5. Details of any materials to be used by the contractor in support of the change should be provided with the associated cost. Project staff should review these costs to establish if they are reasonable for the work to be undertaken. This can be done by a number of methods:
• through CAAS where they have been asked to undertake a price investigation (they may also be able to provide general advice in certain circumstances);
• benchmarking to similar work undertaken on the contract in question or others across the acquisition team;
• by reference to information in the public domain such as catalogues.
Note: See paragraph 4, above, regarding the provision of a statement by acquisition team members that the hours and materials are fair and reasonable for the task.
