B. Existing Warranties: Remove, replace, patch, and repair materials and surfaces cut or damaged during installation or cutting and patching operations, by methods and with materials so as not to void existing warranties.
C. 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. Concrete Masonry: Cut using a cutting machine, such as an abrasive saw or a diamond-core drill.

4. Cutting of Existing Roofing System due to the installation of HVAC equipment, must be performed in accordance with manufacturer’s instructions. Installation of the HVAC equipment must provide access for the repair of the roofing materials and flashing. Coordinate work with HVAC Contractor.

5. 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.

6. Proceed with patching after construction operations requiring cutting are complete.

D. 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.

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.

^{6. Elevated Concrete Slabs: Install a new concrete slab into an}

existing elevated concrete slab by continuously welding metal deck (with the same size, profile, and gauge as existing metal deck) to the existing metal deck with a minimum 3” overlap. New slab to be doweled into existing concrete slab with #4 dowels @ 24” O.C., all sides, with 6” minimum embedment and minimum (2) dowels per side. Epoxy the dowels into the existing slab.

3. Perform all roof top work in accordance with NRCA and manufacturer details and instructions.

^{4. Install flashing to conform to standards set forth in the SMACNA}

Architectural Sheet Metal Manual and NRCA Manual. All roof top work (Removal of existing roofing, installation of roofing materials, flashing, equipment, etc.) should be performed in the same day.

5. All work should be performed in a way that it doesn’t void the existing warranty. After work is completed the contractor must arrange for a final inspection with the manufacturer to verify work was done per their instruction.
F. Cleaning: Clean areas and spaces where cutting and patching are performed. Completely remove paint, mortar, oils, putty, and similar materials

3.4 CORRECTION OF THE WORK
