Directional drilling will cost from $15-$25/ft.
Plowing about $4 - $6/ft
Excavation $8 –$15/ft
Blowing $.50 - $1/ft
Splicing $10-$20 per burn

I've been asking around for companies to do a bunch of build up here. I haven't
liked most of the quotes I've seen. I'll let you know what I end up doing.
That said, I was probably going to do everything other than the dirt work
myself.

In illinois, who would be a project contractor to approach for a legitimate
quote on a fiber project like this? Start to finish, permitting, product spec,
duct, fiber, terminations, handhole/vaults, trench/bore, etc

oh. I cant see that if we ever did this type of fiber we would direct bury.
aside from cost is there any reason one wouldnt duct?

300k was a quote at one point. Weve got a little under half that in

30k / mile is pretty typical.
"You can cut and splice duct when going over and under obstacles. If
doing direct burial you would be doing giant figure 8s or cutting and splicing
every time you hit a culvert or other shallow facility."
I assume these figure8 are slack and in handhole/vaults? so in rural
areas, at least 1 per mile since theres a road every mile?
Nope. The figure-8 is how you have to handle the cable when
installing it if you don’t have duct. When direct burying the cable you have
to take the spool with you as you go since you can’t pull cable once it’s
buried. Every time you need to pass under an obstacle you either have to cut
the fiber and splice it back together or pull the entire remainder of the cable
off the real, store it temporarily, shove the end under the obstacle and then
reel up all the cable again. It’s a seriously labor intensive process and you
risk damaging the cable every time you do it.
Whats the rule of thumb on slack? is there a percentage? like say for
every 1000 feet you have x feet of slack? I aasume when an auger hits the duct
it will pull alot of that slack?
10%

You can blow another fiber over the top of an existing fiber.
Fewer fiber cuts and splices etc. In my opinion you don’t save
that much money with direct burial.

I know we've had this discussion before.... we don't have gophers
in Michigan. Only damage we have had on direct bury was due to gas company.
Yeah it was a pain to fix, about 8 hours of downtime. But the cost savings is
worth it to me for my network. We are doing FTTH so we do have more handholes
for test points. Usually at least 6 per mile. Don't know where Steve is or how
well funded so just sharing a lower cost option, I guess.

The worst part of direct burial is gopher damage. And they will

strands intact or just break one or two of them.
Yes, you first have to find the damage and in long rural
stretches that can be difficult, more so with direct because you have to dig,
cut, test, dig cut test. With duct you just pull on it and see if it moves.
OTDRs are not precision measuring devices. Even if they are +-1% accurate,
that is 52 feet of uncertainty in a mile. So you shoot both ends and then
extrapolate the center of overlap or gap.
Pray, dig, cut, test, splice, pray, dig, cuts, test, splice.
Repeat until you get there. After some time you will have it bracketed and
many times you just replace 1000’ instead of actually finding and fixing the
problem.
All the while customers are very unhappy. I have had it take a
week to fix very long remote troubles like this.

We also usually install a second duct on all major routes.
Chuck, with your long career, I assume that you've had a few
cases where direct burial took a long time/difficulties to fix?
Now working in the long-distance/underground industry, doing all
the planning and permitting, I've seen our guys pull up things - including a
boulder the size of a car - from the ground so that they could get that conduit
through.

I never do direct burial any more. Not even on drops.
Generally I install an extra duct, I like duralines future path products if I
can justify the expense. I need to learn how to install microduct into regular
duct. I am sure I can pull it but I would like to figure out how to blow it.

I try hard to steer clear of direct-burying cable, which is
much easier to damage and extremely time-consuming to repair, unless it's a
non-crucial line (e.g. standard residential customer, although those we
currently put in conduit as well, to keep future risk and repair costs low).
If this customer is paying 1/4 million to get a line installed,
it's probably crucial. One day when that line gets hit, if it's in conduit it's
likely possible to get it repaired within hours to a day. I've even heard of
cases of the fiber surviving a conduit-line hit since it's "loose" inside the
conduit and has slack at the ends. If a direct-buried line gets hit, especially
next to a road etc, it may be needed to get locates, arrange a drill,
electrical/gas line safety watch, etc, possibly even arrange more permitting
for a new vault, which will often move time to repair to days or a week+.

Steve in our area we could do that "on the cheap" with 12 or
24 count cable direct buried for around 100k. There are so many variables
though. You really need someone who has done work in that area and is familiar
with permitting costs and requirements. I'd it's so rural that you can plow the
bulk of it and you are OK with direct bury you can save a ton of money vs
putting it all in duct.
Personally I run at least 24 strands on any run that's going
"somewhere". Dead end runs can be 12F.

If a guy wanted to get fiber in the ground, non aerial

I would guess that duct is the best thing to put it in,
innerduct being better.
I'd guess 96+ count isn't going to cost any more per strand
to put in the duct than 2 (not the cost of the fiber itself)
Lots of dark strands and duct space is probably lucrative
to have just in case.
Slack, handholes, vaults, etc, what would you put in there?
10 or so customers on the path so not a ftth type thing.
