ARCADIS Logos Wins US$ 80 Million Contract for Samarco Pelletizing Plant Project

ARNHEM, The Netherlands, May 21, 2010 - ARCADIS (EURONEXT: ARCAD), the international consultancy, design,
engineering and management services company, announced today that its
affiliated company in Brazil, ARCADIS Logos, has signed a US$ 80 million
contract with Samarco, a company owned by VALE and BHP, to provide project
management services for the realization of a pelletizing plant project (the
P4P project). With a total investment of about US$ 2.8 billion, the project
aims to increase the installed capacity of the Ubu Pelletizing Complex up to
30 million tons per year.

The P4P project comprises the construction of a new iron ore plant, in
the state of Minas Gerais, and a new pelletizing plant integrated into an
iron ore stockyard, in the state of Espirito Santo. The two sites will be
linked by a pipeline with a total length of 400 km, as part of the P4P
project. The project will be implemented in two phases with a total duration
of almost four years. The first phase, from May to December 2010, will focus
on the consolidation of the feasibility studies and will represent
approximately 5% of the total contract value. The start of the second phase
is conditional to approval by the shareholders (VALE and BHP) in December
2010. The second phase will entail implementation of the project and is
expected to be completed by December 2013 with the start-up of the
pelletizing operation. ARCADIS Logos will provide project management and
consulting services for Samarco with a team of approximately 230 people on
four job sites.

"Our long term experience in managing projects in the mining sector and
our performance during the implementation of the Samarco 3rd pelletizing
project are the main reasons for ARCADIS Logos to be chosen for this
prestigious assignment. The contract gives continuity to our long term
successful partnership with Samarco and reinforces the good relationship
between ARCADIS Logos and its customers." said Manoel Antonio A. Avelino da
Silva, CEO of ARCADIS Logos.
