Arcadis Wins Large Water Management Contract in Brazil

AMSTERDAM, January 21 - ARCADIS (EURONEXT: ARCAD), the international consultancy, design,
engineering and management services company, announced today that ARCADIS
Logos in Brazil, in a consortium with a local firm, has signed a large water
management contract with the Brazilian Ministry of National Integration for
the implementation of the Sao Francisco River Integration Project. The total
amount of the awarded contract is US$ 42 million, ARCADIS Logos' share
amounts to US$ 21 million.

The project aims to reduce the chronic water shortage in the northeastern
part of Brazil. Work will include the construction of two channels of in
total 720 km, complemented by aqueducts, tunnels and reservoirs. This will
result in up to 127 m3 of water per second to be pumped from the Sao
Francisco River up to the arid basins, establishing a reliable source of
drinking water with seasonal surpluses destined for irrigation.

ARCADIS Logos' management and technical support includes the general
coordination, time and cost planning and control, procurement, engineering
supervision, environmental coordination and auditing of the construction
quality control activities performed by third parties. This contract is an
extension of an earlier contract, resulting in continuity of services from
ARCADIS Logos, and its partner, since the project started in 2005.

Project completion is scheduled for 2012, requiring a total investment of
US$ 3.4 billion. Some 12 million people living in the arid regions will
benefit from it. The project is being developed across 4 Brazilian states and
will generate 9,100 jobs during construction. A comprehensive environmental
program complements the project, including archeological site rescue efforts,
deployment of water and sewerage systems in neighboring communities and life
improvement for native Indians and small communities.

"This unique project in size, importance and complexity provides an
excellent platform to demonstrate the breadth of strong capabilities we have
within ARCADIS Logos. We will continue to offer our client integrated
services that will enable a rapid, yet high quality implementation of this
important project", said Manoel da Silva, ARCADIS Logos' CEO.
