ABSTRACT:
A precast concrete module defining a combined elevator shaft and utility chase area that is one story high and stacking of the modules on top of each other during construction, resulting in a completely finished elevator shaft and utility chase at the completion of erection. By this method of construction, considerable installation time following erection is eliminated in view of the fact that many of the components are already preassembled in the module prior to lifting to location.
