§ 6. Construction plans; custody; approval; and procedure
notwithstanding local requirements. The office of general services shall
have the custody of all plans, specifications, books and records of such
office which pertain to architecture. The commissioner of general
services shall prepare the drawings and specifications for and supervise
the construction of all new buildings erected at the expense of the
state, except as otherwise provided by law; shall also prepare the
drawings and specifications for reconstruction and for all additions to
existing buildings, and for the alteration or improvement thereof, and
shall see that the materials furnished and the work performed in
constructing, reconstructing, altering or improving any such building
are in accordance with such drawings and specifications, and that the
interests of the state are fully protected.

Notwithstanding any inconsistent provisions of law, the commissioner
of general services may by rules delegate to the agency or department
having custody of any public building full responsibility for the
preparation of plans and specifications and the supervision of minor,
routine or uncomplicated construction, reconstruction, alteration,
improvement or repair of any such building, providing the value of such
work shall not exceed one hundred fifty thousand dollars.

All the provisions of this chapter that relate to state buildings
shall, insofar as may be practicable, also apply to the improvement of
grounds owned by the state.

No municipality of the state shall have power to modify or change
plans or specifications for the erection, reconstruction, alteration or
improvement of state buildings, or the construction, plumbing, heating,
lighting or other mechanical branch of work necessary to complete the
work in question, nor to require that any person, firm or corporation
employed on any such work shall perform said work in any other or
different manner than that provided by said contract and specifications,
nor to obtain any other or additional authority or permit from such
municipality, department or person as a condition of doing such work,
nor shall any condition whatever be imposed by any such municipality in
relation to the work under the supervision of the commissioner of
general services, but such work shall be under the sole control of such
commissioner in accordance with the drawings, plans, specifications and
contracts in relation thereto; and the doing of any such work for the
state by any person, firm or corporation in accordance with the terms of
such contract, plans or specifications shall not subject said person,
firm or corporation to any liability or penalty, civil or criminal,
other than as may be stated in such contract and specifications or
incidental to the proper enforcement thereof. The commissioner of
general services shall prepare necessary contracts, to be approved as to
form and execution by the attorney-general, which shall be used in all
work let by contract and no payment shall be made on any such contract
except upon official certificate of such commissioner after audit by the
comptroller.
