5.4 Non-Conforming Work: Rejection, Notice, Correction Period & Owner Acceptance
Key Takeaways
Under AIA Document A201-2017 Section 12.2.1, the contractor must promptly correct work rejected by the architect or failing to conform to the Contract Documents, whether discovered before or after Substantial Completion, at the contractor's sole expense including additional testing and architectural fees.
The One-Year Correction of Work Period under A201 Section 12.2.2 requires the contractor to correct non-conforming work upon written notice from the owner received within one year after Substantial Completion; this callback right is distinct from broader statutory warranties and statutes of limitations.
Under A201 Section 2.5, if the contractor fails within a 10-day period following written notice to commence and continue correction of defective work, the owner may perform self-help to correct the work and charge architect-approved reasonable costs through the § 2.5/§ 9.5.1 process.
Under AIA Document A201-2017 Section 12.3, only the Owner holds the contractual authority to accept non-conforming work instead of requiring its removal; the architect cannot accept non-conforming work on the owner's behalf.
Acceptance of non-conforming work under Section 12.3 mandates an equitable reduction in the Contract Sum documented via Change Order; the architect evaluates technical, life-safety, and financial ramifications and assists the owner in establishing the appropriate credit value.
5.4 Non-Conforming Work: Rejection, Notice, Correction Period & Owner Acceptance
Non-conforming work—construction that fails to satisfy the requirements of drawings, specifications, building codes, or referenced industry standards—is an unavoidable reality on complex construction projects. Managing defective work requires strict adherence to the enforcement mechanisms codified in AIA Document A201-2017.
The project architect must navigate four distinct legal and administrative remedies:
- Rejection of Work during active construction under A201 § 4.2.6 and B101 § 3.6.2.2.
- The One-Year Correction of Work Period following Substantial Completion under A201 § 12.2.2.
- The Owner's Right to Carry Out the Work (Self-Help) under A201 § 2.5.
- The Owner's Right to Accept Non-Conforming Work with an equitable financial credit under A201 § 12.3.
Rejection and Prompt Correction of Work: A201 § 12.2.1
Under AIA Document B101-2017 Section 3.6.2.2 and AIA Document A201-2017 Section 4.2.6, the architect has the unilateral contractual authority to reject Work that does not conform to the Contract Documents. Whenever the architect considers it necessary or advisable, the architect also has the authority to require special inspection or testing of the Work under Section 13.4, whether or not such Work is fabricated, installed, or completed.
Contractor's Obligation to Correct (§ 12.2.1)
Once work is rejected by the architect, the contractor must promptly correct it:
- The contractor must correct rejected work promptly, whether discovered before or after Substantial Completion, and whether or not fabricated, installed, or completed.
- The contractor bears 100% of the cost of correction, which legally includes:
- Direct labor, materials, equipment, and subcontractor costs.
- Costs of uncovering, dismantling, repairing, and replacing other work of the owner or separate contractors damaged or destroyed by the correction.
- Additional testing, inspections, and re-testing services.
- Compensation for the Architect's additional services and expenses made necessary by the non-conforming work. Under B101 § 4.2.2.4, reviewing repetitive submittals or conducting repeat site visits caused by contractor default constitutes an Additional Service; the owner compensates the architect and deducts that amount from the contractor via Change Order.
Important
The Stop Work Distinction: While the architect has unilateral authority to reject non-conforming work, the architect does NOT have contractual authority to stop the work (halt jobsite operations). Only the Owner has the legal authority to order the contractor to stop the work under A201 Section 2.4 if the contractor fails to correct defective work or repeatedly fails to carry out the work in accordance with the Contract Documents.
The One-Year Correction of Work Period: A201 § 12.2.2
One of the most frequently misunderstood clauses on the ARE is AIA Document A201 Section 12.2.2, commonly (and misleadingly) referred to in the field as the "one-year warranty." In contract law, this is technically termed the One-Year Correction of Work Period.
Operational Rules of the Correction Period (§ 12.2.2.1)
- Commencement: The one-year period commences on the Date of Substantial Completion of the Work (or designated portion thereof), or from dates established for specific equipment placed into beneficial service by the owner.
- Written Notice Requirement: If the owner discovers defective work during this one-year period, the Owner must give prompt written notice to the contractor.
- The Waiver Penalty: Under Section 12.2.2.1, if the owner fails to notify the contractor and give the contractor an opportunity to make the correction during the one-year period, the owner waives the right to require correction by the contractor AND waives the right to make a claim for breach of warranty against the contractor for that specific defect. The owner cannot bypass the original contractor to hire an expensive third-party contractor without giving the original contractor the opportunity to correct its own work.
- Work first performed versus corrective work (§§ 12.2.2.2–.3): Work first performed after Substantial Completion has its correction period extended by the interval from Substantial Completion to actual completion of that portion. Corrective work does not extend the one-year period under § 12.2.2.3. Do not restart the clock every time a repair is made; a special warranty can provide different obligations.
Correction Period vs. General Warranty (§ 3.5) vs. Statutes of Limitations
Candidates must master the legal distinctions among these three concepts:
- The Correction Period (§ 12.2.2): A specific administrative remedy requiring the contractor to physically return to the jobsite and repair defects at its own expense upon written notice.
- General Warranty (§ 3.5): Under Section 3.5, the contractor warrants to the owner and architect that materials and equipment will be of good quality and new, that the Work will be free from defects not inherent in the quality required, and that the Work will conform to the Contract Documents. This warranty is NOT limited to one year.
- Statutory Limits (§ 12.2.5): Section 12.2.5 explicitly confirms: "Nothing contained in this Section 12.2 shall be construed to establish a period of limitation with respect to other obligations the Contractor has under the Contract Documents." If a roof develops structural leaks three years after Substantial Completion due to improper fastening concealed beneath insulation, the owner can sue the contractor for breach of the Section 3.5 warranty up to the state's Statute of Limitations or Statute of Repose, even though the one-year callback period has expired.
Owner Self-Help Remedy: A201 Section 2.5
When a contractor refuses, neglects, or repeatedly fails to correct defective work or carry out the work in accordance with the Contract Documents, the owner is not helpless. AIA Document A201-2017 Section 2.5 (Owner's Right to Carry Out the Work) provides a powerful self-help mechanism.
The ten-day self-help procedure
If the contractor fails to commence and continue correction within ten days after the owner's notice, the owner may correct the default. Both the action and amounts charged require the architect's prior approval. Under the 2017 text of § 2.5, the architect may withhold or nullify certification under § 9.5.1 to reimburse reasonable correction expenses and necessary additional architectural services. The clause does not require a contractor-signed deductive change order as the prerequisite for this remedy. The contractor owes a shortfall if current and future payments are insufficient and may dispute the action or costs through Article 15.
Owner's Right to Accept Non-Conforming Work: A201 § 12.3
In certain circumstances, non-conforming construction does not compromise structural integrity or life safety, and the cost or disruption of tearing it out exceeds the value of correction. Under AIA Document A201 Section 12.3, the owner may choose to accept the work instead of requiring its removal and correction.
The Golden Rule: Only the Owner Can Accept Non-Conforming Work
- Exclusive Owner Prerogative: Under Section 12.3, the Owner—and ONLY the Owner—holds the contractual authority to accept non-conforming work.
- The Architect Cannot Accept: The architect has the contractual authority to reject work (§ 4.2.6), but the architect cannot accept non-conforming work on the owner's behalf. An architect who tells a contractor, "Don't worry about that wrong tile color, I'll accept it," commits professional negligence and exceeds their contractual agency.
The Architect's Critical Evaluative Role
Although the owner makes the business decision to accept non-conforming work, the architect plays an essential advisory and gatekeeping role:
- Code, Accessibility, and Life-Safety Verification: The architect must verify that the non-conforming condition does NOT violate building codes, fire ratings, structural design loads, or ADA accessibility standards. An owner cannot legally accept a life-safety violation or code breach; the architect must refuse to certify any agreement that condones an illegal or hazardous condition.
- Technical and Durability Assessment: The architect evaluates whether the non-conformance will accelerate wear, increase operating costs, void manufacturer warranties, or alter building aesthetics.
- Calculating the Equitable Price Reduction: The architect determines the fair financial credit due the owner.
Documenting Acceptance via Change Order
Acceptance of non-conforming work must never be informal or verbal. Per Section 12.3, acceptance requires that:
- The Contract Sum shall be reduced by an equitable amount.
- Such adjustment must be formalized through an AIA Document G701 Change Order signed by the owner, contractor, and architect.
- Determine an appropriate and equitable reduction under § 12.3 based on the actual condition and agreement. A201 supplies no mandatory higher-of-two-values formula.
- Section 12.3 explicitly clarifies that such adjustment shall be effected whether or not final payment has been made.
Comparative Matrix: Contractual Remedies for Defective Work
| Remedy Mechanism | AIA A201 Clause | Primary Decision Maker | Required Procedural Notice | Financial Impact on Contract Sum | Architect's Mandatory Role |
|---|---|---|---|---|---|
| Rejection of Work | § 4.2.6 & § 12.2.1 | Architect | Written Field Report / Rejection Notice | No change in Contract Sum; contractor absorbs all correction costs | Unilateral authority to reject; determines adequacy of corrective work. |
| One-Year Correction Period | § 12.2.2 | Owner | Prompt written notice within 1 year post-Substantial Completion | No change in Contract Sum; contractor corrects at own cost; corrective work does not reset the period | Provides the owner-requested first-year meeting without additional compensation under B101 § 3.6.6.5; separately scoped investigations may be supplemental. |
| Owner Self-Help (Carry Out Work) | § 2.5 | Owner | Formal 10-day written notice to commence & continue correction | Architect-approved charges recoverable through withholding/nullification under § 2.5 | Must approve both the owner's self-help action and the approved charges. |
| Acceptance of Non-Conforming Work | § 12.3 | Owner (Owner ONLY) | Formal written proposal and Change Order negotiation | Deductive Change Order for equitable credit (diminution of value or cost savings) | Verifies life safety and code compliance; calculates equitable credit value. |
| General Warranty Claim | § 3.5 & § 12.2.5 | Owner | Formal legal claim prior to statute of limitations / repose | Recovery of actual damages or cost to cure latent defects | Acts as Initial Decision Maker (IDM) if claim is filed during project administration. |
During the final punch list inspection of an elementary school gymnasium, the project architect observes that the general contractor installed non-impact-resistant lay-in acoustical ceiling tiles from an unapproved manufacturer rather than the impact-resistant ceiling system specified in Section 09 51 00. The installed tiles meet all fire ratings, seismic suspensions, and sound absorption metrics, but lack impact testing certifications. The contractor offers the school district a $14,000 credit to leave the ceiling in place. The school board decides to accept the credit, preferring the cash savings for educational technology. The architect strongly objects, asserting that balls kicked during gym classes will damage the uncertified tiles, and demands that the contractor remove the ceiling. Under AIA Document A201-2017 Section 12.3, how must this situation be resolved?
The owner has the exclusive contractual right to accept the non-conforming ceiling tiles under Section 12.3, and the architect must document the acceptance and equitable credit of $14,000 via a Change Order, provided the installation does not violate life-safety or building codes.
The architect possesses unilateral authority to reject non-conforming work under Section 4.2.6, which contractually overrides the owner's decision to accept the work.
The owner cannot accept non-conforming work unless the contractor agrees to extend the general correction period from one year to ten years.
The dispute must be submitted to the Initial Decision Maker for a binding ruling before any financial credit can be applied.
Six months after the Date of Substantial Completion of a four-story outpatient surgical center, severe water leaks appear beneath an exterior curtain wall expansion joint, damaging drywall and surgical equipment. The owner calls an independent waterproofing contractor for non-emergency work, who executes $38,000 in remedial caulking and flashing repairs over a holiday weekend without contacting the original general contractor. Two weeks later, the owner forwards the $38,000 invoice to the original general contractor, demanding full reimbursement under the One-Year Correction of Work Period (A201 § 12.2.2). The general contractor refuses to pay. How does AIA Document A201-2017 allocate legal liability in this scenario? Assume no emergency exception, prior acceptance, or different applicable notice rule applies.
The contractor must pay the $38,000 invoice because Section 12.2.2 holds the general contractor strictly liable for all water infiltration defects occurring within one year of Substantial Completion.
The owner must split the invoice with the architect because the architect failed to discover the flashing defect during construction site visits.
The owner waived its right to require correction by the contractor and waived its right to make a claim for breach of warranty under Section 12.2.2.1 by failing to give the contractor prompt written notice and an opportunity to correct the work.
The contractor's performance bond surety must pay the $38,000 invoice under the standard AIA A312 warranty bond provisions.
A general contractor constructing a community center repeatedly fails to correct improperly installed, leaking roof scuppers and downspouts despite three written rejection notices and punch list reminders issued by the architect over a four-week period. The owner wishes to hire a third-party roofing contractor to repair the drainage system and deduct the expense from the general contractor's remaining contract funds. According to AIA Document A201-2017 Section 2.5, what mandatory procedure must the owner and architect follow to legally carry out this self-help remedy?
The owner may immediately hire the third-party roofer and deduct the costs via an architect's administrative memorandum without notifying the general contractor.
The owner must give the ten-day notice to commence and continue correction; if the contractor fails to do so, the owner may correct the default with the architect’s prior approval of both action and reasonable charges, reimbursed through § 9.5.1 withholding or nullification.
The owner must file an emergency petition for temporary injunctive relief in state civil court and obtain a judicial order authorizing self-help.
The architect must terminate the general contractor's contract for cause under Section 14.2 before any third-party trade contractor can be retained.
