I come up with this because I had searched the web quite intensively for inspiration for Sock's industrial set but couldn't find anything useful really. I did search for the wrong keywords, I guess.
Now, by accident I stumbled upon http://www.modernruins.de and found some photos of an abandoned industrial complex that could fit. Only the shapes matter, not the state of the building.

Original images are hi-res, 5600*x. To choose different places go to "Datenbank" at the top.
When I saw this I thought of the hh3 singlemalt texture set:

There are 1800+ photos of this abandoned sanatorium alone, but 900*x at max.
And their section for industrial stuff: http://www.fotocommunity.de/motive/indu ... afie/17314
Sorry for it all being in german only.
