Geotechnical Engineering & Materials Testing

Engineering & Testing Consultants, Inc. (ETC) was founded in Prescott in 1981.  We provide geotechnical consulting services to a full range of projects, from residential to commercial development, and public facilities and infrastructure improvements.

ETC maintains a local nationally accredited materials laboratory, and performs most field explorations with our truck-mounted drill rig.  With more than 3 decades of experience in the area, we have an extensive knowledge of the unique soil conditions within the tri-city area, and other northern Arizona communities.  Our experience and technical resources combine to produce cost-effective geotechnical engineering recommendations that take into account unique site-specific soil conditions and design requirements.

Our highly experienced staff of ATTI and ACI accredited field and laboratory soils technicians provide materials testing and special inspection services during the construction process to ensure the project is completed in accordance with the design and project documents.
