Re: jailbreak through CMU

[Subject Prev][Subject Next][Thread Prev][Thread Next]
How (almost) timely; I just finished a value engineering exercise on a jail. Those cells were precast concrete - we didn't suggest any changes there.

I also saw the ungrouted cell with interest. I once had an owner-building as me how she was supposed to get the rebar into a window jamb after she set the solid precast lintel. She was quite surprised to find out that she had to grout those cells - she expected that putting the rebar in would be enough!
