Thornton Tomasetti Irvine Principal Leonard Joseph, P.E., S.E. and New York Senior Principal Hi Sun Choi, P.E., LEED AP have been named co-chairs of the Council on Tall Buildings and Urban Habitat’s Outrigger Design Working Group.

The 2010 annual Stirling Prize from the Royal Institute of British Architects (RIBA) is the third architectural project engineered by a Thornton Tomasetti principal to win the U.K.’s top architectural award.

Dennis Poon has been named one of the 50 Outstanding Asian Americans in Business for 2010.

Thornton Tomasetti received Diamond and Platinum Awards for Engineering Excellence from the American Council of Engineering Companies of New York (ACEC New York) Engineering Excellence Awards for the structural design of Comcast Center in Philadelphia and Carrasco International Airport in Uruguay.

Joseph Burns will moderate a panel on “Minimizing Change Orders Through BIM Utilization” at the 2010 Airport Consultants Council/American Association of Airport Executives Airport Planning, Design & Construction Symposium.

Thornton Tomasetti, the international engineering firm with practices in building structure, building skin and building performance, was the structural engineer for three Midwest-based projects receiving top honors from Midwest Construction magazine.

Detailed modeling & analysis of the numerous load cases enabled us to extend the service life of New York’s Roosevelt Island Tram.

The dramatic roof covering the new terminal at the Aeropuerto Internacional de Carrasco in Uruguay, was designed to compliment the site’s undulating, seaside surroundings.

When the wrecking ball came down on San Francisco’s 71-year-old Transbay Terminal bus station in December, it marked the end of an era—and the beginning of a new one. The drab concrete structure will be replaced with the long-planned Transbay Transit Center, perhaps the most ambitious transportation hub to be built in the United States in the past few decades.

The new Fedex cargo facility features a massive green roof at Chicago O’Hare International Airport.

Even during a time of dwindling capital and stalling public works projects San Francisco is moving forward with plans for a $4.2 billion transportation center that could dramatically change how the city looks and travels.

The new Carrasco International Airport, opened in 2009 and designed by Uruguayan-born architect Rafael Viñoly, is a gorgeous throwback to JFK circa 1960.

The completely rebuilt Roosevelt Island Tramway opened today, following a nine-month modernization project which replaced the previous 33-year-old tram system. The new tram reduces travel time, permits both cabins to start on the side with highest demand during rush hour, and includes extensive safety measures.

After decades of planning, construction work on the Transbay Transit Center officially began Wednesday following a politician-heavy groundbreaking ceremony.

The UK Pavilion at the World Expo 2010 Shanghai by Thomas Heatherwick Studios, Timberyard Social Housing in Dublin by O’Donnell & Tuomey and the Anchorage Museum in Alaska by David Chipperfield Architects are the three contenders for the Royal Institute of British Architects’ (RIBA) prestigious RIBA Lubetkin Prize for the best international building by an RIBA member.

San Francisco’s ambitious $4billion Transbay Transit Center Project can now move forward following the closure of a $171 million Transportation Infrastructure Finance and Innovation Act (TIFIA) loan deal for the project.

Three decades in the planning and three years in construction, the final costs of the new passenger terminal and other midfield developments at Indianapolis International Airport remain pegged on budget at $1.07 billion.

Last year, Memphis International Airport (MEM) handled 4.2 million tons of cargo – more than any other airport in the world for the 17th year in a row. Memphis-based FedEx Corporation accounted for all but 2% of the volume. To move that kind of tonnage, FedEx needs big cargo planes. To service the planes, it needs a big hangar. A 146,257-square-foot hangar, to be exact.

San Francisco is a world-class city, but we have always missed one thing – a real, world-class train station. That is about to change. After years of planning, we are ready to break ground on a new, multi-modal, state-of-the-art public transit facility – the Transbay Transit Center – which will connect regional bus lines, including AC Transit, with BART and Caltrain and eventually, California High Speed Rail.

In 1992 a study commissioned by the Indianapolis Airport Authority (IAA) confirmed the need for a new midfield terminal complex. In 1996, the annual passenger volume exceeded seven million for the first time, and the following year a new Terminal Master Plan Update for the airport put forth a new terminal project, in preference to expanding the existing terminal.

Thanks to federal largesse and the Legislature’s only override of a Tim Pawlenty veto, Minnesota now boasts the most aggressive highway bridge repair and replacement program in the nation.

Contradicting the National Transportation Safety Board’s report that blamed too-thin gusset plates for the Aug. 1, 2007, collapse of the Minneapolis Interstate 35W bridge, an independent analysis has concluded that rusted, frozen roller bearings prevented thermal expansion and caused a truss chord to fail, triggering the gusset-plate failure. The analysis by Thornton Tomasetti, New York City, using forensic bridge information modeling, was presented to victims’ families and will be deployed in an anticipated lawsuit

An engineering firm hired by attorneys for victims of the Interstate 35W bridge collapse says the cause of the disaster was not undersized gusset plates but the failure of a nearby beam, a lawyer for the victims said Wednesday. The firm’s findings directly contradict the conclusion reached by the National Transportation Safety Board.

Experts from engineering consultancy Thornton Tomasetti believe that the initiating event wasn’t the fracture of a key gusset plate in the bridge, but the failure of a horizontal beam.

Lawyers for more than 100 bridge collapse victims say the National Transportation Safety Board reached the wrong conclusion about the 35W bridge collapse. A consortium of lawyers hired the international consulting firm Thorton Tomasetti to investigate the collapse. The firm also investigated the collapse of the World Trade Center.

Experts hired by attorneys for victims of the Interstate 35W bridge collapse say the National Transportation Safety Board got the cause of the disaster wrong, their lead attorney said Wednesday.

The National Transportation Safety Board got the cause of the Interstate 35W bridge collapse wrong, the lead lawyer for most victims of the disaster asserted. The lawyer, Chris Messerly, said experts from the engineering firm Thornton Tomasetti Inc. told survivors and families of victims Tuesday night that the “initiating event” was not the fracture of a key gusset plate in the Minneapolis bridge, as the safety board concluded, but the failure of a horizontal beam called a chord.

With just two months until scheduled completion, contractors at the Naval Air Station in Jacksonville, Fla., are putting finishing touches on the U.S. Navy’s largest hangar, which is being built to make room for five squadrons coming from Maine under the government’s Base Realignment and Closure program.

For most airports, increasing capacity means adding a new terminal or expanding an existing one. This fall, however, passengers flying into and out of Indianapolis will be passing through not just a new terminal but a completely new airport.

Bridge engineers and software providers are adapting and customizing building information modeling techniques for everything from new designs to forensics. But an industry-wide standard for such modeling remains to be seen.

In a sign of the intensifying political turmoil surrounding the investigation of the Interstate 35W bridge collapse, Congress will publicly question the National Transportation Safety Board (NTSB) next month about its investigation, including the agency’s refusal to hold a hearing of its own.

By year-end, passengers at Indianapolis International Airport will come and go from a new terminal and 7,100-car parking deck, all part of a $1.1-billion improvement project more than 30 years in the making.

In the early morning hours of August 17, 1999, a tremendous earthquake with a magnitude of 7.4 on the Richter scale struck northern Turkey. Many buildings in and around Istanbul sustained damage from the temblor, even though the epicenter was about 100 km east of Istanbul near the port city of Ismit.
