PART 3 - EXECUTION
3.1 GENERAL
A. 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.
3.2 CUTTING
A. 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
Chi Phi Fraternity August 4, 2014
Interior Finishes Restoration
INTERIOR FINISH CARPENTRY Bero Architecture PLLC 062023 - 4 14060.062023.21614
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.
3.3 REMOVALS
A. Photograph areas where removals will occur to show original configuration. Each item
scheduled for removal is to be identified in the photograph using non-bleeding permanent
marker on painter’s tape, or similar tape proven not to remove existing finish when removed,
with item numbered to show location in two planes. As each item is removed mark the back
side with the same identification as that on the front.
1. Store items in a safe location to prevent breakage, scratching, or theft. Stack neatly in
layers on untreated 4x4 blocking not more than 24” oc. Leave 2” between each item in a
layer. Provide cross blocking, aligned with base blocking, between layers to allow free
flow of air around all items. Cross blocking are to be straight, uniformly thick,
thoroughly dry and the same width as the stack. Do not stack more than head high.
2. Profiled or unevenly carved items are to supported as specified above but do not stack.
Store in a single layer only.
3. Items of similar lengths are to be stacked together. For each layer, stack longer pieces at
the edges for greater stability. Do not allow ends to overhang the stack without support.
Put thicker items at the bottom of the stack.
4. Provide environmental conditions similar to those in the areas from which items are
removed. Do not allow excessive heat, cold, dampness, or dryness. Provide sufficient
blocking that no item is allowed to deformation from lack of support. Reinstall all items
in the exact location from which they were removed.
3.4 PATCHING
A. 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.
B. Inspection: Where feasible, test and inspect patched areas after completion to demonstrate
integrity of installation.
C. 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.
3.5 PREPARATION FOR CLEANING
A. Removing original finish or patina is not desirable. Cleaning is intended to remove loose dirt,
dust, and superficial buildup. Some evidence of age of the items being cleaned should remain
after cleaning. In all cases the most gentle cleaning methods will be used. Methods below are
listed gentlest to most aggressive. Do not proceed to next method without written authorization
from Owner.
Chi Phi Fraternity August 4, 2014
Interior Finishes Restoration
INTERIOR FINISH CARPENTRY Bero Architecture PLLC 062023 - 5 14060.062023.21614
B. Test items to be cleaned prior to cleaning to determine if finish is shellac: Dampen a clean a
cotton cloth with denatured alcohol. Rub surface to be cleaned in a concealed location. If the
finish becomes “gummy” the finish is shellac. Notify Owner for instructions for proceeding
with cleaning.
3.6 CLEANING METHODS
A. First method:
1. Remove loose surface soil or dust using a clean, soft cotton cloth or vacuum with a clean
soft brush attachment. Wipe surface with cotton cloth dampened with mineral spirits.
Soft bristle brush dipped in mineral spirits shall be used to clean hard to reach areas not
accessible with cotton cloth such as carvings and intricate parts of the items being
cleaned.
2. Wipe surface with clean cloth again and let dry for several hours. Where second cleaning
is required, wipe lightly with clean cotton cloth dampened in cleaning detergent. Wipe
with cloth slightly dampened in clear water. Wipe dry with clean cloth.
B. Second method:
1. Remove dust, dirt, oil, grease, and sticky residue with job-mixed detergent solution; rinse
thoroughly and allow to dry. Protect adjacent surfaces from cleaning process by masking
surfaces. Detergent can damage metal, painted surfaces, stained wood, and glass.
C. Third method:
1. For heavy-duty cleaning where job-mixed detergent solution does not adequately remove
residue, mix 1 cup tetrasodium polyphosphate with 3 quarts water. Apply in a limited
amount to substrate and protect adjacent construction.
D. Other.
1. Mineral spirits only may be used if other methods are unsuccessful. Follow
manufacturer’s written instruction regarding ventilation or breathing device requirements
when using mineral spirits.
2. Remove hardware, covers, plates, and similar items already in place that are removable
and are not to be painted. If removal is impractical or impossible because of size or
weight of item, provide surface-applied protection.
a. After completing reinstallation, use workers skilled in the trades involved to
reinstall items that were removed. Remove surface-applied protection if any.
3.7 PREPARATION
A. Before installing interior finish carpentry, condition materials to average prevailing humidity in
installation areas for a minimum of 24 hours unless longer conditioning is recommended by

3.10 STANDING AND RUNNING TRIM INSTALLATION
A. Install with minimum number of joints practical, using full-length pieces from maximum
lengths of lumber available. Miter at returns, miter at outside corners, and cope at inside corners
to produce tight-fitting joints with full-surface contact throughout length of joint. Use scarf
joints for end-to-end joints.
