Why is this project one of the most challenging to date?

Ask and you shall receive. From one of the carpenters on the project:
The core wall has continuous #14 rebar from the mat slab to the top of the structure. It’s spacing started out @ 6”. It is coupled all the way from bottom to top on each face of the walls.
It is 14K concrete with huge workability-issues.
The wall thickness is only 14”. When combined with the #14 bar, huge embedded plates and only 3/4” coverage, the challenges were endless.
There’s more, if you’d like...

#14 rebar in a 14-inch wall seems like one of those weird engineering results that didn't get much thought. I can imagine the grumblings between the construction side and the engineering/design side. Also, I don't deal with ACI code, but is 3/4" cover really acceptable?

Wow. I remain a fan of the take-a-risk design approach that BU went for here, but I admit these pictures make me a tiny bit nervous. This building will be stunningly prominent, really hope the risk pans out...

It will be very exciting and wonderful to look at from many angles and distances. (Although I’m not sure what it will be like at the front door!)

I wonder if in the 1960's was Warren Towers a "take-a-risk" design??
