1.3
SAMPLE PANEL
**************************************************************************
NOTE: On projects where construction of a sample
panel or panels would be disproportionately
expensive or is considered not necessary to control
quality, this paragraph will be deleted. On complex
projects, modify this paragraph to require
additional sample panels for different types and
colors of masonry when more than one type is used in
sufficient quantity or in locations which warrant
samples.
**************************************************************************
After the material samples are approved and prior to starting masonry work,
a sample masonry panel shall be built on the project site where directed.
The sample panel shall be not less than 1.8 m 6 feet long by 1.2 m 4 feet
high. The panel shall be of typical wall thickness for the construction
represented. The panel shall show color range, texture, bond pattern,
expansion joints, and cleaning of the masonry as required in the work. The
panel shall also show cold-formed steel framing, insulation, gypsum
wallboard, gypsum sheathing, moisture barrier, vapor barrier, veneer
anchors, joint reinforcement, steel shelf angles, flashing and weep holes.
The approved sample panel shall be used as a standard of workmanship
required in the actual installation. The sample panel shall be protected
from weather and construction operations and shall not be removed until the
masonry veneer/steel stud wall work has been completed and accepted.
1.4
DELIVERY, HANDLING AND STORAGE
Materials shall be delivered and handled avoiding chipping, breakage,
bending or other damage, and contact with soil or other contaminating
materials. The masonry products shall be stored off the ground and
protected from inclement weather. Cementitious materials shall be
delivered in unopened containers plainly marked and labeled with
manufacturer's names and brands. Cementitious materials shall be stored in
dry, weather-tight enclosures or covers. Sand and other aggregates shall
be stored preventing contamination or segregation and under a weather-tight
covering permitting good air circulation. Finish of the framing members
shall be maintained at all times, using an approved high zinc dust content
galvanizing repair paint whenever necessary to prevent the formation of
rust. Insulation, moisture barrier, and gypsum sheathing shall be stored
in dry, well ventilated, weather-tight areas protected from sunlight and
excessive heat. Air infiltration type vapor barrier shall be stored in
accordance with the manufacturer's recommendations.
1.5
EFFLORESCENCE TESTS
**************************************************************************
NOTE: In areas where efflorescence is not
considered to be a problem, this paragraph will be
deleted. Efflorescence is usually caused by
allowing water to enter at the tops of walls and the
veneer offsets. Testing for efflorescence is
usually not required.
**************************************************************************
Efflorescence tests shall be performed by an approved commercial testing
laboratory. Sampling for the tests shall be the responsibility of the
