HISTORY

Over 60 years opening the way underground

OSSA, Obras Subterráneas, was set up in 1952.

It was a difficult start in the demanding world of mining, at a time when manual labour received little help from machines.

But the entrepreneurial courage and tenacity of the founders provided OSSA with the culture, infrastructure, human resources and optimal mechanical methods so that the company would grow over more than 50 years to become the current leader in the underground works sector in the Iberian peninsula.


BACKGROUND
1952 Founded in Asturias (northern Spain), originally dedicated to mining (galleries and shafts)
- Imprtant mining areas: Almadén, Iberian Pyrite Belt in Huelva, Linares and Suria
1958 OSSA began hydraulic work
- Projects: Hydroelectric Plants in Miranda, Conso, Toga; Nuclear Power Plant in Cofrentes, etc.
1975 As a result of the downturn in Spanish mining, OSSA diversified its activity into the construction of road and rail tunnels
1985-2008 The company focussed its activity on roads and railways throughout Spain, working on major infrastructure development projects in Spain
- Road tunnels: Guadarrama, Cadí, Negrón, Piqueras etc.
- Railway tunnels: high-speed network AVE (e.g. Pajares, San Pedro, Ontígola etc.)

2008 Historically OSSA had been a 100% family owned company with the Figar family as the sole shareholder from 2005
