NOTE: Submittals must be limited to those necessary for adequate quality control.
The importance of an item in the project should be one of the primary factors
in determining if a submittal for the item should be required.
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 projects.
Submittal items not designated with a "G" are considered as being for information
only for Army projects and for Contractor Quality Control approval for Navy
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.] The following shall

PART 2 PRODUCTS
2.1 MATERIALS
NOTE: Wood is a renewable resource. Non-sustainable harvesting of wood can
produce soil erosion, pollutant runoff, increased levels of atmospheric carbon
dioxide, global warming, and habitat loss. Supplies of clear grades and large-dimension
timbers are limited. Specify lower grades and engineered wood products for
large-dimension timbers when appropriate.
2.1.1 Virgin Lumber
NOTE: Old growth timber comes from trees over 200 years old. In industry,
it is high quality lumber in "upper" or "architectural" grades. Lumber suppliers
should know which timber is old growth and which is not, but sources are not
always tracked.
Lumber fabricated from old growth timber is not permitted. Avoid companies who buy, sell, or use old growth
timber in their operations, when possible. [Lumber shall be FSC-certified.]
2.1.2 Engineered Wood Products
NOTE: Engineered wood products include plywood, OSB, composite wood panels,
fiberboard, particleboard, glue-laminated beams, structural composite lumber,
including laminated veneer lumber and parallel strand lumber, as well as I-joists
and metal plate connected wood trusses. The use of engineered wood products
can result in higher resource efficiencies than conventional lumber/timber construction.
Waste is minimized due to uniformity of product. Spans and/or spacing may be
increased for engineered joists over spans for same depth dimensional lumber.
However, adhesive binders used in engineered wood products are any of several
synthetic resins that pose varying degrees of human health risks. Engineered
wood products might be more difficult to recycle than standard, solid sawn lumber
due to the binders used in manufacturing. FSC-certified engineered wood products
are available by special order. Army projects shall specify certified wood
products only if pursuing this LEED (tm) credit. Designer must verify availability
and adequate competition before specifying product certified wood requirememts.
Use second option if Contractor is choosing wood prodcuts in accordance with
Section 01 33 29 LEED (tm) DOCUMENTATION.
NOTE: Choose one of the formaldehyde options. If products are known to contain
no added formaldehyde, testing for formaldehyde concentration is not required.
Formaldehyde can be harmful (as an allergen or carcinogen) at any level of concentration
above zero. At concentrations of about 40 ppb (cumulative for the indoor air
space), formaldehyde can cause eye, nose, and lung irritations.
NOTE: Using formaldehyde-free interior wood window products contributes to
the following LEED credit: EQ4. Exterior windows that are part of the building
weatherproofing system are not included in this LEED (tm) credit. Army projects
shall specify formaldehyde free requirements only for wood windows that are
not part of the building weatherproofing system and only if pursuing this LEED
credit.
[Products shall contain no added urea-formaldehyde. [Determine formaldehyde concentrations in air from engineered
wood products under test conditions of temperature and relative humidity in accordance with ASTM D 6007 or ASTM E 1333
. Products shall not be used if formaldehyde concentration is found to be greater than [0][_____]. ]Determine
Volatile Organic Compounds (VOCs), excluding formaldehyde, emitted from manufactured wood-based panels in accordance
with ASTM D 6330. Products shall not be used if VOC emissions exceed [_____].][Products shall be FSC-certified.][See
section 01 33 29 LEED (TM) DOCUMENTATION for cumulative total certified wood requirements. This item may be
available made form certified wood.]
2.1.3 [Metal] [Plastic] [_____]
NOTE: Use of materials with recycled content, calculated on the basis of post-industrial
and post-consumer percentage content, contributes to the following LEED credit:
MR4. Coordinate with Section 01 33 29 LEED(TM) DOCUMENTATION. Designer must
verify suitability, availability and adequate competition (including verification
of bracketed percentages included in this guide specification) before specifying
product recycled content requirements. Use second option if Contractor is choosing
recycled content products in accordance with Section 01 33 29 LEED (TM) DOCUMENTATION.
Army projects shall specify recycled content only if pursuing this LEED credit.
[Minimum [5][10][_____] percent post-consumer recycled content, or minimum [20][40][_____] percent post-industrial
recycled content.][See Section 01 33 29 LEED(tm) DOCUMENTATION for cumulative total recycled content requirements.
Metal and plastic materials may contain post-consumer or post-industrial recycled content.]
2.2 WOOD WINDOWS
NOTE: If window cleaning anchors are required, add:
"Window cleaning anchors to be stainless-steel, conforming to ASME A39.1. Reinforce
windows and frames for reception of anchors, and securely anchor window frames
to wall construction for window cleaning anchors."
NOTE: Where operating hardware is located 1980 mm 6 feet 6 inches or more above
floor, specify poles and pole-operated handles to operate windows.
NOTE: Show locations where storm units are to be installed. Windows for equipment
rooms, laundry rooms, and similar spaces should not be provided with storm units.
Storm windows are not required over double-glazed insulating type windows.
