of building features, systems, equipment, and materials. Project scheduling must allow for
the early delivery of advance copies so that the required estimates can be included with the
design development submissions.
As a separate cost-saving task, the A-E's estimator must also submit a list of cost-saving
items that collectively would reduce the project's cost to at least 10 percent below budget.
The independent government estimator prepares an ECCA estimate for the base bid and
separate estimates for phased work, multistructures, and/or bid alternates or options. An overall
project ECCA estimate will also be prepared, incorporating all project segments, for analyses
or studies specified in design-programming directives and design-criteria references.
Backup worksheets are required to support the detailed estimates, which represent all
cost-sensitive project data and define all major assumptions. Backup estimating data and
quantity-survey information may be in any format, but must be grouped under appropriate
format classification headings. The Estimate Tracking Sheet and Elemental Cost Summary
forms must be submitted, including per-square-meter or square-foot calculations.

If the overall project's construction documents estimate exceeds the budget, the A-E is
again required to propose cost-saving measures to bring the project within budget, at its
own expense. To avoid over-budget construction bids, the A-E's estimator must identify at
least five construction cost-saving items, formulated as bid alternates, to bring the project's
estimate at least 10 percent below budget.
The Independent Government Estimator prepares an ECCA estimate for the base bid,
including separate estimates for phased work, multistructures, and/or bid alternates or
options with any addenda. An overall project ECCA estimate is also prepared, incorpo-
rating all project segments, for analyses or studies, as specified in design-programming
directives and design-criteria references.
ECCA estimates are developed using MasterFormat, with detailed material and labor
breakdown and appropriate subdivisions as shown in Appendix A. MasterFormat estimates
