The major project came into use in September 2020 covering the highly populated neighbourhood of Drumul Taberei, with an estimated traffic of approximately 50,000 people who will use the metro each day.
Bucharest is the largest city in the country, with a population of almost 2.5 million people. Confronted with serious traffic issues, the management of the city is trying to expand the subterranean infrastructure, this being the fastest way of transiting the city today. During 1979–2013, four lines were built, with 51 stations and 70km of double lane. However, since the boom in housing construction on the outskirts of the city, the need to expand has become fairly urgent.
Holcim Romania was chosen to be part of the project and contributes by offering products and solutions for building concrete structures, delivering hundreds of thousands of usual and special concrete using 2, 3 or 4 concrete plants. Holcim also delivered tens of thousands of cement tonnes for in-deep consolidation of soils, through jet-grouting technologies providing additional services like on site stock management, laboratory services and technical support.
Holcim Romania states: "The project took place in challenging conditions, in an open and intense traffic. Even so, we managed to show maximum flexibility throughout the project, producing and delivering products and services 24 hours a day, even during the winter.
"An important role in the completion of this project was played by Holcim Technical Centre in Romania, which carried out the study for raw materials and concrete recipes, monitoring the elements' heat of hydration, constantly offering technical consultancy."
