There we go, that changes things. Looking in the NDS a 5/8 lag in withdrawal in wood of .46 SG is 395 lbs per inch of penetration, he's calling out 5" and 4 lags although I'd want the tight 2 able to take the load. I'd also call that the span of the arched member in your check. There's also now a midpoint load on the 6x8 if you're still unwrapping it.

That's section 11 of the NDS and worth a read for properly making those connections. awc.org, hit the publications tab I believe.

looks like we are good on the lags. 1450 pounds on each. at 5 inches that should support about 1975 pounds each.

we also will have lags into the purlin/corbel at the 10' span location as well. In general I think we will just want to make sure this is all as tight as of a conneciton as possible and everything is snug together.

The rafters look fine.

He also mentioned if we want to increase the size of the plate on top of the steel post to support the horizontal 8x18s rather than the simpson hanger he would be fine with us doing that for extra support.

alright so what we settled on was:

CCT column cap from Simpson Welded to top of the steel column

Glulam 6-3/4 x 15s instead of the 8 x 18. prices were out of hand for the x18s and we had splitting concerns.

we got the columns fabricated, with welded buckets, and they were just delivered.

For the arch beam, we decided the min thickness will be 8.5 inches instead of 5.0.

For perspective on our house / project space, here are a couple shots i took from outside and inside the house. We just poured the first footings and ordered the timber

Excited to finally get going!
