Spencer on Byron Hotel, located in Shore City. 23 stories and floor area 1000 sq. m.
An example of a precast cruciform frame construction system.

The example cruciform precast system shown needs only 4 to 6 personnel working 9 hour days to achieve a record 4 days per floor construction rate.

Because the builders, Multiplex Construction, were able to achieve 4 days per floor the structural frame was removed from the building program critical path.
