The Contracting Officer may instruct the Contractor to remove deteriorated framing members and replace them with new. The extent of deteriorated framing members to be removed and replaced shall be determined and authorized by the Contracting Officer. Do not proceed with removal operations until the quantity of framing to be removed has been established.

2.4.4 Temporary Roofing

Install temporary roofing and flashing as necessary to maintain a watertight condition throughout the course of the work. Remove temporary work prior to installation of permanent roof system materials unless approved otherwise by the Contracting Officer.

2.4.5 SOFFIT, FASCIA, AND SUBFASCIA: The Contracting Officer shall determine the amount and location of soffit, fascia, and subfascia to be removed and replaced with new, as well as the extent of overhang to be removed. To remove overhang, shorten rafter tails and remove section of roof deck as required.
