Materials Testing & Special Inspection

Our Materials Testing and Special Inspection department is staffed by experienced inspectors and technicians who are certified through various state and national organizations, and who work under the direct supervision of registered professionals. Our staff is certified by the California Division of the State Architect, American Concrete Institute, International Code Council, American Welding Society, and other recognized agencies. All of our inspectors and technicians are cross-trained and certified in more than one area, thereby allowing each to perform multiple tasks on a project.
