I was referring to electrical distribution or transmission. Putting in a 2" conduit with some glass in it is a different beast than 34kv or 345kv lines. :-) ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Jared Mauch" <jared@puck.nether.net> To: "Mike Hammett" <nanog@ics-il.net> Cc: "Rod Beck" <rod.beck@unitedcablecompany.com>, nanog@nanog.org Sent: Tuesday, February 16, 2021 8:38:11 AM Subject: Re: Texas internet connectivity declining due to blackouts

It's cheaper to build 2x, 3x, 4x the aerial plant than to build 1x the underground plant.
The actual cost per foot is more like 10x difference, but there are right of way, maintenance, etc. costs to factor in as well.
Labor is something in 8x but the permit/engineering cost is usually the same per foot, but the make-ready on poles can make underground competitive or more like 1.5x when you fully bake the costs. Really depends on pole distances and quality. O&M long-term is lower on underground vs aerial. - Jared
