The FAR 52.236-1 self-performance requirement obligates the prime contractor on a fixed-price federal construction contract expected to exceed $2 million to build a set minimum percentage of the work, on site, with its own organization. The contracting officer writes that percentage into the clause before the solicitation goes out. The regulatory floor is ordinarily 12%, and it is often set higher. Miss it, and the government can issue cure notices, halt the job, and terminate for default.1Acquisition.GOV. 48 CFR 52.236-1 – Performance of Work by the Contractor
When the Clause Is In Your Contract
Contracting officers are required to include FAR 52.236-1 in solicitations and contracts for fixed-price construction expected to exceed $2 million. Below that dollar threshold, inclusion is optional.2Acquisition.GOV. 48 CFR 36.501 – Performance of Work by the Contractor
One boundary matters up front. The clause does not apply to contracts awarded under small business set-aside programs, including those under FAR subparts 19.5, 19.8, 19.13, 19.14, and 19.15. Set-aside construction work is governed instead by the limitations on subcontracting at FAR 52.219-14, which uses a different calculation entirely.2Acquisition.GOV. 48 CFR 36.501 – Performance of Work by the Contractor If you are bidding a set-aside, the number in your 52.236-1 clause is not the number that controls you.
How the Percentage Is Set
The clause contains a fill-in blank. FAR 36.501(a) directs the contracting officer to set the required percentage as high as the project warrants, weighing complexity and the amount of specialty subcontracting that is customary or necessary. The ordinary floor is 12%, and individual agencies or contracting officers can require more.2Acquisition.GOV. 48 CFR 36.501 – Performance of Work by the Contractor
Specialty trades that are typically subcontracted, such as plumbing, electrical, and HVAC, should not normally factor into the contracting officer’s decision about what percentage to demand.2Acquisition.GOV. 48 CFR 36.501 – Performance of Work by the Contractor The number is calibrated to the core work a prime is expected to handle directly, not to the full trade stack on the job.
What “Own Organization” Means
The clause requires performance “on the site, and with its own organization.”1Acquisition.GOV. 48 CFR 52.236-1 – Performance of Work by the Contractor The regulation does not carry a standalone definition, but the practical test is the payroll. Workers on the prime contractor’s direct payroll, supervised by the contractor’s own field leadership, count. Anyone not on that payroll is doing subcontracted work for purposes of the calculation.
That has real consequences. Labor you bring in as independent contractors rather than employees does not count toward self-performance. Neither does any tier of subcontracted labor, whether it is a first-tier mechanical sub or a lower-tier specialty firm that sub brought on. The employment relationship controls, not who happens to be directing the crew on the ground that day.
How You Calculate the Percentage
The self-performance percentage is a fraction. The denominator is the total cost of all work to be performed under the contract, covering direct construction costs for both the prime and every subcontractor: labor, materials, equipment, and jobsite overhead across the entire project.1Acquisition.GOV. 48 CFR 52.236-1 – Performance of Work by the Contractor
The numerator is what the prime’s own employees actually build: labor by payroll workers, equipment the contractor owns or rents and operates with its own crew, and materials the contractor purchases and installs with its own forces. Direct physical construction work is what counts, whether at the project site or at an off-site facility tied to the project.
Certain costs come out of both sides of the fraction so they do not skew the ratio. Excluded are the prime’s executive, administrative, and clerical staff costs, its profit, its general overhead, and the cost of performance and payment bonds. The calculation is meant to isolate the direct cost of physically building the project, so back-office and financial line items drop out.
Asking to Lower the Percentage After Award
The percentage is not permanent. If circumstances change once work is underway, you can ask the contracting officer to reduce it through a supplemental agreement. The officer can agree, but only if the reduction benefits the government.1Acquisition.GOV. 48 CFR 52.236-1 – Performance of Work by the Contractor
Two things to keep in mind. The clause conditions the request on it occurring “during performing the work,” so you cannot negotiate the number down before the job starts. And there is no appeal built into the clause and no presumption in your favor. A request that succeeds is one that gives the contracting officer a concrete reason, such as schedule acceleration, access to a better-qualified specialty firm, or cost savings, to conclude the government comes out ahead.
What Happens If You Fall Short
Missing the self-performance threshold is a breach. How the government responds usually tracks how far below the number you are and whether the shortfall can still be corrected.
Cure Notices and Show-Cause Notices
Before terminating for default, the government generally must give notice and an opportunity to fix the problem. A cure notice gives you at least 10 days to remedy the deficiency. If fewer than 10 days remain in the contract schedule, the government may instead issue a show-cause notice asking you to explain in writing within 10 days why the contract should not be terminated.3Acquisition.GOV. 48 CFR 49.607 – Delinquency Notices Assistance the government offers during this window is aimed at reducing damages and does not waive any of its contract rights.
Stop-Work Orders
The contracting officer can also direct you to halt all or part of the work for up to 90 days. You must comply immediately and take reasonable steps to minimize costs during the stoppage. The government then decides whether to cancel the order and let work resume or to terminate.4Acquisition.GOV. 48 CFR 52.242-15 – Stop-Work Order
Default Termination
The worst outcome is termination for default under FAR 52.249-10. When a contractor fails to prosecute the work with adequate diligence, the government can terminate the right to proceed, take over the site including materials and equipment, and complete the project itself or through a replacement contractor. The defaulted contractor and its sureties are liable for the increased costs of finishing the job.5eCFR. 48 CFR 52.249-10 – Default Fixed-Price Construction A default termination is also recorded in the Contractor Performance Assessment Reporting System, the federal database used to evaluate contractor reliability, and that record can effectively lock a firm out of future federal work for years.
Other Consequences
The government may suspend or reduce progress payments where you fail to comply with material contract requirements. Contracting officers must also prepare past performance evaluations at least annually and at contract completion, and those evaluations follow you into future competitions.6Acquisition.GOV. 48 CFR 42.1502 – Policy Where the contract includes liquidated damages, the government can assess those as well.
