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.
The $780-million project consisted of the construction of a railway line for trains with a speed of 350 km/h, including two tunnels of 15 km and 13 km in length and 8.50 m inner diameter with connecting tunnels every 250 m.
Half of each tunnel tube was excavated using two double-shield TBMs.
The project includes infrastructure, superstructure, civil works for railway installations, replacement of utilities and services, environmental integration, non-railway installations and ancillary works.
