GSA Form 2631: Architect-Engineer Cost Estimate Summary
GSA Form 2631, Architect-Engineer Cost Estimate Summary, is a General Services Administration form. Its footer reads GSA 2631 (REV. 9/2014), and GSA hosts it in its forms library. The form page is headed Architect - Engineer Cost Estimate, Basic Services (See Instructions), and the instructional guidance printed with it names it GSA Form 2631, Architect Engineer Cost Estimate Summaries.
The guidance says the fee proposal and the cost estimate are both summarized on Form 2631, which reports costs for each project phase as basic services or excluded services. It is used with GSA Form 2630, Architect Engineer Cost Estimates. The guidance says the forms help PBS ensure contract awards for Architect-Engineer services fall within the statutory limits of Public Law 92-582, the Brooks Act, and quotes the 6 percent limit in FAR Part 15.404-4(c)(4)(i)(B). Table One, printed at the end, sorts services into basic and excluded services.

Questions about Form GSA2631
Who issues GSA Form 2631?
The footer names the General Services Administration and reads GSA 2631 (REV. 9/2014). The guidance printed with it is addressed to PBS acquisition, contractor and program offices. GSA hosts the form in its forms library.
How is GSA Form 2631 different from GSA Form 2630?
The guidance says GSA Form 2630 is used by the Prime Contractor and all Sub Consultants to estimate each phase of the work, while GSA Form 2631 summarizes, per project phase, all cost proposed or estimated for the work in the contract statement of work.
What are basic and excluded services?
The guidance says Table One, PBS Application of the 6% Statutory AE Design Fee Limitation, defines which services are Basic Service or Excluded Services. Its notes say special consultant services specifically applied to the actual preparation of drawings or specifications are Basic Services within the 6% limitation.
Does the 6% limitation apply to every A-E contract?
The notes to Table One say the 6% limitation only applies to contracts for complete design services and does not apply to AE contracts for the preparation of performance specification or bridging documents for design build contracts.
How is profit shown on the form?
The guidance says profit cannot be set by simply applying a predetermined percentage to the total estimated cost. It is established as a dollar amount after considering risk, the nature of the work, joint venture responsibilities, the A-E's investment, subcontracting and other criteria discussed in GSAM.
Who signs GSA Form 2631?
The form prints a Prepared By signature and date and an Approved By signature and date. The guidance says the form is completed by the Architect Engineer and the GSA Estimator.
