A Special Inspection Program (SIP) is a project-specific plan for the IBC Chapter 17 special inspections that verify critical structural elements are constructed to engineered specifications — by qualified third-party inspectors, not just the building department. For SDC D projects, the SIP typically covers: concrete (ACI 318 — slump, air content, cylinder samples); structural steel welding (AWS D1.1 — welder qualifications, weld quality); high-strength bolting (installation torque verification); and anchor installation (type, embedment, torque per manufacturer). The SIP is prepared before construction begins, identifies required qualifications for each special inspector, and establishes inspection frequency. RainFire Builders prepares, coordinates, and manages the SIP on every project requiring one, and delivers all special inspection reports in the project closeout package.
