ARCADIS ANNOUNCES $85 MILLION IN U.S. ARMY CONTRACTS

ARNHEM, The Netherlands—October 1, 2003—ARCADIS G&M Inc., a subsidiary of ARCADIS NV (NASDAQ: ARCAF, EURONEXT: ARCAD), announced today that it has been selected by the Northern Region Contracting Center (NRCC) and the U.S. Army Environmental Center (USAEC) to execute three of its Guaranteed Fixed Price Remediation contracts for Ft. Jackson, in Columbia, South Carolina; the Sierra Army Depot in Herlong, California; and the Lake City Army Ammunition Plant in Jackson County, Missouri. The contracts will be part of ARCADIS' Guaranteed Remediation Program (GRiP®). The total contract amount for all three contracts is more than $85 million.

Our substantial experience and ongoing leadership in the GRiP® market has positioned us well to provide this innovative support to our government clients.
