Figure 5-10 Timber Structures and Attachments (Above Water)
___ Check for cracked, rotted, loose or worn decking or string pieces, loose
hardware, soft spots in decking (Figure 5-6), and termite or pest
___ Check the tops of fender piles and visible chocks and wales for physical
damage, dry rot and termite or pest infestations.
___ Check horizontal and vertical alignment.
___ Check for missing, broken, or loose connections; obstructions; and other
hazardous conditions of curbing, handrails, and catwalks.
___ Check bollards, bits, cleats and capstans for wear, breaks, rough or sharp
surfaces or edges and missing or loose bolts.
___ Check deck drains and scuppers for loose, missing or broken screws,
standing water, and other deficiencies.
___ Check manhole covers and grating for rust, corrosion, bent or worn hinge
pins, and other damage.
___ Inspect asphalt deck coverings (if applicable) for cracks, holes, and other
___ Check ladders for rust and corrosion, broken, bent or missing rungs, and
rot, termite or pest infestations.
___ Check grounding connections for tightness.
Exposed Area Under Pier or Along Wharf or Dolphin Assembly
___ Check wood stringers, pile caps, bearing, batter and fender piles, for
missing or broken members and evidence of fungal decay and insect
damage. Check for loose, fractured or missing wales and chocks.
___ Check dolphins for broken, worn or corroded cables and cable connectors;
and corroded, loose, broken or missing wedge block, chafing strips and
bands, or chock bolt hangers.
___ Check dolphins for poor vertical pile alignment.
___ Visually examine piling and other wood in the splash and tidal zones for
marine borer damage.
___ Sound the pile areas with a hammer and carefully probe with a thin-pointed
tool such as an ice pick.
___ Check for pile shrinkage, overloading damage, connector corrosion,
abrasion, and ice heaving damage.
___ Take a small boring for laboratory analysis using and increment borer if an
area of rot or marine borer damage is in question. Once the core is
extracted, seal the hole with a creosote treated plug to prevent easy access
of borers to the interior of the pile.
