  Although some key market indicators, including a recent survey of backlogs by the Associated Builders and Contractors Inc., show construction activity in the Midwest trailing activity in the South and Northeast, the region led in February's Architectural Billings Index (ABI), according to the Washington D.C.-based American Institute of Architects.The index, which provides a glimpse of future nonresidential construction spending activity, remained in positive territory in February for the fourth month in a row, with a score of 51.0, up from 50.9 in January. By comparison, the Midwest regional average score was 56.0, followed by the South with 51.3, the

Now that engineers have determined that a ruptured diaphragm plate led to the failure of a pair of cables on a 2,200-ft cable-stayed suspension bridge in Minneapolis, they are turning their attention to potential causes of the rupture, as well as fractures uncovered on two additional plates in late February. Photo Courtesy of the Minneapolis Department of Public Works The Martin Olav Sabo Bridge, a on a 2,200-ft cable-stayed structure bridge in Minneapolis, remains closed as investigators attempt to determine why a diaphragm plate supporting one its cables ruptured. Meantime, city officials say they are satisfied with results of an

Although U.S. construction employment hit a two-year high in January, it remains below peak levels in 329 out of 337 metro areas, including Chicago-Joliet-Naperville, Ill, where employment has declined by 35 percent since peaking at 187,200 jobs in 2001, according to data compiled by the Arlington, Va.-based Associated General Contractors of America (AGC). On a percentage basis, job losses in the Chicago-Joliet-Naperville area were the fourth worst in the nation, behind Phoenix-Mesa-Glendale, Ariz.; Riverside-San Bernardino-Ontario, Calif.; and Las Vegas-Paradise, Nev.Year-over-year data present a mixed picture for the Midwest, with Illinois, Ohio and Indiana showing employment gains from December 2010 to

Although average construction backlogs in the Midwest remained largely unchanged for the fourth quarter of 2011, backlogs slid 3.2% nationwide, from 8.1 months to 7.8 months, for the same period, according to Washington, D.C.-based Associated Builders and Contractors (ABC). Backlogs in middle states, including Ohio, Indiana, Illinois, Wisconsin and Missouri, rose from 6.22 months to 6.53 months between the third and fourth quarters, putting the region roughly on par with Western states, but well behind the Northeastern and Southern regions, whose backlogs for the fourth quarter averaged 7.99 months and 8.92 months, respectively.“The disparity between regional construction is on the

Overhead, an El train rumbles across Chicago's Devon-Sheridan viaduct. Below, amid cracks, spalls and exposed rebar, a network of strain gauges measures the amount of stress that has shifted from the original concrete structure to new supplementary steel shoring. Photo Courtesy of the Infrastructure Technology Institute Data culled from monitoring the structural performance of the Chicago Transit Authority's Devon-Sheridan viaduct will be used to develop models to predict the long-term performance of similar strucures. As the structure continues to deteriorate, primarily from exposure to deicing chemicals, the steel columns and their concrete footings are expected to absorb more of the

Overhead, an El train rumbles across Chicago's Devon-Sheridan viaduct. Below, amid cracks, spalls and exposed rebar, a network of strain gauges measures the amount of stress that has shifted from the original concrete structure to new supplementary steel shoring. As the structure continues to deteriorate, primarily from exposure to deicing chemicals, the steel columns and their concrete footings are expected to absorb more of the loading imposed by trains, the roadbed and the structure itself.The gauges measure the elastic movement of the steel columns each time a train crosses the overpass—as many as 450 times a day. The greater the

The Board of Water Commissioners for the Detroit Water and Sewerage Dept. says the contractors it recently suspended from bidding on department contracts due to “actions that have or may have caused [DWSD] economic or non-economic harm” will be allowed to appeal the decision, perhaps within weeks.However, water board Chairman James Fausone hasn't specified the nature of the information the board will require from the 13 firms, which are referenced in a 2010 federal indictment of former Detroit Mayor Kwame Kilpatrick (D); his father, Bernard Kilpatrick; DWSD contractor Bobby Ferguson and a former DWSD director, Victor Mercardo.On Jan. 5, one
