• Contractor to supply and install a 2" x 4" blocking board (spaced no more than 3' on center), along with a continuous 2" x 4" to create a 3" high 'curb' along the entire length of each side. The seams of these boards shall be generally at the middle point of existing deck sections — and the seams shall be matched by a 45° degree cut directly over the blocking board. (See example reference below.) There shall be three to four fasteners screwed into each end of the upper 2" x 4" where they join. • Contractor to supply and install bracket hardware, mud foot plate and pipe, with a 5/8" set bolt mechanism for adjustment for all areas where existing deck sections must be removed near the (north) portion by the bridge, (scope of removal at the Contractor's discretion). (See Appendix for the referenced sections to be removed.) All components to be hot dipped galvanized, and the pipe to be 1 1/2" schedule 40, hot dipped galvanized. This will be used to achieve significant adjustment for removed sections as noted above, or other areas where the existing deck sections do not provide enough support, or shimming is not practicable. The City projects that this technique will be required at 10 or more sections of the existing boardwalk. • The existing bridge is 8' foot wide and does not need replacement or over decking. The new decking shall meet this bridge section, with the Contractor to field engineer the joining of the new decking to the bridge decking (or full 8' foot approach area), such that there is no vertical differential where new deck boards meet the existing deck board(s). • Contractor to supply and install two, 8' foot hinged hot dipped galvanized diamond plate (or flex resistant aluminum diamond plate) at beginning and end of boardwalk (plates to overlap onto the bituminous trail at the north and south). 4I
