This isn't entirely true, yes they have the whole pitch moving thing, but technology wise we may be a little further ahead. The issues at Spurs were caused by design changes and poor revision control. I believe that the entire fire alarm and life safety systems had to be rewired due to changes that had happened throughout the build, but they hadn't been picked up by the installation team as they were working off old drawings. That may not have been the only service to be affected, but thats the one I heard about. This is the risk with meddling after design freeze, something that Spurs did a LOT of.
