Business & Technology Editors

ARNHEM, The Netherlands--(BUSINESS WIRE)--Sept. 23, 2002

ARCADIS (NASDAQ: ARCAF; Euronext: ARCAD), the international knowledge based services provider in infrastructure, buildings, environment and communications, and Aqumen, one of the UK's leading suppliers of facilities management and support services, today announced that they are joining forces to create a new Joint Venture (JV), ARCADIS AQUMEN FM.

Based at Arnhem in Holland, ARCADIS AQUMEN FM will initially operate in the Netherlands, but it is envisaged that the company will develop a pan-European presence for its services in the next couple of years. ARCADIS AQUMEN FM will be unique combination in the Dutch market in delivering a total facility management solution for its clients.

The two joint venture partners have complementary skills that make for an extremely good fit. ARCADIS has a strong blue-chip client base in the Netherlands where it provides multi-disciplinary project management capabilities. Aqumen has a proven track record in delivering high quality facility management services to a wide range of public and private sector clients in the UK.

ARCADIS AQUMEN FM's principal offering will enable clients to enhance their performance and reduce costs - most notably in their non-core property holdings - through partnership. The new company will particularly address the needs of firms seeking trans-national facilities management solutions.

ARCADIS AQUMEN FM offers a range of delivery options: Total Facility Management, whereby ARCADIS AQUMEN FM contracts directly with the client to deliver a comprehensive range of services; Managing Agent, in which some or all of the client's existing service providers are managed; Partnering, where ARCADIS AQUMEN FM provides its own managers at various levels within the client's FM structure; and Consultancy, on a short or long-term basis.

Commenting on the launch of the new JV, Jack McGrory, Aqumen Managing Director said: "ARCADIS AQUMEN FM not only becomes the leading facility management provider in the Netherlands, but also a major player on the wider European facility management scene. The joint venture brings particular expertise in the delivery of Total Facility Management packages that not only relieve the client of the day-to-day demands of running their own support services, but also ensure that those services are fully integrated and consistent with core business objectives."
