  •  last week's photos (10+ / 0-)

    showed the "story poles" which are set up and braced plumb in the corners to hold a taut string which is the guide for the mason. Those walls are within 1/4 inch of true, and is not hard to accomplish, once the mason learns to respect the string.

    •  FOr the rest of us that do not build in adobe, (10+ / 0-)

      there is a standard concrete block for forming bond beams. It is "U" shaped in profile, is laid up like regular block, and then filled with concrete after some rebar has been placed.

      Since stair towers in commercial buildings typically require a one or two hour seperation (and they take a lot of abuse), it is common to build them out of concrete block. Engineers will specify a bond beam at every floor level to help tie the entire structure together.

        I have to say that seeing a 150 unit wood-frame apartment building scares me.  

        Seeing these large stick built structures recalls a conversation with a friend of mine, also an engineer, about 15 years ago who said on seeing such a building that he'd never live in it.  

        I might not go quite that far, probably saying it was OK in its first 20 years after being built if it were fully sprinklered.
