The scope
What We Handle
Grading and excavation is the earthwork that gets a site build-ready, and we coordinate every piece of it to a written scope before anything moves.
Lot grading & leveling
Cutting and filling to the right slope for drainage and a stable, build-ready pad.
Excavation
Digging for foundations, footings, basements, drainage, and utilities.
Site shaping & access
Preparing a lot so the build, driveway, or outdoor project sits right.
Erosion & drainage grading
Moving water away from the house and the foundation, to a written plan.
Grading is usually one phase of a larger build. See the full site work and grading hub, or pair it with land clearing and drainage and erosion control.
Why Chonko
Why Coordinate Your Site Work With Chonko Construction
Earthwork is the part of a project you stop seeing once it's done, and the part that decides whether everything above it sits straight, drains, and lasts. Get it wrong and the cracks, settling, and standing water show up later, after the finishes are in.
As a licensed home builder, we coordinate the grading and excavation as one phase of the larger build, sequenced with the crews and permitting around it, so the site is right before the next trade shows up.
One coordinated scope
Earthwork sequenced with the build around it, not a disconnected dig-and-leave.
Permitting coordinated
Land-disturbance permits and stormwater compliance handled as part of the project.
In writing first
The scope, schedule, and price are set before equipment ever hits the site.
Cost drivers
What Drives the Price
Every lot is different, so we set the exact number in writing after we walk the site. A few things move it most:
Lot size & cut-and-fill volume
The more earth that has to move, the bigger the line.
Slope & soil
Steep grades and Midlands clay take more work to cut, fill, and compact.
Site access
Tight, wooded, or hard-to-reach lots slow the equipment and add time.
Haul-off
Trucking excess soil, rock, or debris off-site is its own line.
Drainage & erosion control
French drains, swales, and stormwater measures add scope.
Permitting
Land-disturbance permits and, on larger sites, a stormwater plan (SWPPP).
Columbia & the Midlands
Site Work in the Midlands
South Carolina's clay soil holds water and moves with the seasons, and our summer storms test every grade and drain on a property. Earthwork that ignores it is why so many lots end up with standing water, settling, and foundation trouble down the line.
We coordinate the grading and excavation for those conditions, cutting to proper depth, compacting a stable base, and shaping the lot so water runs away from the house instead of toward it. Done right at the start, the site stays put through Midlands clay, heat, and downpours.

Frequently Asked Questions
What is the difference between grading and excavation?add
Excavation is digging and moving earth (removing soil for a foundation, basement, or pool). Grading is shaping and leveling the ground to the right slope for drainage and construction. Most site projects need both; Chonko Construction handles them together under one contract.
How much does grading cost in Columbia, SC?add
Grading cost depends on lot size, slope, soil, and how much earth has to move. Every Chonko Construction project starts with a written scope, schedule, and price before work begins, so the number is clear up front. Typical Midlands ranges are published in our excavation cost guide.
Do I need a permit to grade my lot in Columbia, SC?add
Grading that disturbs soil usually requires a land-disturbance permit, and larger sites need a stormwater plan (SWPPP). Chonko Construction coordinates grading permits and compliance as part of the project.
