Any condition could have a direct impact on the time required to
perform an inspection, such as: the amount of biofouling growth on piles; ice; or
seasonal flooding. Any other unique feature or special problems that may be
encountered should also be noted.
The inspection plan should include CADD drawings showing individual
piles and other structural members. The inspection could use pile
numbering/designation systems often available on existing "as-built" drawings.
Usually, combinations of numbers and letters are used with the number
designating the bent and letter indicating the pile within the bent. CADD drawings
should also be developed for the above and below deck portions of the pier. The
existing positions of all topside bollards, bitts, cleats, capstans, utility covers, as
well as any under deck utilities and fittings should be shown on the CADD
drawings. A legend should be created to represent such things as the:
Degree of deterioration of individual structural members
Level of inspection given to designated portions of a facility
Shape of individual piles
Type of materials
Condition of bollards and bitts
Pile plans should be prepared for piers showing the lengths, widths,
and spacing of bents. The plans must also include the numbering system used in
the inspection and in the report, and these must be correlated with existing
drawings of the facility. Also include design live load data on all pile plans, if
available. Load testing of the pier decking, if heavy equipment or vehicles are
driven onto the pier, should be considered.
Particular attention should be paid to mooring hardware as it relates to
safe mooring of naval vessels during heavy weather. A more thorough treatment
of this topic is contained in UFC 4-150-09, Inspection of Mooring Hardware Draft
April 2001.
