Thread: Holes in Joist too close to foundation, Inspection failed

My contractor has made large holes in joist to run ducts for bathroom, as part of basement finish.


Inspection failed as the holes were too close to foundation.

How can I get this fixed, who and how much this costs?

Any help is greatly appreciated.

I have no knowledge of these things

Thank you

Have the contractor contact the manufacturer of those I-Joists, the manufacturer can then provide an engineering letter or other documentation as to what repair is acceptable.

Sometimes, the only repair approved by the manufacturer of the I-Joists is to replace the I-Joists - but that hole may not be that bad, the manufacturer may have a repair for them.

Jerry beat me to it, but generally the manufacturer sets the rules for notching, cutting, and drilling holes. In general, the holes should not be more than 1/3 the depth of the joist and usually have a 2
inch margin from the top and bottom. From here it looks like the holes are too big and too close to the bottom of the joist, as you stated.
Like Jerry said, contact the manufacturer.

Sorry my link doesn't seem to work, just Google notching engineered joists.

I thought of another possible solution, but you would loose floor area, maybe gain a closet - install an additional load bearing wall (provided there is a footing below it) under those I-joists before those holes ... the part of those I-joists with the holes would no longer be carrying a load, they would just be there 'to hang the drywall ceiling from'.

Sure would beat 'replacement' if that ends up being the manufacturer's 'repair'.

According to TJI you can have as close as 2ft 6 inches from the bearing point. There are other reasons also why I feel this is not the bearing point but lets get the comments flying. 

Kevin,

Where did you find information on "476"?

All I came up with in my searches were load ratings with "476".

The number is not part of the information, the question, or the answer? Then ... why did you mention it?

I saw the number too, but did not find anything on the number, soooo why bother specifically pointing out "If you blow up the picture you will see numbers. 476 is on the joist."???

There 'may be' "a" bearing point behind that stud wall, however, "if" that stud wall is also "a" bearing point, you also go by that bearing point (the closest bearing reduces the span of the joist).

I was not sure where you were headed ... and now I am wondering if you were even headed anywhere?

I was thinking that you might be on the Right Trak.

thank you for all the replies, looks like most if not all are leading to getting in touch with the manufacturer. will be on it.
