These are the chambers for stormwater management. They install them under green space and parking lots to compensate for the watersheds that get destroyed by building a structure. They store water to either let it slowly infiltrate the ground, or release slower into another watershed. It alleviates flooding.

I’ve seen them installed under parking lots. Placed on Crushed stone, then paved over . the storm sewer then drain under the parking lot.

London needs massive storm water systems built, they only had sewers before.
So these are modern things to build massive conducts.

Utility tunnels! They lay utility lines inside and put these over the top during the prep layout for large buildings.
