Building to arrive via flatbed truck. The carrier must contact end-user 24-hours prior to
delivery to arrange for off-loading. Use either a forklift or overhead crane to off-load the
building from the flatbed. If an overhead crane is used, be sure to use “spreader bars” to
prevent the building fascia/roof from being damaged by the sling/straps. Square the
building on the pad and anchor.
Recommended concrete anchor is ½” x 4” galvanized or stainless steel, or comply with
local codes – whichever is most stringent. Anchors are provided by site-contractor.
Make final electrical connections and clean the work area.
