Roles & authorities
Special inspector
A special inspector performs the focused, often continuous inspection that certain work requires on top of the ordinary building department inspections. Structural steel welding and high-strength bolting, concrete placement and reinforcement, post-installed anchors and soils are typical scopes. The specific inspections required, and who is qualified to perform them, are set by the adopted code and the project's inspection program — usually spelled out on the drawings by the engineer of record and enforced by the AHJ.
How it shows up on site
Special inspection is scheduled around the work itself: an inspector present while welds are laid or while concrete is placed, not a walkthrough afterward. Continuous items mean the inspector has to be there for the operation; periodic items can be checked at intervals. Work that proceeds without required special inspection often has to be exposed or tested again to prove it.
What proves it
Signed daily special inspection reports, tied to the specific pours, welds or bolted connections they cover, are the record. Pairing each report with dated photos of the exact condition — a weld before it's coated, rebar and embeds before the pour — means the turnover package stands on its own instead of relying on the inspector's memory.
Common mistakes
Treating a passed building inspection as if it covered the special inspection scope, or closing in work before the required inspection is done and signed. Confirm the inspection program on the drawings and schedule the inspector to the operation, not to the calendar.
