American Engineering Testing Revenue and Competitors

American Engineering Testing Inc. (AET) is an employee-owned, Minnesota corporation. We provide geotechnical, environmental, materials and forensics consulting and testing services to public and private sector clients. The firm was founded in 1971 and originally known as Geotechnical Engineering Corporation with offices in Roseville, Minnesota. In 1989, the 22-person firm was purchased by the current principals. In early 1990, the business was renamed American Engineering Testing, Inc. and moved to its current facility in the Midway area. The move to a larger and more centrally located, five acre site in the Twin Cities has facilitated planned growth in staff and service. In 1991 and 1992, AET added the first regional offices in Duluth and Mankato. Three years later, facilities in Rochester, Minnesota, and Wausau, Wisconsin, were opened, followed by new regional office/labs in Marshall, Minnesota, and Pierre, Sioux Falls, and Rapid City, South Dakota. In nine locations, the firm currently has a total staff of 196 full-time employees, increasing to approximately 230 with the addition of seasonal employees during construction season.
