N.Y. Public Authorities Law § 1209
2. Any purchase contract, including but not limited to contracts for the purchase of equipment, materials or supplies, the estimated cost of which exceeds the sum of ten thousand dollars, shall be made by the authority only upon public letting founded on sealed bids, except in a case where the authority, by resolution, declares the existence of an emergency or the existence of other circumstances making competitive bidding impracticable or inappropriate, except in no instance other than in circumstances such as described in paragraph (g) hereof, shall the authority declare that competitive bidding is inappropriate with respect to purchase contracts for omnibuses. In each instance when the authority declares competitive bidding inappropriate it shall state the reasons therefor. Competitive bidding may be declared inappropriate by the authority in instances (a) where the item to be purchased is available only from a single source; or (b) where professional engineering or architectural services are solicited; or (c) where only a single bid is received in response to an invitation for competitive bids; or (d) where the authority has chosen to standardize a component on the basis of compatibility or maintenance reliability; or (e) where the apparent low bidder is declared by the authority to be not qualified to perform the terms of the contract; or (f) where the authority wishes to experiment with or test a new product or technology or evaluate the service or reliability of a new source for a particular product or component; or (g) where the authority by a vote of two-thirds of its members then in office determines that its prior experience with a potential source or contractor has been such as to require, in the public interest, that such source or contractor not be considered eligible to bid and that after the elimination of said source or contractor from the bidding process there would effectively remain only a single source for the item to be purchased and the authority purchases the item from such source; or (h) where the authority by a two-thirds vote of its members determines, on the basis of its analysis of the competitive situation among potential sources for the item to be purchased, is such that it is in the public interest to encourage new sources of manufacture or supply by awarding a contract by negotiation and without competitive bidding. Notice of the invitation for such bidding shall state the time and place of the receipt and opening of bids and shall be published in the city record in five successive issues at least ten days preceding such opening. The authority may reject all such bids and readvertise for new bids if it shall deem it for the public interest so to do. If not, it shall award the contract to the lowest responsible bidder unless the authority, by unanimous vote, shall determine that it is for the public interest that a bid other than that of the lowest responsible bidder shall be accepted. * 3. A contract for the purchase of rapid transit cars or components of rapid transit cars in furtherance or implementation of a capital program plan approved pursuant to section twelve hundred sixty-nine-b of this article may also be awarded by the authority by negotiation without competitive bidding provided the following standards and procedures are complied with:
4. Notwithstanding the provisions of subdivision two of this section, a contract for the purchase of omnibuses or components of omnibuses in furtherance or implementation of a capital program plan approved pursuant to section twelve hundred sixty-nine-b of this article may also be awarded by the authority by negotiation without competitive bidding provided the following standards and procedures are complied with:

(f) the authority determines that it is in the public interest to award contracts pursuant to a process for competitive request for proposals as hereinafter set forth. For purposes of this section, a process for competitive request for proposals shall mean a method of soliciting proposals and awarding a contract on the basis of a formal evaluation of the characteristics, such as quality, cost, delivery schedule and financing of such proposals against stated selection criteria. Public notice of the requests for proposals shall be given in the same manner as provided in subdivision eight of this section and shall include the selection criteria. In the event the authority makes a material change in the selection criteria from those previously stated in the notice, it will inform all proposers of such change and permit proposers to modify their proposals.
(g) the authority issues a competitive request for proposals pursuant to the procedures of paragraph (f) of this subdivision for the purchase or rehabilitation of rapid transit cars and omnibuses. Any such request may include among the stated selection criteria the performance of all or a portion of the contract at sites within the state of New York or the use of goods produced or services provided within the state of New York, provided however that in no event shall the authority award a contract to a manufacturer whose final offer, as expressed in unit cost is more than ten percent higher than the unit cost of any qualified competing final offer, if the sole basis for such award is that the higher priced offer includes more favorable provision for the performance of the contract within the state of New York or the use of goods produced or services provided within the state of New York, and further provided that the authority's discretion to award a contract to any manufacturer shall not be so limited if a basis for such award, as determined by the authority, is superior financing, delivery schedule, life cycle, reliability, or any other factor the authority deems relevant to its operations.
