Plenum floor and steel columns

The plenum floor has been poured; and the steel columns
and beams are set.

When the trusses are placed atop this six foot high plenum, they will be covered with steel and then a layer of concrete. This will form the top of the plenum and the floor of the Temple. The plenum will house the plumbing and electrical feeds, heating and air conditioning ducts, etc., and will be a heated enclosure. This will make the floor of the Temple and its interior comfortably warm on even the coldest winter evenings. The finished Temple floor will stand about two feet above the floor of the adjacent Riverbend Stake Center.
