en.Wedoany.com Reported - The Buenos Aires City Government in Argentina has announced that the bid opening for the Metro Line F project has been postponed from April 22nd to July 14th. This adjustment was made primarily due to bidders' requests for an extension of the preparation period. Concurrently, some companies pointed out that the existing tender documents still require further refinement in terms of scope definition and technical data to support the calculation of project quantities. Meanwhile, supporting works for the construction of Line F, financing arrangements, and related legislative procedures are advancing in parallel. During the expression of interest phase, 22 companies worldwide expressed their intention to participate, including five Chinese enterprises: CRRC, PowerChina, China Machinery Engineering Corporation (CMEC), China Railway Group Limited, and China Civil Engineering Construction Corporation (CCECC).
According to the existing arrangement, this tender for Buenos Aires Metro Line F covers the engineering design, construction, and equipment configuration of the line, but excludes rolling stock, signaling systems, and communication equipment. These components will be implemented through separate subsequent contracts. The project plan is based on the existing design work completed by the UPU and the IATASA-ATEC consortium. Regarding core equipment, Metro Line F plans to procure 14 new train sets and adopt a new generation of automatic train control signaling systems.
The Buenos Aires City Government has initiated the tendering process for renovation works related to the Constitution Square transfer hub. The scope includes the relocation of bus dispatch yards, optimization of station layouts, and expansion of pedestrian spaces to create conditions for the future construction of Line F stations and entrances. Furthermore, the city government has submitted two bills to the legislative body: one seeks approval for up to $1.35 billion in financing for the project construction; the other deals with land acquisition arrangements for station entrances and ancillary facilities. The latter bill also proposes amending current laws to separate the Buenos Aires Metro Company (Subterráneos de Buenos Aires S.E.) from the new line construction process, removing its responsibilities for initiating tenders and supervising the engineering of Lines F, G, H, and I.
Buenos Aires Metro Line F has a total length of approximately 9.8 kilometers, connecting the Barracas district in the south of the city with the Palermo district in the north. It will have 12 stations, 8 of which will be interchange stations, enabling connections with existing metro lines and the regional rail network. In the future, Line F also has the possibility of being extended southward to the California station. Due to the area's proximity to the Riachuelo River and unsuitable geological conditions for tunnel excavation, the extension section is planned to be constructed as a viaduct. Official documents indicate that upon completion, this line is expected to become one of the metro lines with the highest passenger demand locally and will drive a redistribution of ground public transport passenger flows across the city.
The alignment of Buenos Aires Metro Line F was established as early as 2001 through relevant legislation and was confirmed again in 2008. Although the project has been mentioned multiple times over the years, progress has been limited. A tender for preliminary studies was launched in 2019 but was canceled in 2022 after multiple postponements, with the related studies subsequently completed internally by the Buenos Aires Metro Company. Following this, the project lacked substantial progress until the mayor announced last year its revival and advancement.
