COMPANY POLICY

RJ Ingeniería S.A. was founded with the purpose of being a construction company for engineering, hydraulic, sanitation, architectural, civil, and road works, as well as oil and mining services.

Since its foundation and over its more than 40 years of trajectory, it has paved the way for innovation both in the region and in the projects developed beyond it. Recognized for its quality, commitment to fulfilling contracts, and the high sense of belonging of its human capital, it is always driven by the challenge of executing complex works and motivated by the pride of completing them.

Our integrated management system is implemented under ISO 9001:2015 for Quality, ISO 14001:2015 for Environment, and ISO 45001:2018 for Occupational Health and Safety.

The company's origins date back to June 6, 1977, when Engineer René Alberto Retamal Jara founded RETAMAL JARA EMPRESA CONSTRUCTORA. From the beginning, the company was characterized by its rapid positioning in the construction sector in the Patagonian region, building a reputation for seriousness and professionalism.

Over the years, R.J. Ingeniería S.A. has diversified and expanded the types of projects it participates in. Initially specializing in basic infrastructure and road construction, it later expanded into energy and hydrocarbon exploitation projects. Today, the company develops urban infrastructure and sustainability projects, integrating innovative technologies to optimize resources and protect the environment.

With more than 48 years of experience in Patagonia, R.J. Ingeniería S.A. continues to grow and evolve, consolidating itself in the market as a leader in complex engineering and construction projects, with a firm commitment to innovation, quality, and sustainable development.


A company is the result of a group of people coming together to achieve a goal, but it is also the legacy initiated by an individual with a philosophy of excellence. Our company is composed of professionals committed to delivering comprehensive engineering and construction services, working as a team, and supervising all projects. Our organizational structure facilitates project leadership with an assigned responsible party, supported by the expertise of all professionals within the company, enabling us to respond to challenges in a multidisciplinary, agile, and effective manner.
