Inner Harbor Navigation Canal (IHNC)
Surge Barrier Project
Shaw is leading the largest design-build civil works project ever awarded by the U.S. Army Corps of Engineers. A massive floodwall, which is part of the IHNC Surge Barrier Project, will provide 100-year storm-surge protection for the greater New Orleans area when completed.
During Hurricane Katrina in 2005, a surge entering the confluence of the Mississippi River Gulf Outlet and the Gulf Intracoastal Waterway overtopped and collapsed a 4,000-foot-long section of floodwall along the Industrial Canal. This caused widespread flooding in New Orleans and surrounding areas.
Shaw is providing project management, design and construction services for a massive, two-mile surge barrier floodwall and three flood gates designed to block hurricane storm surges from entering the Industrial Canal. The wall will be constructed of 1,271 concrete cylinder piles 66 inches in diameter, 144 feet long and driven to 130 feet. Shaw used internal resources from one of our fabrication shops in Louisiana, completing placement of the piles making up the majority of the floodwall on Oct. 21, 2009, only five months after the first pile was driven.
