The Metwood product has a "code compliance report" from Intertek (never heard of them). The JoistRepair product does provide some calcs but I don't see where the connection of the plates to the joists were ever checked. What are y'all's thought on these?

I can confirm Intertek is a valid code complient research report, similar to an ESR report, but i've never seen these before.

Is there anyway to get the calcs they used to approve it?

Haven't used those specifically, but I've designed my own out of plywood, lots of nails, and a lot of glue. I'll DM you the detail.

Got it - thanks. Will keep that in my back pocket for future repairs.
This is my situation which is a bit different as moment needs to get transferred as well as shear.. I would prefer to spec an off-the-shelf product than doing the calcs.

I've spec'd the Metwood one before. Never saw the install, but no complaints since.

Don't they test them to get the approvals? This way you have actual performance data instead of just theoretical calculations.

I have never spec's this product before, but I did consider it once. It turned out that, in the case I was considering, the field conditions didn't meet the limitations of the product (e.g., more than one hole per joist, etc.). Otherwise, I would have certainly spec'd the product. I was satisfied with the engineering report. Section 7 of the engineering report states states that the supporting evidence for the evaluation includes tests, engineering analysis, and documentation of the manufacturing quality control process. I guess you just have to take Intertek's word for it as for that evidence.

They are tested. you'd probably have to reach out the manufacturer to confirm their test criteria, but the Intertek report i'd think would have all the required information to use just like the ESR's do.

I reached out to the manufacturer but they did not respond. I suppose if I am bored I can reach out to Intertek as I do not see it ion their report. I ended up just specifying them and calling it good.
