PROJECT SPECIFICATIONS

FABRICATE AND DELIVER 18 SLIP BOAT DOCK

WHISKEYTOWN NATIONAL RECREATION AREA

P16PS00184

A. SCOPE

Whiskeytown National Recreation Area (WNRA) is seeking to add 18 moorage boat slips to “A” Dock at Oak Bottom Marina. These docks are operated and used by the parks concessionaire (Forever Resorts) for rental boats and moorage slip customers for watercraft day use on Whiskeytown Lake. The slips are being added to fulfill visitor use trends and provide the concessionaire adequate space at the busiest marina with-in Whiskeytown National Recreation Area. The new dock and slips must match design details and engineering specifications of the 47 slip existing dock. The new dock and slips will be approximately 135 Ft. long and 58 Ft. wide. This includes winches, cleats, utility pedestals, concrete tiles, and 5th wheel dock attachment assembly. (See Tasks, Attachments, Specifications & Drawings)

This fabrication and delivery includes equal or like encased polyethylene pontoons. Docks must be designed to withstand wind loads producing a 20#/sf loading on the projected vertical surface of a boat 26 Ft. long and 2 Ft. 6 inches high (Department of Boating and Waterways marina berthing facility guidelines). Source selection must match existing design requirements and be the best value to the government. Contractor is to provide instructional specifications for existing dock modification for new dock attachment.
