Designers begin discussions on the image sketch of "Solar Ark."
Before a blueprint is drafted, a windtunnel test of "Solar Ark" is performed with an exact model to verify various effects of the wind.
A detailed computer analysis is made of the unique body of "Solar Ark"
Verification of external appearance and placement of the solar battery into the "Solar Lab" is made using a full-sized model of "Solar Ark."
The largest columns in Japan are built on a foundation deep underground. These four columns will support "Solar Ark's" total weight--3000 tons.
Steel frame units are put in place in individual blocks using a large crane.
The steel frame units between
the four columns are connected,
enabling "Solar Ark" to be
supported. Construction of frame
units extending to both ends
takes place.
The solar energy museum "Solar Lab" is rised. The "Solar Lab" and "Solar Ark" are established as independent structures.
Placement of the solar battery panel units, each one consisting of 12 pieces of solar panels, begins. Although the panels are made of tempered glass, great care is required in the process.
The upper-top unit is built. The cubic truss structure is completed.
