General notes

a. Accepted alternative terms are separated with a vertical slash ( | ). Bullet points under Cost Sub-Groups serve to illustrate the scope but without limitation

b. In the case of projects where there are sub-projects, allocate costs to their most relevant Sub-Project, Cost Group and Cost Sub-Group as far as possible without omissions or duplications. Add a separate Sub-Project called 'Common' to capture costs that are common to all or most Sub-Projects and which should better be shown separately to permit reallocation in the appropriate way when the specific need arises.

c. Add a Cost Sub-Group 'All Other Costs' within the relevant Cost Group to take account of the costs of those Cost Sub-Groups whose value is insufficient to warrant a separate Cost Sub-Group (typically whose value is less than 5% of the relevant Cost Group). The Cost Code should end with '.999'.

d. All costs should represent those payable by the Client and include the payees' overheads and profits where applicable.

e. Include design fees payable by the Constructor under Construction | Renewal | Maintenance Costs.

f. Group costs of preparatory or enabling work with the principal items they are serving.

g. Group costs of ancillary items, such as temporary lateral supports/temporary drainage/dewatering/slope treatment and protection for earthwork, falsework/formwork/reinforcement for concrete work, ironmongery/hardware, fixing accessories, inline fittings for pipes/drains/conduits/cables, painting/coating, etc. with their principal items unless otherwise shown as a Cost Sub-Group. Group costs of testing and commissioning with the relevant services.

h. Round off costs suitably and commensurate with the accuracy of the amounts.

i. State 'Excluded' if the cost exists but is not reported. State 'N/A' (not applicable) if the cost does not exist.

j. Apportion the costs of cost code [2 | 3 | 5].08-[2 | 3 | 5].10 into cost code [2 | 3 | 5].01-[2 | 3 | 5].07 in case of simplified presentation.

k. As the Project develops, the Risk Allowances under cost code [2 | 3 | 5].09 may be gradually expended and the expended costs would be reflected in the costs of other items. The allowances may be explicitly shown in the Constructor's contract sum build-up or reserved in the Client's own budget not known to the Constructor. For cost reports on actual costs after construction, any surplus allowances should not be included.

l. The 'Design development allowance' under cost code [2 | 3 | 5].09 is an allowance in a pre-construction forecast estimate or cost plan for unforeseen extra costs due to the development of the design as it evolves. Once the design is complete, this allowance should become zero.

m. The 'Construction contingencies' under cost code [2 | 3 | 5].09 is an allowance for unforeseen extra costs during construction. Typically, it is to cover unforeseen events after awarding a construction contract. After the completion of the final account for the construction contract, this allowance should become zero.

n. Typically, a pre-construction cost estimate may be prepared based on the price level at a certain date, which may be current at the time of preparing the estimate or at an earlier base date, with or without allowance for the possible increases or decreases due to inflation or deflation during construction. A construction contract may be priced based on the price levels at a certain Base Date around the time of tendering and permit adjustments for rises or falls in the costs during construction. A provisional allowance should be made inside or outside the contract for the possible increase or decrease and should gradually be replaced with the actual outcome. The 'Price Level Adjustments under cost code [2 | 3 | 5].09 are to allow for the aforesaid possible change until the time of tendering, and further change during construction.

Appendix G - Reporting Templates

Specific notes for Appendix G

  • Project Attributes and Project Values are not shown in this example but should be provided in the actual cost report.
  • '$M' = $ million.

Mixed project - Grand Summary

    • All costs are brought to the Common Date, which is assumed to be not earlier than the completion of construction.
    • Whether the payments at the time of payment are based on Real Costs or Nominal Costs should be stated. The discounting factors should take that into account.

 

A Building project - Construction Costs only

  • Columns for the unit cost calculated using additional project quantities may be added if required.

A project - Total Capital Cost

A project - Life Cycle Costs

 

 

Comparison between two design schemes

  • Additional columns may be added as appropriate.

Project with Sub-Projects

  • Additional columns for other Sub-Projects may be added as appropriate.
  • A set of columns for 'Common' may be added before the 'Total' to show the costs that may be spread across all or most Sub-Projects. These costs may be shown separately to permit reallocation in the appropriate way when the need arises.

A project - Construction Costs only, involving two currencies

  • Additional column may be added to show the conversion date.

A project - Construction Costs only, involving many currencies

  • Additional column may be added to show the conversion date.

Appendix I - Interface with International Property Measurement Standards (IPMS)

Measurement of Floor Areas for Buildings for ICMS Cost Reports

The various cost analysis standards worldwide require the measurement of a gross floor area (either external (GEFA) or internal (GIFA)) or similar variations thereof to permit the representation of overall costs in terms of currency per floor area. However, even though the use of these terms is commonly understood, the definitions and interpretations of these terms are also subject to considerable regional variations. Measurement guidelines and definitions vary considerably between countries. Linking ICMS with IPMS provides a valuable tool for overcoming these inconsistencies. ICMS require a cost report to include both GEFA (IPMS 1) and GIFA (IPMS 2) measured in accordance with the rules set out in IPMS. IPMS are evolving on a building-sector basis (offices, residential, retail, etc.). These rules are summarised below, but reference to the specific Standards, for the building type, is recommended.
