Renovation of M3 metro line, Budapest, Hungary
SWIETELSKY Építő Kft. was contracted by BKV Zrt. (Budapest public transport corporation) to renovate the central section of the M3 metro line (9 metro stations). The metro line, built between 1976 and 1990, is currently one of the most important Hungarian infrastructure projects. The works include in particular the integration of special constructions and systems, such as inclined lifts, escalators and ventilation systems. A particular challenge lies in the organisation of the construction works and the supply of materials to the underground stations in the city centre, in particularly cramped conditions. Works are planned to last from November 2019 to December 2022.
