Authorizes the Department of Transportation to enter into a progressive design-build contract for a certain project. (BDR S-626)

SB 315 authorizes Nevada's Department of Transportation (DOT) to use a "progressive design-build" contracting method for improvements to Interstate 80 East between Vista Boulevard in Sparks and USA Parkway (State Route 439) in Storey County. This allows the DOT to first contract for preconstruction services (like design and cost estimation), then later negotiate final construction contracts with the same team if design progress meets cost and timeline requirements. The bill requires the DOT to advertise solicitations online, use specified one-step or two-step procurement processes for bids, and permits negotiation for preconstruction services before final construction. It directly affects the DOT, potential contractors bidding on this highway project, and the public using the I-80 East corridor.
