Cost to run feeder

Can anyone tell me a ballpart # to run (3) sets of 4#600KCM, 4" PVC conduit for 100 linear feet underground?
I am thinking 60K, allowing $200 per linear feet of of 4#600 KCM feeder run... so, 3 sets x $200 per feet x 100 feet = $60,000...

600 kcm copper is about $20/foot.

So about $250 per foot for the wire, or a total of maybe $25,000 for the wire.

What are you planing to do for the ground conductor? Will need to be a full sized ground wire in each conduit.

2/0 ground X 300 feet is about $5/foot so another $1500.

4#600 plus ground will take probably a 5 inch PVC conduit so add 500 feet of that. Maybe $20/foot, so $10,000.

Trenching and filling is probably about $100 a foot by the time you get done with it. Maybe $10,000 contracted out.

So close to $50,000 in parts and trenching not counting your labor and markup.

Just my guess.

Thanks, no ground wire, forgot to mention, this is service feeder, no ground wire.

If you have 100 feet of pipe underground, why are you figuring only 100-ft runs of wire?

You gonna terminate right at the end of the pipe?

Don't you need at least 5 feet on each end to turn up and terminate?

$25,300 in materials, 64/hrs labor.

(3)x 4" PVC @ 100'/ea, 15' addt'l length on each conductor, (2)x elbows per run.

600mcm is $16.16/ft right now.


I would be in the neighborhood of $48k-$50k out the door.
 
The savings in wire cost should more than pay for increased conduit size, or even conduit quantity.
Have not asked the client yet, good point, if use AL, will conduit quantity increase? Will this save anything?
4 sets of 500 AL in 3" will be the same ampacity as the three sets of 600 CU. 500 XHHW AL is 2.40/ft. So 24k vs 5k for wire. I know what I would use......
