The work to expand the commercial dock facilities of the Port of Ushuaia in the Argentine province of Tierra del Fuego, Antarctica and the South Atlantic Islands, aims to extend the current mooring front by approximately 80 meters, including the execution of a new 20-meter dolphin, which will create an additional logistics area of 2,400 square meters. The works also involve installing new lighting and energy supply facilities, as well as water services and the provision and placement of bollards and fenders.

The project will increase the pier’s docking front capacity, envisaging the expansion of operations to enable the port to handle a greater number of tourist, cargo, fishing and scientific vessels at the same time, freeing up its logistics capabilities and operating capacity. This also means that larger vessels will be able to berth, permitting big cruise ships to visit and driving the development of tourism and trade in the province.

The structural typology of the dock extension involves building seven transverse frames made up of four reinforced concrete piles of 1.50 meters in diameter, and a beam or transverse head to support the longitudinal pre-cast reinforced concrete beams and prefabricated pre-slabs. These are linked by a layer of compression cast concrete "in situ", responsible for creating the structural rigidity required by the project.

The dolphin or mooring massif has been planned as a structure supported by four piles similar to those used for the quay, and the massif will be built upon these using pre-cast reinforced concrete shells as formwork and final internal "in situ" casting. The execution of the piles will be carried out from a self-lifting floating platform.
