Hierzijnwij.nu First track under the Damrak by
To Rokin off Marinus: "We are now about a few weeks working on the construction of the railway. In the west tunnel between Noorderpark to Rokin is already off track. On the bills and the cross-over after, transport sa this tunnel is equipped with rail. "
Where are the bills? Ah, and where are these bills and cross exchange complexes? Marinus, "On the route of Noorderpark to Rokin get 7 points and one cross-over at Central Station. The latter comes in November and mounted mid-January 2015, the other orders transport sa will be delivered in October and mid-December assembled. "
Other tunnel's turn now to the west tube up to and including the Rokin is provided with track, is the eastern tunnel tube (from Noorderpark to Rokin) to the turn. Marinus: "At the end of October, we expect to have provided both tunnel tubes on this stretch of track. The wait is over or at the last part, the cross-over at Central Station. "
Is good air quality Marinus hitherto satisfied transport sa with the progress of the work? "Certainly. We run on schedule and that's fine. However, we are very critical on the air quality in the tunnel. A proper ventilation in the tunnel is required, otherwise the air quality is not appropriate to work. It has now happened a few times that there went out a ventilation which had come my people out of the tunnel until the fans did it again. So we have to be extra sharp. "
If it is true that people have to leave the tunnel by the failure of ventilation, transport sa would that also mean that a subway just can not start from a station and thus the entire metro traffic could fall out? There are no emergency facilities?

@ Peter Talk Of course this comes to air quality transport sa during construction. Welding, grinding, crushing, grinding, drilling, melting, etc. are all things that can produce all kinds of fumes and dust where you are not good to work or sometimes even harmful. Therefore, there are at work so need extra security.
Egbert, Just checked: We are still not doing welding work in the tunnel. From week 46 we start with the butt welding and thermit start later. When we start with this then all welding fumes through transport sa a source extraction may be taken to a special device where the air is filtered before it goes back into the tunnel again. The air quality is by VIA and VolkerRail continuously measured during the implementation transport sa processes on quality. Also paverwerkzaamheden and work on the remaining stations provide building material. When the ventilation system failure, can worsen air quality. It is therefore important that the ventilation system continues transport sa to run continuously good. Greeting, Renske
Wonderful transport sa that the laying of the rails going so well. And very well that when there are disturbances in the temporary building ventilation system, is beaten transport sa alarm immediately and the tunnel must be vacated. That is simply called: Construction Safety. Then a different question. I regularly see a crane on road and rail wheels VolkerRail North riding. Can this crane once get a video camera and so create a fictional, almost real metro ride, which is then put on this site. Then we have a real idea of how it all times. First outside North, the rechthoekigetunnnel to CS and after the round, bored tunnel to Rokin. Sounds like a good promotion for all work to be performed with.

Trolly, The cross exchange complexes are then delivered this month and will be built later in consultation with logistics. Regarding the dimensions there are no barriers to build the cross points. Greeting, Renske
