Looking for Reliable Special Inspection Services?

FAQ - Special Inspection Services

Special inspection is a code-mandated verification process required under IBC Chapter 17 or other state and local codes, to confirm that critical construction activities are performed in accordance with approved construction documents. These inspections focus on structural and life-safety elements to ensure materials, workmanship, and installation methods meet design intent and applicable building codes.

A wide range of safety-critical building components typically require special inspections, including structural concrete, masonry, structural steel, welding, fireproofing, soils, deep foundations, cold-formed steel, wood framing, and proprietary anchors. Requirements vary by project type and jurisdiction, making early coordination with a qualified special inspection agency essential.

Special inspection services are performed by certified special inspectors employed by an independent specialized inspection agency.

At SOCOTEC, inspections are conducted by qualified engineers, structural inspectors, and certified technicians who hold credentials from recognized organizations such as ICC, ACI, AWS, and NICET, ensuring regulatory acceptance and technical accuracy.

Using an independent third-party inspection company ensures unbiased verification of construction activities, improves regulatory acceptance, and reduces risk for owners and developers. Third-party inspections also provide objective documentation that supports quality control, protects design intent, and helps resolve compliance issues efficiently throughout construction.

Yes. SOCOTEC is a Class 1 Special Inspection Agency certified by the New York City Department of Buildings (NYCDOB). Our special inspectors are authorized to perform all required NYC DOB special inspections and progress inspections, including those documented on TR1 and TR8 forms, in accordance with the NYC Building Code.

Absolutely. SOCOTEC integrates special inspection services with construction materials testing and nondestructive testing to deliver a comprehensive, coordinated approach to quality assurance. This integration streamlines communication, reduces coordination gaps, and provides consistent, reliable data that supports compliance, performance, and informed decision-making throughout the project lifecycle.
