SPECIAL INSPECTIONS

The purpose of Special Inspections is to enhance the safety of construction projects by improving the integrity of inspections and preventing unqualified technicians from evaluating material installations. 

 
Quadrant Engineering Safety Above All
 

Special Inspections have been part of the New York City Building Code since 2008, superseding what used to be called “Controlled Inspections.” Performed at critical points during most repair and upgrade projects, Special Inspections verify that construction work critical to safety and property protection has been conducted according to the project’s approved construction documents, as well as to New York City Building Code standards.

Quadrant Engineering is a certified Class 2 Special Inspection Agency with the New York City Department of Buildings.
