IAS AC 291 Accredited Fireproofing Special Inspection Agencies

Fireproofing Special Inspection is a critical process where building code officials, known as the Authority Having Jurisdiction (AHJ), delegate the inspection of fireproofing disciplines to independent, third-party entities in various global jurisdictions.

The IBC, specifically Chapter 17, requires that Special Inspection Agencies—whether structured as C-Corporations, LLCs, S-Corporations, LLPs, or similar entities—demonstrate technical expertise, possess specialized equipment, and employ competent inspectors to verify that fireproofing materials, such as Sprayed Fire-Resistive Materials (SFRM) and Intumescent Fire-Resistive Materials (IFRM), are installed in compliance with approved designs, listings, and standards like those from UL or ASTM. These requirements ensure that fireproofing systems maintain structural integrity and fire-resistance ratings under fire conditions, protecting lives and property.

The International Accreditation Service (IAS) Accreditation Criteria (AC) 291 program provides a rigorous, quantifiable framework to validate a Fireproofing Inspection Agency’s capabilities, assessing their management systems, inspector qualifications (including certifications and field experience), and operational processes to ensure consistent, high-quality inspections. For a Special Inspection Agency, achieving IAS AC291 accreditation is essential as it not only proves compliance with IBC mandates but also builds trust with AHJs, enhances credibility, and ensures adherence to building codes, contributing to safer built environments by confirming the agency’s ability to deliver expert fireproofing inspections that uphold safety and regulatory standards.
