# Cost to Jack & Bore

## Cost to Jack & Bore

(OP)
Hi, folks,
I'm working on a project in Hall County, Georgia, where I may need to tie into a sewer line on the opposite side of a state highway. Does anyone have any approximate per linear foot costs for jacking and boring or directional drilling? That, and any advice you might have on the preferred method, would be greatly appreciated. The distance covered would be approximately 60'.
Thanks!

### RE: Cost to Jack & Bore

It depends a lot on the soil conditions and presence of rock/cobbles. You mention sewer - is it a gravity line or force main? Gravity may be more expensive due to the straight grade required - if soil conditions and the methods used even allow for it. Mobilization can also be a big variable depending on how far the contractor has to travel - it looks like Hall Co is fairly rural, so you may not have a qualified contractor nearby.

For one point of reference on cost, we were recently quoted about $50k to bore two 8" casings about 40' long under a railroad for a couple of gravity sewer services in central Washington state. YMMV. # ### RE: Cost to Jack & Bore looking at Pinward's price it's$625/LF. If I escalate the price I found to 2019 it's about $520/LF for 8" pipe, without the add-ons in the footnote.$625 could be a good starting point. In graduate school I had to take a course in estimating & cost engineering; the professor worked in the piping industry. He said they used this formula for estimating based on economy of scale:

Known cost x ((proposed size/known size)^0.6) = estimated cost

Wow, that's discouraging. I had a piping contractor give me a price of $140 per linear foot. He said that's includes everything - mobilization, materials, equipment, and labor (not counting setting 2 manholes). That would work out. But$625 is probably a project killer. I guess I need to do more research.

### RE: Cost to Jack & Bore

I would be asking for more info from this piping contractor you got the estimate from. Do they do that work? If so, get a quote in writing. If he doesn't do that work, ask him to refer you to whoever he thinks will do it for that price, and see if they really will.

My guess is that his \$140/LF estimate would be for a much larger project. As has been alluded to, most of cost of your project will likely be mobilization, so much depends on whether there is someone nearby with the right equipment.

### RE: Cost to Jack & Bore

The same professor also said "when someone gives you an estimate, ask him what's in it". BTW, you never mentioned the pipe size or length?

About 30+ years ago, I worked on a project where the electrical sub chose to jack 4" steel conduit below city streets to avoid pavement removal, MPT, etc. The conduits were generally 30 to 50 feet. I don't know what we paid but generally a two man crew could bore one hole a day, then they bang the conduit through with a back hoe. They would dig jacking pits at each end and used a pneumatic machine that looked like a torpedo; it was about 5' long if my memory serves me..

### RE: Cost to Jack & Bore

I inspected a job where the sewer contractor augered holes from the mainline sewer trench to the right of way line for installation of 4 inch sewer laterals. they would auger a 10 - 20 foot long hole, install the pipe and move on to the next and a three man crew managed about 10 - 20 houses per day. but the trench was already dug, and they did hit a leach field which I am sure cost extra
