Q: There are so many major construction projects going on in Manhattan. Comparing the multistory steel frameworks, however, makes one curious. In particular, the new NBAF building and the South Fourth Street project have beams and girders that one might find in a fort. They look very substantial — strong enough to resist a tornado. On the other hand, the steelwork at Aggieville’s new hotel looks spindly and much less able to resist Kansas’ occasionally destructive weather forces. We have to assume that all comply with building codes, but the question remains: Why does the hotel differ so noticeably from the others?
