Temporary Support: Provide temporary support of Work to be cut. <br />D. Protection: Protect in-place construction during cutting and patching to prevent damage. <br />Provide protection from adverse weather conditions for portions of Project that might be <br />exposed during cutting and patching operations. <br />E. Adjacent Occupied Areas: Where interference with use of adjoining areas or interruption of <br />free passage to adjoining areas is unavoidable, coordinate cutting and patching in accordance <br />with requirements in Section 011000 "Summary." <br />F. Existing Utility Services and Mechanical/Electrical Systems: Where existing services/systems <br />are required to be removed, relocated, or abandoned, bypass such services/systems before <br />cutting to minimize interruption to occupied areas. <br />G. Cutting: Cut in-place construction by sawing, drilling, breaking, chipping, grinding, and similar <br />operations, including excavation, using methods least likely to damage elements retained or <br />adjoining construction. If possible, review proposed procedures with original Installer; comply <br />with original Installer's written recommendations. <br />1. In general, use hand or small power tools designed for sawing and grinding, not <br />hammering and chopping. Cut holes and slots neatly to minimum size required, and with <br />minimum disturbance of adjacent surfaces. Temporarily cover openings when not in <br />use. <br />2. Finished Surfaces: Cut or drill from the exposed or finished side into concealed surfaces. <br />3. Concrete and Masonry: Cut using a cutting machine, such as an abrasive saw or a <br />diamond-core drill. <br />4. Excavating and Backfilling: Comply with requirements in applicable Sections where <br />required by cutting and patching operations. <br />5. Proceed with patching after construction operations requiring cutting are complete. <br />H. Patching: Patch construction by filling, repairing, refinishing, closing up, and similar operations <br />following performance of other Work. Patch with durable seams that are as invisible as <br />practicable, as judged by Engineer. Provide materials and comply with installation <br />requirements specified in other Sections, where applicable. <br />1. Inspection: Where feasible, test and inspect patched areas after completion to <br />demonstrate physical integrity of installation. <br />2. Exposed Finishes: Restore exposed finishes of patched areas and extend finish <br />restoration into retained adjoining construction in a manner that will eliminate evidence <br />of patching and refinishing. <br />a. Clean piping, conduit, and similar features before applying paint or other finishing <br />materials. <br />b. Restore damaged pipe covering to its original condition. <br />DocuSign Envelope ID: 0844D1D6-E311-4FC5-8B5B-BB1E27A908ED
