SECTION 017329 -CUTTING AND PATCHING
PART 1 -GENERAL
1.1 RELATED DOCUMENTS
A.Drawings and general provisions of the Contract, including General and
Supplementary Conditions and other Division 01 Specification Sections, apply
to this Section.
1.2 SUMMARY
A.This Section includes procedural requirements for cutting and patching.
1.3 DEFINITIONS
A.Cutting: Removal of in-place construction necessary to permit installation or
performance of other Work.
B.Patching: Fitting and repair work required to restore surfaces to original
conditions after installation of other Work.
1.4 SUBMITTALS
1.5 QUALITY ASSURANCE
A.Structural Elements: Do not cut and patch structural elements in a manner
that could change their load-carrying capacity or load-deflection ratio.
B.Operational Elements: Do not cut and patch operating elements and related
components in a manner that results in reducing their capacity to perform as
intended or that results in increased maintenance or decreased operational life
or safety.
1.Primary operational systems and equipment.
2.Electrical wiring systems.

C.Miscellaneous Elements: Do not cut and patch miscellaneous elements or
related components in a manner that could change their load-carrying
capacity, that results in reducing their capacity to perform as intended, or that
results in increased maintenance or decreased operational life or safety.
1.Piping, ductwork, vessels, and equipment.
D.Visual Requirements: Do not cut and patch construction in a manner that
results in visual evidence of cutting and patching. Do not cut and patch
construction exposed on the exterior or in occupied spaces in a manner that
would, in Architect's opinion, reduce the building's aesthetic qualities. Remove
and replace construction that has been cut and patched in a visually
unsatisfactory manner.
PART 2 -PRODUCTS
2.1 MATERIALS
A.General: Comply with requirements specified in other Sections.
B.In-Place Materials: Use materials identical to in-place materials. For exposed
surfaces, use materials that visually match in-place adjacent surfaces to the
fullest extent possible.
1.If identical materials are unavailable or cannot be used, use materials
that, when installed, will match the visual and functional performance of
in-place materials.
PART 3 -EXECUTION
3.1 EXAMINATION
A.Examine surfaces to be cut and patched and conditions under which cutting
and patching are to be performed.
1.Compatibility: Before patching, verify compatibility with and suitability of
substrates, including compatibility with in-place finishes or primers.

2.Proceed with installation only after unsafe or unsatisfactory conditions
have been corrected.
3.2 PREPARATION
A.Temporary Support: Provide temporary support of Work to be cut.
B.Protection: Protect in-place construction during cutting and patching to
prevent damage. Provide protection from adverse weather conditions for
portions of Project that might be exposed during cutting and patching
operations.
C.Adjoining Areas: Avoid interference with use of adjoining areas or interruption
of free passage to adjoining areas.
3.3 PERFORMANCE
A.General: Employ skilled workers to perform cutting and patching. Proceed
with cutting and patching at the earliest feasible time, and complete without
delay.
1.Cut in-place construction to provide for installation of other components
or performance of other construction, and subsequently patch as
required to restore surfaces to their original condition.
B.Cutting: Cut in-place construction by sawing, drilling, breaking, chipping,
grinding, and similar operations, including excavation, using methods least
likely to damage elements retained or adjoining construction. If possible,
review proposed procedures with original Installer; comply with original
Installer's written recommendations.
1.In general, use hand or small power tools designed for sawing and
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.Finished Surfaces: Cut or drill from the exposed or finished side into
concealed surfaces.

3.Mechanical and Electrical Services: Cut off pipe or conduit in walls or
partitions to be removed. Cap, valve, or plug and seal remaining portion
of pipe or conduit to prevent entrance of moisture or other foreign matter
after cutting.
4.Proceed with patching after construction operations requiring cutting are
complete.
C.Patching: Patch construction by filling, repairing, refinishing, closing up, and
similar operations following performance of other Work. Patch with durable
seams that are as invisible as possible. Provide materials and comply with
installation requirements specified in other Sections.
1.Inspection: Where feasible, test and inspect patched areas after
completion to demonstrate integrity of installation.
2.Exposed Finishes: 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.Clean piping, conduit, and similar features before applying paint or
other finishing materials.
b.Restore damaged pipe covering to its original condition.
3.Floors and Walls: Where walls or partitions that are removed extend one
finished area into another, patch and repair floor and wall surfaces in the
new space. Provide an even surface of uniform finish, color, texture, and
appearance. Remove in-place floor and wall coverings and replace with
new materials, if necessary, to achieve uniform color and appearance.
a.Where patching occurs in a painted surface, apply primer and
intermediate paint coats over the patch and apply final paint coat
over entire unbroken surface containing the patch. Provide
additional coats until patch blends with adjacent surfaces.
4.Ceilings: Patch, repair, or rehang in-place ceilings as necessary to
provide an even-plane surface of uniform appearance.
5.Exterior Building Enclosure: Patch components in a manner that restores
enclosure to a weathertight condition.
