...on a parking garage?

The Fairbanks at Cityfront Center in Chicago was built on top of an existing parking garage. In order to support the new football-shaped tower on the center of the garage, a 6-foot deep concrete transfer mat was used to distribute load to the stronger perimeter columns.
Crystal Center

...in crystaline form?

If a tectonic shift sent giant crystals thrusting up through the water’s surface, it might look something like this dramatic arts center prototype by AS+GG. Crystal structures with cantilevers of up to 230 feet are joined at a base beneath the water.
Matrix Gateway Complex

...as a cube?

The Matrix Gateway Complex by AS+GG would be an exception to the rule of monotony in rectilinear buildings. It would provide residents a full 3-D city experience, featuring suspended platforms linking modular housing and community venues.

...like a big "W?"

Walter Towers are Danish architects Bjarke Ingels Group’s latest project in Prague, Czech Republic. Cool design, but will it stand?

Will it stand for another 2000 years?

Even in these technologically advanced times, the massive Roman structures of the first century impress. Perhaps the Romans' most astounding feats were related to their ability to move water. The Pont du Gard of southern France brought fresh spring water nearly 50km from northern highlands to the Roman city at Nîmes. On the way the ancient engineers had to build a 275m long bridge over the Gardon River.

The Pont du Gard is comprised 56 stone arches. The six lower arches are most impressive, 22m high and 6m thick. Making the story of its engineering even more incredible is the fact that it was constructed without the use of mortar. The precision site surveying and construction sequencing were also feats for the ancient world. Remnants of the shoring system can still be seen in the form of stone corbels protruding from the face of the arches. It's amazing to think that block and tackle could be used to lift stones weighing up to six tons. Nevertheless, it's estimated that the Pont du Gard was erected in 3 years, employing up to 1,000 workers.

In the middle ages, the Pont du Gard served as a pedestrian bridge across the river. At one point in history, the middle level of arches were chiseled back to provide a wider platform for horse cart traffic. Fortunately, the bridge has survived that defacement, centuries of forceful river surges and local seismic activity.

The Pont du Gard is an amazing structure. Standing in it's presence, one reflects on the permanence of its construction. How will structures built today age? Will they seem as elegant to our progeny 2000 years from now? The Romans were building an eternal empire; what are we building for?
