My spec'd rim joist are lsl, plywood engineered. Very heavy and called for 1 1/4" since small house. I'm thinking now that the word "joist" in rim joist may be the answer lol. The lsl is very heavy so I think I'm good in using. I may go ahead and use i joist at next open spot apprx 5 " oc from rim joist. Probable will block it out to rim as extra assurance.
Mingledtrash - so my question is the rim joist serving as the "end" joist. What your saying makes sense . The rim joist is structural as or more supportive in compression than the i joist based on your statement so I'm going with it. Thanks!
Keep in mind that you have some wiggle room in factoring in the placement of the I Trusses. Some go 24", some stick to the 16". Because you have to place the vent stack, drain for the tub, toilet, you have to place two trusses at that point, along with how you are running the other mechanicals.
Taking the time to do your homework and getting your notes on paper, before you commit, is a whole lot easier, then having to go back and destroy a group of trusses, because someone forgot what is going to happen at that point.
As OCD as I am on some things like this. I would go along with a Grease Pencil after you lay down the Pressure Treated Sill Plate on top of the Copper or other piece you are using as a critter barrier for Termites and Carpenter ants. Go along and mark out where the rooms are with a line, make a mark where electrical and other items, so that you have to not keep pulling out the paper, or you could also put the info on a piece of paper inside a plastic bag in your hat.
You will feel those trusses and other wood products by the end of the days, if you are not compensating for your muscles burning off the same type of chemicals that we get from working out and certain drugs. You want to not overdo it either.
The place across the street from me, had two guys framing and hoisting up the walls, pulling up the roof box trusses and lifting the boards for the roof.
It probably took them about 4 months with three guys on the job, because the owner of the place wants it to last as long as the old concrete place next door. That new building is not going anywhere.
