tyraps as emt support

Guess what I saw today???

Guess what I saw today???

I was inspecting a job today, and I saw this installation...talk about timing!!:grin:

Pierre, what's that box (with the blue cable hanging over) below the big pull-box in the bottom picture?
And where are the bar joists?

I thought this thread was

I thought this thread was

a typical ground up installing, 14 NM pulling, wire nut taping, recepticle taping, back stabbing, ty wrapping but I glad to see I was wrong. I try to think of the code as a living document that with the input of manufacturers, electricians, engineers, inspectors, fire safety personnel makes us safer tomorrow than we are today.

Hey Pierre, I didn't see any red tag in the pics.

I took a picture of this with the 'red tag' in the picture, but it was so bright that the picture did not come out well enough to post. :grin: :grin:

Very interesting collection of stock.


We have

1. Tie wraps
   
2. Caddy Screw-gun box brackets
   
3. NEMA 1 metal cans
   
4. RNC
   
5. and Meyers hubs????

Someone must have needed a couple more inches on the right hand pair or they were trying to conceal the PVC from anyone looking at the installation from the box side.

Perhaps we have a classic example of "Use what's left in the trailer."

I would assume it is kind of what peter said..looks like they were short and need to extend the fittings..it is kind of a nice collection of electrical equipment..

 

[cschmid]

so pierre are you saying that the RNC cannot be supported by tye raps..

Actually I said that. :grin:

It is my understanding that bar joists are designed to withstand the forces applied to them in certain ways.

Such as the bottom chord of the joist is not to have additional loads supported by them (such as A/C units, raceways, etc...), unless they have been designed specifically for that purpose.

While I'm not a structural engineer, I do know a little about how bar-joist roofing systems are designed. Typically these systems are designed to live load/dead load requirements for the area, which is mostly determined by weather for such things as snow loading and wind lift. It is my understanding the dead load requirement is moderately higher than the weight of the roofing system itself, allowing moderate and distributed weight to be added to the roofing system wth no adverse effect. Substantial and/or concentrated loads are a different matter :wink:

As to major differences in attaching light to moderate loads bottom chord vs top chord of your standard run of the mill bar joist is pure poppycock.

Some areas I work in will not allow support of anything from the bottom cord.

From a structural standpoint it may be poppycock but you gotta play by the rules or it can cost you.

All too true!

I am going back to this site on Tuesday or Wedsnesday...there were fire rated walls that had box penetrations they have to remediate.
I will ask about the meyers hubs. I did ask the forman during this inspection, he just shook his head...maybe an apprentice did this, I will see if I can find out. This forman is a very bright guy, he has his head in the book a lot and asks more questions than you guys do. :wink:

Yes, I did accept the ty wrapped support for PVC.

This job has some other interest electrical stuff going on that I have not seen. If the pictures come out good, I will post some.
(On this job site I have already taken more than 1000 pics over the last 2 years ...good stuff! - there is a double 4000A 480v service on this property)


In more than 2 years of inspections here, I have not written one violation...we have a very good working relationship here...we discuss the job just about weekly.

That is a heack of a structure if it is 2 years in the building..may I ask what the final product is...

 

[Pierre C Belarge]

It is a large multi-building hotel and property.

The owner went through 3 GCs, keeping only the same electrician through the whole process.

Lots of cool stuff for a hotel... many, many changes.

This portion is for a 3000 person ballroom and ancilliary spaces around that room.

 

[cschmid]

nice sized gathering space..I would assume he is having a budget problem..

Being close to the job, I thought the same.
It would seem though they must have a bottomless pit with the funds. They just keep adding to the job. You should see the different fireplaces they built.
I am very interested in seeing the final build of this ball room, they are sparing no expense...hence my very expensive inspections, which most likely will be about .001% of the total budget.:wink:

 

[cschmid]

must not be enough smoozing by the gc's then..

Meant to resond sooner just been working alot. 7 year Ive been doin this as a worker not a boss. But my boss would not allow cable ties to support conduit cause basically hes not cheap even if the customer is they can find a cobbler. We make our money on our quality work not our corner cutting "code allows it". Ive never seen a cable tie hold a pipe from sliding. Also they can easily be snapped. Hes been in business like 27 years so he must be doing something right.
