Cooper Contracting

Norkfolk Southern – 201.0w Hunley Creek Bridge 2020

The Situation

The existing structure was a steel beam bridge with a steel ballast deck on steel H-piles. The proposed structure included a 96’ long welded through Plate Girder Span, and weighed approximately 384 tons. The new structure also needed to be raised 3 feet in order to alleviate flooding.

Why They Hired Cooper Contracting

Our reputation boasts not only a priority on safety and excellence, but also timeliness. As a planned outage was going to be necessary for this project, Cooper Contracting was the best fit for the job.

Our design-build experience with Cooper has shown them to be actively engaged in the design process with the goal of finding solutions to complete work safely, on-time and within budget. These same values have also been demonstrated on construction of projects that were contracted by design-bid-build.

Our Solution

Due to the sheer size of the structure, the span had to be rolled into place during a planned track outage. We also planned for a 2-foot track raise to be completed concurrently with the installation of the new structure. This project was not only completed to our standards of excellence; it was completed early. We’d planned a 17-hour track outage to raise the track and completely replace the existing structure, but work was complete by hour 12.
