Who We Are

OAS was set up in 1976, in the State of Bahia, operating in the engineering and infrastructure area. It is, today, a privately-owned Brazilian multinational conglomerate, which gathers companies present in the national territory and in a lot of others countries. Relying with thousand of employees, it is a benchmark in entrepreneurship, safety and quality. Today, OAS has established itself in two supplementary areas: OAS Engenharia S.A., responsible for carrying out heavy-duty civil construction works in the private and public sectors, such as highways, airports, hydroelectric power plants, dams and ports, and OAS Investimentos S.A., focused on investments in infrastructure, sanitation, multipurpose arenas, oil and gas, concessions of urban roads, highways, subways and airports. The Company's format allows it to serve both private and public customers, concessions and PPPs (private public partnerships). OAS has quickly increased its activities abroad, with major structuring works such as the Baba Hydroelectric Power Plant in Ecuador, and the Potosi-Uyuni highway, in Bolivia, among others. Its presence, in Brazil, is decisive in essential areas for the Country's development, such as water resources, power and urban infrastructure, airports and ports, further relying on a strong growth of the mass transport in the states of São Paulo and Rio de Janeiro.
