New York Consolidated Laws, Public Authorities Law - PBA § 1599-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.
