A 3/4 ton pickup might way 9000 lbs empty. Heavier in the front if it's
empty, heavier in the back if it's full. Depending on the exact truck
and what was in it, it's possible the weight on one tire exceeded 2500
pounds.

We use corrugated plastic culvert pipe for access to our septic clean
outs. It happens to be 30" diameter, and we have traffic-rated lids
that go over the top. The original lids were supposed to be rated at
2500# load. One of those cracked when a 3/4 ton pickup rolled over it.
We replaced that with one that was supposed to be "better". It broke
too in a similar 3/4 ton pickup event.
The newest lid seems to be much stronger. We will see, but I remain
somewhat skeptical.
That said. The culvert pipe has never been an issue WRT load. The lids
are another story.

When I was looking at the meter pits made from culvert pipe, one of

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.

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 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.

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

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.

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?
