Steel building and bolt torque inspection

[ExWrench]

What are the torque spects, 4 or 7 ugga duggas?

Hmmm, pretty sure it only requires fou . . .

Any PE who specs out “snug tight” should be stripped of their license.

specs need to be a torque value range...and the inspection starts with calibrating the tool used to torque the hardware to that value.

. . . better make that seven ugga duggas

I'd ask him where it says that his method is approved by an engineer on the plans. You should get him to email that to you and send it to the building company and ask them if it's acceptable. Or just fire that company and hire one that's going to inspect it per the plans....

This^^^ It is the inspector's job to make sure that you are performing the work in accordance with the approved plans, not play engineer.

Yeah fuck those engineers for following code and trying to make sure that things are reasonable to construct. Anything less then individually checking every bolt by UT elongation should be banned, and anyone one who accepts torquing aught to be run off the jobsite and never be allowed to even look at a bolt again

Fucking do something about it. Geeze you guys and your whining about laws and taxes and government. Go join your local township board and try to roll back the laws and regulations. Start a movement and get people to join. But fuck no, make shitty comments and whine about it constantly. Bunch a virtue signaling going on here lately.
Don't get me wrong, i believe we should roll back most all traffic laws and get rid of many useless committees and programs too, but saying all laws and every bit of gov should go is not a starting point...

I have no building code where I live.
I was born in a county that had building codes, but I fixed that.
Your turn.

Section 900.01 of the Pine City, MN Code of Ordinances says you use the Minnesota State Building Code.

I finally reached the inspector today, he does not want turn of the nut, he called that a bullshit method.
He wants each bolt tight enough that there is no airgap between any of the mating surfaces, he said I will probably break a few bolts getting it there. Seemed like a reasonable guy, but I cant stand when the inspector wants something other than whats on the building plans.

On a side note my county has been growing pretty rapidly the last few years, they hired all new building officials who are retroactively enforcing the codes. They have made a few people pull permits for things that weren't permitted and bring them up to code. I know of atleast 1 building that they had to knock down because they werent able to bring it up to code. I live in a very red county but that doesnt matter, they want their money and control.

You have an inspector that just wants visually tight bolts.. that's awesome.. that's way better than having him go over everything and open cans of worms. Be happy you got a good one.

on rentals and septic systems
now do your best to find me a county in MN that doesn't inspect those two

I dont think they would be specifying "snug tight" if it called out for a325s. I guessing this is not a structural steel building and more likely light weight tube.


Are they also inspecting the anchors to the foundation?

They do all the time with a325 bolts. Sounds like a kit bldg, which is structural. Columns will be a325 and girts and channel will be 307 bolts. Either way, less and more lenient inspections is better for builder.

pine city is just the closest walmart
I'm about 8mi out, so pine county, not really pine city.

Fuck that. If you are snapping good a325 bolts then you are flat out over tightening them. How do you or the inspector know that when a guest of wind comes and further loads the building that bolts are not going to start breaking.

The inspectors job is to observe and report. Do it turn of the nut and mark the bolts. Let him observe and report.

well, you started something. I'll give you that. but you're too high in the chain at county level. townships,village and cities determine their building code requirements. country doesn't do shit in our area either..thank you for being a trustee on a board and starting something

The more I think about it the more pissed I am. I talked to the county today and this guy is basically the only inspector they will allow me to use. He is an older retired guy that knows everything from talking with him.
Im not sure where to go, I really dont want to ruffle feathers with the county, as I have 2 more buildings to put up on my property and dont want to piss them off.

A325
1/2" 50-58 ft lbs
5/8” 99-120 ft lbs

I guess being a mechanic with a digital torque wrench I don't see the issue?

Either I'm confused or your retarded... he just wants you to tighten the fucking bolts, it's not that hard. Rattle them down tight and be done

This x1k, if he was an engineer he wouldn't be doing a bolt inspection. Have him email you what he wants you to do, and send that to the city with your stamped plans and say you feel like the requirements he is making up do not meet the requirements of the licensed engineer who designed your building. It's important to email cocksucker's like this so you have a record of their bullshit.

Also, where do you live? There's got to be another private inspection outfit in your town or a nearby city. If I remember right bolt inspection is real low hanging fruit for a private inspector and only requires an 8 hour class here in Washington. Also, fuck that guy!

Mating surfaces are not flat on these buildings, they distort a bit when welding. Getting rid of the airgap is not possible at every single joint due to this. Ive tightened several of the 5/8 bolts to the point they start to strip without pulling the surfaces completely together.

 

[Bigwoolyd]

AISC definition of snug tight: The RCSC Specification defines a snug-tightened joint as a joint in which the bolts have been installed in accordance with Section 8.1. Note that no specific level of installed tension is required to achieve this condition, which is commonly attained after a few impacts of an impact wrench or the full effort of an ironworker with an ordinary spud wrench. The plies should be in firm contact, a condition that means the plies are solidly seated against each other, but not necessarily in continuous contact. There is no upper limit to the pretension that can be present in a snug-tightened joint. Twist-off-type tension-control bolts can be used in snug-tightened joints, even if the splined ends are severed during installation.

It's the engineers job to define the requirements. Don't over think this. The inspector should verify the specified size and grade of fasteners used match the drawing and the structural members are in close contact and the bolting is not loose.
Turn of the nut method is defined as snug tight plus an additional rotation that is a function of the bolt length. This appears to be overkill in your situation. and small bolt sizes.

ok so I'm the retarted one.. so paint me a picture here.. your problem is your clips are not flat to the pearlings when you tighten the bolts? Are the clips square in relation to the wideflange? Cant you just beat the gapped part of the clip after tightening?
