There is a sump in the pit, always has been. The building is only 5 years old. The sump somehow malfunctioned and failed to push water out of the pit.

A high water alarm would be intelligent.

I'm not sure where we stand on the billing/work completed, the elevator is in service though. Apparently there was a rust issue before the flooding event, need to get some more info from Thyssen on the timeline.

Thyssen has access to our maintenance personal they just failed to notify use in a timely fashion until significant damage was done.

Aside: Do you really use jack stands 4 stories high? Or is there some other mechanical method to secure the car?
