Geometry Lesson

Here the crew is building the form for the footing, which will be poured later today. This photo really shows the funkiness of the geometry of the dome's base; it's a lot of irregular* angles (fourteen in all) and different wall lengths to accomodate the entrance & window dormers.

In response to a question in comments, we are building a 48-foot concrete dome from a kit by American Ingenuity. (Domes are always measured by their diameter at the base.) The construction crew will build the dome shell & frame the interior, but Mike will be doing all the finish work. I get to pick out the paint colors! :-)

* "Irregular" is here defined as "not 90 degrees, which is what the concrete guys are used to".
