Are you one of those people, like me, that watches documentary shows on building bridges, tunnels and skyscrapers... no one reading this on a blog gets to call me a geek without taking a hard look in the mirrored walls of this behemoth in Dubai. Yeah, I know, the outlandish architecture going on there is hardly news anymore, but a few weeks ago Burj Dubai hit its mark of 818m or 2684ft.
Check out the site for a whole bunch of pics and schematics with information on filling up the lake around the building and other finishing projects.
The pic below just shows how large this structure is. If you're really into this stuff, further Google searches will turn up a ton of information.
