A recent application required two Class 10,000 softwall rooms that were 8' x 8' x 8' for a limited time period. Due to space restraints, the client wanted to stack one cleanroom on top of the other. We designated one unit as a base unit and one as a top unit. The top unit will be lifted by a bridge crane and set on top of the base unit. Special fitting were installed on the corners of each room to allow the top unit to be lifted and receiving fittings were mounted to the base unit to secure the units when in place.
