ARNHEM, The Netherlands, October 2 /PRNewswire/ --     ARCADIS (EURONEXT: ARCAD), the international consultancy and engineering
company, has been awarded a second contract for flood protection work in New
Orleans. 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 (Corps). 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 size is a maximum of US$50 million, which includes a base
period of one year and four option periods of one year each. It is the second
time the U.S. Army Corps has awarded a contract involving forward-looking
design services for hurricane protection in the Gulf Coast. Earlier this year
the joint venture of ARCADIS and Bioengineering Group was already awarded a
five year US$150 million framework contract for the same type of services.

"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 Harrie Noy,
Chief Executive Officer of ARCADIS. 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."

Project 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 southern Louisiana.
