Conn. Gen. Stat. § 4e-48

(b) Notwithstanding any provision of law, in the award of a contract, after the original bids have been received and an original lowest responsible qualified bid is identified, a state contracting agency shall add a per cent increase to the original bid of a nonresident bidder equal to the per cent, if any, of the preference given to such nonresident bidder in the state in which such nonresident bidder resides. If, after application of such per cent increase, the bidder that submits the lowest responsible qualified bid is a resident bidder, the state contracting agency shall award such contract to such resident bidder provided such resident bidder agrees, in writing, to meet the original lowest responsible qualified bid. Any such agreement by such resident bidder to meet the original lowest responsible qualified bid shall be made not later than seventy-two hours after such resident bidder receives notice from such state contracting agency that such resident bidder may be awarded such contract if such resident bidder agrees to meet the original lowest responsible qualified bid.

(c) Not later than January 1, 2009, and each January thereafter, the State Contracting Standards Board shall publish a list of states that give preference to in-state bidders with the per cent increase applied in each state. Such list shall be made available to all state contracting agencies and may be relied upon by such agencies in determining the lowest responsible bidder.
