Conn. Gen. Stat. § 4b-102

(b) The Commissioner of Administrative Services shall give notice to bidders prequalified pursuant to subsection (a) of this section of the time and place where the public letting shall occur and shall include in the notice such information concerning the required work as appropriate. Each bid shall be kept sealed until opened publicly at the time and place as set forth in the notice soliciting such bid. The commissioner shall not award any construction contract after public letting, except to the responsible qualified bidder, submitting the lowest bid in compliance with the bid requirements. The commissioner may waive any minor irregularity in a bid, and may either reject all bids and again advertise for bids, or, if he deems it advisable, negotiate with other contractors who submitted bids in ascending order of bid prices without change in the contract, specifications, plans and other requirements.

(c) The invitation to bid on the construction contract awarded by the Commissioner of Administrative Services pursuant to this section shall contain such other terms and conditions and such provisions for penalties, as the commissioner deems appropriate.

(d) The Commissioner of Administrative Services shall require, for the protection of the state and the Connecticut State University System, such deposits, bonds and security in connection with the submission of bids, the awarding of construction contracts and the performance of work as the commissioner determines appropriate and in the public interest of the state.
