en.Wedoany.com Reported - The Madrid Region has allocated €104 million (approximately $118.6 million) for the equipment installation and operation contract for the first phase of the extension of Metro Line 11.
The contract price is 15% lower than the tender base price of €123 million. This contract is independent of the underground civil works and is responsible for the installation of electrical and safety facilities in the tunnel sections, including the overhead catenary system and the integrated fire protection system. The works also include vertical transportation and passenger circulation systems at stations, involving 29 elevators and 60 escalators, as well as other auxiliary works.
This contract supports the construction of the Plaza Elíptica–Conde de Casal section, which spans 6.7 kilometers. According to reports, overall progress on the first section has exceeded 45%, and it is still planned to be operational by 2027. Excavation progress at various station pits varies: Comillas station is at approximately 60%, Madrid Río station at about 58%, and construction continues at interchange stations such as Atocha, Palos de la Frontera, and Conde de Casal.
In terms of tunnel boring, after the tunnel boring machine named Mayrit reached the interface, the two excavation faces between Comillas and Madrid Río were connected, technically referred to as a "cale." This connection completed the tunnel link between the two points, passing under the M-30 highway and the Manzanares River. The Madrid Region stated that this event marks one of the most significant milestones since construction began, coinciding with the project's "midpoint."
Since starting operations on March 26, Mayrit has advanced 1,116 meters, accounting for 21% of the planned route, and has installed 656 rings forming the permanent tunnel lining. The machine advances an average of 15 meters per day, sometimes reaching 30 meters. ACCIONA stated that its joint venture with Dragados and Rover has completed the excavation of the Comillas–Madrid Río section, advancing 1,114 meters in 75 days at an average of 15 meters per day, passing under the area surrounding the Manzanares River and the M-30 ring road to reach the future Madrid Río station.
The Madrid Region noted that the Line 11 extension aims to create a diagonal metro line, improving connections between neighborhoods and new urban developments, reducing travel times, and minimizing transfers. The project is expected to help alleviate congestion on Line 6, particularly on the Plaza Elíptica to Avenida de América section. The entire project began in November 2022 and is scheduled for completion in 2027.
