Amends public building construction and repair contracting requirements (GS 143-128), minority participation goals (GS 143-128.2), public purchasing contracting requirements (GS 143-129), local government informal bidding requirements (GS 143-131), and minimum bidding requirements for public building construction and repair projects (GS 143-132) by establishing a new GS 143-129(b1) to authorize price-match preferences for lowest responsible, responsive resident bidders. Preference may be given if the bid of the lowest responsible responsive resident bidder is no greater than 5% or $10,000, whichever is less, above the lowest responsive responsible nonresident bidder, and the resident bidder matches the nonresident bidder's price. Resident bidder is defined as a person or corporation legally authorized to perform construction or repair work or engage in the sale of goods or services in North Carolina, and has maintained a physical place of business within the county with at least one employee for a period of at least six months prior to the bid solicitation announcement. This local preference authorization only applies to Catawba County.
