Intracoastal Waterway Electric Improvement Project

Estimated Dates & Work Schedule

Anticipated Start Date: 2013-04-01
Anticipated End Date: 2018-10-31

Project Objective

JEA rehabilitated the steel H-pilings that support 7 JEA electric transmission towers which span from near the Atlantic Boulevard Intracoastal Water Way bridge to the area around 7 Pine Island, the Atlantic Highlands neighborhood and Hogpen Creek. This work was considered standard maintenance for these types of structures and is expected to last over 30 years. This construction did not affect electric utility service in the area.

Project Work Details

The work included the chipping of the existing concrete encasements to expose the H-piling; sand blasting the H-piling; drilling holes in the existing H-piling and bolting on new steel as required. The contractor also encapsulated the H-piling with a fiberglass and epoxy grout system for long-term corrosion protection.

    Construction Conditions

    This project involved excavation and jetting around each tower to expose the H-pilings in order to perform the necessary structural repairs. The contractor was required to do some minor dredging to access several of the towers. During the repair work, the contractor used excavators, pneumatic chipping hammers, hydraulic drills, sand blasters, generators and air compressors to complete the work.
