The National Gallery of Art’s East Building in Washington, D.C., is preparing for an emergency facelift. Some of the marble panels on its exterior are tilting outward, indicating problems with its veneer panel support system, according to Deborah Ziska, gallery spokeswoman. The panels are attached to the building’s exterior with stainless-steel anchor and clip supports. Local structural engineering firm Robert Silman Associates recommended the removal of all the gallery’s 16,200 panels, reinstallation with new supports and installation of new gaskets between panels.

Federal infrastructure stimulus announced in February could pave the way to faster development at Sacramento’s 244-acre Railyards. The long-planned mixed-use project owned by S. Thomas Enterprises was selected by the Sacramento Area Council of Governments to receive $20 million in American Recovery and Reinvestment Act (ARRA) funds. The stimulus funds will push work on track realignment and road building ahead by six months, according to Suheil Totah, vice president of Thomas Enterprises. “This is tremendously significant for the project because the money wasn’t expected and now we will be able to move forward on items that had been put on

A federal judge in New Orleans ruled on March 20 that a civil lawsuit against the U.S. Army Corps of Engineers brought by homeowners who suffered flood damage in Hurricane Katrina in 2005 can proceed. The suit claims the Corps is liable for levee failures along the Mississippi River to Gulf Outlet, a navigation channel. The Corps has immunity from claims arising from flood-control failures but does not have the same protection with respect to navigation infrastructure. Judge Stanwood J. Duval Jr. said “substantial questions” have been raised. Damages could reach $100 billion.

The American Society of Civil Engineers released its comprehensive 2009 Report Card for America’s Infrastructure on March 25. ASCE released a preliminary report of the national letter-grade findings on Jan. 28, assigning the nation’s roads, bridges, water systems and other critical infrastructure a cumulative grade of D and noting a five-year investment need of $2.2 trillion. The version now out breaks down the data in state-by-state detail. See www.asce.org/reportcard.

Warm-mix asphalt is hot. Asphalt industry officials believe warm mix, porous asphalt pavement and reclaimed asphalt pavement (RAP) will come to dominate paving in the next few years because the products offer lower costs and higher environmental benefits than traditional hot mixes.

Alow-profile 350-meter-long, 15-m-wide suspension bridge designed by a U.K.-French team will carry part of a 25.5-kilometer planned light-rail system, called Metro West, across Dublin’s Liffey River to the city’s northeast corner. The Irish government’s Railway Procurement Agency, which oversaw design competition, wanted a low-key design. “Because it’s sensitive, we didn’t want [tall] towers,” says Davood Liaghat, technical director at Buro Happold Consultants Ltd., Bath, U.K. The structural firm, with Paris-based Explorations Architecture S.A., won RPA’s com-petition and a $190,000 prize.

In a twist on the proverb “Set a thief to catch a thief,” physicists at the University of Texas at Austin have designed a system to facilitate the disposal of spent nuclear fuel that combines nuclear fission with fusion. The hybrid system will destroy 99% of the spent fuel, and the waste that remains will be less toxic than the spent fuel now accumulating in storage at nuclear powerplants around the country, the researchers say. President Barack Obama’s decision to halt further development of the Yucca Mountain nuclear-waste repository in Nevada and “devise a new strategy toward nuclear-waste disposal” has

CityCenter, the still-under-construction megaresort on the Las Vegas Strip, faces mounting challenges in reaching completion. The project, touted as the nation’s largest privately funded development, has tried unsuccessfully for months to obtain a $1.2-billion loan to finance the final leg of construction. Now its partners are fighting in court. The $9.2-billion CityCenter, which includes 19 million sq ft of hotels, homes and entertainment space, broke ground three years ago. On March 23, project partner Dubai World, a conglomerate owned by the Dubai government, sued developer MGM Mirage in Delaware Chancery Court. The timing couldn’t be worse: MGM Mirage is cash-strapped

Progress on two major European skyscrapers may not represent the green shoots of economic recovery, but they help lighten the gloom. In London, pile work is just starting on the 310- meter-tall “Shard,” planned as Europe’s second-tallest building. Elsewhere, workers in Frankfurt are beginning to mobilize the planned Tower 185.
