Although Marie Laveau no longer practices voodoo in New Orleans, another “dark art” —soils testing—is practiced there, under unprecedented scrutiny and at a higher level of intensity than ever before. “The work here is moving state of practice into state of the art,” says Dr. Rai Mehdiratta, program director for FFEB Geotechnical Consultants, a joint venture. He says the joint venture in the last two years has accomplished work that previously would have taken 15, “using more tools” in the process. “What we are doing here today, people will expect in the future,” he says.

California officials hope to soon begin holding public meetings to gather information for a sea-level-rise assessment report that Gov. Arnold Schwarzenegger (R) has asked the National Academy of Sciences to prepare by Dec. 1, 2010. But finding money for the contract is an issue.

Industry sources describe the funds provided in the final stimulus package for the environmental sector as a good start that could help the Obama administration meet its goal of jumpstarting the economy by creating and saving more jobs. But they acknowledge that the $20.6 billion allocated for environmental projects ranging from water and wastewater infrastructure to levees, Superfund and Dept. of Energy nuclear cleanup falls far short of what is needed to address current and long-term needs.

New Orleans’ hurricane and storm damage risk-reduction system is much improved since Hurricane Katrina, but protecting lives will continue to require an emphasis on evacuation, especially until 2011, when the 100-year protection levels are scheduled to be in place. The risk remains high. Photo: Angelle Bergeron Debris behind floodwalls are evidence the walls took the load as the water came over. Those are the findings of a reconnaissance team sponsored by the National Science Foundation, through the Geoengineering Extreme Events Reconnaissance Association. The team’s inspections last October assessed system performance in Hurricane Gustav’s Sept. 1 landfall. The team plans to
Not a day goes by that Walter Baumy, engineering division chief for the New Orleans District of the U.S. Army Corps of Engineers, doesn’t get a call or visit from someone who says he has a better mousetrap a better product or method for bringing the Greater New Orleans Hurricane and Storm Damage Risk Reduction System to 100-year levels by 2011. But since the district is now in an all-out push to meet that deadline by rapidly prosecuting designs and contracts in hand, Baumy is wary of the distractions.

Literally miles of pile will be installed in New Orleans over the next two years as the U.S. Army Corps of Engineers rushes to bring the area’s flood-control system to 100-year protection levels by June 1, 2011. As the largest civil-works project in the area’s history, it could be a very loud job. But so far it isn’t, thanks in part to a quiet hydraulic machine that area engineers are making some noise over. Initially, the Giken unit sits on a reaction stand. Later, it works atop existing pilings and uses them as counterweight. After driving a piling, the rig�s
Every fall, during low-water time on the Mississippi River, a crew of about 300 men and women turns out to resume one of the longest-running and most important construction projects of the U.S. Army Corps of Engineers—the placement of articulated concrete mattresses along the levees to prevent scour and protect communities. Slide Show Photo: Angelle Bergeron / ENR The operation requires a river of cable, fed up from below decks.

Following a dramatic accident—the second in two months on the $803-million Interstate 10 Twin Spans bridges project—lead contractor Boh Bros. Construction Co. is reviewing safety procedures and employee training and actively seeking out “any additional steps we can implement to improve safety,” says Robert Boh, company president. Photo: La. DOT New Orleans Twin Spans project suffered a second accident in two months on Dec. 23. The Dec. 23 accident occurred when a 20-year-veteran crane operator, working a mobile hydraulic crane, apparently made a lift “beyond the safe working radius of the crane, causing the machine to tip over against the
Work continues on the $803-million I-10 Twin Spans bridges in New Orleans despite a second accident by the lead contractor on the project in two months. A Boh Bros. Construction, New Orleans crane operator remains in the hospital in serious condition after falling 30 ft. from the bridge into Lake Pontchartrain Dec. 23 when his crane became unbalanced, eventually toppling into the water as well. "Our employee was operating a mobile hydraulic crane to move a steel roadway curb from into position on the north end of the project," says Robert Boh, company president. "For reasons as yet not fully
Shifting the emphasis of flood risk reduction work from structural, to non-structural efforts, such as better risk communications and improved evacuation planning, is a key recommendation the National Committee on Levee Safety will make in a report to Congress on Jan. 15. Photo: Tom Sawyer/ENR Emphasis would shift from work like this slurry wall construction to bolster levees in Sacramento to improved risk communications and evacuation planning. The levee failures in New Orleans after Hurricane Katrina sounded a national alarm on the unreliability of levees for flood protection, the committee concludes. It will recommend greater use of evacuations during periods
