§ 136. Contracts in pursuance of appropriations. A contract or
contracts made in pursuance of an appropriation by the state for a
specific object shall be for the completion of the work contemplated by
the appropriation, and in the aggregate shall not exceed the amount of
such appropriation. A contract for a part of such work shall not be
binding upon the state until contracts are also made covering the entire
work contemplated by such appropriation, except that, (a) upon
certification by the agency having jurisdiction to the state comptroller
that sufficient appropriations remain for completion of the entire work
contemplated, preliminary work such as site preparation and
infrastructure work may be commenced for a project where the timeliness
thereof is of the essence and the director of the budget certifies to
such need and to the availability of appropriations, and except (b)
where it is expressly provided by such appropriation that a part of the
work may be done by day's labor. Except as provided in section
thirty-eight of the highway law, every such contract shall be
accompanied by a bond for the completion of the work, specified in the
contract, within the amount stipulated therein, which bond shall be
filed in the office of the state comptroller.
