Stages of SIPS Panel Construction - Week 6

The past week has been spent raising interior truss braces, cutting window openings, and installing lumber. On Friday, we brought a 30 ton all-terrain crane out to the job site to set roof panels. With the crane we were able to set 32 panels in only 6 hours!

The photos will show how we attached two lift plates to the top of each panel. Using 3/8" lag bolts, the plates were fastened through the top OSB layer and then screwed into the top chord of the I-joist contained in the middle of each panel. Once placed on the roof, the panels were pulled snug into place using a ratchet system.

Interior bracing trusses were set using a forklift. Window openings were cut with a circular saw on both the interior & exterior and then the remaining foam was cut with a reciprocating saw. We chose this method to achieve a cleaner cut with greater accuracy. Once each plug was removed, foam was recessed 1 1/2" around the openings and then 2x10 wrapping was installed.
