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.
Construction of a 290 metre long berthing line, with a depth of 16 metres against the zero calibration of the Port of Barcelona. The selected structural design consists of a dock of seven precast reinforced concrete caissons supported on a riprap foundation.
These caissons, and the ground underneath their foundation bed, will be used to assess the consolidation of the seabed during the construction of the dock.
A containment wall will be constructed perpendicular to the berthing line at its southern end. This containment wall consists of a sloping breakwater made up of different grades of riprap and delimits the perimeter area of the enclosure reclaimed from the sea that will be filled in to create the new esplanade.
Construction of the berthing line will require the sludge and clay from the seabed to be excavated and dredged to create a trench that will hold the foundation platform for the dock.
The structural design selected to extend the dock consists of seven precast reinforced concrete caissons, which are sunk to their final location and then filled with aggregate material.
Each caisson measures more than 40 metres long and weighs more than 8,000 tons. These have all been constructed by ACCIONA’s Kugira floating dock, one of the largest of its kind in the world.
- Location: Barcelona, Spain
- Acciona’s role: Construction
- Infrastructure: Alignment of the Muelle Adosado mole in the Port of Barcelona to create an additional 290-metre berthing line, 16 metres deep.
- Completion date: End of 2018
Kugira, el coloso artesano
La historia del ser humano discurre paralela al desarrollo de la navegación marítima. Desde el amanecer de los primeros pueblos eminentemente navegantes como los griegos, los fenicios o los vikingos, las civilizaciones antiguas expandieron sus fronteras náuticas aprovechando los refugios naturales que las ensenadas, las bahías o las grandes desembocaduras de los ríos ofrecían frente a las inclemencias de mares y océanos...
