4 cost growth report
GSA uses the Cost Growth Report (CGR) to track cost growth at each design phase by
comparison with the project budget. This is done by comparing the prior submission's Uniformat
Level 2 costs for each cost element with the current submission's Level 2 costs, and identifying
the cause of large variances. The A-E's estimator prepares this report for each design-phase
submission, using GSA Form 3474, Project Cost Comparison Summary. See Appendix B: Estimate
Tracking Sheets for a sample of the form.
preliminary concept design
Each design concept considered during this submission must be within the project's overall
construction budget. The A-E will be required to redesign any concept design scheme not
within the budget to bring it within budget constraints at its own expense.
For each concept scheme, the A-E's estimator lists cost-saving ideas that collectively will
bring project costs within budget. The Independent Government Estimator validates these
cost-saving measures by preparing an order of magnitude estimate of savings for each of the
A-E's proposed measures. The A-E submits its Cost Growth Report on GSA Form 3474.
final concept design, design development, and construction documents
If the estimates for the concept design and design development submissions exceed the
project budget, the A-E is required, at its own expense, to propose cost-saving measures
to bring the project within budget. Just as described above for the preliminary concept
design's CGR, the A-E summarizes the final concept design estimate on GSA Form 3474
and compares it to the project budget. This report is supported with cost estimates for each
proposed cost-saving item. The independent government estimator validates these cost-
saving measures as outlined in the paragraph above for the preliminary concept design
If the estimate for 90% construction documents exceeds the project budget, the A-E is
required to propose cost reductions in the form of bid alternates sufficient to ensure receipt
of bids within budget on the scheduled bid date. The Independent Government Estimator
validates these cost-saving measures, as indicated in the paragraph above, for the concept
design and design development submissions.
