In addition, <br />finger piers shall have their outer ends at least level with but in no <br />case more than 2" higher than the elevation of the main pier at their <br />plane of attachment. The ends of finger piers shall be as level as <br />practical but in no case shall a cross slope of more than 3/4" for <br />each 4' of width be tolerated under dead load conditions. <br />w <br />A uniform live load of not less than 30 pounds per square foot on <br />bridges and on the deck and structural frame of the floating piers <br />shall be used. Minimum live load for flotation shall be 30 pounds per <br />square foot. Finger piers must be designed to withstand a 400 pound <br />concentrated live load from the end of the finger pier without a <br />loss in freeboard of more than 4”. With a 200 pound load on one <br />corner of a finger pier there shall be no more than a 2" difference in <br />freeboard across the end of the pier for each 3 feet of finger pier <br />width. <br />Combined dead load plus live load for piers and bridges shall be the <br />actual dead load including utilities plus 30 psf live load. However, <br />for purposes cf calculation, the combined dead load plus required 30 <br />psf live load shall never be calculated as being less than 50 psf. <br />Bridges shall be so designed that maximum live load deflection of the <br />bridge is limited to 1/180 of the span. Extra flotation of the same <br />general type and design used for the floating piers shall be installed <br />at end sections as required to compensate for end reactions of bridges <br />due to combined loading. In no case shall the supporting pier module <br />at the bridge connection be less than the designated freeboard under <br />combined loading nor more than 2" above the freeboard shown on the <br />approved shop drawings under the full deadload including utilities. <br />Pier manufacturers shall provide piers with dead load freeboards of <br />not less than 22" or more than 26" (4" tolerance to allow for <br />variations between manufacturers). However, actual dead load <br />freeboard shall not vary appreciably from the freeboard designated on <br />the manufacturer's approved shop drawings with piers presenting a <br />reasonably level, flat, even surface to the eye under dead load <br />conditions. As indicated, main piers shall be reasonable level, but <br />in no case shall a cross slope exceeding 1 1/2" in 8' of width be <br />tolerated under dead load conditions. At the design load of dead load <br />plus 30 psf live load a freeboard of not less than 10 inches shall be <br />maintained. <br />. / <br />- 5 -
