Relating to the design-build method for certain government construction projects.

HB 5582 allows Texas governmental entities (like cities with over 100,000 residents or specific transit boards) to use two specific design-build methods for water and wastewater infrastructure projects. It permits either a "fixed price design-build" (single set price for design and construction) or "progressive design-build" (early design involvement with staged payments). The bill requires projects to be "single integrated" (e.g., a full water treatment plant system or a linear transit route), prohibiting aggregated contracts across multiple locations. It amends Texas Government Code sections to apply these methods to water/wastewater projects and takes effect September 1, 2025.
