N.M. Stat. § 67-3-43
The state highway department may construct, reconstruct and maintain all state highways by work done with its own forces or let the work on contract after advertising for bids subject to the approval of the state highway commission. Such advertisement for bids shall be in accordance with the rules and regulations adopted therefor by the commission, and bids shall be received at such places and shall be made on such forms and in such manner and accompanied by such guarantee as may be prescribed by the commission. The chief highway administrator may reject any or all bids if they are unbalanced or for any other good reason, but otherwise he shall award the contract to the lowest responsible bidder allowing for such preference as may be provided by law. The successful bidder is required to furnish satisfactory bond in such amount as may be determined by the commission. The commission may adopt rules and regulations providing for the exclusion of contractors from bidding and for the determination of a responsible bidder pursuant to the provisions of the Public Purchases Act.
