Spohn Ranch has put up a detailed video showing the installation of a prefab concrete bowl on the U.S. Millitary base in Guantanamo Bay, Cuba. It’s the first time I’ve seen a prefab concrete installation covered so thoroughly. Regardless of your personal feelings about prefab concrete, it’s really interesting to see it all go down. It’s striking how mechanical the whole operation is. It’s progressed to a point where they almost don’t need more than one guy on the crew who whow skatepark specific concrete finishing, it’s very mechanical. The metal coping is cast into the forms. They lower everything into place, shim it up and then pour the flat and the decks. There’s some patchwork on the seams, then welding and grinding the coping and it’s done. The process seems to work well for non-organic skateparks and single feature bowls. Imagine the equivalent of building a skatepark like you would an HO model train. Pick your pieces and arrange them. Vid after the jump.
