To add what Jerf said, the edit to my original comment says:<p>&gt;On a small note, this is &quot;finalized&quot; pdf but in reality it will change when implementation occurs.<p>It&#x27;s one thing to say, here&#x27;s the specification, however like construction you get to the site and then you realize oh shit, this isn&#x27;t going to work. So they amend changes to make it work.<p>In a perfect world they should have gone back to the engineers&#x2F;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.<p>That&#x27;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.
