STRUCTURES INSPECTION
At GRIT FORCE, we deliver highly specialized structural and nondestructive testing (NDT) inspection services across California’s most complex infrastructure projects. Our certified professionals support both public and private sector clients by ensuring that bridges, highways, pipelines, and facilities meet the highest standards of safety, performance, and compliance.
From fabrication plants to active job sites, our team uses welding inspection, NDT techniques, and destructive testing to generate accurate, actionable insights. Whether performing source inspection, quality validation, or materials engineering analysis, Grit Force inspectors are trained to deliver dependable results in highly regulated and time-sensitive environments.
What sets us apart is our role in statewide Caltrans projects, including ongoing QA/IQA services. Our inspectors are actively supporting design-build and CMGC mega-projects like US-101 HOV expansions in Santa Barbara, the I-405 Improvement Program, and multimodal enhancements along US-50. These assignments demand rigorous inspection, clear communication, and collaboration with Resident Engineers, Structure Representatives, and regional labs.
