London bridge may fall, paper bridge may not

Shigeru Ban is an accomplished Japanese and international architect, most famous for his innovative work with paper, particularly recycled cardboard paper tubes used to quickly and efficiently house disaster victims. Shigeru Ban was the winner in 2005 at age 48 of the 40th annual Thomas Jefferson Medal in Architecture from the University of Virginia in Charlottesville. He was profiled by Time Magazine in their projection of 21st century innovators in the field of architecture and design.

Shigeru Ban studied at the Southern California Institute of Architecture and later went on to Cooper Union’s School of Architecture where he studied under John Hejduk and graduated in 1984. Hejduk was a part of the The New York Five. From Hejduk, Ban learned not only fundamental elements of architecture, but also gained an interest in ‘architectonic poetics’ or the creation of three-dimensional poetry. Hejduk, the most experimentally minded of the New York Five, had a lasting influence on Ban, whose work has continuing explorations into basic geometric elements. Ban’s formal explorations with basic building materials helped to lead him into unique structural solutions.

Ban is most-famous now for his innovative work with paper and cardboard tubing as a material for building construction. He was the first architect in Japan to construct a building primarily out of paper, with his paper house and required special approval for his building to pass Japan’s building code. Ban is attracted to using paper because of its low-cost, its recyclable, low-tech and they’re replaceable. The last aspect of Ban’s influences is his humanitarianism and his attraction to ecological architecture. Ban’s work with paper and other materials is heavily based on its sustanability and because it produces very little waste. As a result of this, Ban’s DIY Refugee shelters (used in Japan after the Kobe earthquake, in Turkey, Rwanda and around the world) are very popular and effective for low-cost disaster relief-housing.

When the Japanese architect Shigeru Ban was asked to build a footbridge over the Gardon River in the south of France, he designed one that was keenly sensitive to its surroundings. He constructed it from locally available materials and based its geometry on the nearby Pont du Gard, a historic Roman aqueduct. Ban used a mixture of cardboard tubes, recycled labels and creative engineering.

The surprisingly strong structure can withstand the load of at least 20 people, rose triumphantly against the backdrop of the ancient monument. The 72-foot-long frame was made primarily from 281 cardboard tubes — each four and a half inches in diameter and about three-quarters of an inch thick. The tubes were held together by steel joints. For the steps, Ban used a new material called ProFi, assembled from paper and plastic left over from the manufacture of self-adhesive labels. Wooden boxes buried underground and packed with local sand formed the foundations.

The bridge diameter and curvature were modeled on the classic proportions of the Pont du Gard’s arch. “It was an interesting contrast,” Ban says. “But it was both a contrast and a harmony.” The design of the bridge allows for easy assembly and dismantling. It took a team of architecture students only a month to complete the installation, which remained open to the public for six weeks before being dismantled in August before the rainy season. Ban says he expects it to be rebuilt next year.

The main challenge, Ban says, was not mastering the engineering of the bridge but persuading skeptics to rethink basic principles of design. “The strength and durability of a structure has nothing to do with the material,” he said. Ban fits well into the category of “Ecological Architects” but he also can make solid claims for being modernist, a Japanese experimentalist as well as a rationalist. “I don’t like waste” is an apt quote from Ban, summing up his philosophy, known as “Paper George's Architecture.”
