Large footers on clones is common.Take a look at the footers at the bottom of the drop on the latest Batman clone:http://www.rcdb.com/installationgallery1365.htm?Picture=9Compare them to the footers of the original B:TR at SFGAmhttp://sfgamworld.com/Photos/SFGAm ... 2_JPG.html
This is a little OT.. But what is with Great America and using the footers with the Galvanized Sheath now? I know V² has it, I think Déjà Vu has it, but I think all of their previous rides don't. Did they figure out that using the protective covering would help the footers last longer? Or is it just the location they are building, because all 3 new rides were built around water.
Maybe all that dirt is too cover up some of the parking lot and when all the dirt is filled in the footers won't be that high from the dirt. That's just a guess, I have no clue if they can cover up cement with dirt anyways.l
I think that it might have something to do with the regulations of the city or town. They might have some law to how the footers have to be. This could be on some type of coasters
The footers in Georgia are much smaller because of climate differences. In Georgia, it rarely freezes, so the footers don't have to be as big or go as deep into the ground to withstand frost. It's the same way with deck foundations on your house, etc.
They are on swampy land right next to the lake. As you can see on Serial Thriller, the supports are actually on piers, not footers. I'd imagine those pylons supporting them go quite deep. Batman is right next to it, so thats why both have huge footers. I never noticed how big any of the other coasters' footers are. But those two were on the most swampy land, by far. It added a lot to those two rides.
