Delaware River Port Authority, Ben Franklin Bridge Track Rehabilitation
The Benjamin Franklin Bridge, a suspension bridge spanning the Delaware River between Philadelphia, PA and Camden, NJ carries 100,000 vehicles and 35,000 rail commuters per day. When DRPA/PATCO needed to implement two long-term track outages totaling 110 days for major track reconstruction, strategic planning, cooperation and communication were essential. The project replaced all railroad infrastructure on the bridge, including electrical, fiber-optic, and signals systems, and repaired the underbridge and elements supporting the railroad tracks. The 30-year-old track was removed, and more than 13,500 feet of continuous welded rail and 9,000 new timber ties were installed.
Envision managed the contractor schedule, including performing a detailed review, providing a report on the Contractor’s baseline CPM, and doing monthly project update schedules. Envision participated in bi-weekly meetings with the DRPA, the Prime and Contractor. The firm also performed comprehensive document control using innovative technology to enhance access to and sharing of timely project information.
