For exposed surfaces, use materials that visually match existing adjacent surfaces to the fullest extent possible if identical materials are unavailable or cannot be used. Use materials whose installed performance will equal or surpass that of existing materials. PART 3 - E X E C U T I O N 3.1 INSPECTION A. Examine surfaces to be cut and patched and conditions under which cutting and patching is to be performed before cutting. If unsafe or unsatisfactory conditions are encountered, take corrective action before proceeding. 1. Before proceeding, meet at the Project Site with parties involved in cutting and patching, including mechanical and electrical trades. Review areas of HZ Project R Gerald Thomas Hall Cutting and Patching Fume Hood Replacement

10 3.2 PREPARATION potential interference and conflict. Coordinate procedures and resolve potential conflicts before proceeding. A. Temporary Support. Provide temporary support of work to be cut. B. Protection. Protect existing construction during cutting and patching to prevent damage.

Avoid cutting existing pipe, conduit, or ductwork serving the building but scheduled to be removed or relocated until provisions have been made to bypass them. 3.3 PERFORMANCE A. General. Employ skilled workmen to perform cutting and patching. Proceed with cutting and patching at the earliest feasible time and complete without delay. 1. Cut existing construction to provide for installation of other components or performance of other construction activities and the subsequent fitting and patching required to restore surfaces to their original condition. B. Cutting. Cut existing construction using methods least likely to damage elements retained or adjoining construction. Where possible, review proposed procedures with the original Installer; comply with the original Installer's recommendations. 1. In general, where cutting, use hand or small power tools designed for sawing or 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. To avoid marring existing finished surfaces, cut or drill from the exposed or finished side into concealed surfaces. 3. Cut through concrete and masonry using a cutting machine, such as a Carborundum saw or a diamond-core drill. 4. Comply with requirements of applicable Division 2 Sections where cutting and patching requires excavating and backfilling. HZ Project R Gerald Thomas Hall Cutting and Patching Fume Hood Replacement

11 5. Where services are required to be removed, relocated, or abandoned, bypass utility services, such as pipe or conduit, before cutting. Cut-off pipe or conduit in walls or partitions to be removed. Cap, valve, or plug and seal the remaining portion of pipe or conduit to prevent entrance of moisture or other foreign matter after by-passing and cutting. 6. At roof; a. Ensure cutting operations do not adversely affect existing roof system warranty. b. Proceed with cutting into existing roof only when existing and forecasted weather conditions permit roofing system to be penetrated and patched according to manufacturer's written instructions and warranty requirements. C. Patching. Patch with durable seams that are as invisible as possible. Comply with specified tolerances. 1. Where feasible, inspect and test patched areas to demonstrate integrity of the installation. 2. 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. a. Where patching occurs in a smooth painted surface, extend final paint coat over entire unbroken surface containing the patch after the area has received primer and second coat. 3. At roof; ensure patching materials are fully compatible with existing roof system to provide a continuous, water-tight roof. 4. Patch, repair, or re-hang existing ceilings as necessary to provide an evenplane surface of uniform appearance. D. Plaster Installation. Comply with manufacturer's instructions and install thickness and coats as indicated. 1. Unless otherwise indicated, provide 3-coat work. 2. Finish gypsum plaster to match existing adjacent surfaces. Sand lightly to remove trowel marks and arises. 3. Cut, patch, point-up, and repair plaster to accommodate other construction. HZ Project R Gerald Thomas Hall Cutting and Patching Fume Hood Replacement

12 3.4 CLEANING A. Clean all areas and spaces affected by cutting and patching operations even if they are not within or adjacent to areas where cutting or patching was performed.
