6. Where cutting and patching involves addition of reinforcement to structural 33
elements, submit details and engineering calculations to show how 34
reinforcement is integrated with the original structure. 35
7. Approval by the Architect to proceed with cutting and patching dos not waive the 36

the work found to be unsatisfactory. 38
39
1.03 QUALITY ASSURANCE 40
41
A. Requirements for Structural Work: Do not cut and patch structural elements in a 42
manner that would reduce their load-carrying capacity or load-deflection ratio. 43

or safety. 7
1. Obtain approval of the cutting and patching proposal before cutting and patching 8
the following operating elements or safety related systems: 9

building's aesthetic qualities, or result in visual evidence of cutting and patching. 25
Remove and replace work cut and patched in a visually unsatisfactory manner. 26
1. 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

2.01 MATERIALS 43
44
A. Use materials that are identical to existing materials. If identical materials are not 45
available or cannot be used where exposed surfaces are involved, use materials that 46
match existing adjacent surfaces to the fullest extent possible with regard to visual 47
effect. Use materials whose installed performance will equal or surpass that of 48
existing materials. 49

PART 3 - EXECUTION 1

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

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

A. The enclosed details for this project are intended primarily to present the proper 14
installation of the membranes used for waterproofing at flashings, perimeter closures, 15
roof projections, etc. Specific underlying construction configurations, such as walls, 16
nailers, wood backing, structural steel, etc., which may currently be in place may or may 17
not be accurately depicted on the attached details. Unless specifically called out in the 18
accompanying written specifications, or where a detail is noted "AS DRAWN", and/or 19
proper roofing and construction practices are not being followed, underlying 20
construction configurations are to remain unchanged from those in place on the building 21
