Fabrication Shop Audits and Inspections

Dunlop NDT Fabrication Shop Services Fabrication shop audits and inspections are a common requirement to remain in compliance with many commercial, renovation, and rehabilitation project requirements. In addition to standard ‘spot check’ style audits, many projects require part-time and full-time inspections and monitoring throughout the fabrication process to verify fabrication is in accordance with approved shop drawings, specifications and codes.

Inspections are performed by certified inspectors using standard NDT methods including Visual Testing (VT), Penetrant Testing (PT), Magnetic-Particle Testing (MT) and Ultrasonic Testing (UT).

Certifications required to perform fabrication shop inspections include Certified Weld Inspector (CWI), ICC (S1 & S2) and SNT-TC-1A Compliant NDT Level II and Level III certifications.
