I was there, nearly 10 years ago, when they announced the campus redesign. All of the buildings were outdated and in disrepair. Ford announced a major campus design for it's product development campus: new parking buildings, new buildings, and renovations for every existing building.
Work began, everyone was excited. Then unexpectedly, Billy Ford announces that he had Ford buy a Train Station (ironic). Questions began as to what was going to happen with the campus redesign. We were assured it would still continue and it did; albeit scaled down. Instead of tearing down all of PDC, only some of it would be torn down and instead of a complete campus redesign only one new building (beside car parking lot) would be built on the campus.
Everyone waited patiently for the new PDC building to be built. And that's what we were calling it, the 'new PDC'. Then only a couple of weeks before the building was set to open up. Ford leadership decided that they liked the new building too much to allow it to be just another engineering building and that it would be their new headquarters.
What was wrong with the old World Headquarters? Nothing.
Ask yourself, why didn't they announced that it was going to be the new World Headquarters years ago when the construction first broke ground? Why wait until weeks before opening to announce that it will be the new headquarters?
FU product development, that's why.
Have fun remaining in PDC where the air conditioning doesn't always work. Shout-out to the IT support teams that had to work out of that Atrium. Hopefully they'll let you move into the new building and you won't be subjected to that humid stale air all day.
