Last Thursday a group of students of Mollier went to Schiedam towards the new land tunnel of the A4. This excursion was organized by Heijmans. The day started with a general presentation about Heijmans provided by HR manager Floris van Koningsbruggen. He was followed by John Voeten, manager of Heijmans Installation, who presented the design of the tunnel and the bottlenecks they were facing. The excursion ended with a tour around the construction site with a retired employee of the ministry of infrastructure and environment.
