Laying the Foundation: Phase 4

Concrete was poured for the foundation today, August 4, 2010

Side walls were completed in the morning and concrete was delivered shortly thereafter. If I heard right, 42 cubic yards of concrete was ordered for the foundation. That's a lot of concrete. A cubic yard of concrete is 27 cubic feet, equivalent to a 3' x 3' x 3' box. Stack 42 of the boxes to make one very large Rubic's Cube. Imagine a 126' long, 126' wide, and 126' high Rubic's Cube worth of concrete. I saw three large cement trucks at the site and was told that more were on the way.

The pouring is done using a cement truck fitted with a crane. The crane hoists a flexible hose that delivers the cement to the framed side walls, where a worker guides it to fill the frame. Workers who do this must have sure footing and strong arms, as the photos below will illustrate.
