Labor to run emt.

[SmithBuilt]

How long does it take to run say 100' of 3/4" emt in hours? No wire just boxes and emt.

Does anyone use a sliding scale. ex. If you had a small job of 50' to run . The time in labor would be more than 100' run.

Or if the run is much longer less time involved. I'm using 8 hours per 100' for estimates now, but I'm starting to think that is too much time on a large job.

I was always told to estimate the time I thought it would take ME to do the work and double it. Bunch of slackers!:smile:

I honestly can see some taking that long, but most I would say 6 hrs for 100'.

 

[iwire]

Under what conditions?

I am doing a fire alarm at a new Lowe's and the good guys are doing better then 1,200 feet in 8 hours with boxes etc. out in trusses on the open sales floor.

On the other hand, the work in the offices, and bathrooms is all ladder work, with a lot of bending and thought. 200'-300' per 8 hours in those areas was what I was seeing.

Under what conditions?

11' concrete ceiling, metal stud walls in place for office.

That's impressive. Did you bid it at that rate?

As Barbeer stated if I were on the job that might be close.

We have not run a lot of emt. 6 hours might be enough.

If you only have one guy working and 3 or 4 guys standing around watching him then that would be about right.

A man should be able to run a least 200 ft. in 8 hours even if he has to core drill the whole distance. (Just Joking ). I'm starting to sound like the people I used to work for.

 

[iwire]

That's impressive. Did you bid it at that rate?

Sorry, I am just a Foreman I do not know how it was bid. I do know the total hours they say the job has and we are looking real good on meeting that.

Thanks for the compliment but there is almost no bending involved out on the sales floor, a 90, a kick but nothing that has to be precise at 20'-25' AFF. Keep the guys supplied with a variety of caddy clips, cordless sawzals and lifts large enough to really work off of and it can go fast.

If you don't run a lot of EMT I can give a couple of tips.

First and foremost.....HAVE PLENTY OF EVERYTHING ON HAND. nothing slows things down then being short on fittings or supports. Have supports on hand that you don't even plan on using. If your planing on using 1 hole clips still have minnis on hand.

Sometimes I over buy and simply return the leftovers but really the cost of 3/4" EMT fittings is small compared to the cost of guys leaning on a bender talking about the stock they don't have.

Second....PLAN...Dont just start running pipe without a clear (or at least fairly clear) picture in your head or if large enough job do it on paper of how it will all come together.

In my opinion nothing shows poor planing more then a lot of crossing raceways.

Don't stuff the raceways, the time that will cost you when pulling and terminating can easily surpass the cost of leaving room to begin with....besides when things get added you may have saved yourself a lot of work.

Bob's tips on planning and prep work are on target, also Under what conditions? will be a big factor in time.

 

[Cow]

Just to add to Bob's list:

Prep everything as much as possible, put connectors in your 4 sq's, get the toggles installed in the boxes(if your hanging them that way).

I like to put couplings on one end of the pipe before I take it up into the ceiling. Reminds me, I'd really like to try one of those pipe hangers that hold all your conduit off the side of your scissor lift. Looks handy!

 

[SmithBuilt]

I have learned my lesson on having enough on hand. Now I go overboard I have too much stock that we carry around. With the price of things I will have to start returning things.

I still have a lot to learn about planning. The engineer has drawn 40- 3/4"emt runs on this job. It's going to take some real planning, and I'm slow at it.

I learned a hard lesson on stuffing raceways.

Thanks for the info. Even with all this info it's still hard to estimate varying conditions. I'm going to cover myself and forget I even bid it till they call. If they call.

5-6 hrs max. should be able to do it in 4.5.

 

[macmikeman]

Like they said, conditions, conditions. I do alot of work in occupied offices. Running emt above ceilings where there are stuffed cubicles below, desks, chairs, file cabinets, boxes of junk, and of course people working in the way, etc. That is where the bending is me, cause I got to reach way over something cause I can't get the ladder in any closer. On those type of jobs - 8 hrs for a hundred foot run with wire run inside of it, and setup,breakdown, and cleanup, might not be too far off.

 

[emahler]

brant..it that with set screw, compression or welded couplings?

 

[HighWirey]

NECA allows:

3/4 EMT, 5.0, 6.2 and 7.5 hours per hundred.
4" square boxes, 30, 35 and 40 hours per hundred.
4" square covers, 8, 9 and 10 hours per hundred.
NECAs figures were always a little heavy.

The 3 figures are Normal, Difficult and Very Difficult.

You did not ask about the couplings, connectors or fasteners . . .

Iwire is doing very well working at 20+ feet AFF.

Best Wishes

Labor units for estimating take this into consideration and use an average. Its when your labor does not make the averages that you start taking a hard look at he conditions and your labor, for a reason that your expected productivity is not where is should be.

On office fit up's with cubes and ceilings full of existing poor runs, the production times will increase, way up there.

 

[SmithBuilt]

Steve where did you get those figures?
I can see how they would be helpful for other tasks.

You did not ask about the couplings, connectors or fasteners . . .

Compression fittings, shoot in anchors (all concrete), all thread, and minis. Or strut for part of the runs.

Two men 130' , one saddle, 3- 90 , 4 boxs, nice off-set coming out LP , working off two 10 foot ladders. About 3 hours that includes getting everything to the second floor.

Smurf Pipe It!!!

I am doing a fire alarm at a new Lowe's and the good guys are doing better then 1,200 feet in 8 hours with boxes etc. out in trusses on the open sales floor.

Just curious, is the fire alarm required to be in EMT by local code or Lowe's spec? I have seen numerous Lowes that were wired with red low-voltage cable for the fire alarm in free air, so I'm curious why you have to run EMT.

 

[iwire]

so I'm curious why you have to run EMT.

They told me to.

The entire job is pipe other then re-loc for the lighting fixtures.

It appears to be a Lowe's choice, security in pipe as well.
