Hiya Chode! Before Ret. building these suckers was my gig. 75 floors was my personal ‘high’ lol!! The common response to another worker casually asking you in passing, “Howzit going?” was “D.L.D. Baby”, (Don’t Look Down!!! And you learned that little trick fast as a young apprentice, and It really worked to help with the fear.) This Jap 1 mile high ‘skraper is going to be one heck of a project....if it even ‘gets out of the hole’. wait and see I guess. The Burj is still my favorite looking Tower of the newer designs.
