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

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
