    Architect acting as a structural engr and doing extremely poor job

    Thanks guys. All good suggestions. I didn't expect this to be fun. I'm not getting paid to review his design. I'm comparing my results to what's on his plans. Ron's right in that it is an obvious public duty. So far the roof joists and beams are oversized. The roof diaphragm, the columns and...

    Architect acting as a structural engr and doing extremely poor job

    I was asked to take over a project because the architect refused or was unable to provide enough detail to produce bar joist shops. I've just scratched the surface but already have found columns that are at 200% of allowable stress and the specifying of a 26 ga roof panel with no published...

    Calculator of choice?

    IRC 2009 Residential Foundation Reinforcing

    The wall acts as a deep beam when spanning soft spots. Doubt if it even gets past cracking moment. Rebar is for crack control. Mike is right. A little extra rebar is cheap. Owners hate lots of cracks in their walls.

    Sorry guys, the question became moot once the owner moved the lockers to the basement and put handball courts on the framed level.

    fee for precast parking garage

    JLNJ, worked that way for Kansas City Intl Airport garages. Structural Engineer was the Prime and everybody else were the consultants. That was a cast-in-place post-tensioned, tho.

    Locker Room Live Load

    What do you guys use for a locker room live load? It's ancillary to a gymnasium so I think 100 psf is overkill. Judging by my gyms locker room I'd go with 50 psf live + 20 psf partitions.
