1.4 Discrepancy Notification & Non-Conformance Resolution

The Nature of Discrepancies in Construction

In the realm of structural steel and high-strength bolting, perfection is the goal, but discrepancies are a reality. A discrepancy, or non-conforming item, occurs anytime the executed work deviates from the approved construction documents, the project specifications, or the referenced building codes. As a special inspector, your primary objective is not merely to find faults, but to identify these deviations early, document them accurately, and ensure they are brought to the attention of the responsible parties for correction. The International Building Code (IBC) Section 1704 establishes a very specific, mandated protocol for how special inspectors must handle and escalate discrepancies. Adhering strictly to this protocol is not optional; it is a legal requirement of your certification and your duty to the building official and the owner.

Immediate Verbal Notification to the Contractor

The discrepancy resolution process begins the moment non-conforming work is identified. The very first step, mandated by the IBC, is to bring the discrepancy to the immediate attention of the contractor. IBC 1704.2.4 says discrepancies "shall be brought to the immediate attention of the contractor for correction." In practice that notice is usually given in person to the contractor's site superintendent, foreman, or designated quality control representative, and then recorded.

The goal of this immediate verbal notification is to provide the contractor with the opportunity to correct the issue while the work is still ongoing, before it becomes a massive, costly problem or gets concealed by subsequent construction phases. For example, if you observe an ironworker using the wrong grade of bolt in a slip-critical connection, immediately informing the foreman allows them to swap the bolts right then and there. When communicating verbally, maintain a professional, objective tone. State clearly what the approved plans require and what you have observed in the field. Avoid giving direct instructions on how to fix the problem, as that crosses the line into directing the means and methods of construction.

Written Discrepancy Logs and Notices

If the contractor corrects the discrepancy immediately following your verbal notification, you simply document the occurrence and the correction in your daily report. However, if the contractor is unable or unwilling to correct the issue immediately, you must formalize the notification. This is done through a written Discrepancy Notice (sometimes called a Non-Conformance Report or NCR) and by entering the item into the job-site discrepancy log.

A formal written discrepancy notice must be clear, concise, and entirely factual. It must include the date, the specific location of the non-conforming work (e.g., "Column line A-4, 3rd floor beam-to-column connection"), a detailed description of the deviation, and a direct reference to the specific detail in the approved construction documents or code section that is being violated. This written notice is provided to the contractor, and a copy must be maintained in the inspector's job-site records. The discrepancy log serves as a running tracker of all open issues, ensuring nothing falls through the cracks as the project progresses.

Timeframe for Contractor Correction

Once a written discrepancy notice is issued, the contractor is given a reasonable timeframe to correct the work. The definition of a "reasonable timeframe" depends entirely on the nature of the issue, the construction schedule, and the project specifications. Some minor issues, like replacing a missing washer, can be corrected within hours. More complex issues, such as a severely misaligned column or a rejected complete joint penetration (CJP) weld that requires gouging and re-welding, may take days or require a formal Request for Information (RFI) to the structural engineer for a specialized repair procedure.

During this timeframe, the special inspector tracks the item on the discrepancy log. It is critical that the non-conforming work is not concealed or permanently built upon until the correction has been completed and re-inspected. The special inspector must monitor the area to ensure subsequent trades do not cover the defect.

Escalation Protocol: RDPiRC and Building Official

The true test of a special inspector's authority comes into play when a contractor fails to correct a documented discrepancy. If the contractor refuses to fix the issue, or if they attempt to proceed with subsequent construction phases that would cover or finalize the non-conforming work, the inspector must escalate the issue immediately.

IBC 1704.2.4 states that if discrepancies are not corrected, they shall be brought to the attention of the building official and the Registered Design Professional in Responsible Charge (RDPiRC), typically the structural engineer of record, prior to the completion of that phase of the work. The timing matters: the notice must reach them while the work can still be evaluated or corrected, not after it is buried. Put the escalation in writing so it becomes part of the record. The RDPiRC needs this information because the uncorrected work may compromise the structural integrity of the building, and they may need to evaluate if the "as-built" condition is acceptable or if a redesign is required. The building official needs this information because they hold the ultimate authority to enforce the code and halt construction.

Stop-Work Authority vs. Duty to Notify

A common misconception among new inspectors and contractors alike is the extent of the special inspector's authority to stop work. It is crucial to understand this distinction: The special inspector does not have the legal authority to issue a stop-work order.

Only the building official (the AHJ) has the authority to halt construction; the IBC places stop work orders with the building official (Section 115). The special inspector's duty is strictly to observe, document, and report. If you observe work proceeding over an uncorrected discrepancy, your responsibility is to immediately notify the building official and the structural engineer. You tell the contractor that you are reporting the uncorrected status, but you cannot legally order the ironworkers to lay down their tools and leave the site. By promptly reporting the issue to the building official, you empower the AHJ to exercise their stop-work authority if they deem it necessary to protect public safety.

Documenting Corrective Actions and Re-inspection

When a contractor finally addresses a discrepancy, the special inspector's job is not finished until the correction is fully verified. The contractor must notify the special inspector when the repair or correction is complete. The inspector then performs a re-inspection of the affected area.

If the corrected work now meets the requirements of the approved construction documents, the inspector updates the discrepancy log, marking the item as "resolved" or "closed." The daily inspection report for that day must explicitly detail the re-inspection, referencing the original discrepancy notice number and confirming that the corrective action complies with the plans. This creates a closed-loop paper trail, proving to the building official at the end of the project that every identified problem was ultimately solved. If a repair procedure was engineered by the RDPiRC (e.g., a stamped sketch showing an alternate weld detail), the inspector must verify the work against that specific engineered repair document, not the original plans.
