Growth Report is required at all submissions, and a Life-Cycle Cost Analysis is required through
design development and potentially during construction documents phases for significant
items.
An independent party hired by GSA conducts a value engineering (VE) workshop, and VE is
provided in accordance with the design submissions requirements of P100. GSA may elect to
conduct an additional VE study at the construction documents phase on a project-by-project
basis.
When GSA completes an internal review of the estimate, or reconciles an independent estimate,
and at the conclusion of the VE study, a final estimate is submitted.
2 cost estimates and summaries
summary of format requirements
Table 1 in Chapter 1 displays the type of estimate to be prepared at the various design stages.
preliminary concepts
Pre-concept estimating generally requires the preparation of estimates on three competing
basic schemes/concepts, allowing GSA to select its preferred scheme.
For each scheme, the A-E's estimator prepares separate estimates for phased work,
multistructures, and or bid alternates/options. The A-E also submits estimates for concept
design analyses/studies as specified in design-programming directives and/or design-
criteria references, and a comparison sheet for multiple concepts/schemes.
concept design
These estimating requirements apply to any concept-level submission. If a project's design
requires multiple concept submissions, each concept submission must be supported by
the estimates described here.
Estimators must calculate quantities for appropriate systems or apply parameters to
appropriate building areas. Applied unit costs may be based on combined material and
labor costs. Concept estimates must match the estimate format of the budget estimate
to facilitate cost-breakdown comparisons. For prospectus work, this typically requires that
Uniformat Level 3 estimates be prepared, delineating cost-element categories shown in
