Cesar Mata Pires was born in 1950 in the northeast Brazilian city of Salvador, the son of a wealthy cattle rancher. While studying civil engineering at the Federal University of Bahia, he landed an internship at construction company Odebrecht by showing up one day and pressing for a job. He joined Odebrecht colleague Carlos Suarez and founded construction and engineering company Olivieri, Araujo, Suarez & Engenheiros Associados in 1976. Araujo is Mata Pires’s mother’s maiden name.

Their first jobs were subcontracted from Odebrecht, today Brazil’s largest construction firm. One of them was for a marine outfall, a pipeline that shoots waste water deep into the sea where pathogens die off faster. The project caught the attention of Antonio Carlos Magalhaes, who was about to begin his second stint as governor for the state of Bahia. The billionaire met and married Magalhaes’s daughter Tereza during those years, and as the politician rose up through the country's military dictatorship he pushed business to his son-in-law’s company. Magalhaes became head of the Senate after the return of Brazilian democracy in 1985.

OAS projects have included Sao Paulo's iconic Estaiada Octavio Frias de Oliveira bridge, whose cables reach to a mast height of 138 meters (453 feet), as well as 4,600 kilometers (2,858 miles) of highways, two of the 12 stadiums used in the 2014 World Cup, and subway lines in Rio de Janeiro. It also expanded Sao Paulo's Guarulhos international airport.

After Magalhaes died in 2007, OAS pushed abroad, working on projects throughout Latin America, Africa and the Middle East. Mata Pires's son Antonio Carlos, named for his father-in-law, is vice president OAS's investment arm and his other son, Cesar Mata Pires Jr., holds the same post at the flagship construction division. His daughter is not involved in the family business.
