Salient Characteristics This requirement is for the delivery of two (2) boat docks measuring 40 & 60 feet long.

1. Two floating modular docks:

a. Both docks shall be 8 feet wide.

b. One dock shall be 40 feet long and the second dock shall be 60 feet long.

c. Docks shall easily be removed using a ½ ton pickup with a standard ball hitch or a utility tractor. Contractor shall provide two (2) hitches with supplied docks.

d. Shall be self-anchoring, self-aligning when needed to be moved, no fixed anchors to pull, unhooking of cables, or removing driven posts.

e. Docks shall be capable of withstanding winds of at least 50 miles per hour from any direction and accompanying wave action with minimal deflection of dock both horizontally and vertically. A flow-through design shall be used to reduce wave impact and wind resistance.

f. Dock carrier frame and rollers shall be capable of moving over uneven and rocky shores and reservoir bottom and anchor the dock without creating any side slope on the floating units.

g. Dock carrier frame shall be capable of supporting the entire floating unit for winter removal and storage on-site.

h. Approach ramp:

i. Shall be continuous across the entire width of the dock, capable of being removed easily, and hinged to fold back for moving dock.

ii. Shall be level side to side and with water fluctuations capable of self-maintaining on a boat ramp slop of 1:12 or less to accommodate handicap use.

iii. Hinges shall intersect the top of the dock decking and produce a maximum ½-inch gap between ramp and dock deck.

i. Specifications:

i. The dead load shall be the entire weight of the floating units, and all equipment called for in the plans and specifications.

ii. Live load shall be the structural load for dock and ramp, and shall be 50 pounds per square foot, minimum.

iii. The deck surface shall be concentrated 300 pounds plus 33% impact total (400 pounds) applied over an area 12-foot x 12-foot. Uniform load of 50 pounds per square foot, flotation load of 30 pounds per square foot. Deflection of ramp and deck to be a maximum of 1/180.

iv. Frame shall provide sufficient built-in torsion resistance to positively prevent torsion, racking, and twisting by no more than 3-inches of variation in normal free board on the end of all deck units under normal load.

v. All floating units will have a structural metal frame to which the floatation, decking, hinges, and guided will be attached. Structural frames for floating units and carrier frame must be of all welded construction. Structural frames shall be a minimum of .120 cold formed square tube steel 1 ½-inch x 1 ½-inch minimum. Metal frames shall be powder coated a grey tone.

vi. The floatation units shall consist of a rectangular-shaped polyethylene case filled with formed-in-place polystyrene sealed to protect the foam form on all sides. Flotation shall be positively fastened to the frame and be capable of easy removal and replacement. These units shall be placed within the protected areas of the unit to prevent any impact from vessels or persons. Flotation freeboard under dead load shall be 12-inches minimum. Freeboard under dead load and a live load of 30 pounds per square foot shall not be less than 8-inches.

vii. The decking shall consist of 2-inch x 6-inch composite decking material placed perpendicular to the line of travel and fastened with at least two self-tapping screws at each structural cross support and countersunk, so the heads are slightly beneath the board surface. Gaps between boards shall not exceed ½-inch. Decking shall be grey in color.

viii. Connections between floating units shall be flexible and capable of transmitting all loads and forces imposed upon the units. Connections shall not protrude above the level of the deck nor produce more than a ½-inch gap between decking planks. Connections shall be a continuous type hinge and pin secured in place to prevent it from coming loose.

ix. Each floating unit shall have rub rails of 2-inch x 6-inch composite decking material on the frame even with the deck and bottom structural frame member. Round metal bull or bumper rail mounted 3-inches above the deck and shall run parallel along the entire outer edge of the deck.

x. The dock shall have a rolling anchor frame with a knee joint that allows for fluctuation of up to 18-feet as water level rises and lowers without movement of the dock.

xi. Each boat dock shall be equipped with a loading rail to allow users easier access into and out of their boats.

2. Warranties:

a. The docking system shall have a 2-year minimum warranty on all workmanship, structural components, decking and flotation.

b. The floats shall have a 100% non-prorated warranty for a minimum of 8 years against sinking, cracking, fragmenting, or loosening beads.

3. Service:

a. Delivery and set-up of both docks will be serviced at Clark Canyon Reservoir, Beaverhead and Lewis and Clark Campgrounds (see map provided).
