Orange County Solid Waste <br />Scalehouse Building 01 73 29 -3 CUTTING AND PATCHING <br />1.Cut existing construction to provide for installation of other components or <br />performance of other construction,and subsequently patch as required to restore <br />surfaces to their original condition. <br />B.Cutting: Cut existing construction by sawing,drilling,breaking,chipping,grinding,and <br />similar operations,including excavation,using methods least likely to damage elements <br />retained or adjoining construction. <br />1.In general,use hand or small power tools designed for sawing and grinding,not <br />hammering and chopping. Cut holes and slots as small as possible,neatly to <br />size required,and with minimum disturbance of adjacent surfaces. Temporarily <br />cover openings when not in use. <br />2.Existing Finished Surfaces: Cut or drill from the exposed or finished side into <br />concealed surfaces. <br />3.Concrete or Masonry: Cut using an abrasive saw or a diamond-core drill. <br />4.Mechanical and Electrical Services: Cut off pipe or conduit in walls or partitions <br />to be removed. Cap,valve,or plug and seal remaining portion of pipe or conduit <br />to prevent entrance of moisture or other foreign matter after cutting. <br />5.Proceed with patching after construction operations requiring cutting are <br />complete. <br />C.Patching: Patch construction by filling,repairing,refinishing,closing up,and similar <br />operations following performance of other Work. Patch with durable seams that are as <br />invisible as possible. Provide materials and comply with installation requirements <br />specified in other Sections of these Specifications. <br />1.Inspection: Where feasible,test and inspect patched areas after completion to <br />demonstrate 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 eliminate <br />evidence of patching and refinishing. <br />3.Floors and Walls:Where walls or partitions that are removed extend from one <br />finished area into another,patch and repair floor and wall surfaces.Provide an <br />even surface of uniform finish,color,texture,and appearance.Replace floor and <br />wall coverings,if necessary,to achieve uniform color and appearance. <br />a.Where patching occurs in a painted surface,apply primer and <br />intermediate paint coats over the patch and apply final paint coat over <br />unbroken surface containing the patch to the nearest joint or delineation <br />between materials.Provide additional coats until patch blends with <br />adjacent surfaces. <br />4.Exterior Building Enclosure: Patch components in a manner that restores <br />enclosure to a weather tight condition. <br />5.Ceilings:Patch,repair,or re-hang existing ceilings as necessary to provide an <br />even-plane surface of uniform appearance. <br />D.Renovation Project Procedures <br />Docusign Envelope ID: FA2D0569-6BCE-4E38-B3EE-9B3EFD09A753
