Deep, complicated, and detailed excavations in unstable, problematic ground conditions are our specialty. After decades in the water/wastewater industry, JKC practices solid, innovative solutions for almost every ground condition encountered. These skills provide the basis for knowledgeable and competitive earthwork estimates in and around the Chicagoland area.


Using GPS technology, JKC interfaces directly with your architect and engineer’s AutoCAD files, eliminating questions about grades and elevations. This technology allows JKC to self-perform layout and document existing conditions and to implement proposed design changes upon receipt. Our laser-controlled machine technology has allowed our firm to establish and obtain the most stringent tolerances associated with projects such as synthetic ball fields and ice rinks. Our Earthworks projects also include construction of berms, balancing of spoils on private/ industrial sites, landfill capping and environmental/remediation work.
