How to Fill Out and Submit GSA Form 184: Construction Progress Report

To fill out GSA Form 184, the Construction Progress Report, you work through three connected pieces: the identification header at the top, a 15-line payment calculation in the middle that ties back to your schedule of values on Form 184A and your change orders on Form 184B, and signature blocks at the bottom. The current version is dated September 2025 and is available from the GSA Forms Library.¹ The form itself is governed by FAR 52.232-5 and GSAM 552.232-5, and it does not travel alone: a certification, supporting records, and a pre-invoice meeting all sit around it. Handled correctly, the package moves through review on schedule. A wrong number or a missing attachment sends it back for correction and resets your payment clock.

Header and Identification Fields

The top of the form routes your payment request into the right contract file. A wrong contract or task order number stalls the invoice before anyone looks at the dollars.²

Report or invoice number: your sequential payment application number, kept consistent month to month.
Date: when you prepare and submit the report.
Contractor, location, and title: your company name, the site address, and the official project title from the contract.
Contract number and task order number: copied exactly from the contract documents. Task order numbers apply to indefinite-delivery contracts.
Completion dates: four separate fields covering the initial contract completion date, the revised date if modifications changed it, your estimated substantial completion date, and the actual substantial completion date (filled in only when reached).
Percent completed: two figures, your cumulative percent complete through this reporting period and the “normal to date” baseline showing where the original schedule said you should be.
Average work force: the number of workers on site during the period.
Progress indicators: three yes/no checkboxes for whether material delivery, construction equipment, and shop drawing submissions are satisfactory.

At the bottom, signature blocks cover the preparer, the person who accepted the work, and two approval signatures. On most GSA projects the Contracting Officer or their representative signs the acceptance and approval lines after reviewing what you submitted.

Working Through the 15-Line Payment Calculation

The financial core of the form is a 15-line calculation that starts at the total contract value and works down to the net amount due this period. Every figure has to trace to your schedule of values and to actual site progress, not to projections of what you expect to finish by month’s end.³

Line 1, initial contract amount, split across three sub-lines: design phase and pre-construction services, bonds, and construction services.
Line 2, contract modifications and change orders, pulled from GSA Form 184B, which tracks each modification separately.
Line 3, options exercised, if the government has exercised options for additional design or construction phases.
Line 4, total contract amount to date, the sum of Lines 1, 2, and 3, and your current contract ceiling.
Line 5, value of work completed to date, cumulative, drawn from your detailed breakdown on GSA Form 184A.
Line 6, value of work completed under modifications, taken from Form 184B.
Line 7, value of material, with sub-lines for material stored on site and material in off-site storage.
Line 8, total value of completed work and material, the sum of Lines 5, 6, and 7.
Line 9, less retainage and withholdings.
Lines 10 through 14, subtotals, previous and current bond premiums, and a deduction for payments already received.
Line 15, amount of payment this report, the net figure you are requesting.

Percentages on the 184A attachment need to match what an inspector walking the site would see. If you claim 80 percent on mechanical rough-in and the ductwork is visibly incomplete, the Contracting Officer will reduce or reject the estimate. FAR 52.232-5 requires progress payments to be based on work that “meets the standards of quality established under the contract, as approved by the Contracting Officer.”³

Claiming Materials on Line 7

Line 7 lets you request partial payment for material that has been delivered but not yet installed. For material on site, the Contracting Officer has broad authority to include delivered materials and preparatory work in the payment estimate. For material stored off site, two conditions apply: the contract must specifically authorize off-site storage payments, and you must provide evidence that you hold title to the material and intend to use it on the project.³ A paid vendor invoice is the most direct proof of title. Some Contracting Officers also want off-site material stored in reasonable proximity to the site, accounted for in a fixed location rather than in transit, and protected from deterioration or damage.

Pre-Invoice Meeting and the Required Certification

Before you submit, GSAM 552.232-5 requires you to attend a pre-invoice payment meeting with the government’s designated representative unless the Contracting Officer directs otherwise. The meeting walks through the upcoming invoice so both sides agree on quantities and percentages before the paperwork goes in. Bring documentation that supports the amounts you plan to request.⁴

GSA Form 2419 (Certification of Progress Payments Under Fixed-Price Construction Contracts) accompanies every progress payment request alongside Form 184.⁴ At the end of the project, GSA Form 1142 (Release of Claims) is required before final payment can be issued, along with warranties, as-built drawings, and operating manuals.

Supporting Documents That Go With the Form

The report itself is only part of the submission. Several supplemental records substantiate the numbers on Form 184.

Site Photographs

Photos are the first line of defense if a completion percentage is questioned. Take high-resolution images that show the milestones reached in each trade during the billing period, and label them by date, location within the building, and the corresponding schedule-of-values line item. Ambiguous or poorly lit photos create more questions than they answer.

Updated Construction Schedule

Most GSA contracts require a detailed logic-based schedule, typically a critical path method schedule, showing how current progress affects the projected completion date. If a delay hit during the period, document the cause and the recovery steps you are taking. Submitting the report without an updated schedule gives the Contracting Officer a reason to hold retainage or withhold payment.

Daily Activity Logs and Certified Payroll

Daily logs record workers on site, hours worked, equipment in use, and weather or site conditions that affected productivity. They support your progress claims and feed the certified payroll records required by the Davis-Bacon Act. On federally funded construction, contractors must pay prevailing wages and submit weekly certified payroll records to the contracting agency.⁵

Subcontractor Payment Data

FAR 52.232-5 requires the payment request to include an itemization of amounts related to each element of work, along with amounts included for each subcontractor, total subcontract values, and amounts previously paid to each sub.³ Assembling this before you fill in the form speeds up review.

Submitting the Package Through Kahua

GSA’s enterprise project management platform is Kahua. It replaced the older electronic project management systems and is now required for all contractors and GSA employees working on projects in federally owned or leased space.⁶ Upload Form 184, the 184A and 184B attachments, Form 2419, photographs, the schedule update, and payroll records into the project file. Kahua logs the submission date, which matters for calculating your payment deadline.

GSAM 552.232-5 directs you to submit invoices to the Contracting Officer unless told otherwise. If the Contracting Officer disputes part of the requested amount, the government may pay the undisputed portion and return the rest for correction.⁴ Submit separate payment requests for progress payments, retainage releases, and partial or final payments. Do not combine them into a single invoice.

Retainage on Line 9

Retainage on federal construction contracts works differently than on many private projects, and that shapes what belongs on Line 9. If the Contracting Officer determines you made satisfactory progress during the billing period, the full payment is authorized with no retainage at all. Retainage only applies when progress is unsatisfactory, and even then the maximum the government can withhold is 10 percent of the payment amount.³

Once the project reaches substantial completion, the Contracting Officer may keep only what is considered adequate to protect the government’s interest and must release the rest. When a separately priced building or division is completed and accepted, payment for that portion is made without any percentage retained.³ Disagreements over the Line 9 number should be raised at the pre-invoice meeting, not after submission.

When You’ll Get Paid

The Prompt Payment Act sets deadlines for government payments. On construction progress payments, interest penalties begin to accrue if an approved payment request remains unpaid more than 14 days after the agency receives it. Some solicitations specify a longer period when the government needs extra inspection time, but 14 days is the default.⁷

If the Contracting Officer determines your invoice is not a proper invoice, the agency must return it as soon as practicable and no later than seven days after receipt, with an explanation of what needs to be corrected. The interest clock does not start until a corrected proper invoice is received, so an error on Form 184 effectively resets your payment timeline.⁷

After you receive payment, federal regulations require prime contractors to pay subcontractors for satisfactory performance no later than seven days after receiving the government’s payment.

The Cost of Overstating Percentages

Inflating completion percentages or fabricating quantities on Form 184 triggers the federal False Claims Act. A person who knowingly submits a false claim is liable for three times the government’s damages plus a per-claim civil penalty.⁸ Under FAR 9.406-2, a contractor’s knowing failure to disclose credible evidence of a False Claims Act violation is an independent cause for debarment from federal contracting.⁹ Report what your photos, logs, and subcontractor records can prove. If a percentage is genuinely uncertain, raise it at the pre-invoice meeting rather than rounding up.
