Competitive bidding threshold

Public construction over $100,000 generally requires formal competitive sealed bidding under A.R.S. §34-201.1 Smaller projects may use informal or simplified procedures under the agency's rules.

Award standard

Contracts go to the lowest responsible bidder.2

Multiple-prime contracts

Arizona 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

Arizona has no state prevailing-wage law — and goes further: A.R.S. §34-321 prohibits the state and its political subdivisions from requiring prevailing wages on public works contracts.3 Federal Davis-Bacon rates still apply to federally funded work.

Document distribution & addenda

Arizona DOT §102.07 requires any interpretation to be issued as an addendum furnished to all prospective bidders before the time set for opening proposals.4

Record of change

Arizona not only lacks a state prevailing-wage law — A.R.S. §34-321 bars state agencies and local governments from requiring prevailing wage on public works. Public construction over $100,000 must be formally bid.
