Site Work Contractor in Columbia, SC

Chonko Construction is a residential-scale site contractor. Our sweet spot is single lots and small-acreage sites, generally up to about four acres, where the ground needs to be made right for a home, an addition, or a full build. Typical equipment on our jobs is an excavator up to the 20-ton class and a skid steer, with loaders or a small dozer added for larger clearing and grading work. That range covers the earthwork on most Midlands residential lots.

When a job means moving serious weight and volume (heavy cut-and-fill, large-acreage clearing, deep excavation), we scope it as a custom build rather than force it into a fixed rate. That's not a safety line; it's about matching the right pricing to the real volume of work. If your lot is bigger or the earthwork is heavy, call us and we'll tell you straight whether it's our lane.

Site-work pricing is plan-dependent. At a minimum, the job has to clear county regulations, and depending on the lot, that can mean an engineered grading plan, a stormwater pollution prevention plan (SWPPP), or simply staying under the thresholds that trigger a land-disturbance permit. We've got all of it covered, but the level of plan and permitting a site needs is what moves the number.

• Basic scopes, fixed. Straightforward, well-defined work that stays under the permit thresholds (a day of grading, a standard driveway, a defined clearing area) is quoted at fixed-scope and day-rate pricing up front. These are our introductory site-work offers: you know the number before a machine rolls.
• Plan-driven scopes, custom package. When the lot needs engineered plans, permitting, and the heavier earthwork that comes with real weight and volume, we build it as a custom package: plans, permits, and the work scoped and priced together, in writing, before we start.

Site work bookends a build. It opens with site preparation in Columbia SC and closes with final grading and site restoration, the finish pass that resets topsoil, slope, and drainage once the heavy work is done. Pouring flatwork in between? See concrete driveways.
