CUTTING AND PATCHING 01 73 29 - 1
SECTION 01 73 29
CUTTING AND PATCHING
PART 1 - GENERAL
1.01 SUMMARY
A. This section specifies administrative and procedural requirements for cutting and patching.
B. Refer to other sections for specific requirements and limitations applicable to cutting and
patching individual parts of the work.
1. Requirements of this section also apply to mechanical and electrical installations, as
well as work specified in other Divisions.
1.02 SUBMITTALS
A. Cutting and Patching Proposal: Where approval of procedures for cutting and patching is
required before proceeding, submit a proposal describing procedures well in advance of
the time cutting and patching will be performed and request approval to proceed. Include
the following information, as applicable, in the proposal:
1. Describe the extent of cutting and patching required and how is to be performed and
indicate why it cannot be avoided.
2. Describe anticipated results in terms of changes to existing construction. Include
changes to structural elements and operating components as well as changes in the
building's appearance and other significant visual elements.
3. List products to be used and firms or entities that will perform work.
4. Indicate dates when cutting and patching is to be performed.
5. List utilities that will be disturbed or affected, including those that will be relocated
and those that will be temporarily out-of-service. Indicate how long service will be
disrupted.
6. Where cutting and patching involves addition of reinforcement to structural elements,
submit details and engineering calculations to show how reinforcement is integrated
with the original structure.
7. Approval by the Architect to proceed with cutting and patching dos not waive the
Architect's right to later require complete removal and replacement of a part of the
work found to be unsatisfactory.
1.03 QUALITY ASSURANCE
A. Requirements for Structural Work: Do not cut and patch structural elements in a manner
that would reduce their load-carrying capacity or load-deflection ratio.
1. Obtain approval of the cutting and patching proposal before cutting and patching the
following structural elements:
a) Bearing and retaining walls
b) Structural concrete
c) Structural steel
d) Lintels
e) Structural decking
f) Miscellaneous structural metals
g) Equipment supports
CITY OF DENTON PROJECT NO. 20-1072-30
1117 RINEY ROAD, DENTON, TX
CUTTING AND PATCHING 01 73 29 - 2
h) Piping, ductwork, vessels and equipment
B. Operational and Safety Limitations: Do not cut and patch operating elements or safety
related components in a manner that would result in reducing their capacity to perform as
intended, or result in increased maintenance, or decreased operational life or safety.
1. Obtain approval of the cutting and patching proposal before cutting and patching the
following operating elements or safety related systems:
a) Shoring, bracing and sheeting
b) Primary operational systems and equipment
c) Air or smoke barriers
d) Water, moisture or vapor barriers
e) Membranes and flashings
f) Fire protection systems
g) Noise and vibration control elements and systems
h) Control systems
i) Communication systems
j) Conveying systems
k) Electrical wiring systems
C. Visual Requirements: Do not cut and patch construction exposed on the exterior or in
occupied spaces, in a manner that would, in the Architect's opinion, reduce the building's
aesthetic qualities, or result in visual evidence of cutting and patching. Remove and
replace work cut and patched in a visually unsatisfactory manner.
1. If possible, retain the original installer or fabricator to cut and patch the following
categories of exposed work, or if it is not possible to engage the original installer or
fabricator, engage another recognized experienced and specialized firm:
a) Matched-veneer woodwork
b) Performed metal panels
c) Window wall system
d) Acoustical ceilings
e) Finished wood flooring
f) Carpeting
g) Aggregate wall coating
h) Wall covering
i) HVAC enclosures, cabinets or covers
PART 2 - PRODUCTS
2.01 MATERIALS
A. Use materials that are identical to existing materials. If identical materials are not
available or cannot be used where exposed surfaces are involved, use materials that
match existing adjacent surfaces to the fullest extent possible with regard to visual effect.
Use materials whose installed performance will equal or surpass that of existing materials.
CITY OF DENTON PROJECT NO. 20-1072-30
1117 RINEY ROAD, DENTON, TX
CUTTING AND PATCHING 01 73 29 - 3
PART 3 - EXECUTION
3.01 INSPECTION
A. Before cutting existing surfaces, examine surfaces to be cut and patched and conditions
under which cutting, and patching is to be performed. Take corrective action before
proceeding if unsafe or unsatisfactory conditions are encountered.
1. Before proceeding, meet at the site with parties involved in cutting and patching,
including mechanical and electrical trades. Review areas of potential interference
and conflict. Coordinate procedures and resolve potential conflicts before
proceeding.
3.02 PREPARATION
A. Temporary Support: Provide temporary support of work to be cut.
B. Protection: Protect existing construction during cutting and patching to prevent damage.
Provide protection from adverse weather conditions for portions of the Project that might
be exposed during cutting and patching operations.
1. Avoid interference with use of adjoining areas or interruption of free passage to
adjoining areas.
2. Take all precautions necessary to 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.
3.03 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 to be
retained or adjoining construction. Where possible, review proposed procedures with the
original installer, and comply with the original installer's recommendations.
1. In general, where cutting is required, use one hand or small power tools designed for
sawing or grinding, not hammering and chopping. Cut holes and slots neatly to size
required 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 diamond core drill.
4. Comply with requirements of applicable sections of Division 2 where cutting and
patching requires excavating and backfilling.
5. Bypass utility services such as pipe or conduit, before cutting, where services are
shown or required to be removed, relocated or abandoned. 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
bypassing and cutting.
CITY OF DENTON PROJECT NO. 20-1072-30
1117 RINEY ROAD, DENTON, TX
CUTTING AND PATCHING 01 73 29 - 4
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.
3. Where removal of walls or partitions extends one finished area into another, patch
and repair floor and wall surfaces in the new space to provide an even surface of
uniform color and appearance. Remove existing floor and wall coverings and
replace with new materials, if necessary, to achieve uniform color and appearance.
4. Where patching occurs in a smooth painted surface, extend final paint coat over
entire unbroken area containing the patch after the patched area has received
primer and second coat.
5. Patch, repair or rehang existing ceilings as necessary to provide an even plane
surface of uniform appearance.
3.04 CLEANING
A. Thoroughly clean areas and spaces where cutting and patching is performed or used as
access. Remove completely paint, mortar, oils, putty and items of similar nature.
Thoroughly clean piping, conduit and similar features before painting or other finishing is
applied. Restore damaged pipe covering to its original condition.
