PROJECT BOOKPROJECT BOOKOver 65 years opening the way underground
PRESENTATIONOSSA, founded in 1952, is a leading company in the underground construction sector specializing in three business
areas: Construction, Energy and Mining.
Both in underground excavations by traditional method (NATM), as well as in tunneling with TBM, and roadheader mining,
OSSA is a solid underground works partner for important industrial and construction groups internationally. At OSSA
we are highly commited to Quality, Health and safety, and Environment, and we invest in Research and Development
Projects at an international level. We promote a culture of respect and teamwork among our team.
OSSA has vast recent experience both in high speed railway tunnels with over 60 km of high speed rail tunneling projects
in the last five years, leading the Spanish market in this specialty, and also in underground power plants, having built
over fifteen underground plants with some of the largest underground caverns in the world. As a recent highlight, we are
participating in the design and construction of the Hong Kong to Shangai High Speed Rail Line.
Internationally OSSA has executed works in Hong Kong, Taiwan, Chile, Peru, Colombia, Panama, Costa Rica, Brasil and
Nicaragua and is recently focusing its tendering activity in North America, Central America, Asia, Canada and Great Britain.
After 65 years of success, our strategy is to continue expanding internationally, and to support large civil engineering and
mining industry clients at all levels, contributing our vast technical expertise and our equipment fleet, while prioritizing
health and safety and innovation in all our projects.
SAFETYSafety is Obras Subterraneas, S.A.’s main asset from the time when its operations begin, demanded by the specialisation
required for the works carried out underground.
The company’s staff have a high degree of professionalism and specialisation, which has been achieved after many years
of training and the transfer of know how. Working in confined spaces with the presence of gas, dust, noise, low visibility
and the use of explosives means that the Obras Subterraneas, S.A.’s security department is the most relevant in the
company.
The use of cutting-edge, innovative techniques in the field of underground works requires the continuous training of the
company’s human resources.

The Project is being carried out inside the facilities of the Andean Division (DAND) of CODELCO (Chile), located in the high and central part of the Andes mountain range, in the 5th (Valparaíso) Region, 50 km northeast of Santiago, currently working the Río Blanco (copper) mining deposits. The scope of this contract involves construction of the underground works for the Transfer Project, the object of which is to ensure (and even increase) production at the mine until 2022.The works to be carried out mainly comprise the following:
• Excavation and reinforcement by drill and blast of:• Haulage Tunnel III (4,833 m) which connects Sector 3,500 with the Cordillera Plant Sector• Tunnels, access and ventilation galleries, caverns and shafts (using raise boring) in Sector 3,500 and in the Cordillera Plant Sector• Draw points for fire protection and pedestrian shelters
• Contruction of:• Construction window portals• Paving of Haulage Tunnel III• Installation of the geomechanical monitoring system

The work involves the execution of two parallel tunnels for air injection for the future Chuquicamata mine. The tunnels are of approximately 4,320 m each and a gauge, or thickness of 10.74 x 8 m2, with an incline of more than 14%. Both tunnels are connected by way of three passages each of 27 m and a gauge of 7.65 x 5.60m2.
Support elements used: reinforced concrete, resin bolts of 3, 4 and 6 m in length, wire mesh 150 x 150 x 7.5 mm, TH-21, TH-36 and HEB 200 trusses and forepoling.
