2021 New York Laws SCC - Second Class Cities Article 8 - Department of Contract and Supply 120 - Board of Contract and Supply.

§ 120. Board  of  contract  and  supply.  There  shall  be  a board of   contract and supply, composed of the mayor, comptroller, commissioner of   public works, corporation counsel and city engineer. Except as otherwise   provided by law, it shall be the duty of such board, after public notice   and in accordance with regulations to be prescribed by general ordinance   of the common council, to let  to  the  lowest  bidder,  who  will  give   adequate  security  therefor,  all  contracts for the performance of any   work or for the supply of any material required by or for the use of any   officer, board, body or department of the city, in all cases  where  the   expense of such work or materials, or both, shall exceed the sum of five   hundred  dollars, unless by ordinance of the common council adopted by a   vote of not less  than  four-fifths  of  all  the  members  thereof  and   unanimously  approved  by the board of estimate and apportionment, it is   determined that a public emergency exists in which case  said  ordinance   shall  state  the  circumstances  and conditions that created the public   emergency, which shall be limited to those arising out of an accident or   other unforeseen occurrence or  condition  affecting  public  buildings,   public  property  or  the  life,  health,  safety  or  property  of  the   inhabitants of such city require immediate  action  which  cannot  await   public  bidding, and shall designate the officer, board or department to   procure such  work  or  purchase  such  materials.  In  case  of  public   emergency  involving  accident  or  other injury by which the heating or   plumbing of  any  of  the  public  buildings  or  any  of  the  fire  or   water-works  apparatus  or any of the machinery used in sewage-treatment   plants,  or  for  garbage  disposal,  or  any  equipment  used  by   the   water-works  or  department  of  public works shall become disabled, the   commissioner having jurisdiction thereof shall cause repairs thereto  to   be  made  without  a  letting by contract, upon filing with the board of   contract and supply a certificate, approved by the mayor,  showing  such   emergency and the necessity for such repairs. The board shall have power   to  reject  all  bids  or  proposals if in its opinion the lowest bid or   proposal is excessive. The said  notice  shall  describe  the  work  and   materials for which contracts will be let and the day and hour and place   of  the meeting of the board at which proposals therefor will be opened.   Specifications for the performance of any work and for the supply of any   materials shall be prepared and set forth  with  sufficient  details  to   inform  all  persons proposing to bid therefor of the nature of the work   to be done and of the materials to be supplied, and written  or  printed   copies  thereof  shall  be  delivered  to all applicants therefor. Every   contract for a public improvement shall be based upon an estimate of the   whole cost  thereof,  including  all  expenses  incidental  thereto  and   connected  therewith,  to  be  furnished by the proper officer, board or   department having charge of such improvements. No bid or proposal  shall   be  received  or contract awarded, other than for a local improvement or   work to be performed by the city, which  involves  the  construction  or   maintenance  of  any  structure,  erection,  obstruction  or  excavation   within, under, over, along or upon any street or public place within the   city, unless the person to whom such contract  shall  be  awarded  shall   have a franchise permitting the same.
