N.J. Stat. § 18A:64-70
All contracts or agreements for the purchase of goods and services, as distinct from contracts or agreements for the construction of buildings and other improvements, which require public advertisement for bids shall be awarded by the board of trustees to the responsible bidder whose bid, conforming to the invitation for bids, will be most advantageous to the State college, price and other factors considered, except that a bid may be disqualified due to prior negative experience pursuant to the provisions of section 10 of P.L. 2021, c. 417(C.18A:64-70.1).
Prior to the award of any contract or agreement which does not require public advertisement, the estimated cost of which is 20 percent or more of the amount set forth in this act or, commencing January 1, 1985, 20 percent of the amount determined by the Governor pursuant to subsection b. of section 3 of this act, the contracting agent shall, except in the case of professional services, solicit quotations therefor whenever practicable, and the award thereof shall be made, in accordance with section 3 of this article, on the basis of the quotation, conforming to the request for proposals, which is most advantageous to the State college, price and other factors considered; however, if the contracting agent deems it impractical to solicit competitive quotations or having sought the quotations determines that the award should not be made on that basis, the contracting agent shall file a statement of explanation of the reason or reasons therefor, which shall be placed on file with the purchase, contract, or agreement.
