Mind the gap. My latest project involves figuring out how this special entrance will be structurally detailed. The challenge is to provide support for the curtain wall, tie-backs for window washers to hook into, and support for a fancy 4-story piece of artwork generically called the chimes. Complicating the effort is the fact that a lot of the structure has already been built - thus limiting the design freedom. Oh yeah, and the client needs it all figured out by Friday.
