I got this from our engineer. About commercial construction and ground up buildings.
"Yes, 8-9 weeks currently on drawings.(light gauge metal stud structural) I had one that had to go to another design firm down in Atlanta that is 6 weeks out, but their price was triple mine and they are Dietrich affiliated, so material is heavy as well.
(Bar joist availability) Basically, there are no bar joists this year if you haven’t already gotten the order in. I am having to redesign a DOD project that I am EOR on, because even the US Gov’t can’t get a spot on the production schedule. One joist manufacturer said they will resume taking orders in Jan-Feb of 2022, the other says they may be able to deliver in late Q1 of 2022 of orders taken now. Basically an 8 month wait no matter what. Structural steel is falling farther behind as well, last I checked it is about 12 weeks for drawings, and several more weeks for material delivery, but the full transition away from joist has not been figured in yet. There is just a lot going on, material prices are up, and there are supply chain breakdowns across the board. I know some GC’s are trying to take the stick your head in the sand and pretend like it isn’t the case, but basically if you are going to permit now, you are not building this summer, it doesn’t matter what the material is. Light gauge is the shortest lead time, but even if you go with supplier affiliated design, you are still 7-8 weeks from approved drawings, because a lot of engineering firms are changing their allow 7 days for review to 21 days to account for the design overload. That puts you optimistically in August delivery for something coming in right now no matter what, and there are a lot of projects out there thinking they are going to be getting materials in June-July, but that opportunity is basically gone. Nobody is staffing up for the increased demand either, because by the time you would build production facility, or add staffing, the demand, heavily fueled by a $6 trillion dollar shot in the arm is going to die off. Still this is a much better problem, than the nothing to do that would have likely been going on without the stimulus. So just buckle down and be patient."
