ARCADIS Introduces New Structure and Appoints Presidents for U.S. Operations

ARCADIS (EURONEXT: ARCAD), the international consulting, design and engineering company, today announced it has introduced a division structure for its U.S. operations, in order to get better aligned with key clients and markets as well as the global capabilities of ARCADIS. With this new organization, the integration with Blasland, Bouck and Lee (BBL), which was acquired as per October 2005, has been finalized. BBL has now been integrated into the new Environmental division and its operations are continued under the ARCADIS brand. The environmental division will be led by Gary Coates, who has been appointed President of this division and by Ed Lynch, former president of BBL, who will serve as Operations Director for the division. Gary Coates joined ARCADIS in 1989, as business development director and was its Chief Operating Officer since January 2005. Bob Goldman, former CEO of BBL, was appointed ARCADIS global director for Environment in early 2007. The activities related to transportation, water resources and land development are concentrated into the new Infrastructure division, headed by Mike Caroll, who has been appointed President of this division, with Dave Thomas as the Operations Director. Mike Caroll has served as Executive Vice President in several regional management positions in ARCADIS since 2001. Also the project and construction management services of Pinnacle One, acquired in November 2006, and of earlier acquired CDG will be part of the Infrastructure Division, under the leadership of Chuck Dahill, former CEO of Pinnacle One. RTKL, the world leading architectural design and planning firm that joined ARCADIS as of July 2007, represents ARCADIS building division in the U.S. and continues to operate separately. In total ARCADIS has about 4,600 people in the U.S., generating some 1 billion US$ in revenues. "With the new organization we have changed from a regional structure to a divisional structure, allowing us to increase client focus and to use our resources more efficiently”, said Steve Blake, CEO for the U.S. operations of ARCADIS. "We are pleased BBL has successfully been integrated. By combining the best of both worlds we have built an organization with a strong client focus, outstanding project management and technical capabilities and an excellent team of people. Last year this has resulted in very strong organic growth and higher margins, especially in our environmental business. With our ability to deliver high quality services seamlessly, both in the U.S. but also internationally to multinational clients, we can continue to gain market share. Now the infrastructure activities are combined in one division, we are better positioned for continued growth in that field, also through acquisitions. By achieving synergies between the different activities we can deliver a full service package to our clients,” Mr. Blake concludes. ARCADIS is an international company providing consultancy, design, engineering and management services in infrastructure, environment and facilities, to enhance mobility, sustainability and quality of life. ARCADIS develops, designs, implements, maintains and operates projects for companies and governments.
