This should take until mid-November, after which the tunnel will be inspected. The project has been held up since 9th June, 2000 when pressurized water and mud started to invade the tunnel while jet grouting was under way. Immediately, settlements affected the Praí§a do Comércio area and traffic was cut to heavy vehicles. Evacuation of the personnel was ordered. The 800 m tunnel was sealed between the Arsenal and Santa Apolí³nia shafts. As water ingress continued to flood the tunnel, it was decided to flood it completely to avoid soil liquefaction and further damage to surface buildings. Further studies were ordered and the project was altered. A team of Dutch specialists has been hired to help resume the project. Work completion has been set for end-2003. Metropaí§o, a consortium including Teixeira Duarte, Opca and Mota & Companhia, is responsible for construction. 37/02.The ACE JV formed by Somague, BPC, Engil, Spie and SBES will be using a refurbished Lovat EPB TBM to construct a 1.5 km Red Line extension, running east to west between Alameda and Sao Sebastiao.
