? So much is happening here all the time that we have to catch up on a few things.
While we reported on many events, a construction project in the back of the Lab building has not received any mention. We will remedy this with the next four reports.

The construction project is taking place on the east side of the metal shop, which is located behind the Lab building.
Chief of Utilities at Arcosanti, Scott Riley, planned for this site to be prepared for a second and larger water tank.
We have to go all the way back to the beginning of April, and the crew in these photos are participants of the March workshop.
A big trench was dug right behind the existing water tower, and the crew built a form for a very wide retaining wall, butting up to the metal shop visible on the right of the photo. In the background of the photo we can see the top of the Vaults.

? The workshop participants learned to prepare the wooden forms and the steel reinforcement bars.

? Concrete was moved in wheelbarrows, guided by extra hands down a steep slope …

? …. and guided into the retaining wall form.

? Wooden blocks were placed into the roughly finished surface of the retaining wall …

? … to be removed once the concrete set. The resulting indentations provide a foothold for the concrete wall to be poured on top of this retaining wall.

This report continues on 7/21/10.
