NYCDOB Class 1 special and progress inspections — structural observation, code-required verification, and the signed statements the department needs before it will sign off.
Special inspections are not a courtesy review. They are a code obligation with named inspectors, prescribed frequencies and statements of responsibility that follow the project from foundation to sign-off.
Universal has been certified by the New York City Department of Buildings since 1994 and is an IAS-accredited special inspection agency under the AC291, AC473 and AC478 programs. Our inspectors hold ICC, ACI, AWS and ASNT certifications in the categories they inspect.
