CTE Cal, Inc. (CTE) has some of the most diverse material testing capabilities in the Western United States and can be contributed to three driving factors. First, our clients trust CTE laboratory staff to support their projects. Second, we are continually adding new capabilities to the list of services we offer. Third, CTE staff are bold in their desire to expand into areas other labs avoid. These three factors have afforded CTE to work on some of the most interesting projects in the State. CTE has the capabilities and certifications to perform tests other commercial labs are not approved to perform. Our laboratories are managed based on a corporate Quality Control Manual based on the requirements in AASHTO R18. Our laboratories hold accreditation through some of the most reputable accreditation agencies including:
American Association of State Highway and Transportation Officials (AASHTO) AAP Program (See scopes of accreditation here)
Cement and Concrete Reference Laboratory (CCRL) (See scopes of accreditation here)
Federal Highway Administration (FHWA)
US Army Corp of Engineers (USACE)
California Division of the State Architect (DSA)
