THE DIRTBID REGIONAL MODEL · SOUTH CAROLINA
South Carolina Sitework Costs, Region by Region
Sitework in South Carolina on the same Richmond Metro = 1.00 scale as the rest of DirtBid: 11 cost regions and 46 counties, each with a soil-risk rating from USDA and USGS data. Charleston Metro runs highest at 1.00×; Florence Metro lowest at 0.81×.
South Carolina multipliers and county ratings are planning-level: built from federal price and soil data, and not yet checked against local bids or a local estimator.

FAQ
South Carolina Cost Questions
Which soil problems drive sitework cost in South Carolina?
From USDA soil survey data, the most common across the state: water table (24 of 46 counties rate high), dewatering (21 of 46 counties rate high), undercut (15 of 46 counties rate high). A parcel can differ from its county, so read the survey for your exact site.
Where do the South Carolina multipliers come from?
From the Commerce Department's Regional Price Parities, on the same Richmond Metro = 1.00 scale as Virginia. Across 29 reviewed regions that method missed by about 0.03 on average. They have not been checked against executed bids in South Carolina, so use them for planning, not a final bid.
How reliable are the South Carolina county ratings?
They are screening ratings from federal soil and geology data, not a local estimator's review and not a geotechnical report. Tested against 511 reviewed counties, they land within one level most of the time, and exact matches are less common. Get borings before you price a real site.
