NIGP 94159 Inspection/Examination Services, Non-Destructive (Ultrasonic Testing, Dye Penetrant Testing, Radiography, Etc.), Item tier, encompasses turnkey non-destructive testing and inspection work that state and local governments are now procuring across electrical systems, water infrastructure, building safety systems, and structural integrity applications. Recent solicitations show cities and utilities buying Certified Welding Inspector oversight for ASME boiler code compliance, annual thermography surveys of electrical distribution systems, cathodic protection assessments for water mains, in-building radio frequency coverage testing to NFPA 1225 standards, and underground electrical equipment inspections under Florida Public Service Commission rules. The issuing bodies include city procurement offices (Phoenix, Austin, Dallas, Milpitas, Fort Myers, Bradenton), utility cooperatives (Florida Keys Electric), and state environmental departments (Washington Department of Ecology).
