FAR 52.246-12—Inspection of Construction.
Plain-English Summary
FAR 52.246-12, Inspection of Construction, sets the inspection and quality-control framework for construction contracts. It covers the definition of “work,” the contractor’s duty to maintain an adequate inspection system and records, the Government’s right to inspect and test before acceptance, and the limits of those inspections. It also explains that Government inspection does not relieve the contractor of responsibility for quality, loss, or contract compliance, and that inspectors cannot change contract terms without written contracting officer authorization. The clause addresses contractor support for inspections and tests, including furnishing facilities, labor, and materials, and it allows the Government to charge the contractor for extra inspection costs caused by the contractor’s failure to have work ready or by the need for reinspection or retesting. It further covers correction or replacement of nonconforming work, Government remedies if the contractor does not promptly correct defects, the special rule for uncovering or tearing out completed work for examination, equitable adjustments when the work proves compliant, and final acceptance of completed work. In practice, this clause is central to construction contract administration because it defines how quality is checked, who bears the cost of defects, when the Government may require rework, and when acceptance becomes final except for limited post-acceptance rights such as latent defects, fraud, gross mistakes amounting to fraud, and warranty or guarantee claims.
Key Rules
Work includes all components
“Work” is defined broadly to include materials, workmanship, and the manufacture and fabrication of components. This means the inspection obligation covers not just the finished structure, but also the inputs and processes used to produce it.
Contractor must maintain quality control
The contractor must maintain an adequate inspection system and perform inspections sufficient to ensure contract compliance. Complete inspection records must be kept and made available to the Government.
Government inspection rights are broad
The Government may inspect and test at all places and at all reasonable times before acceptance to ensure strict compliance with the contract. These inspections are for the Government’s benefit and do not replace the contractor’s own quality responsibilities.
Inspection does not equal acceptance
Government inspections and tests do not relieve the contractor of responsibility for quality, loss or damage before acceptance, or continuing Government rights after acceptance. The presence of a Government inspector also does not waive any contract requirement.
Inspectors cannot change the contract
A Government inspector has no authority to alter specifications or other contract terms unless the contracting officer gives written authorization. Contractors should treat any informal direction from an inspector as nonbinding unless properly issued.
Contractor must support inspections
The contractor must provide, at no increase in contract price, the facilities, labor, and material reasonably needed for safe and convenient inspections and tests. Special, full-size, and performance tests must be conducted as the contract requires.
Government may charge extra inspection costs
If work is not ready when the contractor says it will be ready, or if prior rejection requires reinspection or retesting, the Government may charge the contractor the additional inspection or test costs. The Government must still conduct inspections in a way that does not unnecessarily delay the work.
Nonconforming work must be corrected or replaced
The contractor must promptly replace or correct work that does not conform to contract requirements, at no additional cost, unless the Government decides it is in the public interest to accept the work with an equitable price adjustment. Rejected material must be segregated and removed promptly.
Government remedies for failure to correct
If the contractor does not promptly correct rejected work, the Government may correct or replace the work itself and charge the cost to the contractor, or terminate the contractor’s right to proceed for default.
Uncovering completed work may trigger adjustments
If the Government decides to examine completed work by removing or tearing it out before final acceptance, the contractor must provide the needed support. If the work is defective due to the contractor or subcontractors, the contractor pays the examination and reconstruction costs; if the work is compliant, the contractor is entitled to an equitable adjustment, including time extension if delayed.
Acceptance is final with limited exceptions
Unless the contract says otherwise, the Government must accept completed work, or separable portions of it, as promptly as practicable after completion and inspection. Acceptance is final and conclusive except for latent defects, fraud, gross mistakes amounting to fraud, and rights under any warranty or guarantee.
Responsibilities
Contractor
Maintain an adequate inspection system; perform inspections to ensure compliance; keep complete inspection records; provide access to records; conduct work under the general direction of the contracting officer; furnish facilities, labor, and materials needed for inspections and tests; support special, full-size, and performance tests; correct or replace nonconforming work at no extra cost unless the Government accepts it with a price adjustment; promptly segregate and remove rejected material; pay for extra inspection costs caused by unready work or necessary reinspection/retest; and support uncovering or reconstruction when the Government examines completed work.
Contracting Officer
Direct contract administration; authorize any change to specifications or contract terms in writing; determine when inspections and tests are required; ensure inspections are performed without unnecessary delay; decide whether to accept nonconforming work in the public interest with an appropriate price adjustment; determine whether completed work or separable portions can be accepted; and issue equitable adjustments or time extensions when Government-directed examination shows the work was compliant.
Government Inspector
Inspect and test work before acceptance within the scope of the contract; observe compliance and report findings; not relieve the contractor of any contract requirement; not authorize changes to specifications or contract terms without written contracting officer authority; and conduct inspections in a manner that does not unnecessarily delay the work.
Government
Use inspection and testing rights for its own benefit; pay attention to acceptance rules and post-acceptance rights; charge the contractor for additional inspection costs when the clause allows; and preserve rights for latent defects, fraud, gross mistakes amounting to fraud, and warranty or guarantee claims after acceptance.
Subcontractors
Perform work that conforms to contract requirements because defects attributable to subcontractors are treated as contractor responsibility; support the contractor’s inspection and correction obligations through compliant workmanship and fabrication.
Practical Implications
Contractors need a real quality-control process, not just end-of-job inspection, because Government inspection does not shift responsibility away from the contractor.
Keep inspection records organized and current; if a dispute arises, those records can be critical to proving compliance or defending against rejection.
Do not rely on informal direction from a field inspector to change scope, materials, or specifications; only the contracting officer can authorize contract changes in writing.
Schedule work carefully so it is actually ready when you request inspection, because failed readiness can lead to reinspection charges and delay.
If the Government asks to uncover or tear out completed work, document the request, the condition of the work, and any resulting delay or extra cost so you can support an equitable adjustment if the work is compliant.
Rejected work should be segregated and removed quickly; leaving it in place can complicate site safety, progress, and the Government’s ability to verify correction.
Acceptance matters, but it is not the end of all Government rights: latent defects, fraud, gross mistakes amounting to fraud, and warranty claims can still arise after acceptance.
Official Regulatory Text
As prescribed in 46.312 , insert the following clause: Inspection of Construction (Aug 1996) (a) Definition. "Work" includes, but is not limited to, materials, workmanship, and manufacture and fabrication of components. (b) The Contractor shall maintain an adequate inspection system and perform such inspections as will ensure that the work performed under the contract conforms to contract requirements. The Contractor shall maintain complete inspection records and make them available to the Government. All work shall be conducted under the general direction of the Contracting Officer and is subject to Government inspection and test at all places and at all reasonable times before acceptance to ensure strict compliance with the terms of the contract. (c) Government inspections and tests are for the sole benefit of the Government and do not- (1) Relieve the Contractor of responsibility for providing adequate quality control measures; (2) Relieve the Contractor of responsibility for damage to or loss of the material before acceptance; (3) Constitute or imply acceptance; or (4) Affect the continuing rights of the Government after acceptance of the completed work under paragraph (i) of this- section. (d) The presence or absence of a Government inspector does not relieve the Contractor from any contract requirement, nor is the inspector authorized to change any term or condition of the specification without the Contracting Officer’s written authorization. (e) The Contractor shall promptly furnish, at no increase in contract price, all facilities, labor, and material reasonably needed for performing such safe and convenient inspections and tests as may be required by the Contracting Officer. The Government may charge to the Contractor any additional cost of inspection or test when work is not ready at the time specified by the Contractor for inspection or test, or when prior rejection makes reinspection or retest necessary. The Government shall perform all inspections and tests in a manner that will not unnecessarily delay the work. Special, full size, and performance tests shall be performed as described in the contract. (f) The Contractor shall, without charge, replace or correct work found by the Government not to conform to contract requirements, unless in the public interest the Government consents to accept the work with an appropriate adjustment in contract price. The Contractor shall promptly segregate and remove rejected material from the premises. (g) If the Contractor does not promptly replace or correct rejected work, the Government may- (1) By contract or otherwise, replace or correct the work and charge the cost to the Contractor; or (2) Terminate for default the Contractor’s right to proceed. (h) If, before acceptance of the entire work, the Government decides to examine already completed work by removing it or tearing it out, the Contractor, on request, shall promptly furnish all necessary facilities, labor, and material. If the work is found to be defective or nonconforming in any material respect due to the fault of the Contractor or its subcontractors, the Contractor shall defray the expenses of the examination and of satisfactory reconstruction. However, if the work is found to meet contract requirements, the Contracting Officer shall make an equitable adjustment for the additional services involved in the examination and reconstruction, including, if completion of the work was thereby delayed, an extension of time. (i) Unless otherwise specified in the contract, the Government shall accept, as promptly as practicable after completion and inspection, all work required by the contract or that portion of the work the Contracting Officer determines can be accepted separately. Acceptance shall be final and conclusive except for latent defects, fraud, gross mistakes amounting to fraud, or the Government’s rights under any warranty or guarantee. (End of clause)
