Direct Answer
The Inspector of Record (IOR) is the licensed special inspector or inspection agency designated by the building official to perform required special inspections — including structural steel welding, bolting, and materials verification. The IOR has authority to observe work, document nonconformance, and direct work to stop if inspections reveal violations. Their acceptance is required for the building to receive a certificate of occupancy.
Full Explanation
IOR powers and responsibilities: (1) Observe all required special inspection activities — they have access to all work areas at all times. (2) Document nonconformances and issue written notices to the contractor. (3) Issue stop-work for conditions that pose immediate structural risk. (4) Submit periodic inspection reports to the building official. (5) Issue a final inspection report at project completion. The IOR is hired by and reports to the building owner — not the contractor. This independence is intentional: the IOR's obligation is to the code and the public, not to the contractor's schedule.
What This Means for Your Shop
The IOR is not your adversary — build a working relationship with them at project start. Brief them on your QC system, your WPS and welder qualifications, and your inspection hold-point schedule. An IOR who understands your process is more efficient to work with than one who's discovering your system on the fly.
Common Mistakes
Treating the IOR as an obstacle rather than a partner. Contractors who obstruct inspection access or argue with IOR findings create adversarial relationships that slow the project. Cooperate fully, provide documentation proactively, and address findings immediately.
Recommended Process
At project kickoff, request a pre-construction meeting with the IOR to review your QC plan, WPS, and welder qualifications. Provide copies of all relevant certifications. Establish a communication protocol for scheduling inspections at hold points.
