§ 19. Manner of doing work or acquiring material. The work of
construction, reconstruction, alteration, repair or improvement of any
state building, whether constructed or to be constructed, may be done by
the employment of incarcerated individuals or outside labor or both and
by the purchase of materials in the open market whenever in the opinion
of the department having jurisdiction over such building, and the
commissioner of general services or his or her authorized
representative, such a course shall be deemed advantageous to the state,
and only upon plans and specifications prepared by the commissioner of
general services, but no compensation shall be allowed for the
employment of incarcerated individual labor except convict labor.
