The hole in our front yard has gotten a whole lot bigger. As I explained earlier, it is the chamber where the gas-based fire extinguishing system for the library basement will be based (full of gas tanks). Once they started digging, they noticed that the garden sat on top of a bed of hardcore cement. Having to pull in the heavy equipment to make the hole, we decided to make it a big one, so we have a bit of extra space down there. They are now laying the cement for the walls (see above picture).
