2006 New York Code - Separate Specifications For Contract Work For The State.

 
    § 135. Separate specifications for contract work for the state.  Every
  officer,  board, department, commission or commissions, charged with the
  duty of preparing specifications or awarding or entering into  contracts
  for  the  erection,  construction  or  alteration  of buildings, for the
  state, when the entire cost of such work  shall  exceed  fifty  thousand
  dollars,  must  have  prepared  separate  specifications for each of the
  following three subdivisions of the work to be performed:
    1. Plumbing and gas fitting.
    2. Steam heating, hot water heating, ventilating and air  conditioning
  apparatus.
    3. Electric wiring and standard illuminating fixtures.
    Such  specifications  must  be  so  drawn  as  to  permit separate and
  independent bidding upon each of the above three subdivisions  of  work.
  All  contracts  hereafter  awarded  by the state or a department, board,
  commissioner or officer  thereof,  for  the  erection,  construction  or
  alteration  of  buildings,  or  any  part thereof, shall award the three
  subdivisions of the above specified work separately to  responsible  and
  reliable  persons,  firms  or  corporations  engaged in these classes of
  work.  A contract for one or more buildings  in  any  project  shall  be
  awarded  to the lowest responsible bidder for all the buildings included
  in the specifications.
    Nothing in this section shall be construed to prevent the  authorities
  in  charge  of  any state building, from performing any such branches of
  work by or through their regular employees, or in  the  case  of  public
  institutions, by the inmates thereof.
