Founding and Regional growth

OAS’ path starts with civil construction, and since the beginning the company has had quality, responsibility and ethics as pillars of the services it provides. Coupling professional competence with engagement the Company promptly wins reliance and is faced with new challenges, contributing directly to the growth of the area where it operates in Brazil.

A period marked by work diversification in the civil construction segments (private and public customers), real estate developments (residential and commercial), in addition to a strong acting in the agro industry area in Bahia and in other Northeast states.

Qualified growth and OAS International

This was a period of greater interests in state-owned investments, particularly in the oil, gas, and power areas, in works entailed to the Federal Government’s structural programs and in major privately owned companies. The international area goes through a strong growth, quickly adapting to the dynamics and different Brazilian legislations. The projects from this period encompass highways connecting cities in Bolivia, sanitation works in Chile, gas distribution network in Montevideo (Uruguay), among other infrastructure projects.
