Renovation Heinenoord tunnel: tasks construction companies | Rijkswaterstaat

Armand Ellsworth (Dura Vermeer), Peter Paasse (SPIE) and Hans Kottenhagen (SWARCO) explain what part of the work they are responsible for.

The Heinenoord tunnel has a decisive role as a connection between South Holland, West Brabant and Zeeland. By renovating and repairing the tunnel technical installations and replacing the operating, control and monitoring system, the tunnel will once again meet the latest requirements for tunnel safety.

Savera III (Partnership for Replacement and Renovation Approach), consisting of Dura Vermeer, SPIE and SWARCO, is carrying out the renovation.

Dura Vermeer

Armand Ellsworth, director of projects at Dura Vermeer, starts. ‘Mapthrough the swing, we as a construction consortium are responsible for everything related to the infrastructure and the architectural part. With the construction of the central tunnel channel as a focal point.’

Ellsworth continues: ‘Of course we have been preparing for a long time, we are also like 1eactually got to work in the tunnel. With demolition work, sewerage etc. We call that demobilization and mobilization, or tearing down and cleaning up and then building new things. But also outside the tunnel with the diversions for when the tunnel is closed.’ He indicates that they will then also be involved in testing and opening up, but that their role will be somewhat smaller, and it will primarily be up to the other combinators.’

‘Personally, I still think it’s special that I was also in 1e renovation of this tunnel in 1994. Techniques have of course developed further, but the most striking thing is that Rijkswaterstaat then did more itself. Now they entrust a larger part to our construction consortium. It makes our work more complex, but certainly also more fun and challenging.’emphasizes Ellsworth.

SPIE’s responsibility

In short, Combinant SPIE together with SWARCO is responsible for the technical tunnel installations. To get a better picture of this, Peter Paasse, director of Smart Cities & Energy, mentions what it all boils down to: ‘Think, for example, of the extinguishing facilities, the escape doors, the ventilation and the air conditioning in the tunnel.’

“Incidentally, what we have already done is the installation of a new energy supply in October last year. With 2 instead of 4 power supplies, and without emergency generators running on diesel.’ SPIE has already received quite a few compliments for this.

‘Rijkswaterstaat even made a video of it’says Paasse. ‘The fact that it turned out so well is ultimately due to good preparatory work, in addition to craftsmanship.’

An important point of attention throughout the renovation is the purchase of materials necessary for all installations. Easter: “We are very aware of that, because there is a shortage right now. It is now a big challenge, both in terms of delivery time and price. For example, for the summer closures in 2023 and 2024, we really need things. Then you sometimes have to choose shorter delivery times and a higher price. Otherwise you’ll run into problems with the planning, and that’s the last thing you want.’

SWARCO activities

‘In terms of activity, the realization of a standard system for operating, managing and monitoring the tunnel stands out for us, we call it 3BT’says Hans Kottenhagen, Manager Engineering and Development at SWARCO.

“We are also involved in the installations together with SPIE. Construction of the standard 3BT was a separate part of this tender. The idea was to create a standard that can also serve as a design for the tunnels that will subsequently be renovated.’ This means that SWARCO must ensure that all the other tunnels’ functionalities are also included in this model.

Kottenhagen: “For example, one tunnel has a different type of escape route than the other. By already taking this into account, there is a standard for Rijkswaterstaat and you save on making a design again and again. For other renovations, a contractor must only implement this model.’

The model and software are in the final stages. This is followed by a test period. ‘In the Heinenoord tunnel, in 2023 we will work on the realization of installations in the central tunnel channel. This will still be managed via the existing system. We will implement the standard 3BT system during the renovation of the rest of the tunnel installations in 2024.’
