Code Compliance, Referenced Standards, and Inspector Responsibilities
Domain 7 tests the code framework and the inspector's professional duties: what must be inspected, when, and how nonconformance is reported.
Code framework
- IBC Chapter 17 establishes special inspection and structural observation requirements; the prestressed concrete special inspector works under it.
- ACI 318 governs design and construction requirements, including steel, concrete, and prestressing provisions.
- ACI 301 gives construction and inspection requirements.
- ASTM standards define products and test methods: A416, A421, A722, and A886 for steel; C31, C39, C143, and C172 for concrete.
- PTI documents cover post-tensioning systems, grouting, and installation practice.
Inspector responsibilities
Verify approved plans and submittals before work; perform inspections at the required frequency; hold work at defined hold points; document observations, measurements, and test results; report nonconformance to the contractor, the design professional, and the AHJ; maintain records. The inspector observes and reports - the inspector does not direct the contractor or approve design changes.
Worked example
Strand arrives without a mill certificate, and the contractor asks to place it while the paperwork is located. The inspector documents the lot, holds placement, and notifies the design professional. Placement without traceable certification would violate the submittal and acceptance requirements.
Traps
- Accepting a verbal field change without written approval.
- Approving a substitution of anchorage components.
- Failing to report a known nonconformance because it was "fixed later."
- Performing inspections outside your certification scope.
- Relying on shop drawings that have not been approved by the design professional.
