1.3.2.  Architect-Engineers (A-E) Estimates.

Because of the use and far-reaching impact of their estimates, A-E firms must provide comprehensive and up-to-date estimates for projects they design for the government. Using the latest computerized estimating programs and technology and commercial pricing guides, they are fully equipped to prepare accurate cost estimates for their designs. Designers must be aware of the relative economics of different types of structures and materials and must keep pace with changing trends in building costs. However, before relying on an estimate for budgetary or price analysis purposes, the estimate should be updated to include any adjustment for escalation of prices, and for any design changes (both additions and deletions) injected by the government since receipt of the initial 100% design package. This is especially important when dealing with an older design. You may discover, after-the-fact that facility occupants or requirements have changed without a commensurate adjustment to the project cost estimate.
