The expressed steel framing for the grand-scale sculptural transit hall of the WTC’s Transportation Hub, designed by architect-engineer Santiago Calatrava to evoke a dove of peace, already has been simplified to keep it from literally flapping its wings. Yet it still is going to be “as challenging a steel project as it gets,” says Dan Payea, vice president of operations for Skanska Koch, a Carteret, N.J.-based division of Skanska Civil

The skyscraper is expected to cost $1.2 billion. If a Middle East prince has his way, Saudi Arabia will someday be home to the world's tallest building. Alwaleed Bin Talal Bin Abdulaziz recently unveiled a scheme for a 5.3-sq-kilometer city north of Jeddah that would include a mixed-use supertower designed to reach more 1 km above the desert floor.Kingdom Tower, under design by Adrian Smith + Gordon Gill Architecture, with
After years of chugging along, the development of the nation's first consensus-based standard for the use of building information modeling is finally picking up steam. The buildingSMART alliance, which is releasing the National BIM Standard-United States, or NBIMS-US, says a version of the standard will be out by year's end. Beginning on Aug. 3, the 30-day public-comment period will broach the 45 topics that form the core of the standard.“We're out of the back room,” says Deke Smith, executive director of the alliance, which is a council of the National Institute of Building Sciences, Washington, D.C.Smith and his colleagues have
Hooray, Arrays! Image Courtesy of NREL The National Renewable Energy Laboratory in Colorado. Thanks to its arrays of photovoltaic cells with a total production capacity of 973 kW, the nation's largest net-zero energy-use building produced as much energy as it used on June 22. National Renewable Energy Laboratory researchers in the Dept. of Energy's 220,000-sq-ft Research Support Facility expect the Golden, Colo., building to achieve NZEU for the month of July, assuming the sun continues to shine. DOE's Jeffrey M. Baker, the facility's visionary and ENR's 2011 Award of Excellence winner, reports the year-old building is performing as designed (ENR
Architects and structural-steel, concrete and masonry interests fighting the “wood first” movement are breathing a collective sigh of relief since Oregon legislators adjourned for the year on June 30 without enacting legislation that would give wood a leg up over other framing materials for use in public buildings.

Builders of a 201,000-sq-ft art museum set in a blasted-out ravine in northwest Arkansas knew they would be digging themselves into a hole when they signed on to construct the pet project of Alice Walton, heiress to the Walmart discount chain-store fortune. They were prepared for headaches associated with the job's remote location in Walton's 120-acre forest. They had braced themselves for building structures, dams and ponds in a flood-prone streambed. And they were prepared for architect Moshe Safdie's curved forms and cable-supported roofs. “We were quite intrigued by the cable structures across the creek—which to our knowledge had never
Georgia Institute of Technology professor Charles M. Eastman, long considered a research guru for computer-based building design and construction, displays parental pride in his latest brainchild: Georgia Tech’s Digital Building Laboratory. Unlike Eastman’s past efforts, starting some 40 years ago, the fledgling DBL, created in 2009 to help improve building design and construction through the aid of digital tools, is a collaboration among academics and players in the buildings-sector food chain. “This is industry and academia together,” says Eastman, DBL’s director and a professor of both architecture and computing at Georgia Tech, Atlanta. “To me, it is so obvious that
