Competitive bidding threshold
Formal competitive bidding is required for construction or repair work at or over $500,000, under G.S. §143-129.1 Work from $30,000 to $500,000 uses informal bidding.
Award standard
Contracts go to the lowest responsible bidder.1
Multiple-prime contracts (separate specifications)
For building projects over $300,000, G.S. §143-128 requires separate specifications for four branches — HVAC, plumbing and gas, electrical, and general work — and authorizes separate-prime, single-prime, or dual bidding.2
Performance and payment bonds are required for contracts over $50,000 on projects costing more than $300,000.
Prevailing wage
North Carolina has no state prevailing-wage law. Federal Davis-Bacon rates apply only to federally funded work.
Document distribution & addenda
North Carolina DOT issues addenda to all bidders and applies a 10-day rule under which an addendum issued within ten days of bid opening extends the bid date.3
An addendum issued within ten days of bid opening triggers NCDOT's 10-day rule extending the bid date.
