​Issue

The 30-inch prestressed concrete piles for the footings in water and highly corrosive environment were detailed with conventional reinforcement to support stay-in-place forms.

Action Item

For future projects in corrosive environments detailed with this type of footing connection in water, ensure that the falsework reinforcement is epoxy-coated.

​Issue

The high tide elevation was above the bottom of footing elevations.

Action Item

Structures will revise the Design Manual to state that bottom of footing elevations shall be set above the high tide elevation.
