📋 Tender Overview
The modern machinery only needs to excavate the Plaza Bolognesi station to finish stage 1B of the railway project. The tunnel boring machine Delia successfully crossed the Central Station (E-13) of Line 2 of the Lima and Callao Metro, in a full-pass mode, completing the excavation of the tunnel at this important stop, reported the Ministry of Transport and Communications (MTC), through the Urban Transport Authority for Lima and Callao (ATU).
The institution explained that civil works will continue at the aforementioned station, then it will move on to the architectural stage. Meanwhile, the tunnel will be implemented with the railway system.
The tunnel boring machine Delia, named in honor of Delia Tasaico del Pino, the first female mining engineer in Peru, is now heading to the Plaza Bolognesi station (E-12), where it will complete the tunnel of Stage 1B of the railway project.
However, its work will not end in this area. The tunnel boring machine will continue its excavation work in Stage 2 and the stations it will visit are: Parque Murillo (E-11), Tingo Maria (E-10), La Alborada (E-09), Elio (E-08), San Marcos (E-07), Oscar Benavides (E-06), Carmen de la Legua (E-05), until finally reaching the Insurgentes station (E-04).
Construction work on the Central Station began on July 7. Previously, the ATU implemented a vehicular diversion plan in the vicinity of Plaza Miguel Grau, Paseo Colon and Av. Garcilaso de la Vega.
It should be remembered that Delia began drilling at the Central Station after the MTC and the concessionaire Metro de Lima Linea 2 S.A. signed an addendum that allowed the tunnel boring machine to pass through said station prior to its construction.
To date, 18 km of tunnel have been built on Line 2. From the Municipalidad de Ate Station (E-27) to the San Juan de Dios Station (E-19) there are 8 km of tunnel built with the traditional NATM method or New Austrian Method.
While from the San Juan de Dios E-19 station to the Central station (E-13) there are 6 km of tunnel built with the Delia tunnel boring machine; and from the Insurgentes station (E-04) to the Port of Callao (E-01), there are 4 more km of tunnel, the latter excavated with the Micaela tunnel boring machine.
