A crew of 3 low skilled men can install a building using standard 4’ x 8’ wall panels at a rate of about 4-5 minutes per panel or about 1 minute per perimeter lineal foot. Floor and roof panels may be 30% greater pending degree of difficulty, elevation off the ground, size of panels, weight, etc. Panel installation is speedy due to one-piece corner panels, quick joining interlocking cam-locks and windows and doors bonded into the panel at the factory.
