement shall be fully detailed by the Designer on bar bending schedules BBS
for fabrication.
All concrete sections with a thickness of 250 mm or more, reinforcing bars shall be
placed on both faces over the full section. In addition, minimum reinforcement shall be
placed in the other two faces.
Concrete Cover
Adequate cover to the outside of all reinforcement is essential for resistance to
corrosion for all types of sections & situations whatsoever..
Minimum Concrete Cover (mm) Concrete cast against or permanently exposed to earth
(all below grade structures) and all marine facilities over or in contact with water 75

Where any individual structural element falls within two or more categories then the
most stringent criteria shall apply for the entire element.

Horizontal re-bar in walls and faces of large elements shall be on the outside of the
vertical reinforcement for more effective crack control.
All concrete cover shall conform strictly with values given above unless noted otherwise
on design documents or in the applicable standards.
Required covers shall not be reduced by provision of protective coatings, membranes or
by membrane protective screed.
If fire resistance of more than 2 hours is required, cover shall be as determined in Table

Concrete Grades
Concrete shall have a minimum compressive strength as given in Specification for
Concrete


Externals Features
Features which collect sand and dust that can form with rain or dew into a corrosive
pollutant shall be avoided i.e. decorative patterns with holes and pockets, gutters,
ledges and exposed aggregate finishes. Top surfaces shall be designed with falls to

of the load will be given in the equipment specification. The project process engineer
shall furnish a list of equipment having surge loads and the designer make allowance
for such loadings in relevant calculations.

Truck Load (Live Load)
Structures accessible to trucks shall be designed to withstand the gravity, lateral and
impact effects of truck loading. Truck loading shall be HS20 or HS20-44 wheel loading
as defined by the AASHTO specifications. It shall be checked where applicable whether
maintenance and / or construction equipment loads are governing over HS20 wheel
loading. At least one road leading to the main process area(s) shall be designated as a
heavy equipment route. Bridges, culverts and other underground facilities shall be
designed for the maximum expected loading condition caused by transportation of
heavy equipment

Wind Load (Live Load) The design wind loads shall be calculated based on a basic wind
speed of 145 km per hour at a height of 10 m above the ground for terrain exposure C
and a mean recurrence interval of 50 year. For this exposure and recurrence, the value
of the importance factor of (I)=1.1. The Designer shall

piping, ladders and platforms.
The „shape increase factors‟ may be used to modify the projected areas of vertical and
horizontal vessels (including insulation if any) to allow for attachments such as
manholes, nozzles, piping, ladders and platforms. Use Cf = 0.8.
Wind loads shall be separately computed for all supported equipment, ladders, and
stairs except for vessels where „projected area increase factors‟ have already been
accounted for these items. Gust response factors G for main wind resisting systems of
flexible buildings, structures and vertical vessels having a height exceeding five times
the least horizontal dimension or a fundamental natural frequency less than 1.0 hertz
shall be calculated. Calculations shall be based on a rational analysis that incorporates
the dynamic properties of the main wind force resisting system. One such procedure for
determining gust response factor is described in ASCE
No reduction shall be made for the shielding effect of vessels or structures adjacent to
the structure being designed.
For main wind force resisting systems and walls, use Gh evaluated at the height h (top)
of the structure. An exception is in the various structural specifications for equipment,
the variable gust response factor Gz is used. For components and cladding, use Gz
evaluated at centroid height z above ground.

Earthquake Load (Live Load)
Earthquake load shall be applicable according to project Location & in conformance to
Uniform Building Code (U.B.C.) 1997-Division III-Seimic zone Tabulation Section 1653.

Crane / Impact Load (Live Load)
For structures carrying live loads that induce impact, the live load shall be increased
sufficiently. If not otherwise specified, the live load increase shall be following:
Category

3. Live load on crane support girders shall be taken as the maximum wheel loads.

Dynamic Loads (Live Load)
Each structure shall be designed to withstand the effects of vibration and impact to
which it may be subjected. Each structure and foundation supporting a compressor,
turbine, pump or other machinery having significant dynamic unbalance shall be
designed to resist the peak loads specified by the manufacturer. Vibration amplitudes of
the supporting structure or foundation shall
be kept within acceptable limits for dynamic forces that occur during normal machine
operation. In the case of a tall and slender structure, there may be a need to investigate
the dynamic effects of wind gusts.
Centrifugal pump foundations for pumps less than 750 kW do not require a dynamic
analysis. However, the foundation to pump assembly weight ratio shall not be less than
3 to 1.
Foundations for reciprocating machinery, centrifugal machinery and centrifugal pumps
over 750 kW require a three dimensional dynamic analysis.

Thermal Load (Live Load)
ASCE 7 mentions thermal loads however, the ASCE thermal comments are not geared
to heavy industrial work. Thermal loads shall be defined as forces caused by changes in
temperature. The primary source of thermal loads in an industrial plant is the expansion
or contraction of vessels and piping. Another source of thermal loads in a redundant
structure is the expansion or contraction of the entire structure or individual structural
components. Provisions shall be made for thermal forces arising from assumed
differential settlements of foundations and from restrained dimensional changes due to
temperature changes. Thermal loads and displacements caused by operating
conditions shall be based on the design temperature of the item of equipment rather
than the operating temperature. Design atmospheric temperature ranges from a
minimum of 5 deg C to a maximum of 58 deg C. Low friction slide plates (Fluorogold,
Teflon / PTFE or an approved equal) shall be used if the vessel operating condition
weight is greater than 45 kN at the sliding end. For preliminary design, the temperature
drop of 1.9 deg C / mm from the bottom of shell to bottom of saddle may be assumed.
The following friction coefficients shall be used for calculating frictional restraint due to
temperature change or lateral loading on sliding surfaces:
Surface Friction Coefficient
Steel-to-steel (corroded) 0.35
Steel-to-concrete 0.50
Teflon-to-teflon
A straight line variation of 0.17 to 0.08 for bearing Stresses from 0.0 N/mm2 to 0.7
N/mm2, respectively Bearing stress greater than 0.7 N/mm2 0.17 to 0.08
0.08
Graphite-to-graphite 0.15
For computing friction loads due to the effects of pipe expansion in pipe racks, use the
following friction coefficients:
Number of Lines on Support
Friction Coefficient
1 – 3 0.3
4 - 6 0.2
7 or more 0.1

For a given support, if considering only larger lines and ignoring smaller lines results in
greater loads. These forces and associated friction coefficients shall be used instead of
considering all the lines.

A concrete pipe rack beam shall be designed for an arbitrary horizontal pipe anchor
force of 15 kN acting at midspan unless design calculations dictate a higher force and
more locations. The pipe anchor force shall not be distributed to the foundations.

For pipe anchor forces transferred by longitudinal girders to structural anchors (bracing)
an arbitrary force of 5% of the total pipe load per layer shall be taken into account
unless design calculations dictate a higher force. These forces shall be distributed to the
foundations.
Foundations and structures which are subject to temperature effects shall be designed
for the various loading conditions and also for any temperature difference which may
occur in parts of structural members.
a. Anchor and guide forces shall be obtained from the Designers Piping Engineering
Department.
b. Structural Steel Pipe Supports shall be designed in accordance with Industry

Standard Structural Design Methods.
Erection Dead Load
The erection dead load is the weight of the equipment at time of erection plus the weight
of the foundation. The foundation weight is the combined weight of the footing, pedestal,
and overburden soil.

All possible loading conditions during erection shall be considered and for any member
of a structure, the most unfavorable be considered.

Heavy equipment lowered onto a supporting structure can introduce extreme point
loads on structural members exceeding any operating or test load. After placing of
equipment, the exact positioning (lining out and leveling) can also introduce extreme
point loads. The above should be interpreted on the basis of contractor‟s practical
experience, manufacturer‟s information and allowed for in the design calculations
accordingly.

Beams and floor slabs in multistory structures e.g. fire decks shall be designed to carry
the full construction loads imposed by the props supporting the structure immediately
above. A note shall be added on the relevant construction drawings to inform the field
engineer of the adopted design philosophy.
Maintenance Loads (Live Load)
Maintenance loads are temporary forces caused by the dismantling, repair or painting of
equipment.
The force required to remove the tube bundle from a shell and tube heat exchanger
shall be assumed to act along the horizontal centerline of the exchanger with a value of
2 times the weight of the bundle but not less than 10 kN.
Miscellaneous Loads (Live Load)
Miscellaneous loads shall be defined as loads that do not fit into the categories listed in
this section.
Earth / Hydrostatic Load and Buoyancy (Live Load)

Earth and hydrostatic water pressures on retaining walls and underground structures
shall be determined. Outward pressures on liquid retaining structures shall also be
considered. The buoyancy load is equal to the weight of the volume of displaced water.

Blast Load (Live Load)
Negligible Blast
Buildings located more than 610 m away from the potential explosive sources do not
require special provisions with regard to explosion resistance.
Blast Resilient
Buildings within the 200 m to 610 m distance from potential explosive sources shall be
designed to the same loading conditions as specified for buildings beyond the 610 m
zone and in accordance with the following design concepts:
The building structural frame, roof, walls, bracing and connections shall be designed in
such a manner that large plastic deformations of the major frame members as well as
external wall panels will be allowed to occur without causing partial or total building
collapse. Blast resilient buildings shall be designed and detailed in accordance with ACI
318, Chapter 21, “Special Provisions for Seismic Design”.
The building frame shall comprise of reinforced concrete or structural steel.

designed carbon steel roofing system. Loose lightweight concrete roof slabs or
asbestos cement sheeting shall not be used. Gravel as a protection of roofing finish or
loose tiles for walkways on top of the roof finish shall not be used.

For steel structures, structural steel bracing in roof and walls shall be provided.
Materials with a brittle behavior such as masonry shall not be used in such a way that
provides strength.

For additional architectural construction requirements, refer to Specification for
Architectural Design Basis (Not included)

Blast Resistant
Buildings within 200 m distance from the potential explosive sources may be designed
to withstand the anticipated blast effect. The blast loads or pressures to be used for the
design of various structural elements shall be calculated in accordance with an
acceptable method taking into account the dynamic response. The calculated blast
loads shall not be less than the following equivalent static loads acting inward or
outward perpendicular to the surface:
External Walls 100 kN/m2 except loads on doors and windows which may be assumed
to be 30 kN/m2.

It is to be assumed that the blast loads will act simultaneously on and over one wall and
the roof. These loads act with applicable dead loads. Suction on walls and roof shall be
50% of the above-mentioned static loads and it is to be assumed that these loads will
act simultaneously on one wall, the roof and not in combination with above-mentioned
loads.

Structures shall be detailed in accordance to ACI 318, Chapter 21 “Special Provisions
for Seismic Design”. Pre-stressed concrete shall not be used. In general, special
attention shall be paid to ensure continuity and a minimum of local stress concentration.
Adequate lapping of reinforcement is required. The following provisions shall supersede
ACI 318, Chapter 21 for Blast Resistant structures:

The concrete walls and slabs shall be reinforced each side in the main direction with a
minimum of 0.6% in the case of steel bars with a yield strength of 410 N/mm2 and a
minimum elongation of 14%. In the other direction on both sides, a distribution
reinforcement of at least 20% of that in the main direction shall be applied. Maximum
spacing of bars shall be 150 mm center to center. It is preferable for the wall and roof
thicknesses to be between the limits of 250 and 400 mm in order to facilitate the placing
of the required reinforcing bars. Shear reinforcement shall be applied in beams only
being a combination of stirrups and horizontal sidebars: web reinforcement.

Vibration

Superstructure Vibration
The primary source of vibration in superstructures is harmonic unbalanced forces
generated by rotating or reciprocating equipment. The final design should be such that
vibrations will be neither intolerable nor troublesome to personnel and not cause
damage to the machine or structure or adjacent foundations, structures or services.
As a general rule, none of the natural frequencies of the structure should be within a
band of the operating frequency of the supported machinery. The band recommended
to be avoided is 1.414 above operating frequency and 0.707 below operating frequency.
To find structural natural frequencies, a computer analysis shall be required.
All natural frequencies below 2 times the operating frequency for reciprocating
equipment and below 1.5 times the operating frequency for rotating equipment shall be
calculated.
It shall be demonstrated that the amplitudes at the natural frequencies between 0.35
and 1.5 times the operating frequency are within the allowable values even assuming
that, due to differences between the actual structure and the assumed model,
resonance does occur. In this case a reasonable amount of damping should be
estimated.
Resonance condition requires a detailed three dimensional dynamic analysis. Once a
model analysis has been conducted, a harmonic response analysis shall be performed.
The response analysis will indicate anticipated amplitudes of vibration, velocity, and
acceleration as well as magnitudes of forces in structural members. From the above
information, the adequacy of the design can be evaluated and if necessary,
modifications may be made.
The maximum vibration amplitude of the equipment shall not exceed the lower of the
following values:
a. The maximum allowable values stated by the manufacturer of the equipment.

b. The amplitude (single amplitude) which causes the effective velocity of vibration to
exceed:
2 mm / s at the location of the machine bearing housings
2.5 mm / s at any location of the structure
c. The dynamic amplitude of any part of the foundation including any reciprocating
compressor shall be less than 80 µm single amplitude (80 x 10^-3mm).
The effective velocity is defined as the square root of the average of the square of the
velocity, velocity being a function of time. In the case of a pure sinusoidal function the
effective velocity is 0.71 times the peak value of the velocity.
The depth of a steel beam supporting large open floor areas free of partitions or other
sources of damping should not be less than 1/20 of the span to minimize perceptible
transient vibration due to pedestrian traffic.

Foundation Vibration
The Designer shall determine which vibrating equipment is to be analyzed by dynamic
analysis.
Dynamic Analysis
For foundations for reciprocating machinery, centrifugal machinery and centrifugal
pumps 750 kW or over, a three dimensional dynamic analysis must be performed.
Foundation vibration generally involves a grade foundation designed to support one or
more reciprocating or rotating machines.
Generally the same considerations for superstructure vibration also apply to foundation
vibration.
The primary differences are that these foundations are often rigid blocks and that soil
behavior must be considered. Rigid foundations supporting only one major machine can
readily be analyzed using hand calculations and the concept of elastic half-space
theory. For flexible foundations or foundations with many machines, a computer
analysis should be utilized along with the concept of elastic half-space theory. The
Designer shall prepare an instruction for foundation vibration analysis which contains
current state-of-the-art approaches, soil information, machine information, dynamic
analysis aids, published response criteria, example solutions, and a comprehensive list
of references.
The dynamic amplitudes of any part of the foundation including any reciprocating
compressor shall be less than 80 µm (80 x 10^-3 mm) single amplitude.
For the dynamic analysis, the exciting forces shall be taken as the maximum values that
according to the Manufacturer of the equipment will occur during the lifetime of the
equipment. When the exciting force is not given by the Manufacturer, it shall be
determined from
Q(kN) = [Rotor Speed (rpm)/6000] x Rotor Weight (kN)
The dynamic calculations shall be based on a mechanical model wherein the weights
and elasticity of both structure as well as foundation and the weight of the equipment to
be represented in an appropriate way.
All natural frequencies below 2 times the operating frequency for reciprocating
equipment and below 1.5 times the operating frequency for rotating equipment shall be
calculated.
It shall be demonstrated that the amplitude of the natural frequencies between 0.35 and
1.5 times the operating frequency are within the allowable values even assuming that,
due to differences between the actual structure and the assumed model, resonance
does occur. In this case, a reasonable amount of damping should be estimated.
The natural frequency of the supporting structure shall not coincide with any resonant
frequency of the equipment.

shall include but not be limited to the following causes of deformation.
Shrinkage and creep of concrete.
Temperature effects caused by radiation and convection of heat or cold generated by
machinery, piping, and ducting.
Elastic deformation caused by changing vapor pressure in condensers.
Elastic deformation caused by soil settlement.

Non-Dynamic Analysis
For installations that do not warrant a dynamic analysis, (equipment weight less than
5000 kN), the mass ratio concept is commonly used. In the design of equipment
foundations subject to vibratory loading where dynamic analysis is not performed,
foundations shall be proportioned as indicated below:
Rotating equipment mass ratio = weight of concrete / weight of machine > 3
Reciprocating equipment mass ratio = weight of concrete / weight of machine > 6

Clearances and accessibility
Minimum clearances for Equipment, Structures, Platforms and Supports shall be in a
accordance with the table in Specification for Design, Layout and Drawing

HRW Hydraulic Study Notes Conclusions
Contractor shall consider HRW studies conclusions as given below.

This Technical Note has described a design review and a computational fluid dynamic
model study of the proposed Plant CCWS pumping stations

The study has considered the most recent estimates of the design flow rates,
comprising -------m3 / hr from Pumping Station ------- m3 / hr from Pumping Station and -
----------- m3 / hr from Pumping Station .

Design flow conditions at the entrance / inlet to the pumping station
The water levels at the pumping station entrance and the approach flow patterns
considered in the analysis took account of the flow into Pumping Station. The minimum
water level of -0.95m NHD corresponds to a head loss of only 0.07m in the channel.
Approach flow patterns are direct and well-behaved.

Review of layout in relation to design guidelines, etc.
The typical maximum approach flow velocities to the bar screens are considered to be
within acceptable limits in relation to potential turbulence levels at the bar screens.

In the worst case (i.e for PH-) at maximum flow, the velocity in the double-entry
channels at the drum screens shall be typically 0.86m / s. This is a little high relative to
HR Wallingford's experience of other installations and it would be appropriate to confirm
with relevant screen vendors that a maximum approach velocity of some 0.8-0.9m / s is
acceptable in the channels approaching the drum screens.

In the worst case (when one screen train is out-of-service), the maximum velocity
leaving the screen units shall be approximately 0.8m / s. This is considered a little high
in relation to the size of the forebay area, as confirmed by the CFD model. Flow
modification measures (e.g. Baffles or columns) are likely to be required in the forebay
to ensure satisfactory flow patterns under adverse combinations of screens and pumps
in operation.

Submergence of pumps
The available submergence and proposed elevation for the pump bay invert (-9.50m
NHD) are considered satisfactory in relation to the required submergence conditions for
minimisation of free-surface vortices.

Overall dimensions and internal structures
The proposed overall layout and dimensions for the screen chambers is considered
satisfactory for FEED. It would be recommended, however, that the required width of
each screen chamber element should be subject to further review / detailed design
during EPC - following identification of the actual screen vendor and actual screen
dimensions.

In the case of PH#, the initially designed pump chamber width of 5.0m is smaller than
standard guidelines would suggest. Preliminary enquiries with pump manufacturers
have indicated that a pump chamber width of 5m would be acceptable (even based
upon a bell mouth diameter of 2.7m). Taking this into account, the proposed 5m width
for each pump chamber is considered satisfactory for FEED. It would be recommended,
however, that the required width of each pump bay should be subject to further review /
detailed design during EPC - following final confirmation of the actual pump vendor and
actual bell mouth diameters.

The Initial Design for the pump bays provides for a “standardised” pump bay length of
10m, which is satisfactory with respect to the pumps for PH and PH but short relative to
standard guidelines in the case of PH#.

The proposed “standardised” distance from the rear wall of a pump bay to the pump
centre line of 2.2m is in accordance with standard guidelines.

In general terms, the splitter / benching, corner fillets and curtain wall arrangements are
considered appropriate vortex suppression devices / methods. On the basis of
"standard best practice", it is considered that these features should be included in the
pump bays, as they shall help serve to inhibit severe surface and sub-surface vortex
formations.

Free passage of air must be allowed at the top of the pump bays and other semi-
enclosed areas of the pumping stations.
The roof slab is expected to be clear of the water surface even for extreme water
level/wave conditions (notwithstanding possible transient water levels in the Intake
Channel that might result from pump start-up or trip scenarios).

The possible improvements identified for testing in the CFD model resulted from the
short pump chambers in PH and the restricted distance between the drum screen
chambers and the pump chambers.

Computational fluid dynamics (CFD) model tests
Simulations have been undertaken for a variety of operational conditions in the planned
Plant CCWS pumping station.

The calculated water level at the entrance to the pumping station takes account of the
flow into the Phase I pumping station (PH, and the intake channel model demonstrated
well-behaved approach flow to PH and PH. Therefore, although the pumping station
computational model does not explicitly simulate PH, the simulations take account of
the effect of the flow into PH.

With the original design, and under adverse combinations of pumps and screens in
operation, significant oblique flow with local velocities approaching 1m / s was observed
Page 184 of 497                                                  suraj_engineer@yahoo.co.uk

in the pump forebays. Flow in the pump chambers under these conditions was
asymmetric, locally approaching 0.8m / s and there was rotation at the pumps.

Revisions to the design have been proposed, in which columns are introduced at the
entrance to the pump chambers to dissipate the asymmetric jets. Further simulations
have been carried out to show the effects on the flow patterns. These show significantly
improved flow patterns in the pump chambers, but there is scope for further
improvement in the forebays.

The CFD model studies indicate that the overall pumping station dimensions are
adequate, subject to provision of the dissipating structures described above and
optimised during EPC.

Physical model study
To confirm and extend the conclusions of the CFD model study, it is recommended that
a physical model study be carried out during the EPC phase. This would enable final
optimisation of the internal layout, and confirmation of satisfactory performance under
the final design operating conditions. For Physical modelling scope of work Refer to

As-built Drawings
As built drawings serve the purpose of telling the user about the building records that
should be used for the purpose of maintenance/or for whatever purpose possible. It is
therefore, an important & significant part of documentation as well as also a contractual
obligation on the part of AJES & Technip which should be affected smoothly & regularly
throughout the duration of project. Should there be no change on the Released for
construction drawings i.e. the construction has been carried out all in accordance with
the approved documents provisions, there shall be no purpose of As - built drawings.
But in practice, to produce physical structures, some changes are imminent due to
arising of new requirement, changes, effects of disciplinary interfaces to bring the work
to proper use functions etc. During the whole currency of the contract, it should be an
endeavour of the AJES that all changes are recorded on contract documents as Red
Lines mark up & issued to Technip for approval. These Red Lines mark up shall form
the basis of producing all As Built documents on the project. It is not the drawings only
that are to be recorded but also all changes whatsoever for any document on record. All
these As Built shall form part of hand over dossiers. Should as built records be
maintained regularly, this part of the dossiers shall be comfortably produced. The site
design engineers shall keep an eye on this activity & record changes regularly as red
line mark up & process the documentation to fulfil the contractual obligation to this
extent possible. It is expected of the site engineers, the design engineers as well as
land surveyors to coordinate on site to comply with this obligation efficiently. All survey
changes or variations shall also be recorded on the drawings based on the pre pour &
post pour records taken from survey section. Surveyor shall present all such changes
on the corresponding documents to be recorded as Red Line Mark ups.

The following paragraphs management procedures have been included just for the
purpose of information as already covered within the New Buildings package Inspection
& Test Plans All necessary Inspection & Test Plans shall be originated by the Quality
Engineer in collaboration with Engineering in head office & Engineering in site team.
These ITPs formats shall be issued for Technip & Company approval according to the
procedures laid down on Project Quality plan. Production of all these documents shall
be the responsibility of AJES Quality Manager/Engineer. Complete details about the
quality management system have been included on the respective Quality Procedures
document. Generally, ITPs for all disciplinary activities shall be produced for Technip &
Company approval from site office in due course. All defined tests shall be conducted
by Technip/Company approved laboratory located on site. For those items the tests
shall be conducted by any Technip/Company nominated laboratory, for which facilities
are not available on site. The details of these plans shall be submitted separately. Every
ITP shall be allotted a document number along with a numbered checklist. Check list
shall form the basis of inspection requirements.
Project Controls

Project Control management requires the formation of strategies those can be utilized
optimally to achieve the target in minimum cost with best quality product

To achieve as aforesaid, it is extremely important that complete project should be
analyzed from whole to one & all necessary resources to be used or deployed should
be known in advance prior to commencement of physical works.

Preventive Measures
HSE&S
Health, Safety, Environmental & Security
Standard Procedures / Hazard Control
This procedure is applicable to all projects construction site activities.
Purpose
To establish a procedure for systematically identifying all the hazards / risks
associated with a task or job and to implement appropriate control measures.
Preventive Maintenance is of utmost significance for such an industrial project that
must be kept in full considerations while conceptualizing any scheme. There should be
a session of brain storming to find out the causes & solutions for meeting any hazard
that may crop in during the operational life of the project. Every risk must be analysed
as any miscalculation may lead to intensive fire breakout resulting in losses of billions of
dollars as well as severe human loss. There are nowadays several methods given in
industrial safety as well as loss prevention methods for the disaster management to
prevent such mishaps. The present scope of this book does not allow that to elaborate
but informatively included. Let us divide the whole plant industrial area into various
zones depending on defined & expected risks. Process area, non-process areas,
explosive zone, secured zone, administrative zone, environment unsafe zone etc

Process area can be confined to the real trains zone which is a pure chemical product
engineering portion comprising of all vessels involving oil & its storage. This is the only
major potential source leading the plant to major fire as well as explosion hazards. All
equipments must be made fireproof to the extent possible. The building contained in
such zone must be made blast resistant. All arrangements of fire suppression must be
made. Proper arrangements must be made for all personnel to use safety devices of all
kinds depending of the nature of the hazard so that all users wear preventive dressing /
equipment.

Hot as well as cold works areas are defined explicitly for the purpose of preventive
adaptation as well as for issuing permits to work within & without plant for the
engineering construction works in future. Safe procedure must be defined for such
activities. No work should be allowed without granting of such permits. The lost gases or
other products or bye products have the potential to spread into the environment air
consequently transferring fire possibility a detailed study of that should be made to find
a resolution to adopt for suppression measures.

Non process areas should be located distant enough say anything far up to 700 m from
the real trains so as the effects are not relocated to this zone that requires only blast
resilience structures. Accordingly fire suppression & blast control provisions be applied
to the constructions as well as precautionary measures be defined for the personnel.
Circulatory areas should be defined in between the process & non-process areas that
cannot be definitely delineated but shall carry piping, traffic, roads & many other
components of the plant. Accordingly the provisions be given for the disaster
management. The most important aspect is the control from fire everywhere for which
regular mockups should be conducted. Assembly points be clearly defined at various
location that allow following fire alarm to assemble & await further directions from the
wardens. Immediate medical attendants & ambulance should be installed. The piping
routes must be defined corridors with proper fire protection & guards. No unauthorized
person be allowed within the corridors.

Storage area particularly of oil raw material must be provided full protection from firing
& explosion viewpoint. This is actually a very high potential source of fire & can cause
heavy losses to industry as well as to humans. In case of fire disaster, adequately
effective arrangements must be available fully all times to vacate the personnel as soon
as possible from the assembly points & further off the plant to safer locations. All
classes of fire suppression arrangement must be kept fully functional at the relevant
hazard locations clearly defined to the personnel involved & competent fire fighting team
made available. Regular training & mock-ups drills must be conducted to keep the
involved humans alert to meet any unforeseen.
As far as adverse effects during an occurrence of earthquake are concerned,

Quality Assurance and Quality Control
Quality Management System shall comply with the applicable requirement of ISO 9001.
The purpose of the description herein is to determine factory inspection and testing
requirements for fire protection equipment, fire detection equipment, gas detection
equipment and alarm system equipment including control panels that shall be listed in
project specification. The level of shop inspection and test requirements is defined.
Description
The fire protection and extinguishing system shall include (but not be limited to):
Water supply and distribution system including pumps, mains, hydrants, monitors, hose
boxes, hose reel stations and fire point shelters. Water spray systems for process
equipment. An automatic CO2 fire suppression system inside gas turbine enclosures.
Fire, smoke and gas detection and alarm systems in process areas. Automatic fire
suppression systems protecting vital equipment inside buildings. Portable extinguishers
(dry chemical powder, carbon dioxide and water) and other movables. General building
protection (manual call points, hose reels, and portable fire-extinguishers) Fire Training
Facility


The Basis Of Fire Protection
The basic objectives for fire protection is to limit or prevent the escalation of a fire, to
avoid risk to life and to minimize material damage until the source of hazard has been
isolated or consumed. Fire protection shall mainly be provided by automatically and
manually operated fixed-installed systems in conjunction with portable and mobile fire-
fighting equipment.



Requiirrementts
 Requ emen s
Fire prevention and protection measures shall be considered during all stages of plant
design.
Process and equipment design shall be assumed as following good engineering
practices such as sufficient spacing of equipment, incorporation of emergency shutdown
system, relieving system, drainage systems and other special safety considerations for
the individual process requirements. Equipment arrangement and distances between
fire-hazardous equipment shall be set so that in the event of a fire, the possibilities for
escalation are minimized; however, within an operational complex, it is not always
feasible to achieve complete separation of equipment. Consequently, additional
precautionary measures for fire protection shall be evaluated and submitted for
Company approval. This applies particularly to those areas where a chimney effect may
occur. For example, a minor fire at a pump may affect overhead equipment causing the
fire to rapidly develop. Also, the updraft associated with air-cooled heat exchangers may
cause the fire to spread. Design of the fire-fighting system shall be based on the
assumption that no fire-fighting equipment and no manpower for fighting fires from
outside the plant shall be available in case of a fire. A fire within the plant shall be
controlled or extinguished by the plant fire brigade using plant fire engines and plant
fire-fighting equipment and devices. The philosophy for designing the fire protection
facilities is to utilize the automatic systems and the mobile equipment, which require a
minimum number of fire fighters. Access shall be provided for fire fighting particularly for

equipment handling flammable liquefied gases or flammable products at or above auto-
ignition temperature and the seal / luboil units of rotating equipment. Some equipment
shall be protected with water spray systems to remain in operation until the fire brigade
arrives to determine the appropriate method of extinguishing attack. The quantity of
water required for fire protection shall be based on that is required to control and
possibly extinguish one major fire situation at a time under the following conditions:
Operation of deluge systems in the zone on fire (or at least 1 monitor), Operation of
deluge systems of 2 adjacent zones if (or at least 2 monitors) and 2 hydrants (or 2
monitors).
Note: For large complex units the quantity of water required for fire protection shall be
based on the Fire Hazard Analysis study and the QRA, which shall determine the “worst
case scenario”.

Detection systems shall be installed in all the relevant areas (process units and
buildings) to detect fire, smoke and gas. These shall where required, activate fire
protection systems or raise an alarm for action to be taken. Manual call point systems of
the 'break glass' type shall also be installed throughout the plant in selected positions to
raise an alarm. Indication panels shall be provided in the control room and fire station to
enable operators to take appropriate action and to indicate if a fire protection system
has been activated. Audible alarms and beacons shall be installed in process units
which shall automatically actuate on leakage of gas, or on the outbreak of a fire. Cables
for ESD solenoid valves shall be fireproofed and preferably laid in separate trays.

Passive fire protection shall be installed wherever needed on steel supports, towers,
vessels, heaters and other process equipment when subjected to severe temperature
generated by a liquid hydrocarbon or gas fire.

Positive pressure shall be maintained in the substations and a fire protection clean
agent system installed to protect the equipment against damage due to fire. Television
cameras with monitoring systems shall be installed to overlook general plant areas
enabling operators to take appropriate action when fire, smoke or gas is detected.
Around hydrocarbon production facilities, zones or spaces shall be defined in which a
gas cloud with gas concentration likely to be above the lower flammability limit (LFL) be
present when a major gas or vapor leakage occurs. These zones are called Restricted
Zones. The restricted zones concept shall be used to define preventive ignition
measures to be taken into account for the items of equipment located inside a restricted
zone, e.g. shutting down specified electrical equipment in explosive atmospheres. Hose
boxes and fire points containing portable fire-fighting equipment to be located at
strategic points adjacent to hazardous areas. Portable fire extinguishers shall be
available in those locations where rapid intervention with a relatively small fire
extinguisher may prevent a small fire from escalating. The required portable equipment
and its location shall be indicated in Fire hazard analysis which must be performed as
part of detailed design to address each potential fire hazard
This analysis should consider the following aspects:
The type of combustibles, Fire load of the hazard, Flash points, Ignition sources,
Temperature of combustibles, Combustible liquids, Flammable liquids, Exposure to
adjacent combustion, Chemicals involved, Detection, alarm, automatic control and
monitoring systems process area
