Our laboratories are managed under the direct supervision of a State of California Registered Civil Engineer. SALEM administers an internal Quality Assurance Program (QAP) which outlines the required Quality Control and Quality Assurance practices for our firm.
Our manual is regularly updated to ensure up-to-date compliance with national agencies in which we have membership. Sections of our QAP include organization, policies, equipment list, calibration procedures and dates, internal quality review, handling complaints and corrective action, and key staff resumes.

In addition, our Auburn laboratory is certified by the Washington Association of Building Officials (WABO).
