To assure the highest levels of technical competency and professionalism, our laboratory is accredited by the American Association of State Highway and Transportation Officials AASHTO Accreditation Program and regularly audited and accredited by the New Mexico Department of Transportation (NMDOT). As a part of our Quality System, our laboratory participates in round robin proficiency testing with the NMSH&TD, the AASHTO Cement and Concrete Research
Laboratory (CCRL) and the AASHTO Materials Reference Laboratory (AMRL).

Pettigrew & Associates, P.A. has been providing professional engineering testing services for more than 40 years. Our experience includes:

  • Geotechnical evaluation of existing soil conditions for design of pavement sections, foundations and structures.
  • Consulting services for material pit sources.
  • Design and analysis of concrete and asphaltic mixtures.
  • Construction Materials Testing on soils, asphaltic mixtures, aggregates, and concrete.
  • Specialized design and analysis of flexible and rigid mixtures for DOE/WIPP projects as well as
    local clients.

As an independent materials laboratory, we can be a valuable partner in meeting your quality
control needs. Throughout the life of a project, constant attention to quality in partnership with
Pettigrew & Associates, P.A. can result in your projects’ success.
