ACCIONA was recognised at the awards ceremony for the Potencia Awards for Public Works Machinery and Civil Engineering on 7 November for two iconic projects, the Site-C project in Canada and the Roskilde Fjord Highway in Denmark.
These awards recognise the quality and effort of participants in Spain’s public works sector, both equipment suppliers and construction and engineering firms, as well as their capacity to innovate and their commitment to sustainability.
Jesús Cerrato, manager of the Concrete and Aggregates Plant of ACCIONA’s Self-Performing Office, collected the award in the Works category for the Site-C project that is currently ongoing in Canada.
Pablo Fernández, Head of Construction, collected the award in the Highways category for the Roskilde Fjord Highway in Denmark, which was opened recently.
Pilar Blanco, Technical Director of ACCIONA’s Roads and Bridges unit, also attended the awards ceremony on behalf of the company.
The ceremony to present the 2019 Potencia Awards for Public Works Machinery and Civil Engineering was held at the Santiago Bernabéu Football Stadium and was attended by over 200 professionals from the construction industry and public works machinery manufacturers and distributors.
This edition of the Potencia Awards included new categories in response to current trends in the sector, such as sustainability, innovation and research. The jury, which was once again made up of machinery fleet managers from the largest construction companies in the country and representatives from leading associations in the sector, chose the most outstanding projects for the awards.
Site-C Dam and Hydroelectric Plant (British Columbia, Canada)
The Site-C project consists of constructing an earthfill dam measuring 1,050 metres long and 60 metres tall on the Peace River in north-west British Columbia, Canada. It is part of an energy project for a 1,100 MW hydroelectric plant, one of the largest infrastructure projects in the country.
To support the hydroelectric plant and the spillway, also included in the project, ACCIONA will build a 70-metre tall foundation structure made from roller-compacted concrete with a total volume of 1.8 million m3.
In addition to the main public works contract, the project includes major ancillary works such as construction of 5 km of cofferdams and two river diversion tunnels that are 800 metres long and almost 11 metres in diameter, as well as various temporary access roads and bridges.
Once complete, Site-C will be the third dam and hydroelectric plant on the Peace River, as well as one of the largest dams in Canada. When it comes into operation, it will ensure a supply of clean and renewable energy for over 100 years to an average of 450,000 homes, generating a major boost for economic development and job creation in the region.
Roskilde Fjord Highway (Denmark)
Recently opened, this project was awarded to ACCIONA and its two partners in October 2016. It involved the design and construction of a four-lane (two in each direction) toll highway covering 8.2 km. The project included a concrete bridge spanning 1.36 km over Roskilde Fjord between the Danish towns of Marbaekvej and Torslev Hage.
This bridge, called the Crown Princess Mary Bridge, was built using the progressive cantilever system, launching precast beams. The foundations consist of 52 piles measuring up to 50 metres in length and two metres in diameter. A total of 492 precast elements were used in its construction using a system of joined segments weighing around 100 tonnes each.
In addition to the Crown Princess Mary Bridge, the highway includes 11 smaller structures such as bridges, wildlife crossings and cycle lanes, as well as one kilometre of retaining wall and a three-kilometre acoustic barrier.
The social and environmental requirements were one of the top priorities on the project, as the highway crosses various protected areas, including a zone that is part of the EU’s Natura 2000 network and home to some of Europe’s most valued and threatened species.
