Construction Materials Inspection and Testing
As a site is developed, our personnel are available to provide a variety of testing and inspection services on soils and construction materials. Our role during project construction is to provide documentation to owners, architects/engineers and governing jurisdictions that projects are built in conformance with the approved plans and specifications.
Our testing and inspection personnel and/or laboratories are certified by:
- International Conference Code (ICC)
- National Institute for Certification in Engineering Technologies (NICET)
- American Concrete Institute (ACI)
- American Welding Society (AWS)
- American Society of Nondestructive Testing (ASNT)
- Division of the State Architect (DSA)
- California Department of Transportation (CalTrans)
- AASHTO Materials Reference Laboratory (AMRL)
- Cement and Concrete Reference Laboratory (CCRL)
Our engineering professionals and testing and inspection personnel maintain a thorough working knowledge of the full range of current Codes and Standards related to soils and construction materials.
