The works to extend the Muelle Adosado of the Port of Barcelona, carried out by ACCIONA Construction in a joint venture with the company Copcisa, are now 80% complete.
This project, with a budget of €28.3 million, consists of extending the existing Muelle Adosado dock by building an additional berthing line measuring 290 metres long and 16 metres deep. Once completed, this work will make it possible to expand the facilities of the adjacent container terminal, specialised in general freight and containers, or for use as a mooring area for cruise ships in the medium-to-long term.
The structure chosen to expand the dock consists of seven prefabricated reinforced concrete caissons, which have already been placed in their final position and filled with aggregate.
Each caisson measures over 40 metres long and weighs more than 8,000 tonnes. They were built with ACCIONA Construction's Kugira floating dock, one of the largest of its kind in the world.
The Kugira can manufacture caissons in excess of 66 metres long, 32 wide and 34 high, reducing construction time considerably. The environmental impact is also lower than other more traditional methods.
Over the coming months, the maritime dumping works will take place corresponding to the backfill of the caissons, the area bulkhead and general filling, until the dock expansion work is complete, which is expected by the end of this year.
ACCIONA Construction is a global leader in major port works with caisson technology. In the last decade, it has participated in the construction of over 14 km of breakwaters, 10 km of docks and 18 million m3 of dredging in different countries.
