Thornton Tomasetti, the international engineering firm, announces that registered architect Richard J. Vivenzio, LEED AP, has joined the firm’s New York office as vice president in the Building Performance Practice.

Engineers Ronald M. Jezerinac, P.E., S.E., and Eric Search, P.E. of Thornton Tomasetti are available as expert commentators on questions regarding engineering of structures for resistance to hurricane forces, how existing structures can be retrofitted to better withstand hurricane forces, and damage assessment.

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

The project team built a new steel frame to hold an independent glass wall system around one of Indianapolis’ most recognizable buildings, replacing a surface damaged by storm winds.

When it comes to considering a costly and disruptive façade replacement, it always pays to get a second opinion. That’s what the condominium association at Water Tower Place in Chicago found when faced with ongoing façade deterioration.

Even Babe Ruth would have trouble recognizing the old Yankee Stadium now. The beloved ballpark’s iconic facade – the white scalloped frieze that ran above the scoreboard and billboards – is being pulled down as demolition kicks into high gear.

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.

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.

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.

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.

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.

Architects’ strategies for turning some of New York City’s grandest old buildings into condos are proving their worth despite an erratic housing market.

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.

For the general public, mention of “forensics” most likely brings to mind television shows like the current CSI: Crime Scene Investigation or Quincy, M.E., popular in the late 1970s and early ’80s. For design and construction professionals, however, the word is associated with tragic collapses, such as the 1981 walkway failure at the Kansas City Hyatt Regency, or this summer’s ceiling module collapse in a tunnel that is part of Boston’s Big Dig.

In a delicate operation that has been compared to pulling off a tablecloth without breaking any china, contractors at Milwaukee’s Miller Park have completed the replacement of pivot bearings for the stadium’s operable roof.

Silverstein Properties, Inc. has released engineering reports reflecting the results of a detailed and comprehensive examination of why the Twin Towers of the World Trade Center stood for as long as they did following the Sept. 11, 2001 terrorist attacks, and why they ultimately collapsed.

Engineers who played a critical role in the rescue and recovery efforts at Ground Zero share their experiences and thoughts about the long-term impacts of Sept. 11.
