Linha Universidade concession company and its main associate Acciona have opened segment lining ring factory that will manufacture the concrete segments to construct the tunnels of the Metro Line 6 project of the São Paulo Metro (Brazil). It will manufacture more than 60,000 new segments to construct the line, which is expected to open in 2025.

Located in a quarry in the district of Perus (São Paulo), the segment factory spans an area of 40,000 m2 and is close to major highways such as the Rodoanel, Rodovia dos Bandeirantes and Marginal Tietê. The unit has a production capacity of 15 rings per day, equivalent to 27 meters of the tunnel. Nine segments are required to complete each lining ring, and more than 60,000 segments will be manufactured to complete the works.

The first segments have already been successfully transported. The first tunnel boring machine, which will excavate towards the south, began operating on 16 December and will construct the 10 km section between the stations of Santa Marina and São Joaquim. The second tunnel boring machine will come into service at a later stage and will construct 5.3 km of the tunnel through rock in a northerly direction towards the future Brasilândia station.
