Step 1: To get the greatest benefits out of wall panels, it is absolutely critical to start with a foundation that is level and square. Plan for any adjustments before the wall panels are manufactured. It may be necessary to start wall panel placement at the center point of the foundation, to equally adjust for any measurement error.

Step 2: Note all measurements required before installation.

Step 3: Measure the subfloor or the slab. Compare this measurement with the dimensions on the placement plans. Check all floor openings.

Step 4: Review the wall panel stacks and adjust for placement. Wall panel manufacturers cannot always stack the wall panels in order, but rather, may have to ship them in a way that produces a shippable stack.

Step 5: Chalk a line in the inside face of the exterior walls.

Step 6: Write the panel numbers on the floor, following the wall panel layout, in order to indicate the location of each wall panel.

Step 7: Set the first two exterior wall panels and fasten together tightly. Nail the wall panels together at the top, middle and bottom of the end studs.

Step 8: Brace each wall panel as it is set. Use 2x4s anchored to the floor or ground to stabilize each wall panel. This is very important for wall stability.

Step 9: Continue setting additional wall panels leaving a couple of exterior wall panels out, to allow the interior walls to be brought in. A few important details to keep in mind:
• It may be necessary to shim to compensate for slab or sub-floor problems. Shim so that there is full contact between the wall panel and the slab.
• Extra caution is required with walls that have plumbing.
• If the slab or sub-floor slopes and you "rack" the walls to get the stud vertical, the openings will no longer be square.
• Long, end-to-end runs of wall panels must be butted together tightly by hand or mechanical means or the run will be too long. This can often be compensated for up-front by purposely undersizing each wall panel by 1/6" 1/8"

Step 10: Continue setting interior wall panels working from the farthest end toward the opening of the exterior wall panels that are not yet set.

Step 11: After setting all interior wall panels, finish setting the remaining exterior wall panels.

Step 12: Install the upper top plates whenever possible, overlap top plates by at least one stud spacing. See diagram below.
