Have worked in Germany and indeed in Berlin and these issues are not uncommon on large capital project as has been said eg Rhine - Danube link canal ran years late, however at least it was done unlike LHR 3rd runway !
.
Have to say that canceling this late is unusual and I would have thought that these inspections from my knowledge would have been on a rolling program so you would have known somthing was wrong earlier than this late date. Will make enquiries with our German suppliers and competitors to try and find out more as some where on this project
