Some forward thinking - which we all know is most definitely not a thing when it comes to suburban development patterns - would see these installed from the beginning to ultimately save money long term on maintenance and upgrades.
Since the suburbs are an unsustainable Ponzi scheme designed to cram as much money out as possible though, they will go for the cheapest up-front option, total lifetime cost be damned.
The municipality I lived in previously had a really interesting project where they were trying to improve the lifecycle of underground infrastructure.
Instead of digging up the ground, putting in/repairing something/whatever, and then covering it up, they were going to install a permanent ‘infrastructure tunnel’ which could have installations and repairs be done without digging up and covering.
If successful, this kind of seems like what the shipping container did to the shipping industry, an incredible efficiency play.
Gotta make use of that Force Majeure-clause
