Competitive bidding threshold

Public works construction over $250,000 must be procured by competitive sealed bidding under Idaho Code §67-2805.1 Projects from $100,000 to $250,000 may use an informal quote process. Bidders must hold the requisite public-works contractor license; Category B projects add a prequalification stage.

Award standard

Contracts go to the qualified bidder submitting the lowest responsive bid.1

Multiple-prime contracts

Idaho has no statewide multiple-prime mandate. Unlike New York's Wicks Law or Pennsylvania's Separations Act, a single general contract is permitted.

Prevailing wage

Idaho has no state prevailing-wage law. Federal Davis-Bacon rates apply only to federally funded work.

Document distribution & addenda

Idaho Transportation Department §102 requires addenda to be uploaded to QuestCDN with all plan holders notified to download them, and acknowledgment of each addendum in the proposal.3
