Within underground works in hydroelectric power plants, some of the largest and most difficult projects are the large-scale caverns designed to house large, high-price generator equipment. Such equipment requires locations of large dimensions and maximum quality.

Besides being the most spectacular part of the plants, these caverns are the structures that require the highest degree of specialization because of the difficulty in the construction stage.
Hydroelectric power plants also need a set of complementary works of special characteristics: conduits, diversions and restorations, which involve enormous construction variety depending on the diameter, section type, longitudes and terrain.

OSSA has carried out projects for excavation, support and concrete work many tunnels and shafts with different characteristics, while complying with the quality requirements and deadlines specified by our clients.
