Terracon's Lenexa office opened its doors in the Kansas City area in 1978 as Soil Testing Services of Kansas. At the time, the Kansas City office was one of five offices located in Iowa and Kansas. In 1980, Soil Testing Services of Iowa and Soil Testing Services of Kansas united as Terracon Consultants, Inc. The Lenexa office grew and moved several times before its current location in 1999. While many of the services the office provides remain the same today as they were in 1978, engineering and testing has become faster and more sophisticated.
Terracon's Kansas City offices provide a full range of geotechnical, environmental, construction materials, and facilities engineering services. In 1999, the Lenexa office expanded to include a full services satellite location in Lee's Summit, Mo., to provide more responsive and convenient service to our Missouri clients. With more than 30 years of experience with offices in Kansas City, 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, AASHTO and USACE certified laboratory, supported by the largest field technician crew and equipment fleet in the metropolitan area.

kcICON is a $245-million "interstate connections" project upgrading I-29/35 to six lanes from just north of the Route 210 / Armour Road interchange to Independence Avenue. The project includes an additional southbound lane, numerous on-ramps and off-ramps reconstructed, and several interchanges reconfigured. An "iconic" cable-stayed bridge, expandable to eight lanes and capable of accommodating a future bicycle/pedestrian facility, is the key feature replacing the existing Paseo Bridge. As the geotechnical consultant for the kcICON project, Terracon drilled more than 200 borings along…
