VolkerWessels Telecom takes care of the entire process surrounding the construction of high-quality digital infrastructure. From analysis and design to construction, installation, maintenance and management. The ultimate goal? Optimal connectivity down to the last square inch. This is how they make living and working as comfortable as possible.



VolkerWessels Telecom’s (legacy) application landscape (VWT) has evolved over the years. Knowledge about this is mostly “in people’s heads,” and applications no longer always match the changing demands of the business. Within VWT, another team was working on new technology and innovation.

Leon van der Heijden, director of digitalization & ICT at VolkerWessels Telecom, took on the challenge of bringing these two worlds together. “Standardize to make flexible” is his statement in this regard.

First, a blueprint of the desired future architecture is needed in order to then (re)build future-proof applications, in the cloud.



Leon enlisted IT Rockstar Hans Hart to take apart and rearrange “the spaghetti. The goal of the new architecture blueprint is to eventually move into a full SaaS environment. With the blueprint, VWT can start taking the necessary steps to become truly data-driven.

Leon: “Capturing data to unlock is important to leave the knowledge behind for the new generation. Data gives us more insight into the operation, bottlenecks and also what is going just right.” This ensures that problems are solved faster and helps it serve customers better.

Team Rockstars IT has laid a good foundation for the future of VolkerWessels Telecom. 100 applications have now been reduced to 7 basic applications. “Hans knows how to make a good choice between the possible solutions and stands behind them 100%.”


Collaboration with Team Rockstars IT

Leon: “Team Rockstars IT switches quickly and really listens to our needs. They see how they can suggest the best suited candidate to this. You guys exude a certain professionalism and expertise. There is no other vendor that invests as much in our customer relationship.”

”You exude a certain professionalism and expertise.”
