a. Length: 1/10 inch per foot over the length of an individual boarding float section, not to exceed 1” in 10’.

b. Width: 1/8 inch per foot over the length of an individual boarding float section; not to exceed 1” max.

2. Live Load: Boarding floats are to float level in the water within the following limits:

a. Uniform Live Load (ULL) shall be 20 pounds per square foot (20 psf)

Section 355113 – Page 3

b. Live Point Load (LPL) shall be 450 pounds, applied 12 inches away from the edge of the boarding float.

3. Freeboard: Boarding floats shall provide the freeboard under the loading conditions listed below, with no more than 1” loss of freeboard after one year of service.

1. Dead Load Only (DL): 14 inch minimum / 20 inch maximum to the top of deck.

2. DL + ULL: 10 inch minimum to top of deck

3. DL + LPL: 13 inch minimum to top of deck

4. DL + ULL + LPL: 8 inch minimum to top of deck

Due to the variances deck construction, the contractor shall furnish freeboard calculations for the boarding floats for approval. The calculations shall bear the seal of a Registered Professional Engineer.

4. Wind and Wave Loading (WL) on the projected area of a vessel/dock combination applied as discussed in the Layout and Design Guidelines Handbook and the following:

6. The floatation units shall be designed to maintain their desired buoyancy and freeboard even if structurally damaged.

7. Float modules shall be designed so the section will neither rack nor twist in torsion under extreme design conditions. This system shall allow easy connecting and disconnection between individual dock modules.

8. The contractor shall demonstrate by in-water test or written calculations that the system will not tilt (list of pitch) more than six degree from horizontal when a concentrated load of 450 lbs is placed anywhere on the deck when assembled in a configuration similar to that shown on the contract drawings.

9. Neoprene PSA isolation strips (minimum 1/8 inch thickness) or other non-ferrous material shall be used to separate all aluminum and galvanized steel parts and other miscellaneous items to prevent corrosion or reaction between metals.
