This seems like a common problem not just in construction but in all parts of society. It very likely that plenty of engineers looked at the design of this and said that it doesn't work this way and that they were silenced along the way. Germany built massive transit hub train terminals in a matter of a year during the Nazi period(I forgot the name, but it was a transit hub for military equipment between Hamburg and Dresden I think), while today, this story here reads exactly like Stuttgart 21, where a decade long construction projects ends up with less capacity than the previous train hub. My dad was telling me about when he learned construction where there was the same guy responsible for building the stairs and sometimes that person would diverge from the plan because his experience would tell him that the design was wrong. I managed part of a construction project when I was working in Government in Germany and many of the subcontractors told me exactly the same thing, the guys designing the network, AFA and data center access control(Bosch), as well as the network cabling, and even the carpenter and the elevator company all told me the same thing. The architect sent them wrong specs and these guys said that, were they to change any of the specs they would be liable for any upcoming issue. The elevator company was the only one that looked at the specs and told his worker to change it and then in front of me told his worker that he would take responsibility for the change. It went beyond that, because the Architecture firm running the construction project actually told these subcontractors not to send us issues that they see, so until I started actively poking around they told me that they were told not to inform us directly. For all other building services engineering parts I had to get personally involved, finding the issues, then corroborate them with a second contracting firm only to then face an uphill battle to convince leadership of the decades of upcoming problems if we don't change them. This is the same reason people hire Accenture and EY we read in the other thread. As long as leadership doesn't know they're not going to be liable for all the crap that was installed under their watch. And because the contracting firms know that they will building things EXACTLY according to spec(or this case the construction tender). https://en.wikipedia.org/wiki/Stuttgart_21 https://en.wikipedia.org/wiki/Stuttgart_21
