employees see their work as their hobby; they do it with pleasure. Passion results in high productivity, engagement, and loyalty. How proud we should be if it can be said that our company radiates Passion from all levels. It is a guarantee for success. It is also remarkable how important it is for employees themselves to conduct their work with Passion. For most employees, this is more important than the financial reward. Of course, salary is also important, but nice work that you can completely immerse yourself in is what makes the difference. This edition of Ivormatie again presents a series of projects on which several colleagues have worked with dedication. How wonderful is it to talk about the work you do at the office at home, such as projects for Nutricia or Vitens, the developments in wind energy at sea and the digital transformation we are currently busy with.

with composite steel deck floors has been applied, and the existing walls are connected to the new floors. The challenge here was aligning the new structure with the existing piles (creating straight lines downwards). But as discovered with the existing structure, this did not always work out well, which resulted in more complex transfers. The new structure and the archive drawings were therefore drawn up and calculated in a 3D model. Ultimately, the solution was found in a transfer structure that connected the new structure to the existing piles and adhered to the architect’s layout.

WHAT MAKES IV SO SPECIAL? Friendly and open culture
Down to earth
Iv feels like a family business: you can always drop by other colleagues to discuss your ideas. You receive a lot of freedom as well as room for entrepreneurship.
Instead of just following trends, we examine the content critically. We innovate because we really want to contribute to the world of tomorrow.
Unique projects
Work hard, play hard
At Iv we work on projects that challenge us to push the boundaries of what is technically possible.
We like to have fun at Iv, which is why, for example, it has become a tradition to attend the UEFA European Championship and FIFA World Cup.
Diversity From infrastructure to submarines: we are the most diverse engineering company in the Netherlands.
