Assembly ready SIP walls are proving to be significantly heavier than typical pre-cut panels because much of the lumber has already been installed in the panel, which increases the weight of each panel. Although it saves on labor and material waste on the job site, Todd says a panel is sometimes a bit heavier than what two guys can easily lift. Fortunately, the grade-all is available to do the heavy lifting, especially in difficult to reach places, as shown in the photos below. To the left, panels are being positioned with the grade-all so they may be tilted into place with the least amount of lifting.
With a flick of the wrist by the operator, the header over the Master Bedroom window is easily dropped in place with the fork on the extended boom with the grade-all, above.
Walls on mudsills go up quickly, as shown above, in a view from the Living Room looking towards the Master Bedroom wing, and below, in a view of the the Guest Bedroom wing.
The grade-all is shown above and below, carrying framing lumber and hoisting a full 8" staggered stud wall, that is 18' long x 10' high, into place. At the end of the day, a diagonal brace is temporarily attached to the framed wall, shown below at the end of the Guest Bedroom wing.
Todd says he still prefers the assembly ready SIP's to the pre-cut SIP's. In spite of the extra weight, he says they're faster.
