NYC Special Inspections
DOB-required special inspection and progress inspection services ensuring construction compliance with NYC Building Code Chapter 17, IBC Section 1704, approved drawings, and manufacturer specifications. Licensed PE with 28+ years of experience serving all five boroughs.
What Are Special Inspections in NYC?
Special inspections are mandatory, third-party construction oversight services required by Chapter 17 of the NYC Building Code (paralleling IBC Section 1704). The NYC Department of Buildings requires these inspections for critical structural components — including structural steel, concrete, masonry, post-installed anchors, spray-applied fireproofing, and smoke control systems — to ensure work is performed in strict accordance with approved construction documents and applicable code provisions.
Special inspections have been mandatory for all NYC construction jobs whose applications were submitted on or after July 1, 2008. They include inspections of selected materials, equipment, installation, fabrication, erection, and placement of components and connections. These inspections confirm compliance with approved construction documents and referenced standards required by NYC Building Code Chapter 17.
As an IAS-accredited Registered Special Inspection Agency with over 28 years of NYC experience, we are authorized to perform all categories of special inspections and progress inspections under NYC Building Code Chapter 17. We provide comprehensive quality oversight — from initial TR1 designation and scope coordination through daily field inspections, deficiency resolution, and final signoff documentation.
Our accreditation under NYC Building Code Section (c)(3) of 1 RCNY 101-06 and compliance with ISO/IEC 17020 and ASTM E329 standards means your project has the highest level of independently verified inspection quality under NYC DOB rules.
Why Special Inspections Matter
Special inspections provide an independent layer of quality assurance beyond the contractor's own oversight. Deficiencies in structural components — a missed weld, improperly consolidated concrete, or an incorrectly installed anchor — can compromise building safety for decades. Third-party verification ensures these critical elements are built right the first time.
IAS Accreditation & Standards
NYC DOB Rules 1RCNY 101-06 and 101-07 require IAS accreditation or equivalent for all Class 1 projects. Our agency maintains full compliance with all applicable accreditation requirements.
Licensed Professional Engineer
Every inspection is backed by a Licensed Professional Engineer in the State of New York with direct knowledge of NYC DOB procedures, code requirements, and construction practices across all five boroughs.
