About Us

American Engineering Testing (AET) is an employee-owned corporation providing geotechnical, environmental, materials and forensics consulting and laboratory services to public and private sector clients in a broad spectrum of industries.

We have built our reputation on experience, quality and by focusing on individual solutions for our clients. Our engineers and certified technicians, including principals who are actively involved in project management, have decades of practical experience in their areas of specialization. They also have access to an extraordinary accumulation of site data and construction history in the Upper Midwest, which proves useful and adds to cost and time efficiency on many projects.

As a consulting engineering company and independent laboratory, quality is the nature and purpose of AET’s services. We analyze, test, monitor and inspect in order to document, verify and improve the design and construction effort. To that end, we are accredited by the AASHTO Materials Reference laboratory (AMRL) to perform geotechnical and construction services in accordance with ASTM: E329. AET’s in-house quality assurance/quality control program was established in 1993 to systematically and rigorously audit departments and office/labs on test procedures, calibrations and test accuracies.

Firm History

AET was founded in 1971 in Roseville, Minnesota and was originally known as Geotechnical Engineering Corporation. In 1989, the 22-person firm was acquired by the current principals. In early 1990, the business was renamed American Engineering Testing, Inc. and moved to the current headquarters. The move to a larger and more centrally located, five-acre site has facilitated phased growth in staff and service.

In the early 1990s, AET opened the first offices in Duluth and Mankato. Three years later, facilities in Rochester, Minnesota and Wausau, Wisconsin, opened, followed by new office/labs in Marshall, Minnesota; Pierre, Sioux Falls and Rapid City, South Dakota.

In 2006, AET bought the major assets of another leading consulting engineering firm, GME Consultants, and grew by 65 staff members. At the same time, we gained new office locations in Crosby and International Falls, MN and Menomonie, WI. Our Albertville, MN office opened in 2007. Green Bay, WI and Post Falls, ID opened in 2010.

Effective August 2, 2010, American Engineering Testing (AET) took a strategic step in its plans to increase its capabilities to serve clients in Wisconsin and South Dakota by acquiring certain selected service lines from Tetra Tech, Inc. in Chippewa Falls, Wausau and Seymour, WI and Sioux Falls, SD. The service lines include construction materials engineering/testing (CME), drilling and chemistry services.

In 2011, AET opened offices in Dickinson and Williston, North Dakota.
