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.

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?

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.

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.

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.

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.

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. ------ Original Message ------ From: "Jason McKemie" <[email protected]> To: "javascript:_e(%7B%7D,'cvml','[email protected]');" <javascript:_e(%7B%7D,'cvml','[email protected]');> Sent: 8/19/2017 3:49:07 PM Subject: Re: [AFMUG] Aerial fiber $/mile 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.
