Most Wasatch Front communities are Seismic Design Category D (SDC D) per ASCE 7-22. IBC Chapter 17 requires a Special Inspection Program (SIP) for certain structural elements in SDC C+ buildings: concrete work (slump, air content, cylinder samples per ACI 318), masonry (mortar mix, grout lift height, rebar placement), structural steel welding (per AWS D1.1), high-strength bolting (installation torque verification), and anchor installation. For residential wood-frame construction, the standard building department framing inspection covers shear wall nailing, hold-down hardware, and anchor bolt placement, but the engineer of record may require structural observation visits at critical stages. RainFire Builders coordinates special inspection requirements with the structural engineer and ensures all required special inspections are scheduled, performed, and documented before those elements are concealed.
