|A vertical expansion of an existing mall, this complex project included the need to assemble a 165-ton crawler on a 60-foot-tall platform outside of the building. A 55-ton rough terrain (RT) crane was assembled on a structural steel grillage system on top roof for erection. The crawler fed steel to the RT during the day, with the RT erecting the steel at night.
