No mean feat given the complexity of the two architectural integral viaducts in particular.
Partly because of the good experience of Ploegam (in combination with Dura Vermeer) in phase 1, Schmitz Civieltechnische Werken was approached by Ploegam, but now in combination with Heijmans, for the sizing of phase 2. "In the first phase, our responsibilities included the main dimensions and dimensions outside of bicycle bridge Tegenbosch, including entering the bridge," says Dave Schmitz. "Now in phase 2, our scope is considerably broader because of the five structures and the fact that we are also doing the sizing of the road construction work." His brother Mike adds: "Here we can maximize our knowledge and expertise; we have a lot of experience with such extensive infrastructure projects since 1999." Having been founded by Jan Schmitz nearly 22 years ago, Schmitz Civieltechnische Werken has since grown into a multidisciplinary company.

Combination Heijmans-Ploegam does not make things easy for Schmitz Civil Engineering Works. "The challenge lies mainly in the complexity of the two integral viaducts," says Dave. "They are absolutely two beautiful artworks, but the many angled shapes make it not an everyday job to measure the artworks precisely outside in the field. On the V-pillars of KW03, for example, no straight line can be discovered. Moreover, all the angles run into each other. In order to visualize all this precisely, we made a 3D layout file of the V-pillar which we then read into our equipment for measuring outside. In doing so, we use very specialized equipment." Mike: "We are a small but innovative company with very specialized employees as well as equipment. That makes it easy for us to handle such projects and move quickly."
In addition to large(er) infrastructure projects, Schmitz Civil Engineering Works also deals with smaller (regional) reconstruction projects. "We like to stay small, stand for quality, but are multidisciplinary," Dave concludes. It turns out to be a golden combination.
