After the two homes were fully framed and dried-in, the thousands of images collected were analyzed to determine the man-hours it took to complete each discreet framing task and how much waste was generated in the process. The results of the Framing the American Dream study are conclusive: The component-framed house required 152.1 man-hours to complete, whereas the stick-framed house required 373.5 hours. It took two and half-times longer to construct the stick-framed version of the floorplan.

SBCA has compiled the articles below to provide a comprehensive guide to the information it has published on R501.3 (from the 2012 IRC) and R302.12 (the same language incorporated in the 2015 IRC).
