Yesterday the snow had all but disappeared. But winter returned this morning, just in time for the cement flooring to arrive. Here you see a cement truck feeding concrete into a pumper truck. The pumper is equipped with a long, flexible arm that directs the concrete into the facility where it is being poured onto the floor and leveled by the workmen inside. The floors will be poured for the entire facility - repository and lab space - but this is only the first pour for the repository. Once it has cured, the metal tracks will be laid for the mobile shelving and a second pour will set them in place.
