I live a couple blocks away from there. The roofs are flat in that whole complex aside from the Golden Rondelle Theater. I don't know if they've since fixed it since I see they've done some redecorating on the upper floors in recent years and I haven't thought to ask anybody who works there, but for a long time they couldn't have people working in a large portion of the central tower due to inadequate fire exits.

Coincidentally, I recently put up a profile coffee roasting planner built on cubic splines. The constraints of the cubic spline match up nicely with the behavior of coffee in a roasting machine so doing it this way gets you plans that are easy to follow and fast to put together or edit. This one is just done as a web site, but prior to that I'd been using a prototype in C++ (unreleased because no UI) for several years. Try not to look at the code too closely, not a web dev. https://crucs.net.
