Hey don't come in this thread posting with knowledge of a coaster building process. Word has RV repairs have been done a few times as well. Two rides with clearance issues opening in the same land from WDI is not good.
The collision issue has been around. Some of the first test runs had it hitting the station pretty good. It seems there are more clearance issues than they thought. Simple fix. Quick fix. But still an issue that shouldn't coming in at this point.
Dude, just eat your crow.
Based on that reply, it sounds like you are doing just that, Bulls!
The basics?
The ride vehicles are hitting what they shouldn't. Not just once.
Scenery and cars are being fixed but obviously this wasn't planned. Also being adjusted is the envelope to ensure it doesn't happen again.
This is not T&A. Originally we were a few dozen hours away from softs. Or in laymans terms they messed up and are now trying to fix it.

My guess from a distance is that there has been some settling of the infrastructure due to the shear mass of the rock work and coaster steel. Hard to plan for that.

Do you know if there is any "intelligence" in the ride vehicles themselves, or do they rely 100% on physics for their movement control?
It would have made sense if the vehicles held a battery charge and could have internal electromechanics that could throttle the swinging and even lock the cars down when approaching a lift or platform, to ensure they're in the correct position.
Never from the beginning did I think that they could let these cars free-swing AND be able to keep them perfectly vertical when approaching something like load/unload.

The margin of error used for the clearances should have more than compensated for any possible construction "settling", which should be immeasurable.

The difference is that we could see almost everything that happened at EE because of the height at which it was happenin. The 7DMT has been built behind walls and we do not know what happened and when because of the lower height at which it happened.

Can I reserve my loss of limb 45 days in advance?

Good point. But then, it would have to be triggered by something in the track system, right?

People demand immersion and it shows up in the tolerances which seem to get more exacting over time. I think this is also driven by safety concerns. For instance on Dumbo I think the tolerances were so tight to keep guests' feet from slipping into the gap. But until the rides are built it is tough to account for settling. It is not like they are building these things on an assembly line.
Considering there have been rides built on those lands for decades, settling would not have been difficult to compensate for. And if it was such a concern, perhaps they should not have apparently waited until the ride was set to open before testing for such concerns.

So you are challenging someone who works in the construction industry on the topic of settling tolerances for new construction? Let me know how that works out for you.

As good as they are, there's still no way to completely account for the real-world in even the best CAD/CAM tools. Sometimes it's just one of those things that has to be tested once built to accommodate for things that may shift once built or perhaps adjust for the builder's slight mis-calculation.

*playing devils advocate here*
That land was the plot of 20K lagoon. The land had to be built UP to standard park elevation using backfill from lord knows where. So in reality this is virgin land and very unpredictable.

Wow. I thought the tests and adjustments were just to increase clearance if someone reached an arm out. This sounds a whole lot worse. How did they let people ride this thing if the ride vehicles were actually hitting things? That seems almost negligent on the part of Disney. I don't care what kind of waiver people sign if there is something that blatant wrong and god forbid someone is hurt its a pretty slam dunk lawsuit to win. Waivers don't get you out of gross negligence. Luckily nobody was hurt. Thanks for the updates @marni1971 and @Scoutn757

People didn't ride this thing...actors did.

The engineers and architects, who place their stamp on the final set of plans, will ensure every tolerance, safety factor and margin of error has been taken into account.
If it gets built in a manner that's not compliant with the plans, that's on the contractor, and so is any issue resulting from the construction.
And in modern day construction, "settling" isn't acceptable. There's no tolerance even accounted for. The plans and specs require that the subgrade be prepared, and the foundations be placed, in such a manner that there is no movement. A coaster track can't settle - period.
