Below is a link to the project page on the Six Flags Green Lantern Roller Coaster in New Jersey.

Huge structural loads were required for the roller coaster. Force Concrete of South River, New Jersey, used Fastfoot® to form these footings. The fabric reduced forming costs and eliminated the need for an inventory of plywood forms.
Take a look, I would like to hear your thoughts.

Thanks a lot for sharing the link, i would be having a look at this for sure.....
