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
