Ferrovial would do itself and DIA a great favor by seeking to renovate either ORD or EWR.  Chicago and Newark would be the type of players that understand the machinations for which Ferrovial has been charged. 
Somehow some 30 years or so ago Denver was able to come up with the plans for DIA, but now cannot continue to provide flyers a pleasant uncluttered experience...hogwash!
There are plenty of talented individuals out there that could get the job done, working with the various government and private entities.  Airports are cash cows and the goal of many is to squeeze as much cash per square foot as possible, ex. EWR, walking down the concourse I was mistaken for a waiter as I weaved between tables on the way to the gate.
There was a guy, Paul Green at LAXWA that restructured LA airports and gained the highest S/P credit rating of any airports in the U.S. 
This smacks of Chicago or Newark, anyway the disaster will happen on some other one's watch, keep fiddling.
