A floating dock system, heavy duty commercial type, designed and constructed with the following minimum requirements:

I. DESIGN STANDARDS

A. Drawing #

B. Floating dock system shall be designed as five foot long modularunits to facilitate interchange ability, flexibility of design, andmaintenance ability.

II. DESIGN LOAD CONDITIONS

A. Vertical Loads
1. Dead loads shall consist of the entire weight of the floating structure.
2. Flotation shall consist of the entire weight of the floating structure.
3. Freeboard
a.) Flotation shall provide freeboard of 17.00 inches under dead load of dock section. The dock is to float level under dead load conditions.
b.) Flotation shall provide 9.00 to 11.00 inches of freeboard under dead load plus a 20 psf uniform live load.
4. Deck surface shall withstand a punching shear stress of 150 psi.
5. The floating structures shall be designed to resist a 400 pound concentrated vertical load at any point on the deck surface without violation of the freeboard design requirement.

B. Horizontal Loads
A uniform horizontal wind loading from any direction shall be equal to 150 plf with a safety factor.

III. MATERIAL AND CONDITIONS MINIMUM REQUIREMENTS

A. Flotation
42 inch x 42 inch x 8 inch size, 400 pounds flotation
42 inch x 42 inch x 16 inch size, 900 pounds flotation
42 inch x 24 inch x 16 inch size, 600 pounds flotation
Flotation shall consist of 100% virgin grade material, ultra-violet stabilized, Linear low density pre-molded shell with compartmentalized air for secondary flotation. Flotation units shall be of one-piece rotational molded structure. Flotation units design to provide two 4-1/4 inch square grooves for utilities.
1. Linear low density polyethylene products shall meet the following standards:

Property	ASTM	Normal Values
Minimum Thickness (inches)		.125
Density, lb.cf	D1505	59
Tensile@Break.psi	D638	3,200
Low Temperature Brittleness
50% Failure @ 0 degrees C	D746	-90

2. Maintenance
Flotation units shall be low maintenance. Flotation units are considered as being part of the floating dock from the deck to bottom of the flotation units.
3. Flotation Integrity
Flotation units shall be designed to maintain buoyancy if structurally damaged. Connections of the flotation units shall be so designed that the dock acts as one unit. One unit does not deflect without adjacent units deflecting.
4. Fire ResistantFlotation units shall be of fire resistant construction.

B. Support Member - 3inch x 3 inch x 1/8 inch square tube
Structural frame shall be fabricated from galvanized steel tubing bolted to decking with 3/8 inch diameter AISI 18-8 steel, stainless bolts, washers and nuts.

C. Connections
1. Connections shall be designed so the units may be disconnected and moved. Material to be hot dip galvanized or stainless steel.
2. Individual structural units shall be bolted together with 3/8 inch to 1/2 inch diameter AISI 18-8 grade B5M stainless steel bolts.
3. Deck materials shall be fastened to float with 3/8 to 1/2 inch diameter AISI 18-8 grade stainless steel bolts, washers and nuts.

D. Decking
3-1/2 foot x 5 foot x 3-1/4 inch x .187 wall, 250# flotation
2 foot x 5 foot x 3-1/4 inch x .187 wall, 140# flotation
Decking material shall be 100% virgin grade, ultra-violet stabilized, medium density polyethylene. Deck shall be filled with 1.0 to 1.5 lb/cf polystyrene (EPS) foam. Deck shall be low maintenance with non-skid textured surface. Deck design must allow the total floating dock system to “flex” during inclement weather and heavy wave action to prevent dock failure. The deck material shall meet the following standards:

Property	ASTM	Nominal Values
Minimum Thickness (inches)		.187
Density, lb.cf	D1505	59
Tensile@Break.psi	D638	4,100
Torsional Stiffness, psi	D1043	115,000
Flexural Stiffness, psi	D747	98,000
Vicat Softening Pr., 0 degrees C	D1525	125
Low Temperature Brittleness
50% Failure @ 0 degrees C	D746	-76

E. Anchorage
Dock anchorage connections shall be designed to handle a predetermined size pole/piling or cable/anchor system.

F. CleatsTie down cleats shall be 10 inch size. They shall be fabricated from aluminum #356 or equal. All mounting hardware to be AISI 18-8 grade stainless steel.

G. Warranty
Floats - Eight Year Limited
Balance of Components - Five Year Limited
