When I was looking at the meter pits made from culvert pipe, one of the
manufacturers had instructions saying to add a concrete collar around
the pipe to make it traffic rated. They had an elevation view which
appeared to show just a concrete ring around the culvert pipe. They
didn't *sell* a concrete ring, so I wondered if you're just supposed to
pour it. Maybe put in two concentric pipes and pour between them? That
ought to be strong enough to park a truck on.
I'm not saying legs are a bad idea....maybe saves horsing around with
concrete.

Yes, some kind of tab to keep it centered. Perhaps some legs that
would go down the inside of the culvert with some small plates on the
end for feet to give it some more crush strength.
The legs would not have to be attached to the lid.
Not sure whether to make a hinged lid or keep it simple and cheap.

Some sort of studs on the bottom to position it on the pipe, perhaps?

Yeah actually I just realized that 18" diameter is kind of tight for a
coil of OSP fiber. Do-able, but tight.
I guess the hunt continues. If you do make something, let us know.

I don’t want to do one that small. But this is ideal for a smaller
handhole. I really can’t add much value. Too bad they don’t do a
larger one.

Chuck,
The Hancor meter pit doesn't include a lid. Turns out it's just a
pre-cut piece of culvert pipe.
The meter pit lids I'm finding tend to be cast iron. They're heavy
and costs hundreds of dollars.
Not many plastic options, but I did find this polypropylene unit.
List price is $92. Gives you an 11" dia opening into an 18" pipe.
They also say 'water meter' on them. Maybe I'd have to grind that
off.
If I add $30 for a 2' chunk of 18" culvert pipe I'm at $122 list.
Hypothetically speaking, what could your hypothetical product do for
me better than this one?
Asking because I'm interested, not trying to be snarky or anything.

Like this: http://www.hancor.com/product/meterpits.html
Seems like water meter pits might be a much cheaper option for light
duty:

Baltimore City is in the process of replacing all of its water
meters. For some of them, this involves replacing the "vault" they
are in as well. There is a construction lot near my house where
they store them and they look a lot like double wall corrugated
pipe with U cutouts in the bottom but are clearly manufactured.
Guessing they would be a whole lot cheaper then real vaults. Not
sure how they would work in a greenway as the covers are usiualy
set in concrete.

This is the spec you're looking for. Note that they certify the
complete assembly so something based on drainpioe may not really
pass the spec. But we would atill be interested. We just had to
replace a plastic handhole last week cause a tractor or something
drove over it. Something strong but cheaper than a $200 polymer
concrete handhole would be ideal. We don't have to prove
compliance to a certian spec in our area.

I am thinking that if I put in some legs that would fit inside
the culvert and if the lid was about 6” wider than the culvert
all the way round, both the lip and the legs would be pretty
strong if someone drove over it.
I need some my self. Sounds like a worthy project to resurrect.
Have to look up the method for rating hand holes. Something
about tire widths and forces. I know with the polymer concrete
you elevate the lid and drive a truck of certain weight on it and
it cannot break. Not sure where I found that reference. I think
it was some kind of DOT document.

We would be interested in a 24" version.

36" diameter? That's a big honkin handhole. What are you guys
putting into these hand holes?

I was making handhole components a few years ago. Not a big
money maker. But handholes are simply too expensive. I came
up with some alternate designs, like a slice of 36” plastic
conduit. Made a lid to go over it. Maybe I ought to revisit
that project. The world needs lower cost hand holes.

We're looking at doing a neighborhood where we have wireless
now. Private association of about 40 homes. The president is
also an electrical contractor and has helped us on other
non-fiber stuff in the past. So at least we can get duct at his
cost. Looking like about 6250 feet of duct and 21 or 22
handholes. Probably going to follow Chuck Hogg's strategy with
1x4 PLCs in the splice cases fed by PLCs at the cabinet. My
rough guestimates are around $25-27k before putting it in the
ground or customer drops. We figure we can make a business case
with a $1k install.

Drops were anywhere from 150' to 1600'. The long ones
naturally pushed up the average quite a bit.
On the feed down the road it's $1.80/foot plus the cable.
The contractor is supplying all material except the cable
itself and honestlyI don't recall how much of that was labor
vs material. We did have to add 4 poles, so there's that in
the $17,000/mile. And that also includes splice enclosures,
switches, optics, switch enclosure, and electric installation
at the switch enclosure.
Does your $1/ft in materials include the actual fiber? If
not, then we're very close. If it does then I have to
sharpen the pencil quite a bit.

How long are the drops? Labor for main runs cost me about
$.75/ft last time I did it, plus around $1/ft in materials.
I didn't have to do much make ready though, that can add up
quickly. I think my drops cost me roughly $1/ft since I'm
doing them myself now.

I'm at $17,000 per mile on a recent active E deployment.
Each customer installation averaged $900. This is rural,
so lots of long drops.
I guess I'm looking over to the next stall to see how mine
measures up to yours.

So after the dust has settled on completed projects, what
sort of money have you ended up spending per mile?
How much per customer installation?
