ARCADIS EXPANDS ACTIVITIES IN BELGIUM

ARNHEM, The Netherlands, September 18, 2003—ARCADIS (Nasdaq: ARCAF; Euronext: ARCAD), the international consulting and engineering firm, today announced that it has acquired two Belgian firms: engineering consultancy FALLY-DELBAR-JOUNIAUX NV (FALLY) and facility management consultant DOMUS NITIDA (DOMUS). Financial details about these acquisitions were not disclosed. Both companies will become part of ARCADIS Belgium, ARCADIS' subsidiary in Belgium, which with 450 employees is one of the top three consulting engineers in the Belgian market.

FALLY has its headquarters in Charleroi. With annual revenues of € 2.5 million and 30 employees, FALLY is one of the largest privately owned engineering firms in the Walloon provinces of Belgium. The company designs buildings, with a specialization in the design of hospitals. In addition, FALLY is active in the market for infrastructure, including, among others, water treatment installations.

For ARCADIS, this acquisition provides access to the Walloon region, which offers attractive growth opportunities in infrastructure as well as environmental activities. FALLY will gain access to the full knowledge and service potential of ARCADIS, thereby further strengthening its position in its market.

Headquartered in Turnhout, DOMUS has annual revenues of € 1 million and 10 employees. The firm specializes in consulting in the area of facility management for buildings. Using proprietary software and standardized measuring methodologies, DOMUS optimizes the budgets, organization and quality of certain aspects of building management.

This acquisition represents an important step for ARCADIS in the Belgian market for facility management. DOMUS will be able to further expand its position by using ARCADIS' technical know-how and client contacts.

Harrie Noy, Chief Executive Officer of ARCADIS said: "With these acquisitions we strengthen our position in the Belgian market. FALLY provides access to the Walloon provinces, an interesting market with considerable growth potential where they have a strong position. Based on our cooperation on the expansion project for the Charleroi airport, we know that FALLY's culture and activities are a good fit with ours. DOMUS is active in facility management, which we have earmarked as a strategic growth segment. The experience and expertise DOMUS has in this field is an excellent addition that strengthens our existing range of services in Belgium."
