As one of the five photo judges for this year's photo contest I have to say thanks to everyone who submitted. By "have to" I mean really want to. Aside from a few strange submissions, all of the photos were worthy of serious consideration and it took the judges several hours, in a small, dark room, debating amongst ourselves, before we emerged with the winners.

And even so, we still had a long list of first runners-up that we just didn't feel like tossing aside without sharing, so, we've brought them to you here. Take a look at the slideshow and be prepared for another visually astounding tour of construciton sites around the world. The images appear in random order.
