NOTE: Review Submittal Description (SD) definitions in Section 01 33 00 SUBMITTAL
PROCEDURES and edit the following list to reflect only the submittals required
for the project. Submittals should be kept to the minimum required for adequate
quality control.
A “G” following a submittal item indicates that the submittal requires Government
approval. Some submittals are already marked with a “G”. Only delete an existing
“G” if the submittal item is not complex and can be reviewed through the Contractor’s
Quality Control system. Only add a “G” if the submittal is sufficiently important
or complex in context of the project.
For submittals requiring Government approval on Army projects, a code of up
to three characters within the submittal tags may be used following the "G"
designation to indicate the approving authority. Codes for Army projects using
the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO"
for District Office (Engineering Division or other organization in the District
Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project
Office. Codes following the "G" typically are not used for Navy, Air Force,
and NASA projects.
Choose the first bracketed item for Navy, Air Force and NASA projects, or choose
the second bracketed item for Army projects.
Government approval is required for submittals with a "G" designation; submittals not having a "G" designation
are [for Contractor Quality Control approval.][for information only. When used, a designation following the
"G" designation identifies the office that will review the submittal for the Government.] Submit the following

NOTE: Coordinate editing of color reference sentence(s) with the Government.
Generally, Section 09 06 90 COLOR SCHEDULE or drawing is used when the project
is designed by an Architect or Interior designer. Select color from manufacturers
standard colors or identified as a manufacturers color in this specification
only when the project is very simple and has minimal finishes.
When the Government directs that color be located in the drawings add a note
that states: "Where color is shown as being specific to one manufacturer, an
equivalent color by another manufacturer may be submitted for approval. Manufacturers
and materials specified are not intended to limit the selection of equal colors
from other manufacturers. The word "color" as used herein includes surface
color and pattern."
Prior to specifying a custom color finish, research to determine if additional
cost and lead time is feasible. Note there is often a minimum order requirement;
this requirement will also affect future orders.
When a manufacturer's name, stock number, pattern, and color is used, be certain
that the product conforms to this specification, as edited.
Color must be [in accordance with Section 09 06 90 COLOR SCHEDULE.] [as indicated on the drawings.] [selected
from manufacturers standard colors.] [[______.] Color listed is not intended to limit the selection of equal
colors from other manufacturers.]

related and dimensional positions, and locations for roughing in plumbing, including sinks, faucets, strainers
and cocks.
3.1.1 Preliminary Installation and Adjustment
Install materials in accordance to manufacturer's recommendations. Lift and place to avoid breakage.
Position materials to verify that materials are correctly sized and prepared. Make necessary adjustments.
If jobsite cutting, grinding, or polishing is required, use water-cooled tools. Protect jobsite and
surfaces against dust and water. Perform work away from installation site if possible.
[Gypsum drywall back walls [which are not [fire][or][acoustically] rated] may be routed up to half the
thickness of the drywall to allow countertop to fit.]
[Shim countertop drainage [adjacent to sinks][and][where drainage is required], slightly to insure positive
drainage.]
3.1.2 Permanent Installation
After verifying fit, remove quartz surfacing from position, clean substrates of dust and contamination, and clean
quartz surfacing back side and joints with solvent.
Apply sufficient quantity of mounting adhesive in accordance with adhesive manufacturer's recommendations to
provide permanent, secure installation.
Spacing of mounting adhesive will not exceed:
Horizontal Surfaces: [_____] mm [_____] inch on center
Vertical Surfaces: [_____] mm [_____] inch on center; provide temporary shims until adhesive cures.
[Fasteners][Grout][Hardware]: [_____]
Install surfacing plumb, level, and square and flat to within 1.6 mm in 3 meters 1/6 inch in 10 feet.
3.1.3 Joints
Joints between adjacent pieces of quartz surfacing:
Joints must be flush, tight fitting, level, and neat.
Securely join with stone adhesive. Fill joints level with quartz surfacing.
Clamp or brace quartz surfacing in position until adhesive sets.
Joints [between backsplashes and countertops][and][around [tub][and][shower] enclosures]: Seal joints with silicone
sealer.
3.2 CLEANING
On completion of cabinet installation, touch up marred or abraded finished surfaces. Remove crating and packing
materials from premises. Wipe down surfaces to remove fingerprints and markings and leave in clean condition.
3.3 INSPECTION
Examine casework grounds and supports for adequate anchorage, foreign material, moisture, and unevenness that
could prevent quality casework installation.
Ensure that electrical and plumbing rough-ins for casework are complete. Do not proceed with installation until
defects are corrected.
