To put the scale of the basement into perspective, here is Art Peters and his son Stephen of MGS Concrete pouring the concrete into the forms. The pumper truck is on the street and unfortunately blocked things off for a few hours but at least it is done.
This image was taken from our old garage door looking straight down. The blocks are really just like LEGO and make the forms stage that much easier. They also eliminate a few steps as these pieces now are part of my basement and insulation.
