The origins of Semaica date back to 1956, when visionary civil engineers Gonzalo Sevilla Naranjo and Ernesto Martínez Cobo decided to build more than just infrastructure — they set out to build a legacy of excellence.

After completing their studies in the United States, they returned to Quito, Ecuador, driven by the belief that great engineering must rest on strong values: Respect for the client, Operational efficiency, Reinvestment for sustainable growth, Commitment to our people.

What began as a modest engineering firm evolved over more than seven decades into a diversified multinational group, trusted for its technical expertise, integrity, and long-term vision.
