General contractors and subs review drawings for these problems during pre-construction. The earlier a problem is found, the less it costs.
A mechanical sub may find a duct that cannot fit under a beam. An installer may find equipment that cannot pass through the door.
When you see a problem while you bid, write it down with the sheet number. Send an RFI if time allows.
If it stays open, price what is drawn and state a qualification. Do not price your own fix in silence.
