Provide <br />protection from adverse weather conditions for portions of Project that might be exposed during cutting <br />and patching operations. <br />E.Existing Utility Services and Mechanical/Electrical Systems: Where existing services/systems are <br />required to be removed, relocated, or abandoned, bypass such services/systems before cutting to prevent <br />interruption to occupied areas. <br />F.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 adjoining <br />construction. If possible, review proposed procedures with original Installer; comply with original <br />Installer's written recommendations. <br />1.In general, use hand or small power tools designed for sawing and grinding, not hammering and <br />chopping. Cut holes and slots neatly to minimum size required, and with minimum disturbance of <br />adjacent surfaces. Temporarily cover openings when not in 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 diamond-core <br />drill. <br />4.Excavating and Backfilling: Comply with requirements in applicable Sections where required by <br />cutting and patching operations. <br />5.Mechanical and Electrical Services: Cut off pipe or conduit in walls or partitions to be removed. <br />Cap, valve, or plug and seal remaining portion of pipe or conduit to prevent entrance of moisture <br />or other foreign matter after cutting. <br />6. Proceed with patching after construction operations requiring cutting are complete. <br />G.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 practicable, as <br />judged by Architect. Provide materials and comply with installation requirements specified in other <br />Sections, where applicable. <br />1.Inspection: Where feasible, test and inspect patched areas after completion to demonstrate <br />physical integrity of installation. <br />2.Exposed Finishes: Restore exposed finishes of patched areas and extend finish restoration into <br />retained adjoining construction in a manner that will eliminate evidence of patching and <br />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 />3.Floors and Walls: Where walls or partitions that are removed extend one finished area into <br />another, patch and repair floor and wall surfaces in the new space. Provide an even surface of <br />uniform finish, color, texture, and appearance. Remove in-place floor and wall coverings and <br />replace with new materials, if necessary, to achieve uniform color and appearance. <br />a.Where patching occurs in a painted surface, prepare substrate and apply primer and <br />intermediate paint coats appropriate for substrate over the patch, and apply final paint coat <br />over entire unbroken surface containing the patch, corner to corner of wall and edge to <br />edge of ceiling. Provide additional coats until patch blends with adjacent surfaces. <br />4.Ceilings: Patch, repair, or rehang in-place ceilings as necessary to provide an even-plane surface <br />of uniform appearance. <br />5.Exterior Building Enclosure: Patch components in a manner that restores enclosure to a <br />weathertight condition and ensures thermal and moisture integrity of building enclosure. <br />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
