Construtora Andrade Gutierrez / Camargo Corrêa Consortium
Selection of technology and elaboration of Final design of the Permanent Route of Lot 3 of Line 5 - Lilac of the São Paulo Metro, with 5,075.5 m of extension, being formed by two simple routes in parallel tunnels, resulting, therefore, in 10,151 m tunnel track. The track gauge is 1,435 mm and the rails used have profile 60-E1, with resilient attachments. The superstructure of the permanent way uses the mass-spring system, which is a damping system that prevents the vibrations and secondary noise induced by the passage of the trains in the track reach levels above the allowable, thus preserving the comfort of the residents. 849.71 m of access roads were also projected on raised paving slab.
