Bonds & Surety› Find Construction Work to Bid › Kansas
Public construction work in Kansas is posted in four places: KDOT (Kansas Department of Transportation) for highway and civil work, Kansas eSupplier (the state's vendor portal) for state agency projects, your local city, county, and school district bid boards, and SAM.gov for federal work. Most are free to search. To win the work you will usually need a bond - Kansas requires a 100% performance and payment bond on public works contracts over $100,000.
If you build in Kansas and want into public and commercial work, the jobs are not hidden - they are advertised in the open, and most of the sources are free. Here is where to look, who runs each one, and the bond you will need to actually win the work.

Every open federal construction contract is posted on SAM.gov, and it is free to search and register. You need an active registration and a Unique Entity ID before you can bid. Federal jobs over $150,000 require performance and payment bonds under the Miller Act - see our Miller Act guide.
Kansas requires a bond of not less than the full contract amount on public works contracts exceeding $100,000 (K.S.A. 60-1111), covering both performance and payment. KDOT also requires a 5% bid bond on every highway letting. (K.S.A. 60-1111.) Below those points many jobs still require a bid bond just to submit. The bottom line: if you want public work in Kansas, you have to be bondable.
That is where contractors lose jobs to competitors who are no better at the work - the other bidder could produce the bond and they could not. It is usually more reachable than contractors assume. If you are not sure where your bonding stands, start with what a surety bond is, see how contractors qualify, or read the full national guide on how to find construction work to bid on.
Kansas certifies firms for the federal DBE program through KDOT. Federal DBE rules changed in late 2025 - confirm current status and eligibility before relying on it.
