ATL has provided Construction Materials Engineering and Testing (CMET) field and laboratory services for nearly a half-century, delivering professional and technical support on over 50,000 projects and counting.

ATL’s diverse client base has grown to include architectural, engineering, industrial, private commercial, non-profit, and governmental entities. Whether performing Quality Control or Quality Assurance, ATL’s wide range of in-house capabilities enhance our ability to provide efficient and flexible service throughout all phases of a project’s progression.

In providing CMET services, ATL meets the requirements of ASTM E 329, ASTM E 543, ASTM C 1077, ASTM C 1093, ASTM D 3666, and ASTM D 3740. ATL has AASHTO accredited, CCRL evaluated, and U.S. Army Corps of Engineers validated laboratories located throughout New York State and we participate in national proficiency sampling programs and conduct internal round-robin testing.

ATL is also an active member of the American Council of Independent Laboratories (ACIL) and recipient of ACIL’s “Seal of Excellence”. We work hard through this association to make a difference in improving quality of services within the CMET sector.


Mobile Laboratory

Our mobile laboratory system offers an innovative approach to providing on-site testing and inspection services, allowing for uninterrupted service and maximum laboratory access throughout a project's duration. Our mobile laboratory units are pre-configured and outfitted with calibrated testing equipment to meet the unique demands of each project. Mobile units can be made available for both short- and long-term assignments and have proven effective in a variety of applications (i.e., landfill construction, large commercial buildings, remote wind farm locations, etc.). If you would like to learn more about the benefits of our mobile laboratory program, please do not hesitate to contact us.
