About this file
This is an Additional Specifications document for a state and local contract opportunity with the State of California for the Boat Boarding Float Replacement project at McArthur-Burney Falls Memorial State Park. The scope of work requires the contractor to construct and install a new 6-foot by 80-foot courtesy dock (480 square feet total) to existing piles and gangway, and remove and dispose of the existing dock. The dock frame and joists must be constructed from Marine-grade 6061-T6 aluminum with specific dimensional requirements: perimeter structural tubes measuring 4 inches wide by 11 inches tall by ½ inch thick, and interior joist tubes measuring 8 inches tall by 2 inches wide by 1/8 inch thick spaced no more than 19 inches apart. Hoop pile holders made from 1-inch square or round Marine-grade 6061-T6 aluminum stock will be welded and installed at 8, 38, and 61 feet. Heavy-duty flush-mounted piano hinges made from Marine-grade 6061-T6 aluminum with marine-grade hinge pins will connect dock sections and attach the dock to the existing gangway. Diagonal bracing creating a W pattern must be included in each section, with all welds requiring uniform bead width, consistent ripple patterns, and non-destructive testing.
The floating system shall consist of ACE Roto Mold floats or equivalent designed to support at least 40 pounds per square foot, totaling a capacity of 19,220 pounds for the entire dock. Floats must be one-piece foam-filled construction with heavy-duty mounting flanges and structural ribs, meeting ASTM D1998-06 impact test standards and Army Corps of Engineers Regulation 33CFR 327.30, installed with stainless steel hardware. Decking will be high-impact, weather-resistant grey vinyl with ultraviolet inhibitors (Brock Doc or equivalent) or aluminum, installed with a concealed clip system perpendicular to the frame. Marine-grade flexible PVC bumpers (RYKO or equivalent) in white will be installed along the top and bottom edges with stainless steel mounting hardware. The dock will include 16 eight-inch stainless steel pop-up cleats (Accon or equivalent) with four cleats per 20-foot dock section, centered and spaced no more than 12 feet apart, installed with removable stainless steel hardware.
