PHOTO COURTESY OF NeW YORK DEP The $800-million New York City portion of the new City Tunnel No. 3 supply line is designed to provide redundancy for an aging system. Regardless of size, location and system configuration, most of the water and wastewater utilities in the U.S. share a common attribute: the continuing need to upgrade and improve their treatment facilities and underground infrastructure.Though the sluggish post-recession economy has largely removed capacity expansion from the list of priorities, there remains no shortage of needs on utilities' to-do lists.Most often, the driver is meeting federal discharge mandates, as is the case
Cracks in 13 cast-in-place pier caps supporting three bridges on the new Intercounty Connector toll highway in Maryland may be the result of a design flaw, according to the Maryland State Highway Administration.More than 40 cracks—ranging in width from 0.005 to 0.035 in. and in length from 7 in. to 3 ft, 8 in.—were discovered during a routine MSHA close-out and acceptance inspection of the ICC's $2.56-billion, 7.2-mile first phase.The project's first-phase contractor is Intercounty Constructors, a joint venture of Granite Construction Co., Watsonville, Calif.; Corman Construction Inc., Annapolis Junction, Md.; and G.A. & F.C.

The magnitude-5.8 earthquake that rattled most of the eastern U.S. on Aug. 25 created new cracks and spalling in the upper sections of the 555-ft, 5-in.-tall Washington Monument in the nation's capital. While the extent of quake-related damage was not a surprise, the size of several spalls was larger than expected, says a forensic engineer who conducted an inspection for the U.S. National Park Service.The survey team of Wiss, Janney, Elstner Associates Inc., Northbrook, Ill., extracted any spalls that represented a potential fall hazard

That paraphrasing of the familiar adage sums up the mood of contractors regarding the water and wastewater infrastructure market. With expansion and upgrade projects in many parts of the country curbed by anemic economic growth and cutbacks in government spending, the market is now focused on helping clients keep their aging systems one step ahead of both time and tightening water-quality mandates.Pat McCann, CEO of Weston

That thoroughfare carries approximately 110,000 vehicles each day along one of Seattle’s primary north-south arteries. Damage from the 2001 Nisqually Earthquake sparked
At a time when cutbacks threaten surface transportation programs across the U.S., a new economic analysis from the American Society of Civil Engineers says that simply maintaining current levels of investment won't be enough to avert long-term losses in productivity, jobs and household income.Drawing on widely used transportation planning models and consumer and industry data, “Failure to Act: The Economic Impact of Current Investment Trends in Surface Transportation,” forecasts that, within the next decade, the added costs of dealing with deteriorating highways, bridges and transit systems will result in the loss of more than 870,000 jobs and cut the nation's
BridgesThe North Carolina Dept. of Transportation is proceeding with a complex replacement of the Herbert C. Bonner Bridge on the Outer Banks, despite a new lawsuit that claims the project violates the National Environmental Policy Act.PCL Civil Constructors Inc. and HDR Engineering Inc. of the Carolinas submitted the apparent winning bid of $215,777,000 for the design-build project that NCDOT estimated would cost approximately $241.6 million.Replacing the deteriorating 2.7-mile, 260-span prestressed-concrete girder structure across Oregon Inlet has long been a top priority. It is the only highway link to Hatteras Island, one of the state's most popular tourist destinations and home
Some skilled equipment operators have a sixth sense that allows them to focus on the task at hand while maintaining awareness of the bustling, often unpredictable activity going on around them. Unfortunately, no operator has yet developed X-ray vision that allows a viewpoint through engine cowlings, cab framing and other obstructions.

Over the past fifty years, construction management has evolved from its role as the owner's liaison with prime contractors to its new role of coordinating the technical and functional dynamics of complex building programs within any one of an “ever-hybridizing” array of delivery methods. So it is no surprise that a “one size fits all” approach to CM has gone the way of steam shovels.“Today, one size fits one,” says Blake V. Peck, president and chief operating officer of Fairfax, Va.-based construction management firm McDonough Bolyard Peck Inc. (MBP). “Every owner, every project is different, and the construction manager has
