ARCADIS Aqumen Signs Frame Contract With BT for Facility Management Services

ARNHEM, The Netherlands, June 28, 2010 - ARCADIS (EURONEXT: ARCAD), the international design, consulting,
engineering and management services company, announced today that its
subsidiary ARCADIS AQUMEN FACILITY MANAGEMENT (AAFM) has signed a three-year
framework contract to provide services to BT (former British Telecom) in the
Benelux. AAFM is a joint venture of ARCADIS and U.K. based Carillion. The
contract provides a good platform for the further internationalization of the
activities of AAFM, while at the same time it strengthens the firm's position
in the Benelux market.

Under the contract AAFM will provide an integral package of facility
management services for all the office locations of BT in the Netherlands,
Belgium and Luxemburg. Upon a successful implementation in the Benelux, this
contract will also open an opportunity to broaden the scope to other BT
entities in Europe. To do so, AAFM and BT will closely align their strategies
for real estate management services, with consistency and transparency as
main starting points for the cooperation.

"We see a growing demand from international corporations looking for
pan-European solutions for management of their facilities. This allows AAFM
to introduce economies of scale to create more cost savings for its clients
while at the same time focusing on the quality of the services provided,"
said Bernt Bouwmeester, director of AAFM. "This contract will certainly
contribute to the growth of our business in 2010."

ARCADIS AQUMEN has been a facility management service provider since
2002.
