General: Employ skilled workers to perform cutting and patching. Proceed with cutting and patching at the earliest <br /> feasible time, and complete without delay. <br /> 1. Cut existing construction to provide for installation of other components or performance of other construction, <br /> and subsequently patch as required to restore surfaces to their original condition. <br /> B. Cutting: Cut existing construction by sawing, drilling, breaking, chipping, grinding, and similar operations, including <br /> excavation, using methods least likely to damage elements retained or adjoining construction. If possible, review <br /> proposed procedures with original Installer; comply with original Installer's written recommendations. <br /> 1. In general, use hand or small power tools designed for sawing and grinding, not hammering and chopping. <br /> Cut holes and slots as small as possible, neatly to size required, and with minimum disturbance of adjacent <br /> surfaces. Temporarily cover openings when not in use. <br /> 2. Existing 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 drill. <br /> 4. Excavating and Backfilling: Comply with requirements in applicable Division 31 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. Cap, valve, or <br /> plug and seal remaining portion of pipe or conduit to prevent entrance of moisture or other foreign matter after <br /> cutting. <br /> 6. Proceed with patching after construction operations requiring cutting are complete. <br /> C. Patching: Patch construction by filling, repairing, refinishing, closing up, and similar operations following <br /> performance of other Work. Patch with durable seams that are as invisible as possible. Provide materials and <br /> comply with installation requirements specified in other Sections of these Specifications. <br /> 1. Inspection: Where feasible, test and inspect patched areas after completion to demonstrate integrity of <br /> installation. <br /> 2. Exposed Finishes: Restore exposed finishes of patched areas and extend finish restoration into retained <br /> adjoining construction in a manner that will eliminate evidence of patching and refinishing. <br /> 3. Floors and Walls: Where walls or partitions that are removed extend one finished area into another, patch and <br /> repair floor and wall surfaces in the new space. Provide an even surface of uniform finish, color, texture, and <br /> appearance. Remove existing floor and wall coverings and replace with new materials, if necessary, to <br /> achieve uniform color and appearance. <br /> a. Where patching occurs in a painted surface, apply primer and intermediate paint coats over the patch and <br /> apply final paint coat over entire unbroken surface containing the patch. Provide additional coats until <br /> patch blends with adjacent surfaces. <br /> 4. Ceilings: Patch, repair, or re-hang existing ceilings as necessary to provide an even-plane surface of uniform <br /> appearance. <br /> 5. Exterior Building Enclosure: Patch components in a manner that restores enclosure to a weathertight <br /> condition. <br /> END OF SECTION 01 73 29 <br /> ©BOOMERANG DESIGN#1835 01 73 29-2 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 12/07/2018 <br />
