Cement and Concrete Reference Laboratory

Ninyo & Moore's testing equipment is calibrated annually by representatives utilizing equipment traceable to the National Institute of Standards and Technology, and is regularly inspected by the Cement and Concrete Reference Laboratory (CCRL). In addition to our many certifications, our laboratories participate in soil, asphalt, and concrete proficiency sampling programs, including those administered by the AASHTO Materials Reference Laboratory (AMRL), the Cement and Concrete Reference Laboratory (CCRL), and the Caltrans Reference Samples Program (RSP).

Mobile Laboratory

Ninyo & Moore has the resources to establish an on-site mobile laboratory as may be required by the project specifications and/or in order to reduce sample transportation time. We have utilized our mobile laboratories on many projects to provide our clients with full-service construction materials testing services on site. When requested, our mobile laboratory will be transported to the site and, once established, our laboratory equipment will be re-calibrated and certified by the appropriate agencies before we commence with our laboratory testing. Results from our laboratory can be immediately delivered to our client without delay. We have found our on-site mobile laboratories to be very effective, especially for projects with multiple shifts and overnight work.

Materials Testing and Inspection QA/QC Program

Ninyo & Moore's Quality Assurance Program is designed to provide the documentation needed to establish confidence that the testing or inspection function is being performed adequately. The written documentation includes our Quality Systems Manual, internal and external audits of our program, and the results of our participation in semi-annual sample reference programs. This documentation is available to our clients for review. Ninyo & Moore also provides its clients with the "standard of care" necessary to do business in today's litigious society. Our materials reports and as-graded reports are signed by a registered professional engineer after undergoing a strict peer review process.
