Which documentation is typically required to demonstrate quality control on a structural steel project?

• A. Project budgets and cost reports
• B. WPS/PQR records, weld maps, NDT reports, material test reports (MTRs), inspection logs, and non-conformance reports
• C. Employee training records only
• D. Photos of the site only

Answer: (B)

Quality control on a structural steel project hinges on a complete, traceable set of documentation that proves welding and materials meet the required standards. Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR) show that the welding methods are defined and have been tested for reliability, so every weld can be reproduced to the same quality. Weld maps identify where each weld is located, its size, type, and inspection status, tying fabrication back to the design. Non-destructive testing (NDT) reports provide objective evidence of weld integrity without damaging the work. Material Test Reports (MTRs) certify the steel’s chemical makeup and mechanical properties meet the project specs. Inspection logs capture ongoing verification during fabrication and erection, while non-conformance reports document any deviations and the corrective actions taken. Collectively, these records establish a thorough quality-control trail.

Financials, training records, or photos alone don’t provide the complete, test-backed, traceable evidence required to prove quality in every weld and material, so they don’t fulfill the same purpose.
