Brazil is enjoying today one of its most promising phases, with international events such as the World Cup in 2014 and the Olympic Games in 2016, and the economic stable scenario. At the same time, the country is facing the need for massive investments in infrastructure, whether to ensure the growth of its economy, or to improve the degree of social development of the population, which is becoming more and more urban. In this scenario, the implementation of large projects arises, such as the Belo Monte hydropower plant, the high speed train linking Rio de Janeiro-Sao Paulo-Campinas (TAV), transposition of the Sao Francisco river, investments in Pre-Salt and urban mobility works, mainly in large cities. The tunneling industry was very busy in 2011 in Brazil, especially with respect to the construction of hydroelectric power plants, with underground hydraulic schemes. Most of those belong to private investors. It is also important to mention that Petrobras (The Brazilian Petroleum Company) has definitely moved towards tunnelling as a solution to underpass environmental protection areas. Underground mass transit systems have continued in major cities such as Brasilia, Rio de Janeiro and Sao Paulo. The bid for the construction of the 15-km long São Paulo’s Metrô Line 5 was in 2011. Design of Line 6 is expected to be bid in 2012. The City of Sao Paulo is about to launch the bid for construction of the Roberto Marinho urban highway tunnel, underneath a 3-km long urban park to be created as part of the actions for urban rehabilitation of an area in the Southern part of the City, coupled with real estate investments. The work will consist of two parallel, 3-lane, 2.7- km long tunnels. The bid for construction and concession of the 520-km long Campinas – Sao Paulo – Rio de Janeiro high speed rail line is scheduled for September 2012. The total underground length of the line will be in the range of 110km to be constructed by TBM and conventional tunneling. Other important cities are preparing underground mass transit systems to start their bidding processes in 2012, like Curitiba, Belo Horizonte and Porto Alegre.
