It's fairly involved in an older neighbourhood if the utilities are buried... they installed it in mine a couple years ago, and it involved months of contractors and trucks in the neighbourhood marking utility right-of-ways and hydrovaccing holes in everyone's front yards.
Yep, it was this exactly. 40+ year old neighborhood with buried electric, gas, water, telco. They had to dig up yards, do horizontal drilling under some roads, etc.
They just rip up the roads here. And then a couple months later another company does the same for their fiber because we can't have proper shared utilities anymore.
