Versatile Foundation: Underground Car Parking
Foundation piles and reinforced concrete footings are constructed to support the load of the superstructures and to protect the building against earthquake and strong wind. Thus, they are constructed for unexpected events, like insurance. It is the fact that it is not performing full capability in usual.

Versatile Foundation: Underground Shelter
GIKEN created a fundamental system which can support superstructures as a strong anti-seismic foundation and can provide multi-functional space inside the foundation. The shaft, so called the Implant Shaft, is formed with continuous piles which are installed by the Press-in Method. The foundation is not only just a structure to support but also a structure to “make money”. Underground space created by the Giken Shaft can be conveniently utilised for car and bicycle parking lots as well as computer server storages and a shelter to protect properties and human lives from earthquake and flooding.
