E-mail dcv@pch.etat.lu 05/08.The Luxembourg public works ministry has awarded Wayss & Freytag Ingenieurbau and Galère, both operating companies of Dutch building group Royal BAM, Max Boegl, Félix Giorgetti and Tralux, a EUR88.2 million contract (VAT not included) to construct the Stafelter tunnel. Royal BAM has a 75% share of the contract. The tunnel is 1,850 m long, consisting of two separate tubes connected by six cross-passages. It is the last tunnel on the Route du Nord A7 motorway between Luxembourg City and Mersch. The tunnel crosses Luxembourg sandstone at 30-40 metres above the water table so that the groundwater will not be affected by the tunnel. The tunnel will be constructed mainly using the drill and blast method and excavator locally. The choice of the supports will depend on the rock class that is encountered. Construction will take four years to complete. The safety equipment is not part of the contract and will be tendered separately.
