philly collapse, chicago events

June 6, 2013 § Leave a comment

Yesterday’s collapse of a four-story building in Philadelphia looks like an unfortunately classic SCI-TECH teaching moment.  As I explained to Turi Ryder on WGN radio last night (audio, somewhat unbelievably, here), from photographs taken a day or two before the incident it looks to me like the demolition had removed a lot of floor (read: horizontal diaphragms) compared to the amount of free-standing party wall left.  And brick walls need  bracing, otherwise they get flimsy quickly.  Good questions, and a real thrill to be on WGN.

Off to Chicago tonight…I’m scheduled to be on WGN-TV midday tomorrow, and we’ll have our semi-regular planning meeting for the 2015 Construction History Congress on Saturday  evening downtown (interested?  We could use a few more volunteers…).  The highlight of my weekend, though, will be Printer’s Row Lit Fest, where I’ll be in conversation with Gary Johnson, President of the Chicago History Museum, on Sunday afternoon.  That talk is sold out (!), but come by the University of Illinois Press book tent on Dearborn St. afterwards to say hello–I’ll be signing books from 2:30-3:30 or so.

Also pleased to mention that I’ll be giving a lunch talk at the University Club (Holabird and Roche classic) on 20 June.  Details here
