Numerous structures are on course for completion in time for the London 2012 Summer Olympics, including a few that are uniquely shaped. Perhaps the strangest is a steelwork monument that will rise 114.5 meters, serving as an icon for the Olympic Park.

The structure is the
The Minneapolis Metrodome, ripped and deflated after blizzard-like conditions in December, will be replaced after engineers questioned the safety of the entire fabric dome. The Metropolitan Sports Facilities Commission, which operates the 28-year-old Metrodome, is taking proposals for the job, which will cost an estimated $18.3 million. Offerings are due by Feb. 23, and the work is to be completed by Aug. 1. The dome, a two-layer fabric structure supported by fan-blown air and held in place with steel cables, has been under study since December after snow and ice ripped holes in the fabric and caused it to collapse.
After a lengthy delay in picking a site, plans to build a new $500-million Social Security Administration data center are moving ahead. Federal officials finally selected a site in Urbana, Md., in early February and a request for qualifications for a design-build team for the project is on the street. The 400,000-square-foot project is one of the largest new buildings funded by the 2009 American Recovery and Reinvestment Act. The stimulus act provided $400 million to cover the construction cost, plus $100 million to partially fund equipment for the new center. The project was the focus of a Feb. 11
In an attempt to prevent a Las Vegas-style resort/casino from being built near Glendale, Ariz., Gov. Jan Brewer (R) signed a bill into law allowing Glendale to annex the 54-acre site. Casinos can be built only on tribal land, according to the state’s Indian Gaming Compact. However, as the law takes effect in 90 days, the window is open for legal maneuverings by the project’s developer, the Tohono O’odham Nation. Despite a scaled-back design, West Valley Resort still faces opposition. The bill, HB 2534, was pushed through the Republican-controlled Legislature last month but failed to reach a two-thirds majority that
History keeps disproving predictions that the supertall skyscraper, as a developer’s building type, was destroyed when the two 110-story towers of New York City’s World Trade Center went down. Last year alone, 66 towers taller than 200 meters opened their doors, breaking the 2007 record of 48. Of these, eight are taller than 300 m, according to the Council on Tall Buildings and Urban Habitat, which is the keeper of the tall-building flame. CTBUH predicts 97 more 200-m-plus high-rises will have ribbon-cuttings next year, including more than 20 taller than 300 m, which the group dubs “supertalls.” “Immediately following the
After delays attributed to the global economic recession, construction has begun on two of Abu Dhabi’s five planned cultural buildings—the Louvre Abu Dhabi and the Guggenheim Abu Dhabi museums. The five facilities will form an emerging cultural district on Saadiyat Island, located 500 meters from the city of Abu Dhabi, which serves as the capital of the United Arab Emirates. Officials at Abu Dhabi’s Tourism Development and Investment Co. (TDIC), which is developing the island, say they are using the recession to take advantage of reduced prices in construction materials and equipment. TDIC officials decline to give a value on
An extensive program to survey and monitor the structural behavior and dynamic responses of the world’s tallest structure—the 828-meter Burj Khalifa in Dubai—has done more than validate the structural engineer’s design concepts. It could help improve future supertowers, says the keeper of the program. The monitoring system, which includes myriad sensors, will become a model for assessing critical and essential facilities, predicts Ahmad Abdelrazaq, an executive vice president of Samsung C&T Corp., Seoul, the burj’s lead builder.

Some see a frozen tear clinging to the “cheek” of the new Salvador Dalí Museum in St. Petersburg, Fla. Others see a melting crystal. Depending on the viewer’s vantage point, still others say they are reminded of a misshapen potato, a nose, an amoeba and a dolphin in a nosedive. The builders of the glazed atrium structure that drapes over the side of the boxy building simply call it the “enigma.” After all, the builders had to solve a mystery of how to shape, engineer and hang a transparent and organic structure—75.5 ft at its tallest, 105 ft at its
In Lower Manhattan, the steel on the World Trade Center’s Tower 1, formerly know as Freedom Tower, on Dec. 16 reached its halfway point—the 52nd floor—Tower 4 is at the 9th floor, and the north memorial pool had a successful water test in late November. The steel for the atrium that will lead to the below-grade memorial museum was also put in place in mid-December. “It’s a fantastic time in the project,” said Quentin Brathwaite, assistant director of program logistics for the Port Authority of New York and New Jersey’s WTC construction program, at the start of a talk hosted
Anewly opened $4-billion Las Vegas mega-resort will test the city’s recession-racked, tourist-based economy, while concluding years of work for 3,220 tradespeople and construction staff responsible for the 2,995-room, 7-million-sq-ft Cosmopolitan Casino Resort. Photo: Bill Hughes The Cosmopolitan was the right hotel-condo-casino at the wrong time, a source says. Characterized in one media report as the city’s “most expensive debacle,” the bank-owned hotel complex, set to open a year late on Dec. 15, epitomizes Vegas’ real estate boom gone bust. Developers broke ground on the project, originally valued at $1.8 billion, in late 2005 with little cash down. The price tag
