Two hundred and twenty 20-ton truckloads of shale were brought
in and compacted to create a solid level bed for a 104 ' x 54
' concrete slab. All necessary plumbing was buried in the concrete.
Note bolts potruding at edges. These anchor vertical posts.
This design is known as "monolithic" in that entire
building "floats" on the concrete pad. This virtually
erliminates winter-to-summer expansion/contraction stresses to
both the concrete and the walls.
