Conn. Gen. Stat. § 4b-28

(b) Each state agency, commission or department, except the Department of Transportation, that plans to construct or enlarge a building or underground utility facility, which project has an estimated cost of one hundred thousand dollars or more, shall give written notice to the chief executive officer of the town, city or borough in which such project is planned, and to the members of the General Assembly representing such town, city or borough, not later than sixty days before advertising for bids for such project. If a state agency, commission or department plans to do such construction or enlargement itself, it shall give such notice not later than sixty days before beginning the work. Notwithstanding the provisions of this subsection, if the executive authority of the agency, commission or department determines that an emergency exists or that compliance with the provisions of this subsection would increase the cost of the construction or enlargement project, such agency, commission or department shall give such notice as soon as practicable. As used in this section, “executive authority” shall be construed as defined in section 4-37e . The provisions of this section shall not apply to a community-based residential facility for individuals with intellectual disability or persons with psychiatric disabilities.
