structural spray-applied fireproofing inspection
Whenever fireproofing is required on your industrial or commercial project, special inspection is mandatory — WH Engineering provides the ICC-certified inspection services you need.
why is it required?
Spray-applied fireproofing (SFRM) protects your structural steel's fire-resistance rating — but only if it's installed correctly. Per IBC Chapter 17, special inspection is mandatory whenever a fire-resistance rating depends on SFRM thickness, density, or adhesion. Once fireproofing is concealed behind ceilings, ductwork, or finishes, deficiencies become costly — or impossible — to correct. Independent verification protects your project, your building official approval, and your bottom line.
Inspection scope:
Sprayed Fire-Resistive Materials
Thin-Film Intumescent Fire-Resistive Materials
Substrate condition and surface preparation
Dry film thickness (DFT) verification
Density testing per ASTM E605
Bond and cohesive/adhesive strength per ASTM E736 / E760 / E761
Application uniformity and coverage
Code compliance documentation and reporting
