Underwater Facilities Inspections and Assessments at U.S. Naval Weapons Station, Yorktown, Virginia.

The objective of the underwater facilities assessments was to provide a generalized structural report and assessment of the principal berthing facility at that activity. That facility is the R3-Fleet Weapons Pier Wharf which is the only facility used to load and unload ammunition to and from ships and lighters. The inspection was limited in scope to a Level I investigation using visual andor tactile means of examination, providing still photographic documentation where feasible. The inspection objective was to provide a general assessment of the structures physical condition documenting any mechanical, biological, or corrosion damage, with emphasis on any advanced stages of deterioration. Because of the huge amount of piles in this structure, over 4600, a random sampling technique was primarily employed to select and inspect about ten percent of the piles, with heavier emphasis on the older sections of the wharf.
