SECTION 1. Chapter 30 of the General Laws is hereby amended by adding the following section:-

Section 39U. Payment for Work Not Included in the Original Contract

Every contract subject to section 44A of chapter 149 or subject to section 39M of chapter 30 or subject to chapter 149A, and every subcontract or trade contract as applicable, shall provide a reasonable time period within which a written request submitted by a person seeking an increase in the contract price shall be approved or rejected, whether in whole or in part. The time period shall not exceed 30 days after the later of commencement of the performance of the work on which the request is based or submission of the written request; provided, however, that the time period, as applicable to approval or rejection by the person at each tier of contract below the owner of the project, may be extended by 7 days more than the time period applicable to the person at the tier of contract above the person. A request which is neither approved nor rejected within such time period shall be deemed to be approved and may be submitted for payment within the next application for a periodic progress payment, unless it is rejected before the date payment if due. A rejection of a request, whether in whole or in part, shall be made in writing, shall include an explanation of the factual and contractual basis for the rejection and shall be certified as made in good faith. A rejection of a request shall be subject to the applicable dispute resolution procedure. A provision in the contract which requires a party to delay commencement of the procedure until a date later than 60 days after the rejection shall be void and unenforceable.
