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.
SUSTAINABLE CITIES AND COMMUNITIES
Make cities and human settlements inclusive, safe, resilient and sustainable
Today, cities represent 3 % of the planet's surface and concentrate more than 50 % of the population. A figure that will rise to 70 % by 2050. In addition, cities generate more than 80 % of the world's gross domestic product (GDP).
In addition to facilitating access to essential services for life - such as energy and water - ACCIONA contributes to making cities places of productive well-being in which to live, favouring people's socio-economic development.
More than 3.8 kilometres of breakwater, 2.8 km of which will be made artificially using concrete blocks.
The terminal, which required 21,000 tonnes of steel and 350,000 m3 of concrete, was built using the technology of the Kugira, the world's largest floating caisson dock, owned by ACCIONA, which arrived in Brazil for the first time in 2011, exclusively for this project. The terminal is the first to be built with precast concrete caissons in Brazil. A total of 2,800 metres of protective dikes have been built, using Kugira's concrete caisson technology. A total of 42 floating caissons have been used.
The use of this technology to build the breakwater has led to a reduction of 8.5 million tonnes of stones in the rockfill. It has also avoided the emission of 100 tonnes of CO2.
ACCIONA's Engineering Business Line developed the engineering for the basic project and the construction project, as well as providing technical assistance during the execution of the works.
