You will not get a keycard to get the treasure. Instead shoot the guy on the ground floor, as he drops the Oval. He has head armor so shoot his arm. When Sheva gets captured proceed as normal and pick up the topaz before you climb the crane. It will be up the stairs to your right after using the keycard.
Ok Thanks Dude!
I will try it now,will get back to you!
