Typical framing species used in the Phoenix area circa 1985?

Typical framing species used in the Phoenix area circa 1985?

(OP)
Hi Guys,
Doing some analysis for an internal client on a one-family house they are working on in the great southwest. They're replacing the roof with a concrete composite and we are verifying the integrity for the added load.

We have a good set of drawings which appear to be from 1985-1987. The house is engineered very tight and unfortunately the structural notes are sparse.

What could I expect was used as typical framing lumber in that area, in that timeframe?
Thanks

RE: Typical framing species used in the Phoenix area circa 1985?

Probably DF-L #2 for 2x and 4x beams and headers, DF-L #1 for any 6x lumber.

If DF-L was spec'd for studs, the framer probably used Hem-Fir instead. Stud Grade for 2x4 up to 8'-1"; #2 for taller than 8'-1". Stud Grade for 2x6 up to 10'-1", #2 for taller than 10'-1".

Thanks. I assume that is inland DFL and not Coastal/DFL (North)?

Also, someone from our office seems to have borrowed our '86 NDS. You wouldn't happen to have Fb on hand for old-growth?

Personally, to be conservative, unless you specifically know that it is DF, I would assume HF values for all the framing members.

I have no idea what it is (or could be) and what's common out there. I'm situated in NY, and everything out here -- old and new -- is DFL / DFL(N). Wasn't sure if this was HF, I also wondered if it could be some Western species.

RE: Typical framing species used in the Phoenix area circa 1985?

If the plan was engineered, it was probably DF-L (not North).
If the plan wasn't engineered, it could even had been Western White Woods, then you would probably see everything overstressed with your remodel.

Or doug fir south which, I believe, came out of New Mexico.....
