Despite mid-winter storms, STI lifted and enclosed 2 adjoining occupied buildings for an international manufacturer and distributor of party-related products – without disturbing the company’s busy 24-hour, 7-day a week operations. The 170,000 square foot lift, raising the roof from 14′ up to 25′ clear, was accomplished smoothly thanks to the non-disruptive nature of the process and the clever technique of having the wall enclosure installed before the lift. The new upper walls rose with the roof as it was lifted to prevent weather exposure. Additional pallet rack, mezzanines, flow rack, and conveyor systems then made productive use of the new space.
