Project Summary

IMS provided structural design guidance and construction phase services for a nearly one mile long, 14 feet high concrete T-Wall which separates the East Bank Wastewater Treatment Plant from the Mississippi River.  The project was needed as a result of Hurricane Katrina’s damage.

The wall consists of three flood gates for the protection of the plant and is one of the largest such walls not designed and constructed by the U.S. Army Corps of Engineers. The wall is also one of the largest construction projects completed in New Orleans Lower Ninth Ward and offers the best protection from flood waters in the history of the plant.

Key features of the project included: ,1400 steel or precast concrete piles, three flood gates, reconstruction of an access road to the plant and also a perimeter access road for other projects to the north of the plant.

The design required coordination of specialized sub-consultants and working with various State and Federal agencies to obtain permits. IMS’ responsibilities extend through all phase of design, bidding, and construction.
