Re: PEMB engineers

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I try not to review the engineering or design of the PEMB whenever possible.  If I can sink 4 - 3/4" anchors into a hunk of concrete to resist 20k of uplift, my job is done.  By reviewing/approving and requesting additional data from the PEMB manufacturer on anything which occurs above the finished slab level, I may be unintentionally taking responsibility for the oversight of the building engineering.

Of course, I usually state explicitly that I am engineering only the foundation for reactions provided by the metal building manufacturer. In cases where there is an architect involved, I expand that to specifying the performance criteria (environmental loads and deflection limits).  That thing they set on my foundation may be a hot air balloon, a giant wooden pallet, a group of containers, or a PEMB. As long as it matches the interface loads and bolt pattern, it's none of my business.

I may be off base, but that's how I understand my E&O coverage.

That is the way I resolve base plate size and thickness issues also.  I have a project on my desk with 20k uplift 3/4" bolts @ 4"oc and 1/4" thk base plate.  I give the design engineer the choice.
Provide engineering to justify base plate thickness or change to what I am directing you.
If not done shop drawings are rejected as unacceptable. The cities/counties have no problem with this.
And I also tell the client if he insist we design with preliminary numbers he will pay cost for redesign when final calculations are received.

Florida Engineering Law requires that the delegated engineer design the PEMB to match the written directives received from the EOR. You may be wasting your time trying to sort out the problem with the Contractor or the Architect. You need to talk to the engineer whose name is printed on the PEMB drawings. Once the delegated engineer realizes that their license is in jeopardy and decides to follow the rules you will have an ally at both ends of the problem.

I guess make mandatory requirements like the GC shall supply a full set of our drawings to the PEMB mfr for review and coordination, and put a minimum spacing that WE REQUIRE. But what else can we do? I read some articles in Structure and MSC on this very issue, and half of them I laugh, the other half I cry..... 


Am I ignorant to assume someone is reading our drawings besides me, until it is way too late??....  :-----(
