FAR 52.236-1 Self-Performance: Bid-Day Checklist for Contractors
On federal construction projects, prime contractors cannot simply broker out the entire scope of work to trade subcontractors. Solicitations routinely incorporate federal contract clauses governing how much work the prime contractor must handle directly. Estimators, general contractors, and trade subcontractors reviewing federal bid documents must evaluate the exact self-performance requirements to assemble compliant estimates before the bid deadline.
Checklist Step 1: Identify the Inserted Self-Performance Percentage
When federal contracting agencies issue construction solicitations, the contracting officer includes specific language regarding work distribution. Under FAR 52.236-1 Performance of Work by the Contractor, the contracting officer must complete the clause by inserting the appropriate percentage in the blank space provided in the solicitation.
On bid day, review the solicitation documents to confirm the exact percentage specified in the clause text:
- Confirm the inserted percentage written in words followed by numerals in parentheses within the clause.
- Verify the baseline under prescription 36.501(b), which directs the insertion of the clause into federal solicitations.
- Review the solicitation terms to ensure the percentage matches the complexity and magnitude of the project.
- Check how customary or necessary specialty subcontracting under 36.501(a) factors into the remaining non-performed scope.
Because the government tailors this figure per solicitation, estimators must never rely on assumed percentages from past projects.
Checklist Step 2: Confirm Site Location and Direct Workforce Boundaries
The clause establishes explicit parameters around where and by whom the work must be executed. According to FAR 52.236-1, the contractor shall perform the work on the site and with its own organization. Estimators must separate on-site labor from off-site support or supplier deliveries when determining what counts toward the self-performance minimum.
During the bid compilation process, review your internal crew allocations against the total contract value. The percentage applies to the total amount of work to be performed under the contract. Work completed by lower-tier specialty trades, equipment vendors, or off-site fabricators cannot be counted toward the prime contractor's own organization requirements. If your firm plans to self-perform interior partitions, drywall, or framing, confirm that the direct craft labor and supervision are directly employed on the project site by your organization.
Checklist Step 3: Align Specialty Trade Packages and Bid Leveling
Trade subcontractors, such as drywall and acoustic ceiling installers, need to understand how the prime contractor's self-performance obligations impact subcontract scopes. When a general contractor must satisfy a high self-performance threshold, they may choose to self-perform key trades such as metal framing, drywall hanging, or general trades, while subcontracting out mechanical, electrical, or specialty finishes.
Estimators should review our Bid Day Checklist for Drywall and Ceiling Subcontractors and use systematic processes to level subcontractor bids across trade packages. If specialty trades carry scope that the prime intends to self-perform to meet the contract percentage, bid leveling prevents overlapping scopes, missing tasks, or misallocated labor costs.
Checklist Step 4: Review Requirements for Post-Award Percentage Reductions
Bid estimators and project managers must also account for what happens if project conditions change after contract award. FAR 52.236-1 includes explicit rules governing whether the self-performance percentage can be altered during construction.
The clause states that the percentage may be reduced by a supplemental agreement to the contract under two conditions:
- The contractor must formally request a reduction during the performance of the work.
- The contracting officer must determine that the proposed reduction would be to the advantage of the government.
A contractor cannot unilaterally decide to subcontract additional scopes if field labor shortages arise. Because an adjustment requires a formal supplemental agreement approved by the contracting officer, estimators must verify on bid day that the firm has the field capacity to meet the inserted percentage from day one.
Checklist Step 5: Final Bid-Day Math and Verification
Before releasing your final bid proposal, run through a final calculation check to ensure compliance with the clause terms:
- Calculate the total dollar amount of the contract work across all divisions.
- Multiply the total contract amount by the inserted percentage designated under FAR 52.236-1.
- Total all direct costs for work performed on the site with your own organization.
- Confirm that the prime organization's on-site work equals or exceeds the required percentage threshold before executing the bid submission.
