We are diligent in training our personnel for our specialties: soil, aggregate, concrete, and asphalt testing and design. Only personnel certified in the respective field are sent to provide testing services. Although virtually all of our technicians are cross-trained, a soil technician must have WAQTC certification, a concrete technician must have ACI certification, and an asphalt technician must have the appropriate level of LabCAT certification. These certifications are required by the Colorado Department of Transportation, and we comply with their requirements whether or not we are working on a CDOT affiliated project.

WesTest also has ACI certified Concrete Transportation Construction Inspectors to monitor that proper placement and construction methods are used during construction
