It's one thing to say, here's the specification, however like construction you get to the site and then you realize oh shit, this isn't going to work. So they amend changes to make it work. In a perfect world they should have gone back to the engineers/architects and reported their findings so they can make the changes to the white paper accordingly. But this almost never happens, same thing in the tech industry. That's why when they go back on site to fix a pipe leak they drill into the electrical conduit because they moved the whole line to the right 3 feet and never told anyone.
