    If it's a 12' open space, then yes. But it looks like about 6' based on the proportions in the photo. And around here I see quite a...

    Then you're doing better than me. But if there's piles, I don't budge. If you want me to design a house on piles of any kind you'll...

    It doesn't take much movement to cause a crack like that. Best bet is probably to replace the drywall in that area. A patch will just...

    Ledgers are common place. Use heavy duty structural screws rather than nails, and hang the joists from them. Cutting into the...

    I'm with XR on that. Though I wouldn't remove that wall without careful verification. And while it was likely intended to clear span...

    phamENG replied to the thread I-Joist Rafter Connection.
    It's either $20/hanger, or that much and more on a specialized insulation scheme that would fit in a 2x12 and meet the...

    If the steel has yielded, then more load will result in more deflection and higher concrete compressive stress, but the steel will not...

    phamENG replied to the thread Contractor Stealing My Plans.
    Tough luck for him, then. I've only seen this happen once "in real life." It was resolved before it got to court. While the...
