Construction on Panama's New Underground Metro System 10% Advanced

The Executive Secretary of the Metro, Roberto Roy, said the first tunnel boring machine "Marta" will come to Panama in October. It will start working at the "Southern Trench" near Albrook. The second TBM named "Carolina" will start work at the "Northern Trench" on Via Transístimica. Roy said the TBM "Marta" will start work in December and the second in January 2012. "So far the work has gone well, and the project has been advanced by 10%. Probably this month they will surpass 15%," Roy told local media. Roy also announced that within weeks they will begin the work of removing utilities to make way for the construction of the underground Metro station to be located at the Church of El Carmen on Via España. Roy made his statements as the inauguration of the plant that will be producing the "dovelas" or ring segments. These segments, made of precast reinforced concrete, are bolted together to form a conical-shaped ring to support the walls of the tunnel carved out by the TBMs. (Panama America)
