Rokin Station will be located where once the car park stood, between Dam Square and the Spui. There will be one entrance facing Dam Square and another one facing the Spui. This station will be 21.5 metres below Normal Amsterdam Water Level (NAP). Each day, some 57,500 passengers will be using this station. This will make it the second busiest station of the Noord/Zuidlijn, after Central Station.
Underground parking facilities for cars and bicycles
Since the site needs to be excavated to build the station anyway, it will be relatively simple to build an underground car park as well. There are also plans for an underground parking facility for bicycles.
A square without cars
When the station is finished, the space above it at street level will function as an elongated public square.
Roof of the west side of the station is finished
Different methods are being used to build the roof of the station. The largest and most central part of the roof was made in 2006. This section is approximately 15 to 20 metres wide, 2 metres thick and has a length of 115 metres.
First, steel girders or struts are positioned between the walls to keep them in place while the top few metres of soil are dug away. Twenty-two gigantic prefab concrete joists are then laid out on the construction site, in between the walls. Sheets of metal are laid down between the joists, onto which concrete is poured on the spot. In this way, all parts of the roof will be connected with each other, which will help to make the whole roof sturdy.
Other building activities around Rokin Station
The two entrance halls on the north and south sides of the station are finished. The contractor is currently working on the so-called escalation points, where moving staircases will eventually be installed to carry travellers down to the platform from the entrance halls above.
In the first quarter of 2007, the contractor moved the construction site back over to the west side of the Rokin in order to resume the building activities there. The tram now rides on the new track along the west side of the Rokin. The new tram stops are located adjacent 118-132 Rokin (for trams going towards the Dam) and 92-102 Rokin (for trams going towards Muntplein). There is no longer a tram stop across from the V&D department store (for trams going towards the Dam). For the stretch on Rokin between numbers 22 and 102, cars now drive over the tram tracks. Cyclists heading towards Dam Square ride in a bicycle lane beside the tram tracks.
Workers on the construction site adjacent 55-109 Rokin are using two machines to search for possible obstacles in the ground. Any obstacles they find will be removed using a special kind of derrick. They have also begun installing a grout brace deep in the ground. The noise from these building activities may be disruptive for those in the vicinity. Adjacent 17-55 Rokin, the construction site is being set up for injecting a watertight layer of soft gel very deep in the ground. This activity will last for about nine weeks, and people living and working nearby may find the noise disruptive.
Rebuilding the bridge over the Damrak (Bridge no. 303)
Bridge no. 303, which was dismantled in connection with the construction of the Noord/Zuidlijn, will now be rebuilt. From early February until the end of April, the circular cofferdams will be made in which the contractor will be building the abutment and the piers of the bridge (starting in May). To this end, steel sheet piling is being vibro-driven into the ground. People living and working nearby may find the noise from these building activities disruptive.
Building activities on the north end of Rokin Work in preparation for the boring of the tunnels of the Noord/Zuidlijn commenced on the north end of Rokin, behind the ‘Industria’ building, on Monday, 18 September 2006.
The current building activities will make it possible to minimise the movements in the ground at a later stage, when the tunnel-boring machines pass by. In effect, this concerns a precautionary measure. To make this preventive measure possible, a deep vertical shaft is being built on the construction site. By means of this shaft, it will be possible to support the foundations of buildings in the vicinity wherever necessary.
The construction of the shaft has already reached an advanced stage. Lorries are now delivering the ring-shaped concrete elements that make up the shaft, and soil is being carried off. Over the course of a single day in the week of 16 April, the floor of the shaft will be poured using underwater concrete that will be carried to the site by concrete-mixer lorries. The water will then be pumped from the shaft, after which the work on the shaft will be completed.
