Conn. Gen. Stat. § 49-42
(a)(1) Any person who performed work or supplied materials for which a requisition was submitted to, or for which an estimate was prepared by, the awarding authority and who does not receive full payment for such work or materials within sixty days of the applicable payment date provided for in subsection (a) of section 49-41a, or any person who supplied materials or performed subcontracting work not included on a requisition or estimate who has not received full payment for such materials or work within sixty days after the date such materials were supplied or such work was performed, may enforce such person's right to payment under the bond by serving a notice of claim on the surety that issued the bond and a copy of such notice to the contractor named as principal in the bond not later than one hundred eighty days after the last date any such materials were supplied or any such work was performed by the claimant. For the payment of retainage, as defined in section 42-158i, such notice shall be served not later than one hundred eighty days after the applicable payment date provided for in subsection (a) of section 49-41a. The notice of claim shall state with substantial accuracy the amount claimed and the name of the party for whom the work was performed or to whom the materials were supplied, and shall provide a detailed description of the bonded project for which the work or materials were provided. If the content of a notice prepared in accordance with subsection (c) of section 49-41a complies with the requirements of this section, a copy of such notice, served not later than one hundred eighty days after the date provided for in this section upon the surety that issued the bond and upon the contractor named as principal in the bond, shall satisfy the notice requirements of this section. Not later than ninety days after service of the notice of claim, the surety shall make payment under the bond and satisfy the claim, or any portion of the claim which is not subject to a good faith dispute, and shall serve a notice on the claimant denying liability for any unpaid portion of the claim. The surety's failure to discharge its obligations under this section shall not be deemed to constitute a waiver of defenses the surety or its principal on the bond may have or acquire as to the claim, except as to undisputed amounts for which the surety and claimant have reached agreement. If, however, the surety fails to discharge its obligations under this section, then the surety shall indemnify the claimant for the reasonable attorneys' fees and costs the claimant incurs thereafter to recover any sums found due and owing to the claimant. The notices required under this section shall be served by registered or certified mail, postage prepaid in envelopes addressed to any office at which the surety, principal or claimant conducts business, or in any manner in which civil process may be served.
