(1) Bid Security.
(2) Contract Performance Payment Bonds.
(a) When Required-Amounts. The following bonds or security must be delivered to the governmental body and become binding on the parties upon the execution of the contract for construction:
(c) Suits on Payment Bonds-Right to Institute. A person who has furnished labor, material, or rental equipment to a bonded contractor or his subcontractors for the work specified in the contract, and who has not been paid in full for it before the expiration of a period of ninety days after the day on which the last of the labor was done or performed by the person or material or rental equipment was furnished or supplied by the person for which the claim is made, has the right to sue on the payment bond for the amount, or the balance of it, unpaid at the time of institution of the suit and to prosecute the action for the sum or sums justly due the person. A remote claimant has a right of action on the payment bond only upon giving written notice to the contractor within ninety days from the date on which the person did or performed the last of the labor or furnished or supplied the last of the material or rental equipment upon which the claim is made, stating with substantial accuracy the amount claimed as unpaid and the name of the party to whom the material or rental equipment was furnished or supplied or for whom the labor was done or performed. The written notice to the bonded contractor must be served personally or served by mailing the notice by registered or certified mail, postage prepaid, in an envelope addressed to the bonded contractor at any place the bonded contractor maintains a permanent office for the conduct of its business, or at the current address as shown on the records of the Department of Labor, Licensing and Regulation. The aggregate amount of a claim against the payment bond by a remote claimant may not exceed the amount due by the bonded contractor to the person to whom the remote claimant has supplied labor, materials, rental equipment, or services, unless the remote claimant has provided notice of furnishing labor, materials, or rental equipment to the bonded contractor. The written notice to the bonded contractor must be served personally or sent by fax or by electronic mail or by registered or certified mail, postage prepaid, to the bonded contractor at any place the bonded contractor maintains a permanent office for the conduct of its business, or at the current address as shown on the records of the Department of Labor, Licensing and Regulation. After receiving the notice of furnishing labor, materials, or rental equipment, payment by the bonded contractor may not lessen the amount recoverable by the remote claimant. The aggregate amount of claims on the payment bond may not exceed the penal sum of the bond.
A suit under this section must not be commenced after the expiration of one year after the last date of furnishing or providing labor, services, materials, or rental equipment.
For purposes of this section, "bonded contractor" means the contractor or subcontractor furnishing the payment bond, and "remote claimant" means a person having a direct contractual relationship with a subcontractor of a bonded contractor, but no expressed or implied contractual relationship with the bonded contractor.
