Terracon assisted the City of Cherryvale prepare grant applications to conduct assessments in three target areas within Cherryvale.

In 1986, Terracon acquired Barnett, Stuart & Associates, Inc, a local consulting geologist firm which provided geotechnical and geological services across Kansas for more than 20 years. The office was immediately staffed and equipped to perform extended geotechnical engineering and construction materials engineering and testing services throughout Kansas. While many of the services, which the office provides, remain the same today as they were in 1965, engineering and testing has become faster and more sophisticated. The Topeka office provides a full range of geotechnical, environmental, and construction materials engineering services throughout Northeast and North Central Kansas. In 2007 the Topeka office expanded to include a construction services satellite location, including an AASHTO and USACE-certified laboratory, in Manhattan, Kan., to provide more responsive and convenient service to our clients. Our employees are extremely knowledgeable about local geologic conditions, construction materials procedures and codes, and environmental policies, regulations and concerns. We have a fully equipped, certified laboratory, supported by one of the largest field technician crew and equipment fleet in the region.
