CUTTING AND PATCHING <br /> 010450 - 1 <br /> SECTION 010450- CUTTING AND PATCHING <br /> 1. GENERAL <br /> 1.1. Definition: "Cutting and patching" includes cutting into existing or new <br /> construction to provide for the installation or performance of other work and <br /> subsequent fitting and patching required to restore surfaces to their original <br /> condition. <br /> 1. Refer to other sections of these specifications for specific cutting and <br /> patching requirements and limitations applicable to individual units of <br /> work. <br /> 1.2. Structural Work: Do not cut-and-patch structural work in a manner resulting in a <br /> reduction of load-carrying capacity or load/deflection ratio. Submit proposal and <br /> request and obtain Architect's/Engineer's approval before proceeding with cut- <br /> and-patch of structural work. <br /> 1.3. Operational/Safety Limitations: Do not cut-and-patch operational elements and <br /> safety components in a manner resulting in decreased performance, shortened <br /> useful life, or increased maintenance. Submit proposals and requests and obtain <br /> Architect's approvals before proceeding with cut-and-patches. <br /> 1.4. Visual/Quality Limitations: Do not cut-and-patch work exposed to view <br /> (exterior and interior) in a manner resulting in noticeable reduction of aesthetic <br /> qualities and similar qualities, as judged by Architect. <br /> 1.5. Limitation on Approvals: Architect's approval to proceed with cutting and <br /> patching does not waive right to later require removal/replacement of work found <br /> to be cut-and-patched in an unsatisfactory manner, as judged by Architect. <br /> 2. MATERIALS <br /> 2.1. General: Use materials for cutting and patching that are identical to existing <br /> materials. If identical materials are not available, or cannot be used,use materials <br /> that match existing adjacent surfaces to the fullest extent possible with regard to <br /> visual effect. Use materials for cutting and patching that will result in equal-or- <br /> better performance characteristics. <br /> 3. EXECUTION <br /> 3.1. Inspection: Before cutting, examine surfaces to be cut and patched and <br /> conditions under which the work is to be performed. If unsafe or otherwise <br /> unsatisfactory conditions are encountered, take corrective action before <br /> proceeding with the work. <br /> 3.2. Temporary Support: To prevent failure provide temporary support of work to be <br /> cut. <br /> 02/19/13 <br />
