Versatile Foundation

Revenue-earning Seismic Resistant Structural Foundation

Pile foundations for buildings exist to support the weight of above-ground structures and withstand earthquakes and strong winds. However, structures designed solely for support cannot utilise the space below ground. To address this, we have developed a large-diameter lower structure with superior seismic resistance compared to conventional pile foundations. This structure consists of mechanically stable cylindrical press-in pile continuous walls. By utilising the internal space as a car park or bicycle parking area, we have created a “Revenue-earning Seismic Resistant Structural Foundation”, combining the role of a foundation with additional functions.

The world's first office building with Revenue-earning Seismic Resistant Structural Foundation

Daido Shinagawa Building

In December 2003, the 1st application of “Revenue-earning Seismic Resistant Structural Foundation” office building was constructed near Shinagawa Station, Tokyo Japan. It is a 9 story building. Its anti-seismic foundation is consisted of two units of the ECO Park™ and one unit of the ECO Cycle™ and an underground chamber.

* ”ECO Cycle”, ”ECO Park” is certified by Japan’s new Ministry standards.
