Improvements to Tunnel safety
The tunnel system underneath Schiphol’s runways is being renovated. Half of the tunnel tubes will be fitted with new concrete walls, and new technology will be installed throughout the system. Renovation work on the walls of Buitenveldert tunnel has already been completed, so now it’s time for a high-tech makeover: new lighting, fans and sprinklers, as well as a new speaker system and a large number of other smart-technology solutions. The key word is safety. Kaagbaan tunnel will be next, with renovation work slated for later this year.
New concrete, new tech
The importance of safety is reflected in the nature of the renovation work on Buitenveldert tunnel and Kaagbaan tunnel. Escape routes and new technology will ensure that motorists and cyclists can get to safety quickly and with ease in case of an incident, and the terminal’s Control Centre will be able to monitor the tunnels 24/7, shortening emergency services’ response times. In addition, Buitenveldert tunnel now has shorter supply roads and smart traffic lights to ensure traffic flow.
These are our plans
Schiphol’s staff and the businesses located on the airport’s premises will be affected the most by the renovation work. Anyone who has recently driven along Loevesteinse Randweg between P40 and Schiphol Plaza will have noticed the work being carried out on Buitenveldert tunnel. Because the tunnel tubes are taken out of order one at a time, the traffic situation changes regularly. The changes are especially noticeable for:
- Users of Buitenveldert tunnel: business partners, motorists and cyclists within Schiphol’s premises, public transport users, and – to a lesser extent – travellers.
- Users of Kaagbaan tunnel: airside business partners, especially those who work on the Sierra platform.
Concrete renovation work on the Buitenvelderttunnel was completed in late 2017. Intersections were also added to the entrance and exit in order to guide one-way traffic flows into the correct lanes. This was an important milestone in this project. The focus has now shifted away from concrete and towards technical installations, because the next job is to install the new tunnel equipment. Tube A is complete and ready for use. Tube C has been taken out of use while new lighting, public address systems, ventilators, sprinkler systems, vehicle detection systems and other smart safety technologies are installed.
Later in the year it will be the Kaagbaantunnel’s turn. This tunnel has only one tube and therefore employs two-way traffic, with a maximum speed of 30 km/hr. Just like the Buitenvelderttunnel this tunnel will be given an escape route, new technical installations, and will be monitored from the Regiecentrum.
Where and when?
Work began on tunnel technical installations in March 2018. Tube A is now complete and ready for use. Tube C was taken out of use in August. Construction work on Tube C will take three to four months, after which work will start on Tube D. Every time work begins on a new tube the traffic situation changes, because traffic has to be routed through the other tubes. We expect the Buitenvelderttunnel to be ready for use in early 2019. We are also busy planning work on the Kaagbaantunnel; we are currently at the design stage, and the works themselves will begin December 2018.
