Analysis is to include a.Deterioration of the concrete and rebar due to corrosion, scour, abrasion or fatigue, considerations to include chloride ion contamination, alkali-silica reaction, sulfate attack, delayed ettringite formation, and the depth of cover over the reinforcing steel on key structural elements b.Settling, including the designation points for future survey so the structure can be monitored for settlement, the wing walls and pier walls as well as the bottom slab should be surveyed and compared to previous elevation data to ensure the dam is not settling. c.Seismic resilience, and d.Longevity of the structure. 2.An analysis of the risks to safety associated with the dam facility and its operation, including a.Pedestrian, bicycle, and auto movements on 5th Avenue b.Fall protection risks to staff, particularly related to active guidance of floating debris through the dam gates and maintenance of tide gate equipment c.
