TEMPORARY EMERGENCY LEVEE REMOVAL at JAMESTOWN, ND

1. Scope of Work The work covered under this contract shall consist of removal and material recycling or disposal of temporary emergency levee structures within the City of Jamestown, North Dakota. These levee structures were placed as temporary measures to protect the City under a Temporary Emergency Levee project in April 2009. Emergency levees to be removed are located on roads, rights of way, and private property. The contractor shall exercise caution and not cause further damage to property by utilizing the appropriate equipment to minimize such damage. The contractor will be responsible for correcting any areas damaged by operations under this contract.

The project consists of 1) removal of clay levees and plastic sheeting and stockpiling of levee material; 2) removal and recovery of Hesco bastions and removal and stockpiling of sand/gravel from Hesco contents; 3) removal of Rapid Deployment Flood Walls (RDFW) and removal and stockpiling of sand/gravel from RDFW contents; 4) removal and disposal of sandbags and plastic sheeting; 5) removal and stockpiling of rock rip rap; and 6) removal and disposal of construction and demolition waste. The work locations and estimated quantities are designated in Appendices A and B, respectively. The stockpile and disposal sites are located in Appendix C.

Appendix E. Rapid Deployment Flood Wall Removal Guidelines

The RDFW is composed of a series of interconnected cells.

· The outside white and red protective cells are 3.5" wide x 7" long x 8" inches high.

· Protective cell struts are 12" high

· Protective cell struts embed 4 inches into RDFW structure.

· The interior clear containment cells are 7" wide x 7" long x 8" inches high.

· Lock and Load connectors adjoin 4 ft long individual RDFW Base Units

Scope of Work Remove sand from connected RDFW base units, disconnect, collapse and clean base units. Repackage individual RDFW base units in RDFW containers. Repackaged RDFW base units must be in sufficient condition to be re-used.

*Note. RDFW removal can be done by hand. Direct contact with loader or forks will damage RDFW base units. High plasticity content in infill will solidify soil and make the removal process difficult and increase labor and removal cost.

Any other means to extract sand and protect RDFW Base Units such as vacuum equipment or other attachment configurations can be used. Attachments can be modified to suit conditions. Contractors are encouraged to fabricate and use more than one "Grappler Type Attachment" in the removal process. All extracting methods are the responsibility of the contractor.

The "RDFW Grappler Attachment" Removal Device is provided at no cost to the government. The attachment was created as a result of testing other methods. There is no obligation or requirement to use it. In previous installations, "Grappler Attachments" have been found to:

· Reduce damage to plastic;

· Reduce labor;

· Expedite removal sequence;

· Enhance recovery and re-use; and

· Be uncomplicated and easy to understand.

Labor

· 4 - remove sand from cells

· 2 - hook attachment to RDFW connected base units

· 4 - disconnect and collapse RDFW Units

· 4 - wash off / repair RDFW

· 2 - repackage RDFW into boxes for re-use

· 3 - skid loader operators

Equipment

· 2 to 3 skid loaders; 2 with buckets, 1 with forks.

Packaging Use RDFW containers found on site.

Suggested Instructions for Removal of RDFW with "Grappler Attachment" Grappler Attachment Instructions Sand Removal

· Remove sand to top of cells.

· Remove sand from protective cells and adjoining outside containment cells only. (Room is needed for wood blocks and "Grappler Pullers")

· Use a narrow spade or shovel capable of fitting into the cells to remove sand.

· Place wood 2" x 4" x 4" high blocks into protective cells that line up with "Grappler Pullers" on the attachment.

· Sand can be reused Grappler Attachment The Grappler attachment consists of a steel frame that hooks to a loader bucket and red "Grappler Pullers" that are chained to the attachment frame.

Ten (10) attached "Grappler Pullers" are located across from each other on the long side of attachment frame. (5 on each side)

· Hook "Grappler" attachment to loader bucket or crane.

· Lower "Grappler Pullers" over white 3.5" protective cells with 2 x 4 blocks inserted.

· “Grappler Pullers” will open as they are being lowered.

· Lift Grappler Attachment to secure "Pullers" to RDFW base units.

· Sand will escape to the bottom of the RDFW base units.

· Continue process; disconnect connections at various intervals or remove entire layer.

Loading and Hauling Sand

· Use loader bucket to back drag sand

· Haul sand to stockpile area

Re-Packaging

· Disconnect and collapse RDFW base units

· Wash sand off base units

· Place 100 collapsed base units in RDFW container

· Place individual RDFW base units with RDFW label to the back of the container, facing up.
