ARCADIS TO PERFORM PROJECT MANAGEMENT FOR THE EXPANSION OF THE LARGEST AIRPORT IN BRAZIL

September 18, 2012 - ARCADIS (EURONEXT: ARCAD), a leading international consultancy, design, engineering and management services company, today announced that its Brazilian subsidiary ARCADIS Logos has signed a contract to provide project management (PM) consultancy services for 27 months, for the first phase of the expansion of the Guarulhos Airport, in São Paulo. Guarulhos is the largest airport in Brazil with 25 million passengers per year. The expansion project is part of the infrastructure investment program launched by the Brazilian Federal Government to cope with the increasing passenger demand, now boosted by the two upcoming major sports events: the 2014 World Cup and the 2016 Olympic Games.

The client is the private company Concessionária do Aeroporto Internacional de Guarulhos S.A. that is owned by private investors (51%) and the state-owned company Infraero (49%), which formed after the recent competition for the airport concession. The first phase of the R$3 billion project is scheduled to be accomplished by the beginning of 2014 and comprises building a new terminal - increasing the airport's total handling capacity from the current 30 million to 60 million passengers per year - and improving parking lots, runways, yards and access roads. During this phase, ARCADIS Logos will be responsible for Planning, Procurement, Construction Supervision, Executive Design Certification, Quality Control, Health & Safety and Environmental Control.

At the peak of activities, a team of 50 ARCADIS professionals will work at the jobsite. ARCADIS Logos will also count on the expertise of professionals from ARCADIS group company EC Harris, to support the project with its expertise on Built Asset Consultancy.

"This contract is a new milestone in the prosperous and continuous development of ARCADIS presence in Brazil, creating the opportunity for ARCADIS Logos to introduce the concept of Built Asset Consultancy in Brazil that EC Harris successfully applied at Heathrow Airport in London. Regardless of the upcoming 2014 World Cup and the 2016 Olympic Games, airports are crucial infrastructure investments in Brazil and ARCADIS Logos is proud to have once again an opportunity to play a major role in realizing such investments", said Manoel Antonio Avelino da Silva, CEO of ARCADIS Logos.
