MATERIALS TESTING AND SPECIAL INSPECTIONSampling and Testing Services Include:
Quality control and quality assurance in construction is a major concern to owners and project participants. Systematic verification and testing of construction materials is the best way that the architect and structural engineer can be assured that the materials and methods being used by the contractor are of the quality specified in the project documents and the applicable building codes.
Since 1978, Materials Testing, Inc. and its subsidiary KC Engineering Company’s full service laboratories have provided complete testing and inspection services, for all phases and materials used in the construction industry, for several thousand projects in the Northern California and Southern Oregon area. These services are conducted in the laboratory, in the fabricating plant, and/or at the construction site. On larger projects, we can even provide an on-site laboratory to minimize sample disturbance during transport and to expedite the required testing. Our experienced certified technicians address field-related issues by close coordination and communication with the project design team using common sense and practical approaches to develop timely, cost-effective solutions.
We maintain soils, concrete and aggregate testing equipment to service the testing needs required by the individual project specifications. Our equipment is calibrated and maintained by an independent agency. Our Redding laboratory has been accredited by the American Association of State Highway & Transportation Officials AASHTO) and conforms to the requirements set forth by ASTM E329. Further, our laboratory participates in the Cement and Concrete Reference Laboratory (CCRL) Proficiency Sample Program of the National Institute of Standards and Technology (NIST). We also currently participate in the Reference Sampling Program by the California Department of Transportation (Caltrans), AASHTO materials reference laboratory (AMRL) and the Asphalt Institute. We are licensed by the State of California, Department of Radiological Health to operate nuclear density and moisture testing devices and each of our technical staff is certified in their use. We employ a technical staff certified through state and national agencies such as the American Society for Testing and Materials (ASTM), International Code Council (ICC), Caltrans, National Institute for Certification in Engineering Technologies (NICET), the American Concrete Institute (ACI), and the American Welding Institute (AWS).
