• All new wood for the boardwalk shall be treated, but only the 2 x8 decking, the <br /> curb/bumper and corresponding blocking need to be brown treated. <br /> • If wood is not suitable for significant adjustment of any decking or does not have <br /> adequate structural integrity, in certain locations of the existing boardwalk, the <br /> Contractor may supply and install bracket hardware,mud foot plate and pipe,with <br /> a 5/8" set bolt mechanism for adjustment (as depicted on page 6). All components <br /> to be hot dipped galvanized, and the pipe is to be 1 1/2" schedule 40, hot dipped <br /> galvanized. If this system to be used at the Contractor's discretion, it shall be <br /> incidental to the job and within the scope of the Lump Sum proposal. <br /> • Contractor to supply and install a 2" x 4" blocking (spaced no more than 3' on <br /> center), along with a continuous 2" x 4" to create a 3" high `curb' along the entire <br /> length of each side. The seams of these boards shall not be opposite of the other <br /> side, and be generally at the middle point of existing deck sections—and the seams <br /> shall be matched by a 45' degree cut directly over the blocking. (See example <br /> reference below,page 5.) There shall be two to three fasteners screwed into each end <br /> of the upper 2" x 4" where they join. The blocking shall have at least two fasteners <br /> through and secured to the 2 x 8 decking. <br /> • The finished deck surface shall be level in both directions, and 9" 1/2 inches higher <br /> than the existing boardwalk over the south 102' (approximately). At the very south <br /> end of the new completed boardwalk, a treated wood rim joist shall be placed to <br /> 'cap' the new end. The bituminous trail will then be elevated (by others) to match <br /> the new boardwalk height. <br /> • At approximately 100' feet from the south end described above, the Contractor <br /> shall fabricate and adjust the north 30' of the new boardwalk to transition <br /> gradually from level (approximately 9" in height), to the precise existing height of <br /> the bituminous trail to the north. This shall be performed primarily by reducing <br /> the length of the 5" 4 x 4's within the 'spacer beam' depicted on page 7. <br /> 4 1 Page <br />
