    Stamping plans for welded Ibeam building?

    Ron, the guys that are welding these are indeed welding pros with plenty of credentials. As for the purlin attachments, they do weld them to the beam flange, but also add a 6" triangle clip. Just because I have the time right now, I am running some math on the building and I think we can...

    Stamping plans for welded Ibeam building?

    Ron, lol, how right you are engineering comes before building..... Unless you are a backyard bandit. Then you build it on a guess, and make claims about how overbuilt it is.... Regarding the building, 60x100x18, 2:12 pitch, 25ft bays, 15# snow, 20# live, 112 wind ASCE-7. We have plenty of...

    Stamping plans for welded Ibeam building?

    What we are ultimately faced with is a documented, certified welding team that simply does not fully understand structure design. They appear to work off other sealed plans and "rule of thumb". If we go this route, we would ultimately spec all materials, welds, etc, but have some comfort in...

    Stamping plans for welded Ibeam building?

    When I mentioned the steel vendor, they are a separate entity. Only a building material and steel supply house. We've actually bought from them in the past. As for the builder, yes, I mentioned that I may just let him put together a proposal, then evaluate the design to see if it even holds...

    Stamping plans for welded Ibeam building?

    Agreed! The vendor of the steel is a large and reputable company. I think the way we might approach this is evaluate plans as the builder wishes to build it and run load calcs against it to refine and validate it. Probably adding some required structural improvement elements. I do notice...

    Stamping plans for welded Ibeam building?

    Thanks. If we go this route, we would end up being the engineer of record. However, though we can run load calcs, there are many different ways to build such a building and we have no experience in such animals. I guess we might want to sniff around for any sealed plans for comparable...

    Stamping plans for welded Ibeam building?

    We are looking to construct a building for ourselves and was leaning towards a PEMB building but delays from manufacturers are creating some issues. We are in talks with a company that basically uses off-the-shelf beams, cut and weld onsite. I'm simply baffled how they do this with no...

    Optimizing insulation methods in PEMB building.

    LOL, you nailed it with FEMA! Regarding building science, yes, I have honestly wanted to have that conversation with someone that truly understands this challenge. Correct about the whole vapor/air barrier deal. I really do NOT want a vapor seal on the top side, I just want a better air...

    Optimizing insulation methods in PEMB building.

    We are working on designs of a couple buildings, mostly used for manufacturing so mostly no interior finishes other than the insulation facing. What is common is the "super saver" method, which is decent, but I am questioning the need and extra expense of the poly liner as opposed to just...

    PEMB buildings from China? Engineering?

    AND to make this more interesting, it appears the pricing is going to be comparable, or even more expensive. IE, at least with that company, zero reason or incentive to even consider such a building with all the potential engineering questions.

    PEMB buildings from China? Engineering?

    I would be curious how that is purchased and evaluated? Do you get foreign calcs? Are these Chinese or something more substantial like German? I think it's one thing when bringing in a high quality item. Quite another knowing full well a foreign purchase is a cost cutting tactic. As I...

    PEMB buildings from China? Engineering?

    Oh you 100% nailed that! Dime a dozen of the people that say "we just need this stamped", like "oh, no biggy, here ya go, I now own a lifetime of risk". Years back we were looking to use some steel fabricated roof trusses. Says "engineered" right on them...lmao. We ended up modeling them to...

    PEMB buildings from China? Engineering?

    I would say that is why I am here asking. Trying to better understand how common this is, if at all.

    PEMB buildings from China? Engineering?

    We are working on a couple projects with PEMB buildings. We primarily have only done the engineered footing work for such buildings on the past. A guy in the office reached out to a building supplier to find out they drop ship the building kit right from China? I am now very curious if this...

    IFC IBC fire codes and occupancy.

    I wasn't certain which section to put this but we are assisting in design and construction of a multi use building in a rural area. The building size is 15,000sf, prefab steel building, free span single story, 20' tall. Because of the rural area and desire from owners, avoiding a sprinkler...
