Bright and early,
construction crew prepares to pour two precast panels. Pours are
done early in the day to avoid the mid-day heat which is a difficulty
for both the workers and the wet concrete. [Photo & Text: MS]

The formwork for the
two precast panels. The concrete is poured onto a thin layer of silt in
the bottom of the form to achieve an earth-tone textured finish that
comes with this unique process. Forms can take anywhere from a few days
to several weeks to assemble, depending on complexity. [Photo & Text:

The forms are
strategically assembled on top of the slab to minimize the distance
that each panel will have to be hoisted once it has cured. Here the
bucket is being lowered and filled for the next load. [Photo & Text:

The crew must work
quickly in the low humidity of the Sonoran desert. Here the crew splits
and begins pouring the second panel while simultaneously finishing off
the first. [Photo & Text: MS]

The finished panel.
At Arcosanti all precast panels are poured with concrete rated at 3000
psi. It will take two weeks until the concrete hardens to eighty
percent strength and can be moved. [Photo & Text: MS]
