the company

Techint Engineering and Construction has more than 60 years of experience in Chile in EPC, Construction Management and Maintenance services across a range of market segments including Mining, Power, Oil & Gas, Infrastructure and Industrial.

Mining has been one of the most significant markets for Techint E&C in Chile. The company designs and/or builds facilities for this industry, including mineral processing plants, water conveying systems (pipeline and pumping stations) and slurry pipelines including choke stations, as well as providing processing plant maintenance services.

It is not only involved in the construction of these projects, but also right from the early stages, cooperating in feasibility studies and basic and detail engineering, in which its constructing experience applied to engineering, constitutes an added value for clients.

In every project it gets involved in, Techint E&C complies with the highest safety standards while protecting the environment and promoting development of the communities it operates in.

Techint E&C began its activities in Chile in 1952, when the country’s national oil corporation, ENAP, awarded the construction of a maritime terminal and mooring system for the Cerro Manantiales-Caleta Clarencia oil pipeline to the company.

Since then, the company has built for the Mining and Oil & Gas market segments, the majority of the country’s main duct projects, including major pumping systems and concentrate ducts for diverse mining operations, the Trans-Andean oil pipeline, and the Northern Andes and Gas Andes natural gas pipelines.
