Re: Lack of long term investment in decaying infrastructure?
There is a possibility that the management in charge of maintaining the structure were hoping to find an engineering company that gave the "right" answer, which would mean not spending any money. So they asked one company after another.
I find that when manglement types ask a question, and you do not give the "right" answer, they will ask the same question again, but phrased differently, and keep doing this, in the hope that you eventually change your mind. This is of course how incompetent and dishonest firms are awarded contracts, rather than competent and trustworthy firms.
