The pile schedule included 7,600 LF of 36-in steel pipe pile and diameter and 6,600 LF of 30-in steel pipe pile. Pile installation called for 36-in and 30-in diameter socketed piles up to 175-ft long and then socketing using drill equipment, 15-ft into bedrock using a down-the-hole drill utilizing drilling shoes to advance the pile while drilling. Piling was installed using a combination of land and barge mounted equipment. Extensive overburden and complex soils conditions consisting of deep sands, silts, and clays required drilling. The shore side was supported by construction of a 400 LF OPEN CELL Bulkhead/ Seawall consisting of PS31 20-ft sheets comprising 11 cells backfilled with 30,000 CY core stone, 3,000 CY filler stone, and 10,000 CY large armor stone.
