Copasa is recognised internationally for its ability to build major infrastructures projects. Its experience, accumulated over more than 30 years’ history, makes it a leader in undertaking civil engineering and building.

The company has five specialised business units – Railways, Roads, Water works, Building and Ports.

Iron roads
Construction of infrastructure (platform) and superstructure (track laying) of conventional and high speed railway lines, maintenance of these lines, manufacture of sleepers and ballast; all these activities have been present in the company since its founding and give Copasa a notable railway character.
Our modern railway works machinery keeps us on the leading edge of technology in the sector, also forming one of the companies with the most complete and advanced fleets of machinery, giving us the capacity to be present in the most important railway maintenance and conservation contracts.

Copasa has participated in the construction and maintenance of Spanish railway infrastructures since its constitution. This recognised experience allows us to enjoy a leading position in the construction of both conventional and high speed railway lines that has culminated in the leading participation in the construction of the Mecca to Medina high speed line in Saudi Arabia.


Asphalt paths
The construction and conservation of roads and motorways has been one of the core activities of SA de Obras y Servicios, Copasa since its constitution in 1985, both in Spain and in other countries.

Bridges, viaducts and tunnels are a fundamental complement within this type of project. Copasa has wide experience in the construction of all types of unique structures with technologically advanced construction systems.

In tunnel boring, the company has built tunnels with diverse methods, both with traditional means and with latest-generation tunnel boring machines (TBMs). One notable example of tunnel construction that Copasa is undertaking now is that of the Rodoanel Mario Covas motorway tunnels in São Paulo, Brazil.  These are two parallel tunnels each with a cross section of 200 m2 and 1 km long, carrying four motorway lanes.

In the construction of bridges and viaducts, Copasa has a wide range of references of very diverse types and constructional systems.

Hidraulic works

The life of water

Supplies, integral sewerage, DWTPs, WWTPs – all these have been and continue to be present in the company’s projects portfolio. This interest in water works is supported with the acquisition by Copasa of Passavant España, now Pesa Medio Ambiente, a technology company specialising in water treatment.

As well as in Spain – where Copasa recently terminated two major waste water treatment plants, in  Burgos and Orense – the company is undertaking water works projects in Bulgaria, Romania, Peru, Brazil, Morocco and Algeria and it is also present in the operation and conservation of supply and sewerage systems and drinking water treatment plants (DWTP) and waste water treatment plants (WWTP).

Building construction

Urban creativity

Schools, university faculties and colleges, libraries, theatres and auditoriums, hospitals and health centres, sports stadiums, airport terminals and residential building; all form a constant in the wide career undertaken both in Spain and in South America with projects carried out in Mexico, Chile, Brazil and Peru.

Notable recently-terminated projects include the new La Portada stadium in La Serena, Chile, the new law courts building in Orense and the Jaén hospital in Peru.


Building in the sea

Copasa has been involved in the construction of major port works such as the new Punta Langosteira port in La Coruña, Spain, one of the most important maritime projects built in the last decade.

The company is currently undertaking the enlargement of one of the most important ports in South America, the Port of Veracruz, consisting of the construction of a new breakwater more then three kilometres long.
