A profound transition of the trades and the sector

Today’s stakeholders are obliged to comply with numerous environmental standards. These are necessary for the sake of human welfare, but they still represent additional constraints for which solutions must be found.
These new challenges must now be incorporated into an environmental conservation approach: Preserving biodiversity, designing sites differently, reducing environmental impact, etc.

Our expertise is based on our human capital and our CAD facilities. Over the last 25 years, SEIMAF has acquired solid experience through its involvement in many projects covering issues relating to the treatment of water, air and fumes.

Our teams can provide the support you need in accordance with your technical and financial requirements.

Project Manager

I have been a general installation “project management” engineer for 5 years now. The wide variety of projects I have worked on in different industrial sectors, as well as the technical challenges to be overcome, have allowed me to develop at every stage and to continue improving my design and project management skills within projects.
