Abstract:

Each facility was inspected by a team of engineerdivers using a combination of visualtactile and ultrasonic techniques. Critical elements were photo-documented. Wharf ALPHA and Pier CHARLIE appear to be in excellent condition, except for some localized structural damage or environmental deterioration. Wharf ALPHA has some cosmetic spalling on several piles. It is recommended that these areas be patched with an epoxy grout to insure adequate protection of the prestressed reinforcing steel. In Pier CHARLIE, one pile has suffered damage due to impact. It is recommended that the pile also be repaired. Loadings in the vicinity of this pile should be limited to dead load only, until repairs are performed. Pier BRAVO has seen more deterioration than either Wharf ALPHA or Pier CHARLIE. The concrete encasements are in poor shape and, in some areas, are not protecting the steel H-piles from salt water corrosion. However, steel thickness measurements indicate that the pile foundation is adequate to handle the imposed loads. A reinspection of Pier BRAVO should be conducted in three years to document any further deterioration.
