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.
Rookwood Weir is a mass concrete structure with fixed crest spillway, stilling basin, left and right abutments, low flow outlet, and dedicated fish and turtle passage solutions. Situated on the Fitzroy River, 66km south-west of Rockhampton, Queensland, the structure rises 16.2m above the riverbed and has a full supply volume of 74,325 megalitres.
The construction of an innovative fish lock with multiple entry and exit levels will allow for increased fish passage as head- and tail-waters fluctuate on the Fitzroy River. Also, Rookwood's dedicated turtle passage has been specifically designed to cater for the movement patterns of the Fitzroy River Turtle and White-throated Snapping Turtle, allowing for safe, 24/7 navigation of the waterway barrier.
300,000m3 of excavation volumes have been saved by optimising the weir crest length and batter slope design. This resulted in 4,427 tonnes of cement being saved through the Project.
