FAR 52.246-21 Warranty of Construction: Federal Bidding Comparison Guide
On federal fixed-price construction projects, solicitations often include 52.246-21 Warranty of Construction. Prescribed under FAR 46.710(e)(1) when approved under agency procedures, this clause binds the prime contractor and flows direct operational obligations down through every subcontractor and supplier tier. For interior framing, drywall, and ceiling estimators, understanding where liability starts, where it resets, and how government-furnished items change the equation is vital before finalizing figures on bid day.
Base 1-Year Warranty vs. The 1-Year Repair Reset
Under paragraph (b) of the clause, the baseline warranty continues for a period of 1 year from the date of final acceptance of the work. If the government takes possession of any portion of the facility prior to final acceptance, the 1-year clock for that specific portion begins on the date possession is taken. Estimators building their general conditions estimates must identify whether phased occupancy is planned, because phased handovers trigger split warranty expiration dates across separate project areas.
This baseline stands in sharp contrast to the rules for corrective work under paragraph (d). When a defect or nonconformance requires remediation, the contractor must restore any work damaged during the fix. Crucially, the warranty for repaired or replaced work runs for an entirely new period of 1 year starting from the exact date of the repair or replacement. A single late callback near the end of the original 1-year timeline can extend warranty liability on that specific component for an additional 1 year, making installation quality critical on the initial build.
Contractor-Furnished Work vs. Government-Furnished Material and Design
Under paragraph (a), the contractor warrants that all contract work conforms to requirements and remains free of any defect in equipment, material, design furnished, or workmanship performed by the contractor or any subcontractor or supplier at any tier. This creates a broad, collective chain of responsibility across all trade tiers.
However, paragraph (i) introduces a major boundary by comparing contractor-provided scope with government-supplied inputs. The contractor is not held liable for repairing defects in material or design furnished by the government, nor for repairing damage resulting from defective government-furnished material or design. The single exception stated in the clause is negligence: if the defect or subsequent damage stems from the negligence of the contractor, subcontractor, or supplier at any tier, liability returns to the contractor. Subcontractors preparing their scope reviews can evaluate these protections alongside their standard bid exclusions and clarifications.
Standard Commercial Warranties vs. Direct Government Enforcement
Paragraph (g) dictates how trade and product warranties interact with federal contracting officers. For all express or implied warranties from manufacturers, suppliers, and subcontractors, the contractor must:
- Obtain all warranties that are customarily offered in normal commercial practice.
- Require those warranties to be executed in writing for the benefit of the government if directed by the contracting officer.
- Enforce those commercial warranties for the benefit of the government when directed by the contracting officer.
A distinct mechanism appears under paragraph (h). Once the prime contractor's primary 1-year warranty under paragraph (b) expires, the government does not lose its remedy against long-term manufacturer guarantees. Instead, paragraph (h) authorizes the government to bring suit at its own expense to directly enforce any remaining subcontractor, manufacturer, or supplier warranty.
Standard Clause Terms vs. Alternate I Brand Name Specifications
The standard text of FAR 52.246-21 Warranty of Construction holds the contractor liable for defects in equipment and design furnished under the contract. However, when an agency specifies equipment on a "brand name and model" basis, the contracting officer may insert Alternate I (Apr 1984).
Under Alternate I, paragraph (k) alters the risk profile: defects in the design or manufacture of equipment specified by brand name and model are explicitly excluded from the contractor's warranty. In return, the contractor must require the affected manufacturers, suppliers, or subcontractors to execute their warranties in writing directly to the government. Bidders comparing solicitation packages should check whether Alternate I is active before factoring proprietary equipment failure risks into their estimates.
Consequential Property Damage and Notice Rules
Remedying an isolated defect is only part of the contractor's exposure. Paragraph (c) states that the contractor must remedy, at contractor expense, any damage to government-owned or controlled real or personal property caused by a failure to conform to requirements or caused by defective equipment, material, workmanship, or design. For ceiling and drywall trades, an unaddressed leak or structural defect overhead could cascade into damaged government personal property below, all compensable under this clause.
The government must provide notice in writing within a reasonable time following discovery. Under paragraph (f), if the contractor fails to remedy the defect, failure, or damage within a reasonable time after receiving written notice, the government retains the explicit right to repair, replace, or otherwise remedy the issue at the contractor's expense. Furthermore, paragraph (j) preserves all government rights regarding latent defects, gross mistakes, or fraud under the contract inspection and acceptance provisions.
