Structural Steel and Bolting Special Inspector S1 Special inspectors working under S1 certification spend their days verifying bolt tension with calibrated wrenches, documenting weld quality on high-rise frames, and signing off on connection work that holds buildings together. Your role bridges the construction site and the engineer’s office, catching installation gaps before they become structural liabilities. The exam drills you on AISC standards, torque specifications, and the inspection protocols that contractors depend on to pass final approval.
