Special Inspections (IBC Chapter 17) 

Testing being performed on spray-applied fireproofing material

Chapter 17 of the International Building Code (IBC), published by the International Code Council (ICC), requires Special Inspections on many commercial construction projects. These inspections involve observing and testing designated materials and building components to document whether they are installed in accordance with the approved plans, specifications, and applicable building code requirements. 

What Special Inspectors Do 

Individuals who perform Special Inspections observe specific building or structural features to verify compliance with the plans and specifications approved by the building official. Among other duties, a special inspector is required to observe and inspect items specified by the design professional and report any nonconforming items to the contractor. 

Inspectors are approved by the building official and are typically engaged by the owner or design professional. 

Why Special Inspections Exist 

Following the collapse of a hotel’s walkway in Kansas City in 1981, the United States House of Representatives sought a way to ensure that all public facilities were constructed according to the design plans as well as local building codes. In 1988, the Building Officials and Code Administrators International (BOCA) introduced the first Special Inspection requirements.
