American Steel, Granite, Limestone
- 225 million pounds (100 million kilograms) of American steel
- 490,000 ties and transporting 2.35 million tons (2.1 million tonnes) of granite and limestone by 20,000 railcars
- 2 million spikes and bolts will be hammered and put in place
Two Concrete Box Tunnels
- Minimal disruption while the tunneling is underway
Concrete Tunnel Construction
The tunnel construction box-jacking method can build a tunnel for a train in the fraction of the time it would take using conventional methods, making this method safer and more economical.
Box-Jacking Method for Tunnel Construction
The box-jack operation at Goldenrod Rd., just east of Orlando International Airport, took just two weeks to complete compared to traditional underpass construction, which would have shut down local roadways for nearly a year.
Cost Saving Solutions
The unexposed box tunnel is buried underneath South Goldenrod Road making the concrete finish not an issue. EFCO was able to offer a cost-saving solution with the use of “Shore Grade” (Non-Architectural) PLATE GIRDER panels.
As you know, we recently completed the third box push in North America (the largest, longest and first under a roadway) four days ahead of schedule. This accomplishment was done even with an eighty-three hour delay in the middle of the push. This feat would not have been possible if not for the help and cooperation of our subcontractors and vendors. The groundwork for the successful operation was laid out over a year ago, with many hours of work and planning ahead of the actual push. I just wanted to take a minute and thank the team at EFCO for their contribution to making this task a success. Your contribution to helping us will not be forgotten.
