Over the next several decades, developments in the area of carbon nanotubes and in the ability of computer programs to accurately model molecular behavior could lead to building materials that perform dramatically better than existing materials.

When the New York Times Company decided to construct its first new headquarters in 94 years, the design process led to a technically and architecturally sophisticated structure that is one of the tallest buildings in Manhattan. The 52-story tower—topped by a 300 ft (91 m) mast—features a structural frame of external, exposed steel columns and bracing that makes the building appear light and transparent, and the unique facade system seems to disappear into the sky.
By Michel Moussard, P.E., and Michel Virlogeux, Ph.D.
A new lift bridge in Rouen, France, features two movable spans 120 m in length that are operated independently by the structure’s elegant system of pulleys—the “butterfly”— atop the piers.
By Peggy Hagerty Duffy, P.E., M.ASCE
The presence of sinkholes and related features can complicate construction in regions with karst geology. Such was the case with the recent development of a new hospital in southern Indiana, which involved designing and installing stable structures capable of conveying storm-water runoff belowground without erosion. After some of the underground features became unstable during construction, quick action and creative field techniques were required to keep the project on track and on budget.
