Know what's in the dirt
before you sign the deal.
Sitework is the most dangerous line in your pro forma. DirtBid AI screens the parcel with official USDA soil data and prices the risk — so soil surprises become negotiating points instead of six-figure change orders.
At a glance
A $350 answer before you buy land
One Soil Report reads official USDA data for the parcel and flags marine clay, muck, karst, shallow rock, and water-table risk — before your money is committed.
Feasibility numbers in minutes
A Feasibility sitework number for your pro forma — regionally priced across 29 regions and 3,000+ counties across the US.
The $250,000 lesson, avoided
A real Virginia development recently ate a $250K unforeseen-soils change order that public soil data predicted. That gap between free data and signed contracts is exactly what DirtBid AI closes.
Contract-ready awareness
Sitework contracts exclude "unsuitable soils" — leaving the risk on you. DirtBid AI tells you what that exclusion is likely to cost before you negotiate it.
Every deal, every county
From Northern Virginia marine clay to Carolina Piedmont saprolite and Texas Blackland clay: county-by-county risk profiles with local cost multipliers, maintained in one place.
Reports your lender understands
A one-page branded Soil Risk Summary and a clean Feasibility PDF — built for investment committees, not just engineers.
In practice
Where sitework kills deals — and how developers get ahead of it
Land price is visible. Vertical construction is quotable. Sitework is the line item that moves — because it depends on what's underground. Marine clay that needs undercutting, a water table two feet down, karst that swallows a stormwater design, rock where the grading plan wanted dirt: each one can move a budget six figures after commitments are made. Standard contracts make it your problem, not the contractor's — "unsuitable soils excluded" is boilerplate for a reason.
DirtBid AI moves that discovery to the beginning: a $350 Soil Report on the parcel while it's still under study, then a Feasibility number with the region's real multiplier for the pro forma, then — when you're ready to negotiate — line-item awareness of what the soil exclusions in your contract are actually likely to cost.
