When the Utah Dept. of Transportation launched, in 2000, its $1.5-billion project to widen Interstate 15 through Salt Lake City, the agency opted for a delivery method called design-build, which was relatively rare at the time.
Ultimately, eight years of planning all came down to eight hours and about 700 ft—the distance traveled by a nearly 400-ft-long, 4.3-million-lb railroad truss on four self-propelled modular transporters, or SPMTs, during the last Saturday of August in Chicago.
Holes drilled at a 30-degree angle rather than vertically, plus inadequate decking, contributed to the Aug. 21 subway station project excavation blast that broke several store windows on the east side of Manhattan in New York City, according to preliminary investigation results.
Driven by steady ridership growth, Dallas Area Rapid Transit is on a roll, using alternative project delivery methods and composite materials as it expands its light-rail system and upgrades its commuter rail.
A design guide for three short-span, heavy-load bridge applications using patented recycled-plastic components is now available, reflecting what officials say is an acceleration of industry interest in the material.
Alternative project delivery methods, including public-private partnerships (P3s), may well play an increasing role in New York City-area megaprojects. Officials are exploring the possibility of private sector involvement in a range of upcoming ventures including the $3.6-billion LaGuardia Airport central terminal revamp, the extensions of the Hudson-Bergen and Camden light rail lines in New Jersey, and the $1-billion Goethals Bridge rehabilitation.“We are exploring the possibility of P3s to complement our capital program, and we welcome your ideas,” said James Weinstein, executive director of New Jersey Transit. He spoke at a July 25 forum hosted by Professional Women In Construction and

HSR Authority Chief Clears Air About Project Collapse of China Track Section Highlights Flaws in High-Speed-Rail Program High-speed rail got a sorely needed boost early this month when the California Legislature barely passed a bill to move forward with $5.8 billion in bonds for a 130-mile starter segment through the Central Valley. That vote came just days before delegates converged on Philadelphia for the eighth World Congress on High-Speed Rail, which met for the first
