Appendix A – Wick Drain Requirements

1 Minimum Wick Drain Installation Equipment Capacity Requirements

· For existing equipment - provide current deliverable capacity in number of units.

· If planning to rent or subcontract for equipment - name the source so that industry capacity is not double counted in other submissions.

· For new equipment provide capacity of manufacturing and required lead times for delivery. If you are not the manufacturer, name the manufacturer so that industry capacity will not be double counted in other submissions.

2 Minimum Wick Drain Installation Equipment Requirements

The following are the minimum requirements for the wick drain installation equipment to be submitted:

· Capability to attach and be used on industry standard construction equipment, i.e. tracked or wheel dozers, excavators, etc. Alternatively, the capability to supply turn-key solutions which include the cab and installation attachments.

· Mandrel and mast configurations to install various lengths and widths of wick drains. Main wick drain size to be used will be 4-inch width. Depth could be as much as 50 feet deep plus.

· Automatic feeder from rolls on the equipment including capability for continuous feed from rolls.

· Mandrel capability to drive through various fabrics to be installed prior to wick drain installations, e.g. separator fabric, geogrids, reinforcement fabrics.

· Wick drains shall be assumed to be installed on a hard dry working surface of sand to be placed by others thence through marsh/deltaic deposits down to Pleistocene. The supplier should indicate capability of equipment supply which can operate in harsh wetland conditions as the project will be entirely within such an environment yet working from atop a sand platform.

· Supplier’s capability to repair on site or supply replacement equipment in a rapid manner without delay.

· Equipment’s’ installation speed measured in linear feet per minute to drive wick drains and speed to reposition for next installation of wick drains.
