Cutting and Patching Proposal: Where approval of procedures for cutting and 19 patching is required before proceeding, submit a proposal describing procedures well 20 in advance of the time cutting and patching will be performed and request approval to 21 proceed. Include the following information, as applicable, in the proposal: 22 1. Describe the extent of cutting and patching required and how is to be performed, 23 and indicate why it cannot be avoided. 24 2.

If possible, retain the original installer or fabricator to cut and patch the following 27 categories of exposed work, or if it is not possible to engage the original installer 28 or fabricator, engage another recognized experienced and specialized firm: 29 a) Matched-veneer woodwork 30 b) Performed metal panels 31 c) Window wall system 32 d) Acoustical ceilings 33 e) Finished wood flooring 34 f) Carpeting 35 g) Aggregate wall coating 36 h) Wall covering 37 i) HVAC enclosures, cabinets or covers 38 39 40 PART 2 - PRODUCTS 41 42 2.01 MATERIALS 43 44 A. Use materials that are identical to existing materials.

Use materials whose installed performance will equal or surpass that of 48 existing materials. 49 50 51 CITY OF DENTON PROJECT NO.19-1104-30 DENIA RECREATION CENTER, DENTON, TX CUTTING AND PATCHING 01 73 29 - 3 PART 3 - EXECUTION 1 2 3.01 INSPECTION 3 4 A. Before cutting existing surfaces, examine surfaces to be cut and patched and 5 conditions under which cutting and patching is to be performed. Take corrective 6 action before proceeding if unsafe or unsatisfactory conditions are encountered. 7 1. Before proceeding, meet at the site with parties involved in cutting and patching, 8 including mechanical and electrical trades. Review areas of potential 9 interference and conflict. Coordinate procedures and resolve potential conflicts 10 before proceeding. 11 12 3.02 PREPARATION 13 14 A. Temporary Support: Provide temporary support of work to be cut. 15 16 B. Protection: Protect existing construction during cutting and patching to prevent 17 damage. Provide protection from adverse weather conditions for portions of the 18 Project that might be exposed during cutting and patching operations. 19 1. Avoid interference with use of adjoining areas or interruption of free passage to 20 adjoining areas. 21 2. Take all precautions necessary to avoid cutting existing pipe, conduit or 22 ductwork serving the building, but scheduled to be removed or relocated until 23 provisions have been made to bypass them. 24 25 3.03 PERFORMANCE 26 27 A. General: Employ skilled workmen to perform cutting and patching. Proceed with 28 cutting and patching at the earliest feasible time and complete without delay. 29 1. Cut existing construction to provide for installation of other components or 30 performance of other construction activities and the subsequent fitting and 31 patching required to restore surfaces to their original condition. 32 33 B. Cutting: Cut existing construction using methods least likely to damage elements to 34 be retained or adjoining construction. Where possible, review proposed procedures 35 with the original installer, and comply with the original installer's recommendations. 36 1. In general, where cutting is required, use one hand or small power tools 37 designed for sawing or grinding, not hammering and chopping. Cut holes and 38 slots neatly to size required with minimum disturbance of adjacent surfaces. 39 Temporarily cover openings when not in use. 40 2. To avoid marring existing finished surfaces, cut or drill from the exposed or 41 finished side into concealed surfaces. 42 3. Cut through concrete and masonry using a cutting machine such as a 43 carborundum saw or diamond core drill. 44 4. Comply with requirements of applicable sections of Division 2 where cutting and 45 patching requires excavating and backfilling. 46 5. Bypass utility services such as pipe or conduit, before cutting, where services 47 are shown or required to be removed, relocated or abandoned. Cut-off pipe or 48 conduit in walls or partitions to be removed. Cap, valve or plug and seal the 49 remaining portion of pipe or conduit to prevent entrance of moisture or other 50 foreign matter after bypassing and cutting. 51 CITY OF DENTON PROJECT NO.19-1104-30 DENIA RECREATION CENTER, DENTON, TX CUTTING AND PATCHING 01 73 29 - 4 1 C. Patching: Patch with durable seams that are as invisible as possible. Comply with 2 specified tolerances. 3 1. Where feasible, inspect and test patched areas to demonstrate integrity of the 4 installation. 5 2. Restore exposed finishes of patched areas and extend finish restoration into 6 retained adjoining construction in a manner that will eliminate evidence of 7 patching and refinishing. 8 3. Where removal of walls or partitions extends one finished area into another, 9 patch and repair floor and wall surfaces in the new space to provide an even 10 surface of uniform color and appearance. Remove existing floor and wall 11 coverings and replace with new materials, if necessary, to achieve uniform color 12 and appearance. 13 4. Where patching occurs in a smooth painted surface, extend final paint coat over 14 entire unbroken area containing the patch after the patched area has received 15 primer and second coat. 16 5. Patch, repair or rehang existing ceilings as necessary to provide an even plane 17 surface of uniform appearance. 18 19 3.04 CLEANING 20 21 A. Thoroughly clean areas and spaces where cutting and patching is performed or used 22 as access. Remove completely paint, mortar, oils, putty and items of similar nature. 23 Thoroughly clean piping, conduit and similar features before painting or other finishing 24 is applied. Restore damaged pipe covering to its original condition. 25 26 27 28 END OF SECTION 01 73 2929 CITY OF DENTON PROJECT NO.19-1104-30 DENIA RECREATION CENTER, DENTON, TX MISCELLANEOUS ROUGH CARPENTRY 06 10 53 - 1 SECTION 06 10 53 1 MISCELLANEOUS ROUGH CARPENTRY 2 3 4 PART 1 – GENERAL 5 6 1.01 DESCRIPTION 7 8 A.
