Terracon was selected to provide geotechnical and testing services for the construction of the Karnes County Civil Detention Center, which is located on FM 1144, just outside of Karnes City. This project sits on 29 acres of land and consists of a single-story detention center, three two-story housing units (which holds 608 beds, but capable of expanding to 1,200), and associated parking and drive lanes. The scope of services we provided consisted of geotechnical analysis and design recommendations related to the preparation of the building pads, floor slabs, and the drilled pier foundations. The construction services included earthwork for 167,000 cubic yards of soil, 6,950 total yards of concrete for grade beams, foundation slabs, tilt walls, and concrete paving, 57 reinforced steel observations, and five structural steel observations. The Karnes County Civil Detention Center is the first-of-its-kind in the U.S., built from the ground up, and designed to make the immigration detention system less penal and more humane. To do this, the U.S. Immigration and Customs Enforcement (ICE) agency consolidates detainees into fewer facilities and provide access to more services, more recreation, and more natural light within the facilities.
