Underground Development

Culture aboveground, function underground

The GIKEN Group developed ECO Park™, an earthquake-proof, fully automated mechanical underground car parking facility, and ECO Cycle™, the same for bicycles, under the concept of “culture aboveground, function underground.”
With press-in technologies developed over years by the Group, these systems are delivered as total packages offering everything from planning to construction and functional maintenance, and management after installation.

The role of GIKEN SEKO is to complete the construction part of these projects, from the press-in work required when constructing the frames to installation of mechanical equipment. The company has developed construction methods that use prefabrication, and do not need temporary works, to achieve rational and rapid construction. In this way, the continuous walls, constructed by installing piles in a cylindrical shape, can be used directly as earthquake-proof structural walls for the car and bicycle parking facilities.

Completed projects (as of August 2022)
・59 ECO Cycle units
・6 ECO Park units
