(a) Subject to the provisions of subsections (b), (c), (d), (e), (f), (g) and (h) and K.S.A. 16-1804 and 16-1805, and amendments thereto, all persons who enter into a contract for private construction after the effective date of this act, shall make all payments pursuant to the terms of the contract.
(b) The following provisions in a contract for private construction shall be against public policy and shall be void and unenforceable:
(1) A provision that purports to waive, release or extinguish the right to resolve disputes through litigation in court or substantive or procedural rights in connection with such litigation except that a contract may require binding arbitration as a substitute for litigation or require non-binding alternative dispute resolution as a prerequisite to litigation;
(2) a provision that purports to waive, release or extinguish rights provided by article 11 of chapter 60 of the Kansas Statutes Annotated, and amendments thereto, except that a contract may require a contractor or subcontractor to provide a waiver or release of such rights as a condition for payment, but only to the extent of the amount of payment received; and
(3) a provision that purports to waive, release or extinguish rights of subrogation for losses or claims covered or paid by liability or workers compensation insurance except that a contract may require waiver of subrogation for losses or claims paid by a consolidated or wrap-up insurance program, owners and contractors protective liability insurance, or project management protective liability insurance, unless otherwise prohibited under subsection (b)(5) of K.S.A. 2009 Supp. 40-5403, and amendments thereto.
(c) Any provision in a contract for private construction providing that a payment from a contractor or subcontractor to a subcontractor is contingent or conditioned upon receipt of a payment from any other private party, including a private owner, is no defense to a claim to enforce a mechanic’s lien or bond to secure payment of claims pursuant to the provisions of article 11 of chapter 60 of the Kansas Statutes Annotated, and amendments thereto.
(d) All contracts for private construction shall provide that payment of amounts due a contractor from an owner, except retainage, shall be made within 30 days after the owner receives a timely, properly completed, undisputed request for payment.
(e) If the owner fails to pay a contractor within 30 days following receipt of a timely, properly completed, undisputed request for payment, the owner shall pay interest to the contractor beginning on the thirty-first day after receipt of the request for payment, computed at the rate of 18% per annum on the undisputed amount.
(f) A contractor shall pay its subcontractors any amounts due within seven business days of receipt of payment from the owner, including payment of retainage, if retainage is released by the owner, if the subcontractor has provided a timely, properly completed and undisputed request for payment to the contractor.
(g) If the contractor fails to pay a subcontractor within seven business days, the contractor shall pay interest to the subcontractor beginning on the eighth business day after receipt of payment by the contractor, computed at the rate of 18% per annum on the undisputed amount.
(h) The provisions of subsections (f) and (g) shall apply to all payments from subcontractors to their subcontractors.
