Installing deep utilities in a new subdivision is relatively easy; almost any operator who claims they can dig a triple trench can do it. This is because there's nothing else in the ground...yet.
But let's go to an intersection on Vancouver's Westside, Oakridge to be specific. This development began its construction in the 1950's. Since then they have been burying every pipe and cable known to man throughout this intersection.

not only has to dig around and expose all of the existing lines, but they have to safely and strategically suspend those lines in the air. After all of that, then they can finally begin to lower the 1350 concrete storm pipe down and in between the many obstacles. It's going deep underneath the maze of existing utilities where the ground will never freeze.
Part 2 will have pipe going in the ground! coming soon
