(1) Each contract for construction services between a public entity and a contractor must provide for the development of a list of items and the estimated cost to complete each item on the list required to render complete, satisfactory, and acceptable the construction services purchased by the public entity. The contract must specify the process for the development of the list and for determining the cost to complete each item on the list, and should include the responsibilities of the public entity and the contractor in developing and reviewing the list and a reasonable time for developing the list, as follows:(a) For construction projects having an estimated cost of less than $10 million, within 30 calendar days after reaching substantial completion of the construction services purchased as defined in the contract, or, if not defined in the contract, upon reaching beneficial occupancy or use; or
(b) For construction projects having an estimated cost of $10 million or more, within 30 calendar days, unless otherwise extended by contract not to exceed 45 calendar days, after reaching substantial completion of the construction services purchased as defined in the contract, or, if not defined in the contract, upon reaching beneficial occupancy or use.
(2) If the contract between the public entity and the contractor relates to the purchase of construction services on more than one building or structure, or involves a multiphased project, the contract must provide for the development of a list of items required to render complete, satisfactory, and acceptable all the construction services purchased pursuant to the contract for each building, structure, or phase of the project within the time limitations provided in subsection (1).
(3) The failure to include any corrective work or pending items not yet completed on the list developed pursuant to subsection (1) or subsection (2) does not alter the responsibility of the contractor to complete all the construction services purchased pursuant to the contract.
(4) Within 20 business days after developing the list, and after receipt of a proper invoice or payment request, the public entity must pay the contractor the remaining balance of the contract, including any remaining retainage withheld by the public entity pursuant to s. 255.078, less an amount equal to 150 percent of the estimated cost to complete the items on the list. (5) Upon completion of all items on the list, the contractor may submit a payment request for all remaining retainage withheld by the public entity pursuant to s. 255.078. If a good faith dispute exists as to whether one or more items identified on the list have been completed pursuant to the contract, the public entity may continue to withhold an amount not to exceed 150 percent of the total costs to complete such items. (6) All items that require correction under the contract and that are identified after the preparation and delivery of the list remain the obligation of the contractor as defined by the contract.
(7) Warranty items may not affect the final payment of retainage as provided in this section or as provided in the contract between the contractor and its subcontractors and suppliers.
(8) Retainage may not be held by a public entity or a contractor to secure payment of insurance premiums under a consolidated insurance program or series of insurance policies issued to a public entity or a contractor for a project or group of projects, and the final payment of retainage as provided in this section may not be delayed pending a final audit by the public entity’s or contractor’s insurance provider.
(9) If a public entity fails to comply with its responsibilities to develop the list required under subsection (1) or subsection (2), as defined in the contract, within the time limitations provided in subsection (1), the contractor may submit a payment request for all remaining retainage withheld by the public entity pursuant to s. 255.078 and the public entity must pay the contractor all remaining retainage previously withheld within 20 days after receipt of the payment request. The public entity is not required to pay or process any payment request for retainage if the contractor has failed to cooperate with the public entity in the development of the list or failed to perform its contractual responsibilities, if any, with regard to the development of the list or if s. 255.078(3) applies.
