The project site was previously developed with lightly loaded, two-story frame structures with conventional shallow spread footings. These structures and footings were demolished to prepare the site.
The subsurface conditions included 5 to 8 feet of fill to underlain by peat, marine clay, silt and sand, and bedrock. The fill layer consisted of sand with brick and concrete fragments. The top of the peat deposit was 7 to 10 feet below the ground surface The peat was very soft to medium stiff, and ranged in thickness from 3 to 9 feet. Bedrock was present at depth ranging 64 feet to 86 feet.
