Hal Jones Leads Multiple New Development Projects on St. Johns River in Jacksonville

Bulkhead Rehabilitation Project

Post Street Dock

Hal Jones has a long-standing working relationship with the city of Jacksonville to support their plan to connect its many waterfront communities with several new docks along the St. Johns River. One of those docks is the new Post Street dock located on the west side of the river.

The dock, designed by SF Marina based out of Virgina, was installed by Hal Jones ( photo below top). Concrete pontoons are a key feature of the dock and include a wave dampening design that, along with their substantial mass, allows them to endure heavy commercial use and wave action. Jacksonville has been hit by significant storms over the last few years, and that was taken into consideration when designing the dock.

Piles as deep as 40 feet into the river bottom, and 20 inches in diameter, secure the pontoons. A 42-foot aluminum bridge and 36-foot hinged gangway connects the docks to the shoreline ( photo below bottom).

Hal Jones Contractor has begun construction on a new bulkhead rehabilitation project for Fincantieri Marine Repair in Jacksonville, Florida. In phase one of the $30 million project, 80 ft. pipe piles will be joined together with interlocks to form a pipe-on-pipe main bulkhead. The new pipe piles will be driven as close to the old sheet pile wall as possible, then the entire system will be encapsulated in concrete.

Each pipe pile will require a preformed drilled hole in the dense limerock river bottom. An existing relieving platform will be mostly demolished, leaving only the pile supported framework (photos above and below).

The new platform will then be repoured and extended. This phase of the project will consist of 350 feet of wall, approximately 10% of the total 2960 feet. This wall portion will allow a -54 elevation dredge cut to house a future drydock.
