48 Carrying the Torch
By Jeff L. Brown
As this summer’s Olympic Games begin, the eyes of the world are on Beijing’s new National Stadium. The building—popularly known as the Bird’s Nest—was designed to appear chaotic, but an inside look reveals an intricately complex structure.
56 Precise Prediction
By Michael T. McNerney, Ph. D., P. E., M. ASCE
Using a new and more accurate method for predicting the remaining service life of airfield pavements, a civil engineer was able to assist Denver International Airport in developing a rational and cost-effective pavement slab replacement program.
64 Distributing Denver’s Recyled Water
By Matt S. Turney, P. E.
Relying to an increasing extent on recyled water to help meet demand, Denver Water is expanding its distribution system for such water. As part of recently completed project, Denver Water added a reservoir, a major pump station, and 6.5 mi (10.5 km) of new transmission mains. The design and construction of conduit 307, a 4 mi (6.4 km) long segment connecting the reservoir and the pump station, entailed many challenges related to heavy traffic, confined working spaces and public relations.
70 Successful Launch
By Ahmad Khashan, P. E., Robert Gale, P. E., P. Eng., Paul Hopkins, and Greg Orsolini, P. E.
A design/ build team relied on a skillful launching method—one that had never before been tried on such a scale in North America—to erect a curved steel girder bridge high above a river and the floor of a steep and treacherous canyon in British Columbia.
