Lifted 27,000 square foot roof section, from 16 feet up to 28 feet clear, to enable installation of crane for Fortune 500 manufacturer of high-tech laser-guided fork-lift equipment. Preparations were installed while ongoing operations continued undisrupted in the occupied building. The new upper walls were installed around the building, and attached to the roof prior its lifting, so that it rose into place as the roof was lifted, providing security and weather protection.
