N.Y. Comp. Codes R. & Regs. tit. 10, § 69-10.9
(h) Once the fund administrator receives from the enrollee or person authorized to act on the enrollee’s behalf a minimum of three acceptable bids from qualified contractors, the fund administrator shall evaluate the qualifications of each bidder and the content of each bid to determine whether each bid is acceptable. If less than three are submitted, a written explanation of why three accepted bids were not obtained must be provided, as well as a written explanation of how the determination was made that the one or two bids being considered are reasonably priced. In order to be acceptable, a bid must:
(i) If the two lowest bids are within 10 percent of each other, the enrollee or his or her legally authorized representative may choose one of the two lowest bids. If there is more than a 10 percent difference between the two lowest bids, the fund administrator shall choose the bid that represents the best overall value for the fund and the enrollee based on factors including not only the price offered by each bidder but also the quality, durability, extent of any warranties provided, and the safety of the product itself. The successful bidder will be notified after the fund administrator or a designee of the fund administrator:
(2) obtains the written consent of the enrollee or the person authorized to act on the enrollee’s behalf to have the installation done by that bidder.
If the enrollee or person authorized to act on the enrollee’s behalf disagrees with the fund administrator’s decision, the enrollee or person authorized to act on the enrollee’s behalf can request a review of the decision. The fund administrator will authorize payment to the successful bidder of no more than one-third of the accepted bid amount unless there are extenuating circumstances about which the fund administrator receives advance notice such as a project that can be completed in one day or involves the purchase of a product prior to installation.
