## Omitting an applicable item from the SSI is a common and consequential defect: a designer who lists concrete but omits post-installed anchors, high-strength bolting, or steel erection leaves those activities uninspected, and each is a separate required line item under IBC §1705. {note}
−## Where the Seismic Design Category is elevated mid-project -- by adoption of updated ground-motion data or a change in occupancy category -- the SSI shall be amended to add any masonry, steel, or other inspections newly triggered.

## The agency's laboratory performing concrete, soil, grout, and mortar testing shall be accredited for the test methods it performs.
−## Special inspection costs are owner-funded and are not included in the Contractor's base contract; the Owner shall retain and pay the agency directly. Identifying this responsibility in the Owner-Contractor Agreement early avoids a common budget dispute. {note}

## Retaining the agency too late is a recurring and expensive failure: if footing excavation, reinforcement placement, and the first concrete pours proceed before the agency mobilizes, that work is uninspected and may trigger non-conformance reports or removal. {note}

## Nondestructive testing personnel shall be qualified and certified per ANSI/ASNT CP-189 for each NDT method they perform.
−## ICC certification is granted by discipline -- Reinforced Concrete, Structural Masonry, Structural Steel and Bolting, Structural Welding, and Soils are separate credentials -- so a single inspector is rarely qualified across every discipline on the Project; the agency shall assign personnel accordingly. {note}

## For continuous inspection activities, the inspected operation shall not proceed when the special inspector is not present.
−## Ambiguous or missing continuous-versus-periodic designations are a frequent source of missed inspections: when arrival timing is uncoordinated, periodic inspections are skipped entirely. Every inspection item in the SSI shall carry an explicit designation. {note}
