general philosophy
The Federal Acquisition Regulation (FAR) 36.203 requires that every Government estimate be
prepared as though the Government were competing for the award. Therefore, all costs that a
prudent and experienced contractor would incur must be included in project cost estimates.
A listing of known facts, construction tasks, and supplemental judgments form the basis of the
estimate at each stage of design. This provides a realistic approach to estimating, and it creates a
history of project cost development.
P100, Facilities Standards for the Public Buildings Service, lists the estimating deliverable
requirements for each design phase, but they are clarified here.
