Lots of great new pictures this week, including our first photos from the roof! The construction site is very active this week with crews working to get as much of the roofing and ground cover finished as possible before we get another storm. The roof on both sides of the building is coming along nicely, though the existing side obviously had a head start.
I learned today there’s a lot more to pouring the concrete slab on which the library will rest than just flattening the ground underneath and putting-in rebar. This week the crews are adding 4 inches of rock and gravel to the ground. On top of that there is a material used as a moisture barrier to keep things nice and dry. On top of that there’s another 2 inches of sand! Only once those layers are in place do we get our 6 inch thick concrete slab. Once that’s all in place the crews can move on to walls. Don’t hold your breath just yet, there’s a lot of work to complete in the meantime.
