Technical guarantee About us
Bim, Lean & Final Cut


Serom is actively committed to the use of new methodologies in all the projects it carries out.

The use of BIM methodology helps us to centralise all the information relating to the project in a single information model created collaboratively by all the agents involved, from the development phase to execution.

We apply the LEAN methodology to all construction projects, which allows us to detect potential problems and act from the root to ensure production and quality always optimal for our customers.

Finalcad software allows us to collaboratively manage our projects efficiently, integrating all participants in real time, increasing quality, saving time and reducing costs.

Serom continuously invests in the training of all staff in these methodologies to ensure the best implementation and use in all projects. The company is also a partner of the ITeC (Institute of Construction Technology), where all our construction teams are trained in Last Planner System, and actively collaborates with the European BIM Summit.
