(2)Whenever a contractor receives payment pursuant to this section, the contractor shall make payments to each of his subcontractors of any amounts actually received which were included in the contractor’s request for payment to the public entity for such subcontracts. The contractor shall make such payments within seven calendar days of receipt of payment from the public entity in the same manner as the public entity is required to pay the contractor under this section if the subcontractor is satisfactorily performing under his contract with the contractor. The subcontractor shall pay all suppliers, sub-subcontractors, laborers, and any other persons who provide goods, materials, labor, or equipment to the subcontractor any amounts actually received which were included in the subcontractor’s request for payment to the contractor for such persons, in the same manner set forth in this subsection (2) regarding payments by the contractor to the subcontractor. If the subcontractor fails to make such payments in the required manner, the subcontractor shall pay said suppliers, sub-subcontractors, and laborers interest in the same manner set forth in this subsection (2) regarding payments by the contractor to the subcontractor. At the time the subcontractor submits a request for payment to the contractor, the subcontractor shall also submit to the contractor a list of the subcontractor’s suppliers, sub-subcontractors, and laborers. The contractor shall be relieved of the requirements of this subsection (2) regarding payment in seven days and interest payment until the subcontractor submits such list. If the contractor fails to make timely payments to the subcontractor as required by this section, the contractor shall pay the subcontractor interest as specified by contract or at the rate of fifteen percent per annum whichever is higher, on the amount of the payment which was not made in a timely manner. The interest shall accrue for the period from the required payment date to the date on which payment is made. Nothing in this subsection (2) shall be construed to affect the retention provisions of any contract.
