Tall Order

摘要

A Chinese company hopes to erect the world's tallest skyscraper (2,749 feet) in just five months using prefab modules ("High-Speed High-Rise," issue 20.10). Broad Sustainable Building claims its towers are environmentally and seismi-cally superior to conventional structures. It remains to be seen whether the company can pull it off, but in any case, some readers say they'd want more information before darkening the door of a factory-made tower.
