Maybe half-invented, but I read an architect's memoirs some years ago and he was saying how around the 1940s there were often cases when he and his chief-architect/supervisor at the time were actually chased out (like, physically) from the construction sites whenever they were coming in to add/make some changes that the constructor was considering as being too over the top/unrealistic. We need for that attitude to come back, at least in a metaphorical way, otherwise we'll continue being stuck with projects like this one.

Why would you chase the architect with his insane ideas away when you're getting paid by the hour and the project must be completed at some point because there's no alternative for the government? Unfortunately nobody appears to come off as not corrupt or idiotic in some way in this story.

Because most workers, even though they get paid by the hour, actually want to see the job done. Plenty of people want to do a good job, so when they see someone coming in and adding to the workload to make the job worse they’ll, naturally, tell them to piss off.

There’s also the issue of reputational damage.

Everyone associated with BER is now tainted by association.

Even by the claims of your article, it doesn't sound really like it was his fault. The system was designed to a specification, whether or not the architect was given too much free reign is entirely on the board.

If you hire a design team to create a car with a massive hole where the engine and wheels should be, because it is more "clean", and then neglect to hire an engineer to check their work is feasible, is it on the design team or on you being incompetent?

You can say all you want "hot air naturally rises", true, but I doubt an architect has the training to be a safety engineer, and before you say "oh well that's obvious", consider that heavy objects naturally fall to the earth, and yet we have airplanes.

They had a design which would work, but nobody in charge actually did the legwork of bothering to check if it was feasible or not, and/or bungled it so badly even if it were feasible it was like attaching a helicopter to an airplane and then wondering why it didn't fly...
