Construction consortium ZuidPlus, currently working on the roof for the second passenger tunnel at Amsterdam Zuid station, needed a long Easter weekend to do the work. They started at 20.00 on the evening of Thursday, 1 April. They had two jobs to do: putting foundations in place for two sections of the roof and moving railway track 4 to enable the platform to be widened.
Thursday evening: we remove the platform between tracks 3 and 4.
By lifting away the track, we make room for the excavators.
Friday: we dig out 1,000 cubic metres of sand, revealing the foundation piles previously put in place.
We then hoist the reinforcement cages already there into their final position…
…right across the foundation piles that have been dug open.
The concrete truck is standing by to pour concrete into the cages.
In the meantime, we widen platform 3-4.
Werk nog in volle gang
With the reinforcement cages in position, the concrete can now harden. This process will continue over the coming months, ensuring that, by August, the structure will be strong enough to support the roof of the new station passageway. The work to widen the platform is still in progress, as is the moving of track 4. On 05.00 on Tuesday, 6 April, the trains and metros will resume normal service.
