RAILWAY

OSSA, founded in 1952, is a leading company in the underground construction sector specializing in four business areas:

Construction, Energy, Mining and Services.

Both in underground excavations by traditional method (NATM) and in tunneling with TBM, 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 in high speed railway tunnels with over 75 km of high speed rail tunneling projects,

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 have built more than 10 km

of tunnels for the Santiago de Chile Metro.

Internationally OSSA has executed works in Hong Kong, Taiwan, Chile, Peru, Colombia, Panama, Costa Rica, Brasil and

Guatemala and is recently focusing its tendering activity in North America, Central America, Asia 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.

PRESENTATION

SAFETYSafety is OSSA’s main asset from the time when its operations began, 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 OSSA’s safety 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 works consist of the execution of the track bed for the High Speed Madrid-Galicia line, comprising 4.96 km of double track and 1.44 km of single track. The main works carried out were two viaducts: Requejo, with a length of 2.1 km; Los Pedregales, at 1.42 km. In addition the Pedralba de la Pradería Tunnel has been executed in the double-track section, with a length of 1,700 m including the false tunnels (1,580 m of bored tunnel) and an open cross-section of 86 m2. The Requejo Tunnel has also been executed, 2.4 km in length, for single track, with a cross-section of 75 m2, and including the construction of two false tunnels of 20 m each at the entrance and exit and another of 40 m in the middle. The excavation process for the tunnels follows the principles of the the New Austrian Method (NATM). Areas where the terrain is of high resistance have been excavated by drill and blast and those where it is of poorer quality with mechanical excavation.

The tunnels have cross-sections of 85 and 90 m2. The excavation was carried out using the New Austrian Method. Explosives were used in the geologically favourable areas and mechanical equipment in the more unfavourable areas.

Work involved the construction of a downhill entrance gallery with a 6.2% slope and 5,466 m in length. Besides the excavation of two parallel tunnels of 4,166 m and 3,189 m in length and 56 m² gauge, a cavern of 107 m in length and 426 m² gauge was undertaken. All these works belong to the León-Asturias high-speed line.Except for the tunnels that were excavated with TBM, the other galleries were drilled & blasted.To cover the parallel tunnels, 600 and 500 mm reinforced-concrete ring segments measuring 1.5 m in length were used, placed on 6+1 rings.Given the nature of the site and the size of the gallery, an in-depth pre-analysis of the site was undertaken.The main works were: 1,072,922 m3 of tunnel excavation, 39,945 m3 of cavern excavation, 79,512 m3 of varying-gauge gallery excavation, 14,365 m³ of steel fibre reinforced concrete, 122,216 ml of 32 mm-diameter bolts, 101,333 ml of 22 m fibreglass bolts, 124,027 ml of Swellex MN12 rockbolts, 3,500 ml of cable bolts, 1,032,700 kg of TH and HEB trusses and 69,115 ml of fibreglass-bolted covers.

The main project consisted of the excavation and support for the double-track Beasain Tunnel, with a linear length of 1,916 m and an open cross-section of 85 m2. The tunnel has been built by the conventional method, with blasting in areas of sound rock and using a backhoe loader in those where the terrain is of poorer quality, using the construction principles of the New Austrian Method (NATM). The main support elements used were: shotcrete, 25 mm diameter rock bolts, type HEB-180 trusses, 150x150x6 mm mesh, and steel tube micropiles.
