THE DIRTBID REGIONAL MODEL · KANSAS
Sitework in Kansas on the same Richmond Metro = 1.00 scale as the rest of DirtBid: 8 cost regions and 105 counties, each with a soil-risk rating from USDA and USGS data. Kansas City Metro (Kansas side) runs highest at 0.89×; Joplin Metro (Kansas side) lowest at 0.80×.
Kansas 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
From USDA soil survey data, the most common across the state: shrink-swell clay (31 of 105 counties rate high), water table (13 of 105 counties rate high), dewatering (13 of 105 counties rate high). A parcel can differ from its county, so read the survey for your exact site.
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 Kansas, so use them for planning, not a final bid.
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.
