    what are folks requiring as far as documentation on "foundation repairs". specifically, driven piers under existing foundations. I'm in a new job, new area, it (this type of foundation repair) is a totally new thing to me. i fully grasp the concept of piles driven, piers driven etc. does anyone ask for/require an initial grade report on the existing foundation to show where and how much support is required and at what location on the house? what about reports of compressive limits on the piers that are driven, and a final grade report to ensure that what is "being done" is actually being done?

    Do not believe that the IRC addresses this type of construction thus you need to look at the IBC. The IBC would require a geotechnical report (Chapter 18) and special inspection of the installation (Chapter 17). You should also expect engineering calculations for the repair. I believe that this should satisfy your concerns.

    We require engineering and documentation from the contractor. We perform an inspection after the piers are driven, prior to backfill. The inspection is mainly to verify the correct number of, and type of piers were used, per the approved plans.

    Any responsibility for soils and structural engineering is placed back on the contractor as a condition of permit.

    codeworks,

    In this area, there are companies operating under the guise of being foundation
    repair specialists. Their idea of repair and the code are quite different. As Mark K
    stated, some type of engineered plans ( or scope of work ) should be submitted
    for review by the AHJ. There should also be some type of competent inspection
    of the project and the finished product. Also in this AHJ, there are structural
    engineers who work for the same company performing the work. Hmmmm!

    Seems like a "conflict of interest" to me, but this AHJ allows it. I have inspected
    some of the work that the foundation repair companies ( here ) put in. I would
    question it all!

    If your AHJ wants a proper installation, then, IMO, there should be some type
    of engineered plans submittal, ...independent & thorough inspections of the
    project, ...a complete inspection report that is sealed & signed by a licensed
    and registered structural engineer, and not some "engineer for hire" working
    for / associated with the foundation companies. Also, there should be a
    documented "paper trail" of responsibility and accountability. If something
    is not done correctly, who is responsible. Both after the completion of the
    project and the years to come.

    Also, if you are in south Texas, aren't ya'll required to have high wind
    means of attachment & possibly high water tables to take in to consideration?

    Hope this helps! :)

    Just want to introduce myself. Kyle Cresson with PrimeFirst Inspection. I'm excited to FINALLY be given the time to focus on building out our new network of trusted contractors. I'm sure I will have a lot questions, but I will do my best to contribute as well.

    I look forward to being an active member of the community. So far this looks great!
