Paul Rea teaches how to frame a "crawl space" underfloor for a residential building using traditional 2x10 joists. He shows the components of the underfloor including the mudsill, vapor barrier, anchor bolts, joist hangers, and pony wall. He also discusses why pressure treated lumber is used for the mudsill and where to put the crawl space access to the underfloor. See actual video of mudsill installation, joist hangers installed, and the sheeting of the subfloor. The building is a Single Family Residence with an attached Accessory Dwelling Unit (ADU) located in Springfield, Oregon. Paul Rea is a Construction Technology professor in Oregon at Lane Community College.
