AB 509 Wisconsin Assembly · 2025-2026 Regular Session

Relating to: alternative delivery of projects contracted by the Department of Transportation. (FE)

AB 509 updates Wisconsin's rules for highway project delivery by creating new definitions for alternative methods like "design-build" and excluding others. It establishes a $300 million annual funding limit for alternative delivery projects (adjusted yearly using the DOT's construction cost index), with a cap of six contracts per year. The bill specifically prohibits using "construction manager-general contractor" or "progressive design-build" methods in the pilot program. This directly affects the Wisconsin Department of Transportation, contractors bidding on highway projects, and state transportation budget allocations.
