The history of QUADRANTE GROUP begins when the Engineers João Silveira Costa, Nuno Pais Costa and Nuno Batista Martins get together in 1998. Later, they were joined by Engineer Tiago Pais Costa. At that moment we began to take the first steps. Ambitious, but always solid and confident steps.

Our Founding Partners have been working together since the time when they attended Instituto Superior Técnico and they started their professional careers as a team. After a few years designing and coordinating large-scale and complex projects in Portugal and Asia, they founded QUADRANTE GROUP. 

The continued trust placed by the oldest clients, whom QUADRANTE GROUP is proud to continue serving, as well as the attraction of new clients, and the implementation of an acquisition and market concentration policy, allowed us to gain a prominent position in the domestic market and to be considered as a benchmark company. We are the largest Engineering and Architecture Consulting firm whose capital stock is entirely Portuguese. Several years have passed and we have grown, advancing successfully into the future. We were bold and fearless. Guided by the will to innovate and to reach even further, we have built a strong and mature identity. We have achieved a prominent position through our clients and a performance guided by our commitment to efficiency. We are proud of this position, which has allowed us to Design. Create Value
