The Gaasperdammertunnel near Amsterdam will be the longest land tunnel in The Netherlands. The length is 3 kilometers. As planned traffic will drive through the tunnel in 2020 and in 2021 the park at tunnel roof will be ready. The project is part of the programme Schiphol-Amsterdam-Almere of Rijkswaterstaat. It is tendered as DBFM contract. This means that the winning contractor combination (Ballast Nedam, Heijmans, Fluor, 3i Infrastructure) is responsible for design, build, finance and maintain the A9 highway, the tunnel and all of its (tunnel) technical installations for 20 years.


The consortium needed to win the bid in order to design, build and maintain the tunnel. They need to proof the asset owner, Rijkswaterstaat, that they meet requirements and perform in accordance with the contract (and prevent penalties due to unavailability). For investment decision making throughout the life cycle of the contract and system the clients needs reliable maintenance and replacement cost. On time delivery of design of (sub)systems of tunnel technical installations and choosing design strategy for tunnel and civil work is a challenging process.
