9.2. Other General Information

9.2.1. When multiple inspection agencies are involved on the same project, how is their work coordinated?

When shop work is subjected to inspection by two or more inspectors or inspection agencies, interpretations and evaluations often conflict because acceptance criteria vary dramatically from inspector to inspector. Therefore, work performed by two or more inspectors or inspection agencies should be coordinated and standardized. 

The contract documents must include all requirements, in detail or by reference, to appropriate standards and codes that are applicable to the satisfactory end use of the structure. Additional requirements cannot be imposed on the work by inspection personnel under the generic heading of workmanship. When subsequent requirements to those specified in the contract documents are deemed appropriate for end use of the structure, they should be appended to the contract documents through contract changes. 

All involved parties should cooperate with the fabricator's inspection department and agree on interpretations of acceptance criteria before work is completed and shipped. Rejection of members subjected to re-inspection activities should be limited to structurally significant conditions. Minor conditions that do not affect the serviceability of the structure should not be cause for rejection. A pre-fabrication conference can facilitate production in a timely and economic manner. Timeliness of inspection is important to the efficiency of fabrication and inspection and the avoidance of rework and delays.

9.2.2. What quality assurance procedures must fabricators follow?

The fabrication shop should maintain a quality control program to assure that all work is performed in accordance with the codes and specifications applicable to the contract. AISC recommends that owners use the AISC Certification Program to evaluate the quality program of fabricators for specific structures. The AISC Quality Certification Program assures that fabricators have the expertise, equipment, procedures, and ability to produce steel structure consistent with their level of certification. If the owner requires a more extensive quality program or independent inspection, this should be clearly stated in the contract documents, including the definition of the scope of such inspection.
