A400 celebrates 30 years of activity, marking three decades of a journey built through engineering, innovation, and people.
On August 31, 2025, A400 celebrated three decades of activity, a journey marked by landmark projects, continuous innovation, and a strong connection to the people who are part of its history.
Founded in 1995, A400 has grown alongside the engineering and construction sector in Portugal, establishing itself as a trusted partner in projects of high technical complexity and national and international relevance. Over these 30 years, it has consolidated an identity based on quality, innovation, and the appreciation of its teams.

Three decades also represent the evolution of a company that has kept pace with the sector’s transformation and the increasing complexity of projects. Throughout this journey, engineering has become increasingly integrated, requiring greater coordination between disciplines, the ability to anticipate needs, and a global vision for every design decision.
It is in this context that A400 has developed its activity, bringing together technical knowledge and different disciplines around a coordinated approach. The objective remains focused on the quality of solutions and the ability to respond to the challenges of each project, balancing performance, efficiency, constructability, and a close relationship between the different teams involved. This approach is aligned with A400’s current positioning of integrating and coordinating disciplines within a single structure.
In marking that A400 celebrates 30 years, this milestone also allows us to look at the evolution of the tools and methodologies that are now part of project development. Technology, digitalization, and collaborative processes play an increasingly relevant role, yet it remains the technical knowledge, experience, and decision-making capacity of the teams that provide consistency to the solutions developed.
A journey made of projects and people
The 30th-anniversary celebration brought together founders, employees, clients, partners, and family in a moment of recognition and sharing.
This human dimension has accompanied A400’s history since the beginning. Each project results from the contribution of different people, skills, and experiences, and it is these relationships, built over time, that help provide continuity to the company and the way it faces engineering challenges.
These 30 years are, therefore, an opportunity to recognize those who participated in this journey at different times: those who were at the company’s origin, those who contributed to its growth, those who currently work on projects, and those who, as clients or partners, trusted A400 to develop engineering solutions.
More than celebrating a date, this anniversary represents the sum of many stages, projects, decisions, and professional relationships that have helped build A400’s identity over three decades.
30 years with eyes on the future
More than just a date, 30 years represent a milestone of continuity. A400 renews its commitment to contributing to a more sustainable, efficient, and innovative sector, staying true to its mission: Building tomorrow, Today.
The experience accumulated over three decades forms a foundation to continue responding to new challenges. The evolution of the sector, sustainability requirements, digital transformation, and the growing need for integration between disciplines make project development increasingly demanding and reinforce the importance of combining knowledge, method, and adaptability.
In this new chapter, A400 intends to continue developing projects where engineering is conceived in an integrated way, seeking to anticipate constraints, improve processes, and transform complexity into technically coherent solutions prepared for the reality of construction.
