The State Dept. is pushing ahead with plans to embrace “design excellence” in its embassy construction program, using some elements for a new U.S. embassy in London, now in design, and fleshing out details through a series of documents that will spell out specific Design Excellence program guidelines.

Work on the nation's first public repository for data on disaster and failure events is under way. The National Institute of Standards and Technology expects to launch a pilot website for a broad disaster database early next year. Events stemming from earthquakes, hurricanes, tornadoes, windstorms, community-scale fires, structural fires, storm surges, floods and tsunamis are included in the repository.

Investigating engineer had to wait five years to sound alarm about flawed truss-joist product. “The effort will support development of standards and technologies for effective collection of data on disasters and failures,” in addition to

Research is getting under way to develop prescriptive code language and performance-based design guidelines for a “rocking frame” structural system that relies on vertically post-tensioned shear walls for seismic resistance. The system promises to improve seismic performance, reduce rebar congestion and enhance constructibility, says the engineer developing it.

Southern Nevada’s Nellis Air Force Base is trimming construction costs of a new child development center by nearly 4% by using a unique aerated plastic-riser foundation system.

The 26,000-sq-ft block building consequently required a gas ventilation system, which typically comprises a vapor barrier consisting of a membrane of washed rocks and liquid as well as perforated pipe and fans. Wright Engineers, Las Vegas, proposed a

The Pacific Earthquake Engineering Research Center is calling on seismic engineers, government agencies and researchers to try out a “live” beta version of a web-based interactive tool that will allow them—free of charge—to search, extract and download recorded ground motions for the analysis and design of earthquake-resistant structures. Seismic engineers familiar with the tool are already lauding it, especially for use in performance-based earthquake engineering.

The 2010 PEER Ground Motion Database allows users to select ground-motion records to match the seismic code’s response spectrum or a customized site-specific

A Nottingham, N.H., public works employee was gassing up his truck when he heard a noise and suddenly the roof of the town’s highway maintenance garage collapsed.

Code crafters are lauding a significant process change in reference-standard development that provides markers for progress along the way, directional signals for reaching goals and validation of the standard’s potential impact on energy use and cost. The process, based on energy modeling and analysis, helped the developers of the 2010 edition of the commercial-building energy standard reach their goal of providing a standard that, if followed, could result in a whopping 30% reduction in both energy use and costs compared with use of the standard’s 2004 edition. Crafters of the next edition of the energy standard already are using the

Hoping for a bigger Super Bowl attendance at the Cowboys Stadium in Arlington, Texas, the owner arranged for temporary sections to increase seating capacity. But some of those seats were not ready at game time. Eric Grubman, NFL executive vice president, said the problem was officials “just ran out of time” to complete infrastructure such as railings and steps, and to tighten risers. The stadium owner says that the $1.3-billion stadium was designed to fully accommodate the additional seats. Seating Solutions, the Commack, N.Y.-based contractor charged with installing the temporary seats, had no comment.

Keith Howells, newly installed chairman of London-based global design firm Mott MacDonald Group, is optimistic that Dubai’s gradual emergence from its real estate slump will boost the firm’s fortunes this year. Mott’s recent award of a design contract on the $6-billion Dubai Pearl mixed-use project supports his view that the emirate’s construction market is climbing “off the floor.” Photo: Courtesy of Mott MacDonald Group Keith Howells takes over as chairman of Mott MacDonald Group just as the firm wins a design award on a $6-billion Dubai development. Mott’s work involves design of mechanical, electrical, public health, fire, communications and security

Structural engineers in earthquake zones, long struggling to push the needle forward on seismic design of tall buildings, are celebrating the availability of a new design methodology. They are hailing the tool, in the form of an 84-page guide for performance-based seismic design of high-rises, as a great step forward in developing better-performing buildings that are more economical and constructible. In addition, engineers expect the guide to take some of the agita Photo: Mark Defeo Guide will ease approvals, which were difficult and lengthy for One Rincon Hill (right) and two Infinity towers (left).
