Integrity
01We act with ethics, transparency and respect in every commercial, professional and institutional relationship.
Grupo JAF began in construction, in Guimarães, and has built a business structure present across essential sectors. We have grown on experience, closeness to operations and a long-term view.
Technical experience, business vision and delivery capability.
Since 1999 we have built a track record grounded in rigour, responsibility and the ability to adapt. We diversified from accumulated experience, from spotting new opportunities and from building capabilities able to create long-term value.




Each value translates into concrete behaviour. They are not banners: they are decision criteria applied when assessing projects, partnerships and results.
We act with ethics, transparency and respect in every commercial, professional and institutional relationship.
We plan, deliver and review with technical demand, attention to detail and a commitment to quality.
We stand by our commitments, by the impact of our decisions and by the results.
We value collaboration, shared knowledge, cohesion and a sense of belonging.
We look for solutions that are more efficient, safer and better suited to how markets and needs evolve.
We build environmental, social and governance criteria into management, operations and investment.
We started in Guimarães, with construction as the point of departure. The experience gained on site and in maintenance built the technical and commercial base that let us move step by step into new areas of activity.
