Products: List products to be used and firms or entities that will perform the Work. <br />4. Dates: Indicate when cutting and patching will be performed. <br />5. Utility Services and Mechanical/Electrical Systems: List services/systems that cutting and <br />patching procedures will disturb or affect. List services/systems that will be relocated and those <br />that will be temporarily out of service. Indicate how long services/systems will be disrupted. <br />6. Structural Elements: Where cutting and patching involve adding reinforcement to structural <br />elements, submit details and engineering calculations showing integration of reinforcement with <br />original structure. <br />7. Architect's Approval: Obtain approval of cutting and patching proposal before cutting and <br />patching. Approval does not waive right to later require removal and replacement of <br />unsatisfactory work. <br />1.6 QUALITY ASSURANCE <br />A. Structural Elements: Do not cut and patch structural elements in a manner that could change their load- <br />carrying capacity or load-deflection ratio. <br />B. Operational Elements: Do not cut and patch operating elements and related components in a manner that <br />results in reducing their capacity to perform as intended or that results in increased maintenance or <br />decreased operational life or safety. Operational elements include but are not limited to: <br />1. Primary operational systems and equipment. <br />2. Air or smoke barriers. <br />3. Fire-suppression systems. <br />4. Mechanical systems piping and ducts. <br />5. Control systems. <br />6. Communication systems. <br />7. Conveying systems. <br />8. Electrical wiring systems. <br />9. Operating systems of special construction in Division 13 Sections. <br />C. Miscellaneous Elements: Do not cut and patch miscellaneous elements or related components in a <br />manner that could change their load-carrying capacity, that results in reducing their capacity to perform <br />as intended, or that results in increased maintenance or decreased operational life or <br />safety. Miscellaneous elements include but are not limited to the following: <br />1. Water, moisture, or vapor barriers. <br />2. Membranes and flashings. <br />3. Exterior curtain-wall construction. <br />4. Equipment supports. <br />5. Piping, ductwork, vessels, and equipment. <br />6. Noise- and vibration-control elements and systems. <br />D. Visual Requirements: Do not cut and patch construction in a manner that results in visual evidence of <br />cutting and patching. Do not cut and patch construction exposed on the exterior or in occupied spaces in <br />a manner that would, in Architect's opinion, reduce the building's aesthetic qualities. Remove and replace <br />construction that has been cut and patched in a visually unsatisfactory manner. <br />E. Cutting and Patching Conference: Before proceeding, meet at Project site with parties involved in cutting <br />and patching, including mechanical and electrical trades. Review areas of potential interference and <br />conflict. Coordinate procedures and resolve potential conflicts before proceeding. <br />DocuSign Envelope ID: ECCAC5A0-6CC8-4B37-8AD3-89D69F0AE1AE
