I don't think it's a movie. For one thing, movies generally don't need surveyors. Secondly, there's a temporary construction fence and a bulldozer there right now, again, not needed for filming. I also can't imagine a parking structure. There's still a large amount of surface parking around, and just can't see the financials being there to justify a parking garage.
On a related note, I found this on the web back from 2010 that shows the surrounding plots and where the fence is was not for sale back then.
