Testing Engineers
Acquired Subsidiary
Testing Engineers provides construction materials testing, special inspection, NDT, and consulting in Northern California.
Core offerings are construction materials laboratory testing, code-required field special inspection, non-destructive testing, and materials consulting and forensics. Laboratory work spans tensile and hardness testing, Charpy impact, high-strength bolt testing, metallography, soils and aggregate analysis, asphalt testing, polymers, coatings, and failure analysis for construction and manufacturing clients.
Field inspection covers welding, bolting, reinforcing steel, concrete, masonry, fireproofing, soils placement, and asphalt construction under professional engineer oversight. NDT and consulting add dye-penetrant, magnetic particle, ultrasonic methods, concrete scanning, water intrusion investigation, and load testing for owners and structural engineers.
Testing Engineers differentiates with an IAS and ISO 17025 accredited materials laboratory focused on metallurgy, structural steel, high-strength bolts, and fasteners that few regional competitors match at the same depth. Combined field special inspection, soils and asphalt testing, NDT, and forensic consulting under one Bay Area operator reduces multi-vendor coordination for infrastructure and commercial projects.
Accreditations spanning AASHTO AAP, AWS, ICC, and DSA plus multi-lab capacity in San Leandro, San Jose, and Diablo Valley support code-submittal work and rapid local turnaround for Northern California clients.
The firm is regionally concentrated in the San Francisco Bay Area and California, so customers with multi-state programs may need additional laboratories outside its historic footprint until Certerra network integration is complete. Public materials emphasize laboratory and field capabilities rather than software-led digital delivery platforms that some national TIC competitors market as differentiators.
Pending integration into Certerra California operations creates transitional brand and operational uncertainty for clients who historically contracted with Testing Engineers as a standalone employee-owned laboratory.
