Alberici Constructors, St. Louis, installed two 230-ton sector-gate leaves at the Seabrook Floodgate Complex in New Orleans on March 15 and 17.

By mid-March, only about 3,000 ft of a hardened, 123-mile-long storm-surge defensive ring around New Orleans remains to be closed.

With creative use of laser scanning, Alberici Constructors has shaved four weeks off its schedule to install two 120-ton steel vertical-lift gates that are part of a $165-million complex.

Making the decision to blow almost four miles of Mississippi River levee to operate the Birds Point-New Madrid floodway was one of the most difficult decisions of Maj. Gen. Michael Walsh's 34-year career as an Army officer.

It took teamwork to build the New York City Dept. of Environmental Protection's $1.4-billion, 2-billion-gallon-per-day Catskill/Delaware Ultraviolet Disinfection Facility—the world's largest—on time, on budget and with less than 2% change-order costs.

Emerging from the Mississippi River and Tributaries System's worst flood season in history, the U.S. Army Corps of Engineers and its contractors are gearing up to deliver $802 million worth of repair and reconstruction—more than three times the MR&T's annual operating budget—while continuing to battle ongoing fall and winter floods as well.

Following bid protests by losers of a $675-million flood control project in New Orleans that were upheld by the U.S. Government Accountability Office, the Army Corps of Engineers is seeking new bids from the contract’s original five short-listed teams. Some observers termed the move to re-procure the project as highly unusual and bidders are not saying how they will proceed.The move to re-bid will now push contract award for the Permanent Canal Closures and Pump stations (PCCP) to April 2012 and final project completion to October 2015, almost a year later than originally anticipated.The design-build contract was awarded in April

This work is worth an estimated $75.8 million, but the Corps wants to focus on the long term. Both the public and policymakers

If you want an early briefing of the U.S. Army Corps of Engineers’ new, National Levee Database, register soon because there are only 120 spaces available for each of three webinars that have been scheduled to introduce it, starting Oct. 27.The Corps is announcing public access to the NLD, a dynamic information source that provides, for the first time, map-based visualization and search capabilities for the location and condition of levee systems nationwide. Developed by engineers and scientists, it is said to have a "distinctly technical feel."  There will be at least two levels of access, one, will make available
