Where each walk sits in the schedule
- High-strength bolting special inspection checklisthigh-strength bolting
- At fastener delivery, before installation begins, and at each connection during and after tightening — before it is covered or coated. Run by: A third-party or owner's-rep special inspector for structural steel, alongside the erector's bolt-up crew.
- Structural welding special inspection checkliststructural welding
- Before welding starts (qualifications and fit-up), during welding for critical joints, and at completion before coatings or fireproofing. Run by: A third-party or owner's-rep welding inspector, coordinating with the fabricator or erector's welding crew.
- Cast-in-place concrete special inspection checklistcast-in-place concrete
- Before the pour (reinforcement and embeds), at delivery (mix verification and sampling), and during placement and curing. Run by: A third-party or owner's-rep special inspector for concrete, with the placing crew and the testing lab.
- Soils and foundations special inspection checklistsoils & foundations
- At subgrade and bearing exposure, during fill placement and compaction, and throughout pile or pier installation. Run by: A third-party or owner's-rep geotechnical/special inspector, with the earthwork or foundation crew and the testing lab.
- Structural masonry special inspection checkliststructural masonry
- At material delivery, during laying and reinforcement placement, and at each grout lift and sampling. Run by: A third-party or owner's-rep special inspector for masonry, with the mason and the testing lab.
- Sprayed fire-resistive materials (SFRM) special inspection checklistsprayed fireproofing
- After the structure is accepted and the substrate is ready, during application, and before the assembly is enclosed. Run by: A third-party or owner's-rep special inspector for fire-resistive materials, with the applicator.
What most often sends special work back
- Pretensioning claimed on a summary sheet with no photo of a marked or verified connection.
- Faying surfaces coated or contaminated on a slip-critical connection that called for a clean surface.
- Fastener assemblies mixed on site so the lot verified in pre-installation testing is not the one installed.
- Welder qualification expired or not current for the position and process actually used.
- Completed welds coated before the visual inspection and any required NDT were recorded.
- Fit-up gaps and pre-heat left unverified on joints that called for them.
- Reinforcement signed off after forms were closed, so cover and spacing could not be verified.
- Test specimens taken and cured without the inspector present to witness the sampling.
