ARCADIS Subsidiary RTKL Wins Design for Large Shanghai Medical Complex

361,000 m2 Medical Center Will be Largest Single-Phase Hospital Development in China

ARNHEM, The Netherlands, March 8, 2010 - ARCADIS (EURONEXT: ARCAD), the international design,
consulting, engineering and management services company, announced that its
subsidiary RTKL has been selected to design the Shanghai Changzheng New
Pudong Hospital. This will be the largest new hospital built in one phase in
China. The 2,200-bed facility will comprise 361,000 m2 (3.9 million SF) with
an estimated construction cost of RMB 2.82 billion (US $413 million).
Construction is scheduled to begin later this year.

"This is a significant win for us," said ARCADIS CEO Harrie Noy. "It not
only strengthens our presence in China but confirms the trend toward the
globalization of healthcare, which offers broader opportunities for ARCADIS.
There is a premium on knowledgeable healthcare design in countries that have
a growing consumer demand for quality service and sustainable environments.
ARCADIS is responding to that demand."

RTKL was selected through an international design competition in which
more than 30 architecture firms participated. According to Xingdong Zheng,
the hospital's president, "RTKL's design was an exceptional response to our
goal of creating a modern academic hospital that will be internationally
recognized for excellence in patient care, research, and teaching. The design
supports patient-centered service as well as our desire for an
environmentally friendly medical center."

"RTKL's design for the new Shanghai Changzheng Pudong Hospital
capitalizes on China's increasingly sophisticated healthcare consumer," said
RTKL Executive Vice President Brad Barker, who directs the firm's healthcare
sector. "Our client challenged us to create a world-class hospital to serve a
population that has come to demand-and expect-advanced healthcare facilities,
patient-focused care and the latest technology-all within an environmentally
friendly facility."

The 2,200-bed hospital will include four inpatient towers, a VIP tower,
an outpatient center, an emergency center, and an infectious disease
building. Beyond patient care components, plans also include research and
teaching facilities, dormitories for students and staff, an administration
building, and a conference and reception facility.

RTKL will provide master planning and design services for the project,
with Shanghai Municipal Architecture Design Institute as a local partner
handling the construction documentation. The international architecture and
design practice has a long tradition of work in China and throughout Asia,
including the design of the Shanghai Science and Technology Museum; City
Crossing mixed-use development in Shenzhen; the Beijing Museum of Film; and
the Shenzhen Literature and Arts Centre, among other.
