The maximum $50M (£24.5M) contract is the second given to the international consultancy and engineering company for work at the city, stricken by flooding in the wake of Hurricane Katrina during August 2005.
This time, Arcadis will provide general design support services, multidisciplinary consultancy services and construction management services, for the New Orleans District of the U.S. Army Corps of Engineers.
Work will include the evaluation, design and construction management of levees and floodwalls, coastal restoration, special structures for flood protection as well as major pumping facilities. Work also encompasses development, evaluation and planning studies for improved levels of flood protection for New Orleans and portions of south Louisiana.
The contract was won by a joint venture of Arcadis and Bioengineering Group also involving partners HNTB, WL Delft Hydraulics and Arcadis subsidiary Alkyon.
The contract includes a base period of one year and four option periods of one year each.
"We see this second large contract award as an important expansion of our presence as a flood protection and water resources consultant in the United States, which is fully in line with our strategy of becoming a leading player in flood protection and water management services globally," said Arcadis chief executive officer, Harrie Noy.
He added: "With increasing worries about the impact of climate change, we expect a growing demand for our extensive water management experience. We are looking to expand our water management involvement in Florida and California, where we feel our flood management know-how can be of great value".
