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.] The following shall

1.3 DELIVERY HANDLING AND STORAGE
Fenders shall be undamaged when delivered and shall be handled and stored so as to prevent damage, such as bending
or abrading end fittings, cutting of rubber, or damage to coating of hardware. Protect fenders from exposure
to damaging liquids, oils, greases and extended exposure to sunlight.

Fender shall be extruded and shall be continuous in the length indicated. The fenders shall have a truncated
"A" cross section shape and be attached to the structure at the base, the widest dimension, of the arch. The
connecting hardware shall be fully exposed. No encased hardware or molded fenders shall be allowed. The fender
and hardware shall be designed and factory tested to the loads per linear meter foot of fender specified in paragraph
entitled "PERFORMANCE," for angles of approach of 0 and 0.26 rad 0 and 15 degrees. Fender anchor bolts and method
of anchorage shall be of the size and spacing required by the manufacturer's design and testing; however, the
size and spacing of anchor bolts indicated on the drawings shall be construed to be the minimum required, unless
exceeded by the requirements of the fender manufacturer's design.

NOTE: Coordinate values with calculated design requirements.
When vertically compressed by a plate extending the full length and width of a 0.30 m one foot section of the
fender, the fender shll ab sorb [8950] [_____] joules [6,600] [_____] foot pounds of energy +10 percent when
[48] [_____] percent compressed (i.e., to a dimension of [52] [_____] percent of its original height) with a
corresponding load of not more than [85,402] [_____] N [19,200] [_____] pounds +10 percent.
2.4.1 FENDER COMPRESSION TEST
NOTE: Coordinate values with calculated design requirements.
Compress fender along its longitudinal axis between two parallel flat plate surfaces to a compressed dimension
of [48] [_____] percent of its original height. Record load and the corresponding deflection at 6 mm 1/4 inch
increments and plot as a graph of load versus deflection. The Load-Deflection curve shall then be integrated
to generate an Energy-Deflection curve for the fender. After compression of the fender to [48] [_____] percent
of its original height, the fender shall be rebound to 98 percent of its original height within [ten] [_____]
minutes after the load is removed.
2.4.2 ANGULAR FENDER COMPRESSION TEST
NOTE: Coordinate values with calculated design requirements.
Compress fender along its longitudinal axis between two flat plate surfaces, at an angle of [0.26] [_____] rad
[15] [_____] degrees to each other, to a compressed dimension of [48] [_____] percent of its original height.
Record load and the corresponding deflection at 6 mm 1/4 inch increments and plot as a graph of load versus deflection.
The Load-Deflection curve shall then be integrated to generate an Energy-Deflection curve for the fender. After
compression of the fender to [48] [_____] percent of its original height, the fender shall rebound to 98 percent
of its original height within [10] [_____] minutes after the load is removed.
