TEC Tunnel Engineering consultants

Project description

As Schiphol continues to grow, so does the need for proper freight handling. Schiphol Group initiated a new area for handling freight operations, and asked TEC to provide a project study and design for a new freight handling area located just south-east of the runway 06-24. To connect the new freight area with the center of Schiphol, a tunnel was built. The tunnel has a width of 13-m and a total length of 850-m, with an enclosed tunnel length of 550-m. The tunnel crosses the runway and two taxi-ways. At the northern entrance of the tunnel, a connection with an existing tunnel, running perpendicular, had to be constructed. The tunnel crosses the runway and two taxi-ways.
