Accordingly, in office buildings and warehouses and the like, the net rentable or leasable floor area is increased thereby permitting an increase in net revenue generated from rental or lease of the building area. Furthermore, the substantial reduction in the number of elevator shafts whichcan be achieved through the utilization of this system significantly reduces the capital investment in total building costs and in many cases, this capital investment can be reduced by 10 to 12% and higher.

  • the inherently high flow capacity of this service transport system permits a fully integrated threedimensional transport matrix capable of moving goods and people. Consequently, the service transport system provides an important potential for lower power consumption as a fully integrated three-dimensional urban movement system.
  • the service transport system of the present invention is unique in that it inherently includes a wide range of fail-safe factors of construction in addition to its high efficiency.
