HISTORY

A400: a story of growth, continued success and a vision for the future

A400 was founded on 31 August 1995 by three founders. More than friendship, what united them was commitment, a desire to learn and a shared vision for the future of engineering. Three decades on, we are one of the leading engineering consultancies in Portugal, with active operations in Portugal and Angola.

We have turned challenges into opportunities and written our own chapter of innovation, developing the GPS (Synchronised Project Management) software and adopting the BIM methodology early on. The creation of our R&D and Sustainability departments strengthens our ability to anticipate the market and deliver integrated, responsible solutions.

Every achievement reflects the joint work of our teams and the values that define us. We continue to look ahead, underpinned by our working methodologies and by the certifications that validate our rigour.

Mission and Vision

For three decades, A400’s engineering has been built on two clear pillars: where we head every day, and where we want to arrive.

Mission

To transform the future with engineering, technology and sustainability.

Every project is an opportunity to apply what we know to solve real problems, with a lasting impact on people and on the territory.

Vision

To create value by offering innovative and sustainable solutions through a determined multidisciplinary team.

To be a market leader among engineering consultancies in Portugal and an international reference. It is an ambition we share with the entire A400 team, and one reflected in our working methodologies and certifications.
