Book excerpt: An underwater facilities inspection was made of certain facilities at the North Island Naval Air Station, San Diego, California during the period July 20 to August 25, 1984. The assessed facilities were: The Old Air Station Bulkhead, The Carrier Quay Wall or Bulkhead, Pier Bravo, and Pier J/K. A condition of moderate to severe sulphate deterioration of the concrete was found in the piling to such an extent that is is recommended that the pier live load be restricted to 100 psf (pounds per square foot) and truck cranes in excess of 15 tons be prohibited. The pier is adequately supported against earthquake forces (as defined in NavFac P-355) applied perpendicular to its principal axis. However, the piles would not be expected to support the pier in the event of earthquake forces applied parallel to the principal axis.
