What is GSA 184B?
Form GSA 184B, Construction Progress Report (Change Order Breakdown), is the General Services Administration (GSA) form that breaks a construction contract's modifications and change orders down by number and value and records how much work and stored material on each is complete. The title printed on the form is Construction Progress Report (Modification/Change Order Breakdown).
According to the instructions printed on the back of the form, GSA Form 184B provides part of the necessary documentation on construction progress. It is not a stand-alone progress record: it covers the modification and change-order side of a contract.
The form opens with a header block: PAGE OF PAGES, REPORT NUMBER, DATE, CONTRACT NUMBER and TASK ORDER NUMBER. Below it is a table with one row per modification and five numbered columns:
- Column 1, Modification Number.
- Column 2, Total Value of Modification in the contract.
- Column 3, Value of Work Completed, split into sub-column (a), Previous Value, and sub-column (b), Current Value.
- Column 4, Value of Materials.
- Column 5, Total Value of Completed Work.
All dollar columns are marked "Dollars Only". The form carries the revision date GSA 184B (REV 10/2016).
Who needs to file GSA 184B?
GSA 184B is prepared by the contracting officer or his or her authorized representative. It is not a form that a contractor or member of the public completes on their own initiative.
The instructions say the form is used on all construction contracts awarded under new construction, repair and alteration programs, regardless of Delivery Method. If a construction contract of that kind has modifications or change orders, they are reported on this form.
The form is also tied to the contract it reports on: the header asks for the contract number and, where one exists, the task order number, so a separate report is kept for each contract or task order. The instructions name no other category of users and set out no exclusions beyond that contract scope.
When to file GSA 184B
Complete GSA 184B promptly before payment requests. The instructions say a copy of the form shall be completed promptly prior to payment requests, so each payment request on a construction contract is preceded by a current report.
The instructions also require the information on the form to be kept current. Because column 3 separates the amount completed through the previous report, in sub-column (a), from the amount completed since that report, in sub-column (b), each new report builds on the one before it, and the REPORT NUMBER and DATE in the header identify where it falls in the sequence. The form prints no separate calendar deadline.

How to submit GSA 184B
The form names no mailing address, portal or appointment process of its own. What it states is the timing and the preparer: the contracting officer or an authorized representative completes a copy promptly prior to payment requests, and the form is part of the documentation on construction progress.
- Before a payment request: complete the report so that it is current when the payment request is made.
- Where it goes: follow the contract and the contracting officer's instructions for how the report accompanies payment documentation, since the form itself prints no channel.
FillingPDF lets you fill out and download the PDF; submission follows the channels the contracting officer and the contract set.
Common mistakes to avoid
- Completing the report after a payment request instead of promptly before it, as the instructions require.
- Letting the figures go out of date; the instructions say the information on the form must be kept current.
- Entering cents in the dollar columns, which are marked "Dollars Only".
- Putting the cumulative amount through the previous report in sub-column (b) of column 3 instead of sub-column (a), or the reverse.
- Entering the value of stored materials in column 5 instead of column 4, which is for materials stored during the construction phase.
- Leaving the contract number or the task order number blank in the header when the report relates to them.
- Having someone other than the contracting officer or an authorized representative prepare the form.
