similar operations, including excavation, using methods least likely to damage elements retained or adjoining construction. 1. In general, use hand or small power tools designed for sawing and grinding, not hammering and chopping. Cut holes and slots as small as possible, neatly to size required,and with minimum disturbance of adjacent surfaces. Temporarily cover openings when not in use. 2. Existing Finished Surfaces: Cut or drill from the exposed or finished side into concealed surfaces. 3. Concrete or Masonry: Cut using a cutting machine, such as an abrasive saw or a diamond-core drill. 4. Mechanical and Electrical Services: Cut off pipe or conduit in walls or partitions to be removed. Cap,valve, or plug and seal remaining portion of pipe or conduit to prevent entrance of moisture or other foreign matter after cutting. 5. Proceed with patching after construction operations requiring cutting are com- plete. C. Patching: Patch construction by filling,repairing,refinishing, closing up, and similar op- erations following performance of other Work. Patch with durable seams that are as in- visible as possible. Provide materials and comply with installation requirements speci- fied in other Sections of these Specifications. 1. Inspection: Where feasible, test and inspect patched areas after completion to demonstrate integrity of installation. 2. Exposed Finishes: Restore exposed finishes of patched areas and extend finish restoration into retained adjoining construction in a manner that will eliminate evidence of patching and refinishing. 3. Floors and Walls: Where walls or partitions that are removed extend from one finished area into another, patch and repair floor and wall surfaces in the new space. Provide an even surface of uniform finish, color, texture, and appearance. Remove existing floor and wall coverings and replace with new materials, if nec- essary,to achieve uniform color and appearance. a. Where patching occurs in a painted surface, apply primer and intermedi- ate paint coats over the patch and apply final paint coat over entire un- broken surface containing the patch. Provide additional coats until patch blends with adjacent surfaces. 4. Exterior Building Enclosure: Patch components in a manner that restores enclo- sure to a weather tight condition. 5. Ceilings: Patch, repair, or re-hang existing ceilings as necessary to provide an even-plane surface of uniform appearance. D. Cleaning: Clean areas and spaces where cutting and patching are performed. Completely remove paint,mortar,oils,putty and similar materials.
