Our inspection and testing professionals are dedicated to making sure that the materials used on infrastructure projects stand up to rigorous safety and quality standards. We provide destructive and nondestructive testing for a wide range of materials and structures, offering our clients solid data and sound analysis that facilitate informed decisions. Our team is composed of nondestructive testing technicians certified in a variety of disciplines, welding inspectors, precast concrete inspectors, corrosion inspectors, and technicians certified in numerous California and AASHTO test methods.

Our inspectors and technicians differentiate themselves through their depth and breadth of experience—with most holding certifications across multiple disciplines, one Alta Vista technician has the training to perform the work of two or more inspectors. As an industry leader in fabrication inspection, we’re well prepared to take on our clients’ most difficult inspection needs.
