Modular assembly of a first floor section of Duplex 2 at the All American Homes manufacturing facility. This work is being performed parallel with the job site where a foundation is being constructed that will receive these systems built units in a couple weeks.

Example of siding crew installing concrete siding over a ½ rigid exterior foam. The foam acts as a break in the thermal bridge that ultimately the loss of energy that occurs through the wall frame. Note the solid scaffolding and controlled working environment for high quality craftsmanship. Photo taken 4/08/09. First official pour of concrete into our Forma Drain foundation footing forms. These forms double as perimeter drain tile as well as radon ventilation if needed. The forms were erected under supervision of and training by our Workforce Boulder County Green Jobs crew. Photo taken 4/15/09. Our Green Jobs crew is learning the old fashioned way of placing concrete using a wheel barrel to better appreciate the craftsmanship of building a foundation and new technologies afforded by concrete pump trucks.
