2006 New York Code - Construction Contracts.

 
    §  1596-g.  Construction  contracts. The authority shall let contracts
  for construction in the same  manner,  so  far  as  practicable,  as  is
  provided  by  law  for  contracts  of  the  city,  except that where the
  estimated expense of a contract  does  not  exceed  twenty-five  hundred
  dollars,  such  contract  may  be  entered  into without public letting.
  Nothing in this section shall be construed to limit  the  power  of  the
  authority  to  do  any construction directly by the officers, agents and
  employees of the authority.
