    Default Holes In Webs of TJIs

    On today's inspection a couple of TJIs had holes in their webs that are somewhat suspect. Your opinions please.

    The hole in the web of the header is near the end of the TJI. Is the hole too close to the joist hanger?

    Don't know what happened but someone went crazy drilling holes in the web of the TJI near the exterior wall. I suspect the holes were intended for running the gas line but the plumber eventually decided to run the gas line under the TJI.

    Thanks in advance for your input.

    Bruce,

    Looking a bit old there. Might think about retiring?

    Yes, the hole immediately adjacent to the pipe looks too close to the end. Not sure whether the random holes are problematic. Typically, TJIs come with pre-stamped holes for this type of use. The installation instructions are available online. You might want to download them.

    I think you've got a mess there for sure. The hangers look to be missing fasteners and a single TJI is used as a girder... likely all wrong.

    Also, to expand on what Gunnar said, the intended holes are left in place and the butcher just free lanced it.... further questioning his ability.

    edit: In that middle picture is the lower chord bearing on the top lip of the lower chord for another TJI? and/or is the one being beared on a TJI with it's upper chord ripped off?

    Over the years pretty much every questionable install I've suspected and looked up on TJIs is wrong. The rules are very specific. Bubba doesn't usually read the rules

    Sorry, the photo is not clear but the TJI is supported by a 2X that is on the top flange of a steel beam.

    Apparently neither does Jose.

    Yeah, things have been tough lately. I guess it has taken a toll on my youthful appearance.

    I wonder if the series of holes was drilled to be able to get a wrench on the gas line? From the "What were they thinking" file for sure.

    I think you may have hit the nail on the head. Thanks for that insight.

    If the original guy comes back to fix it...he might think you did his job for him with "that reinforcement tape" you installed

    Some of them should be promoted to the "They weren't thinking" file.

    As I recall, the last engineering I saw on those holes were bored holes (i.e., "wound" holes) and that the holes had to be twice their diameter apart, I have forgotten the maximum size, but that varied with truss depth, and the twice their diameter apart also applied to the distance from the ends as I recall.

    That long series of holes ... someone really screwed that TJ up doing that.

    Irregardless of why the holes are there. A truss is a truss weather it be floor or roof it is an engineered design and may not be altered without prior approval of the design professional. It would be prudent to request a raised seal letter from the designer of record acknowledging that the original design has been altered and that the existing conditions are acceptable

    That first photo suggests the configuration was designed for the PVC. The short bits might not carry enough load for it to be a problem, especially since the nearest one is intact. The main issue I see is the far middle TJ being supported by the cross piece with the hole near the end, rather than the "holy" piece itself (depending on what's overhead). And of course the one with a zillion connected holes in it!
