Projects and Experience

Kolb is a trusted partner in the construction of site work, excavation, utility storm sewer installations, concrete swale, building pads, parking lot subgrade and access roads/entrances to construction sites.


Opening on October 6, 2015, the Mercy Virtual Care facility in Chesterfield, MO is the first of its kind in the United States, providing virtual medical services to rural hospitals, physicians and patients, as well as providing medical expertise and monitoring services to those who otherwise would be too far away to access specialists and other critical care personnel. Kolb was proud to be a part of the construction team bringing this innovative medical facility to fruition.

Paric Construction chose us to provide grading and foundation preparation for a private school in O’Fallon, MO. The Barat Academy school and stadium site required construction of a temporary construction entrance, clearing and grubbing over 15 acres, 230,800 cy of excavation and 55,000 cy of subgrade for the building pad. The parking lots required subgrade preparation, soil stabilization and lime slurry. A silt fence was installed, survey and layout was performed for a silt basin and screening was installed.

We were selected by Landesign, LLC to perform demolition and grading for the Pattonville High School Natatorium and Stadium in Maryland Heights, MO. This required 50,000 cy of excavation after building a temporary construction entrance. In addition to preparing the site for the athletic field and parking lots, we provided 84,300 cy of finish grade, survey and layout, soil stabilization and retaining wall over-excavation.
