Authoritative Guidance Summary

Where it is not possible to agree a fixed price or other incentive pricing arrangement, either at the outset or during the course of the contract, the contract may be placed on the basis that the contractor will be paid the costs reasonably and properly incurred by him in carrying out the work plus a sum for profit - 'cost-plus'. Such arrangements should only be used exceptionally and where project progress/performance supported by Earned Value Management data.

Contracts priced on the basis of ascertained costs should normally include

Acquisition teams must exercise careful judgement on the size of terminal retentions pending final settlement, not only as a safeguard against over-payment on `interims' but also as an incentive for finalisation.

Acquisition teams should monitor the contractor's activities closely and consider reducing appropriately the level of progress and final payments to the contractor, where necessary to rectify unsatisfactory performance (using Earned Value Management (EVM) data as evidence), unreasonable expenditure or failure to submit Cost Certificate and Summary Cost Statements when required.

Certified cost statements are to be referred to the Cost Assurance and Analysis Service (CAAS) (formerly known as Cost Assurance Service (CAS)) within two weeks of receipt for selective investigation.

Final prices may be agreed including estimated costs, direct and/or indirect, where these relate to a small proportion of the overall contract price with appropriate `rounding' of the costs if necessary, unless there are special reasons why this should not be done.
