Highways Infrastructure Assets
Refer to the L Pack guidance and the WGA timetable paper "Accounting for Highways Infrastructure Assets in the Local Authority Sector on a Depreciated Replacement
Costs Basis: Interim Accounting Arrangements for the Period up to 2012-13". This paper is available on the WGA page of the HM Treasury; DCLG; Scottish Government;
and Welsh Assembly Government websites, and is based on the decisions made by the CIPFA Project Implementation Steering Group (PISG).
The original timetable required an audit review of GRC data in the 2010-11 Return. However, given the resources and cost involved in auditing the data in this era of
substantially tighter public spending, the first audit review has been delayed until the more complete and full dry run year, 2011-12. This should not detract from the worth of
the Highways Infrastructure work and the improved services and efficiency savings that will result. We stress the importance of providing the data below to the same quality
that would have been given had the audit review been going ahead, given the size and complexity of the task, and so that the momentum of the work is maintained.
All estimates should be calculated on the basis set out in the CIPFA Code of Practice on Transport Infrastructure Assets - Guidance to Support Asset Management,
Financial Management and Reporting (published March 2010).

This is for information purposes only, and is to capture the progress being made by local authorities on revaluing their Highways Infrastructure Assets for Gross
Replacement Cost (GRC) and Depreciated Replacement Cost (DRC). Please be aware that in many cases local authority staff outside of the central finance team, such as
asset management and engineering staff, are undertaking this work.

Please respond to the questions in respect of the CIPFA Code of Practice on Transport Infrastructure Assets and supporting materials below, using a scale of 1 to 5 as
1 = Strongly Disagree; 2 = Disagree; 3 = Neither agree nor disagree; 4 = Agree; 5 = Strongly Agree
Answer 1 to 5
1. The tools to support the implementation of the Code are helpful and appropriate.
2. All those who ‘need to know’ at this authority are aware of the Code and its requirements
and implications, including senior management, finance practitioners and asset
3. The financial and technical practitioners are clear about their roles and work together to
produce the required information.
4. This authority is actively working with other authorities in a regional group (or similar) to
support and benchmark our work on asset valuation and implementing the Code.
5. This authority will be able to fully implement the Code to the published timescales including
a full, audited dry run in 2011-12 and full implementation in 2012-13.
6. This authority has sufficient, appropriate and robust inventory data to implement the Code
on the following assets:
• Footways & Cycletracks
• Traffic Management
7. For the areas in question 6 where appropriate inventory data is not yet available, this
authority is confident that plans are in place to gather this data and it will be available
to fully implement the Code to the published timescales.
8. This authority has sufficient, appropriate and robust condition or age data (as appropriate)
to implement the Code on the following assets:
• Footways & Cycletracks
• Traffic Management
9. For the areas in question 8 where appropriate condition or age data is not yet available, this
authority is confident that plans are in place to gather this data and it will be available to fully
implement the Code to the published timescales.
10. This authority has a fully developed and implemented TAMP/ HAMP.
11. Are there any further issues arising from the Code or where more detailed guidance or exemplification would be helpful?

Carriageway and Footway Gross Replacement Cost (GRC)
to be used where footway extents are not assessed separately from carriageways
Notes for users
The spreadsheet uses HAMFIG default rates and widths, by inserting lengths of carriageway from your inventory the GRC is calculated
1. The R199B lengths should be inserted into the yellow boxes
If a known length of dual carriageways is included within the R199B length - add this length to the R199B length to allow for the second carriageway
Notice for compilers - ONLY use this sheet if FOOTWAY extents are
Any lengths of detrunked 'A' roads, which are not included within the R199B figures, should be added.
2. The HAMFIG default values for the GRC rates should not be varied.
3. The HAMFIG default values for widths may be altered if good, traceable, inventory data is available.
4. The rates are for a complete construction
Carriageways - include all elements associated with the area of the carriageway and an allowance for footways associated with the road hierarchy
Carriageway unit rates are composed with an allowance for slip roads, roundabouts and other such features and therefore fully inclusive
Linear items - include for kerbs, drainage, line marking etc associated with that road hierarchy - refer to Code for full list (Note this is different to Street Furniture)
(Note that Linear Items are a different category to Street Furniture; Linear Items are calculated on this sheet and reported as part of the CW GRC whereas
Street Furniture is a different asset type, calculated separately and included as a separate line on the Lpack return)
5. Fees for design; supervision and other costs associated with the construction element are included within the HAMFIG default rates
6. The GRC figure calculated is adjusted by selecting the 'Regional Factor' from the drop-down list.
Using This Sheet
First a reminder:
This is the sheet to use if you don't have good footway inventory. This sheet uses you carriageway inventory to produce an estimated footway value.
This is the last year when this option will be available; in future years you will need to provide your own footway inventory information as defaults are withdrawn
Go to the 'Carriageway incl footway' tab
Step 1 Enter your R199b information with appropriate adjustments into the yellow cells in Column C
Step 2 Select your region in the Yellow cell that says 'Pick your region'
Step 3 The spreadsheet will automatically calculate your carriageway and footway GRC values these are displayed in the Summary box and automatically populated on the 'Add info - Hways Infr' tab
Note that Land unit rates and calculations are not provided in this spreadsheet. We are hoping to make these available soon but work is still in progress on this at the time of publication
HAMFIG will give further guidance on the use of the Land values as and when centrally provided rates are available
In the event that centrally provided rates are not available in time to support this year's WGA returns, you may either make local estimates of Land value or provide a 'null return' for this
Tip: You MUST include a value in all yellow cells on this sheet
Tip: You CAN change values in the blue cells IF you have good robust carriageway average width values for your network; otherwise you should continue to use the defaults provided
Tip: You CANNOT change other cells on this sheet.
Go to the 'Add info - Hways Infr' tab
Note - this tab is a copy of the appropriate data entry sheet from this year's L Pack - the information request that HM Treasury will have sent to all LA finance departments asking for
Whole of Government Accounts information. This tab is designed to look exactly like the L Pack sheet so that information can be transferred from one to the other in the right format
to help eliminate some of the reporting errors that crept in last year.
Step 5 Transfer the information on this tab exactly as it appears to the appropriate sheet in the L Pack.
Tip: You may choose to populate the rest of the data (structures, land etc) on this sheet or, if calculated elsewhere, you can put it straight into the L Pack
Tip: If you are a highways team preparing returns to pass to your finance colleagues, you may find it easiest to fully populate this sheet, including the answers to the CIPFA questionnaire,
and pass the whole thing to your finance team for inclusion in the WGA returns. However you do it, engineering and finance staff should work together on this process.
Tip: The Carriageway and Footway figures are automatically populated on to this tab but the other values such as structures and land must be entered manually

Version 1c - Published April 2011 - first published version of the 10/11 sheet. Filename 2010-11 Cway incl Fway v1 rev9.xls
Version 1.1c - Published 3rd May 2011 - corrected error in one default width on v1. Filename 2010-11 Cway incl Fway v1 rev10.xls
Note this is Version 1.1c (Combinied) to distinguish it from Version 1.1s (for 'Separate'), the difference being the way in which the footways are handled, as described above.
