(a) Every contract subject to this chapter shall include plans and specifications detailing all labor and materials to be furnished thereunder. Such specifications shall have a separate section for each of the following classes of work if, in the estimate of the awarding authority, the class of work will exceed one hundred thousand dollars: (1) Masonry work; (2) electrical work; (3) plumbing; and (4) heating, ventilating and air conditioning work. Such specifications shall also have a separate section for each other class of work for which the awarding authority deems it necessary or convenient.

(b) Each separate section in the specifications provided for by this section shall specify by number each sheet of plans showing work to be done by the subcontractor under such section, and shall require the subcontractor to install all materials to be furnished by him under such section other than materials which, in the opinion of the awarding authority, it is not customary under current trade practices for such subcontractor to install and the installation of which is expressly required by another section of the specifications. Each class of work set forth in a separate section of the specifications pursuant to this section shall be a subtrade designated in the general bid form and shall be the matter of a subcontract made in accordance with the procedure set forth in this chapter.

(c) Whenever the awarding authority has designated a separate section for a class of work, under subsection (a) of this section, the general contractor shall, when applicable, state as part of its application for partial payment that it considers the work required to be done under any such separate section to be fully completed in accordance with the terms of the contract. The awarding authority shall thereupon conduct an inspection of the work in such class, and if it finds that such work has been fully completed in accordance with the terms of the contract, it shall issue a statement certifying that such work is accepted as fully completed, and shall pay the general contractor in full for such work.
