INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
ACCIONA's experience in the construction of suburban lines is supported by its long and successful career in major Spanish and foreign cities, where in recent years it has carried out large-scale projects.
Most notable at national level is its contribution to the expansion of the Madrid metro, where the densely built-up urban environment has never ceased to present a complex challenge. ACCIONA has worked on the construction of over 48 km of the Madrid metropolitan line, along with almost 40 stations, on lines 2, 6, 7, 8, 9, 10, 12 and sections 1B, 1C and 2A of the Metronorte. A total of 31.5 km were executed using EPB tunnel boring machines, 11.5 km using conventional means and 5.5 km in a false tunnel.

The machine that even Jules Verne was unable to imagine
The technological evolution of tunneling machines, which accelerated at the end of the 19th Century and finally took off in the first half of the 20th, contributed greatly to the expansion of land transport worldwide. The excavation of tunnels to break through mountain ranges or circumvent difficult passes facilitated the ferrying by rail and road of passengers and freight, with their subsequent social and economic benefits...
