Sullivan Extra-Heavy Timber Bulkhead
The Sullivan Heavy Timber Bulkhead Project - is unusual in that we used 16' long 9" head round piles on 4.5' centers with 4" x 12" stringers. The piling penetration is approximately 7 to 8 feet with the outer layer of sheet-piling penetration running approximately 6 feet on average before the second layer is installed directly behind it.
