1.3 SUBMITTALS
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.][information only. When used, a designation following the "G"

PART 3 EXECUTION
3.1 INSTALLATION
Joint locations and details, including materials and methods of installation of joint fillers and waterstops,
shall be as specified, as shown, and as directed. In no case shall any fixed metal be continuous through an
expansion or contraction joint.
3.1.1 Expansion Joints
Premolded filler strips shall have oiled wood strips secured to the top thereof and shall be accurately positioned
and secured against displacement to clean, smooth concrete surfaces. The wood strips shall be slightly tapered,
dressed and of the size required to install filler strips at the desired level below the finished concrete surface
and to form the groove for the joint sealant or seals to the size shown. Material used to secure premolded fillers
and wood strips to concrete shall not harm the concrete and shall be compatible with the joint sealant or seals.
The wood strips shall not be removed until after the concrete curing period. The groove shall be thoroughly
cleaned of all laitance, curing compound, foreign materials, protrusions of hardened concrete and any dust which
shall be blown out of the groove with oil-free compressed air.
3.1.1.1 Joints With Field-Molded Sealant
Joints shall not be sealed when the sealant, air or concrete temperature is less than 4 degrees C 40 degrees
F. Immediately prior to installation of field molded sealants, the joint shall be cleaned of all debris and
further cleaned using water, chemical solvents or other means as recommended by the sealant manufacturer. The
joints shall be dry prior to filling with sealant. Bond breaker and back-up material shall be installed where
required. Joints shall be primed and filled flush with joint sealant in accordance with the manufacturer's recommendations.
3.1.1.2 Joints With Preformed Compression Seals
The joint seals shall be installed with equipment which shall be capable of installing joint seals to the prescribed
depth without cutting, nicking, twisting, or otherwise distorting or damaging the seal and with no more than
five percent stretching of the seal. The sides of the joint and, if necessary, the sides of the compression
seal shall be covered with a coating of lubricant, and the seal shall be installed to the depth indicated with
joint installation equipment. Butt joints shall be coated with liberal applications of lubricant.
3.1.2 Contraction Joints
Joints requiring a bond breaker shall be coated with curing compound or with bituminous paint. Waterstops shall
be protected during application of bond breaking material to prevent them from being coated.
3.1.3 Waterstops
Waterstops shall be carefully and correctly positioned during installation to eliminate faulty installation that
may result in joint leakage. The bottom of each waterstop shall be embedded a minimum of 150 mm 6 inches in
firm rock or sealed to other cut-off systems. All waterstops shall be installed so as to form a continuous watertight
diaphragm in each joint. Adequate provision shall be made to support and protect the waterstops during the progress
of work. Any waterstop punctured or damaged shall be replaced or repaired at the Contractor's expense. The
concrete shall be thoroughly consolidated in the vicinity of the waterstop. Suitable guards shall be provided
to protect exposed projecting edges and ends of partially embedded waterstops from damage when concrete placement
has been discontinued.
3.1.3.1 Splices
Joints in waterstops shall be spliced together by qualified splicers using the approved splicing procedures to
form a continuous watertight diaphragm. Splices shall be as followed:
a. Non-Metallic Waterstops - All splices shall be made on a bench in a temporary shop provided at the
site of the installation or at the manufacturer's plant. A miter guide and portable power saw shall
be used to cut the ends to be joined to insure good alignment and contact between joined surfaces. Continuity
of the characteristic features of the cross section of the waterstop (ribs, tabular center axis, protrusions
and the like) shall be maintained across the splice.
b. Rubber Waterstops - Splices shall be vulcanized in accordance with the approved procedure.
c. Polyvinylchloride Waterstops - Splices shall be made by heat sealing the adjacent surfaces in accordance
with the approved procedure. A thermostatically controlled electrical heat source shall be used to make
all splices. The correct temperature at which splices should be made will differ with the material concerned
but the applied heat should be sufficient to melt but not char the plastic. Waterstops shall be reformed
at splices with a remolding iron with ribs or corrugations to match the pattern of the waterstop. The
spliced area, when cooled and bent by hand in as sharp an angle as possible, shall show no sign of separation.
d. Flexible Metal Waterstop - Splices in copper shall be lap joints made by the approved brazing procedure.
Splices in stainless steel shall be made by the approved welding procedure. Damaged waterstops shall
be repaired by removing damaged portions and patching. Patches shall overlap a minimum of 25 mm 1 inch
onto undamaged portion of the waterstop.
e. Flat Steel Waterstops - Splices shall be welded.
