GENERAL CONSIDERATIONS. The fundamental purpose of any
inspection is to provide the information necessary to assess the condition
(capacity, safety, and rate of deterioration) of a structure. Waterfront structures to
be inspected include: piers, pilings, wharves, quaywalls, fender systems,
dolphins, and drydocks.
Inspection Objectives. Inspections are classified according to the
objectives. These include:
Baseline - to obtain data on a facility that has not been inspected.
This inspection involves the greatest "pre-inspection" effort.
Routine - to obtain data on general condition, confirm drawings,
estimate repair costs, etc.
Design Survey - to obtain data for specifications or for detailed cost
Acceptance - to obtain data confirming that a repair has been
completed according to plan or specification.
Research - to obtain data on deterioration rates, etc.
The usefulness of an inspection depends on establishing a clear and
complete record. Although the level of inspection will determine the extent of
information to be provided, in general the inspection will address the:
Identification and description of all major damage and deterioration
of the facility.
Description of facilities inspected including updated layouts of pile
plans (which occasionally differ significantly from the drawings
available at the activity).
Documentation of types and extent of marine growth, if applicable.
Water depth, visibility, tidal range, and water current.
Assessment of general physical condition including projected load
Recommendations for required maintenance and repair (M&R).
