well, you sort of have to wait. There is no guarantee that the check you made while building was exhaustive. People may not have payed attention, officers may have been bribed, certifications may not have accounted for problems that were not known at the time, unexpected geological activity may cause disruption etc. We have a few thousand years of managing construction, and we still have bridges that collapse all over the world. Sure, it's a small percentage of the bridges we build, and we should not stop doing that. I am not against landfills a-priori, they have their role, but considering them without issues is oversimplifying.
