PRESS RELEASE 23 Nov 2005

JAAKKO PÖYRY GROUP PARTICIPATES IN ENGINEERING OF THE E18 MUURLA-LOHJA MOTORWAY


JP-Suoraplan Oy and JP-Transplan Oy, which are part of the Jaakko Pöyry Group's Infrastructure & Environment business group, are members of the consulting joint venture assigned by the Skanska Tekra Oy and Lemcon Oy consortium (TYL E18) to provide engineering services for the Muurla-Lohja motorway project. The value of JP-Suoraplan's and JP-Transplan's assignment is about EUR 4 million.

The consulting joint venture of JP-Suoraplan, JP-Transplan, Ramboll Finland Oy and Sito Oy shall provide construction-phase engineering services for the road, bridges and tunnels, including geotechnical engineering. The project comprises a 51-km road section with 76 bridges, eight interchanges and some five kilometres of twin tunnels. Optimisation of construction and maintenance costs will be the consulting group's objective in preparing the technical solutions.

Special attention will be given to environmental issues in the construction by adjusting the motorway to the landscape and by tunnelling it where necessary. Traffic safety is another main issue in the design. This section of the E18 between Muurla and Lohja completes the motorway between Turku and Helsinki. It is a major improvement to the traffic connections between the European Union and Russia, especially St. Petersburg.

The project will be implemented using the life-cycle model, a Finnish application of the public private partnership (PPP) model. Based on the service agreement between the Finnish Road Administration and Tieyhtiö Ykköstie Oy, Ykköstie has engaged TYL E18 for the engineering, construction and maintenance work. In the life-cycle model, the investment is paid only when the road is taken into use, which is an economical solution also for taxpayers. Furthermore, this model makes it possible to open the road for traffic in 2008, one year earlier than originally planned.

The shareholders of Tieyhtiö Ykköstie Oy are Skanska Infrastructure Development AB, Laing Roads Ltd and Lemminkäinen Oyj.

The Jaakko Pöyry Group's Infrastructure & Environment business group uses the brand name Jaakko Pöyry Infra. Its net sales for 2004 were EUR 142 million. The business group has offices in 25 countries and employs 2000 experts worldwide.
