As part of the ARCADIS and Bioengineering Group joint venture, HNTB led design work for the pump facilities of the West Closure Complex Structure, one of the largest, most complicated components of the Greater New Orleans Hurricane and Storm Damage Reduction System.
The system includes levees, floodwalls, sluice gates, the country’s largest sector gate and the world’s largest interior drainage pump station.
Congress appropriated funds to upgrade the New Orleans system to 100-year protection levels following Hurricanes Katrina and Rita.
The HNTB team completed a planning study of alternatives under consideration, assessed pump types and placement, designed the pump station, provided engineering and quality assurance services, and oversaw quality control during construction.
The team also proposed cost-saving measures for the fast-paced project when the U.S. Army Corps of Engineers realized project costs might surge beyond authorized funding.
- Crucial pump facilities bring 100-year protection to New Orleans
- Cost-saving recommendations keep project within budget
