**************************************************************************
Align bents before bracing is placed. Provide bracing of sufficient length
to provide a minimum distance of 200 mm 8 inches between outside bolt and
end of brace. Bracing and girts shall bear firmly against piles or timber
to which secured. Place fillers to avoid bending the bracing more than 25
mm one inch out of line when bracing bolts or other fastenings are drawn up
tight. Built-up fillers will not be permitted. Make filler a single piece
of the same treated lumber as that in the brace, with a width of at least
150 mm 6 inches and a length of at least 300 mm 12 inches. Bolt ends of
bracing through pile, post, or cap with a bolt of at least [20] [25] mm
[3/4] [one] inch [the indicated] diameter. Bolt or boat spike intermediate
intersections as indicated.
3.1.6
Caps
**************************************************************************
NOTE: Recommend use of 25 mm one inch diameter
dowels, bolts, and drift bolts in underwater or
splash zone conditions.
**************************************************************************
**************************************************************************
NOTE: This paragraph is based on timber caps on
timber piles. Delete or modify this paragraph as
necessary to accommodate other systems.
**************************************************************************
Prior to placing caps, prepare tops of posts or piles according to
paragraphs entitled, "Field Treatment." Place timber caps to secure
bearing over tops of supporting posts or piles and to secure even alignment
of their ends. Secure caps by drift bolts of at least [20] [25] mm [3/4]
[one] inch [the indicated] diameter extending at least 225 mm 9 inches into
posts or piles. Place drift bolts in the center of pile or post.
3.1.7
Stringers
Place crown up and, if possible, the better edge of deck stringers down.
Tops of stringers shall not vary from a plane more than will permit bearing
of the floor on stringers. Butt-joint and splice outside stringers, but
lap interior stringers to take bearing over full width of cap or floor beam
at each end. Break joints if stringers cover two spans. Toenail or drift
bolt stringers as indicated. Stringers may be of sufficient length to
cover two spans, except on sharp horizontal curves. Between stringers,
frame and toenail cross-bridging or solid-bridging at each end with at
least two nails for cross-bridging and four nails for solid-bridging. Make
size and spacing of bridging as indicated.
3.1.8
Decking
Make decking of a single thickness of plank supported by stringers or
joists. Unless otherwise indicated, lay plank with heart side down and
with tight joints. Spike each plank to each joist or nailing strip with at
least two spikes. Provide spikes at least 101 mm 4 inches greater than the
thickness of plank. Place spikes at least 63 mm 2 1/2 inches from edges of
the plank. Cut ends of planks parallel to center line of pier. Grade
planks as to thickness and lay so that adjacent planks vary less than 2 mm
1/16 inch.
