Project Zuiderzeehaven completed
By placing their signature under the dissolution agreement, on February 22nd, the six shareholders of the Zuiderzeehaven closed the project. Fifteen years after the start, they are looking back on a successful project; the business park now employs 400 direct workers.
In addition, the number of cargoes transported over the water has strongly increased.
More than 1,000 ships annually entered the port. The project is also successful from a business perspective. The partners therefore look back on a successful cooperation.
In 2003 the public-private cooperative started between three public and three private parties: the municipalities of Kampen and Zwolle, the province of Overijssel, Dura Vermeer, de Vries & van de Wiel and the Belgian IPEM. The aim was to develop and exploit the Zuiderzeehaven into a modern and sustainable business park, which offers space to companies that want to switch over to water transport. After all, this seems to be more sustainable than road transport.
This goal is more than achieved. Meanwhile, eleven companies have established themselves on the large-scale site. The majority comes from the region, with which the Zuiderzeehaven underlines its function as a regional business park. With Wärtsilä's logistics center, the fuel depot of Salland Olie and the container terminal of IJDT, the Zuiderzeehaven accommodates large-scale logistics companies. Agrobusiness is also well represented with the activities of Graansloot, Van Wijk & Olthuis and Fuite/Liprovit. That the port is an ideal location for recycling is proven by Hoeben Metalen, which has experienced considerable growth since the move to Kampen. The sustainable nature of the business park is shown by wind turbines, which provide a considerable part of the energy requirements of the companies. The Zuiderzeehaven organisation was one of the initiators of this green project.
Approximately 75% of the business park has been sold. The municipality of Kampen will be responsible for the remaining, thirteen hectares. Kampen will take care of the sale of those remaining plots.
Creating 5 islands in the Houthavens in Amsterdam
For future house-building five islands of the Houthavens in Amsterdam with an area of 6 hectares needed to be reclaimed. The first activity was the dredging of the soft silt layer on the existing seabed. Then a scour protection mattress, consisting of geotextile with osier weeps, has been placed on the sea bottom to guarantee a stable foundation for the future house-building. After the bottom protection was placed, the land reclamation for the islands could take place. The filling process was carried out layer by layer with a sprinkling nozzle on a pontoon attached to the trailing suction hopper dredger by a floating pipeline. By using a limited layer thickness of 0.5 metres the settlement occurred in a regular and controlled way. Once the sand level was 0.5 metres above the water level conveyor belt was used to deliver the remainder of the volume for the new land.
A total of 360,000 m3 of sand was used to fill up the islands.
Maintenance of Dutch river system
The project "Maintenance of the Dutch river system in the southwest of the Netherlands" involves a five year program of maintenance of in total 160 km of rivers. Within this project de Vries & van de Wiel, commissioned by Rijkswaterstaat, is responsible for the monitoring and maintenance of the main waterway network and water systems in the southwest of the Netherlands. By getting reliable and useful information, future levels of the bottom of the river can be predicted.
The area includes the following waterways:
- De Boven Merwede
- De Beneden Merwede
- De Nieuwe Merwede
- De Dordtsche Kil
- De Oude Maas
- De Nieuwe Maas
- Oversteek het Hollandsch Diep
- De Lek
- Hollandsche IJssel
- Bergsche Maas
Sediment nourishment on Rhine
De Vries & van de Wiel has executed, on request of the Dutch Ministry of Infrastructure & Environment a trial-project on the Rhine, near Tolkamer close to the German border. The purpose is to prevent further river-bottom erosion by means of nourishment with a sand-gravel mixture. This is required to maintain the long-term navigability of the Dutch river system.
In total there will be 70.000 m3 of sand-gravel nourished. The material is installed in a thin layer of approx. 30 cm over a large surface (2,3 km long & 100 – 150 m wide). By using split barges the material is applied dynamically, avoiding nuisance to the shipping traffic on the river. It is a real challenge to be “in-control” of this process. According to planning the execution is completed by mid-July 2016.

Realization of a new Kooyhaven in Den Helder
The construction joint venture, consisting of de Vries & van de Wiel and Dura Vermeer, started in May 2016 with the realization of a new Kooyhaven business park. The park will provide facilities for businesses to establish themselves on an area of 21 hectare and develop activities that are directly related to the activities within the port of Den Helder. Along the waterfront a quay wall of 660 meters will be constructed. Around the new port a secondary dyke of 1.4 kilometer will be developed.
The followings works are also included:
- Relocating of existing electricity cables
- Separated sewage works and sewer for fire extinguishing with wells
- Remediation of 1 kilometer of berms and service roads
- Connection of the park to the existing infrastructure
Widening the Juliana canal - under construction
De Vries & van de Wiel Kust & Oeverwerken is - commissioned by Rijkswaterstaat Maaswerken - fully occupied with the activities of widening the Julianakanaal. The maintenance dredging on the entire length of the canal has been completed as well as 4.5 kilometers of steel sheet piling. Two sections of the canal are widened including the new watertight canalbed constructed by the Mattedoor. This custom-made pontoon places mattresses filled with a gravel-bentonite mixture and places gravel on top to secure the mattress on the canalbed. In the spring of 2017 a new canalbed is constructed at Obbicht and the dike replacement between the villages of Berg a/d Maas and Obbicht is executed. All works will be completed in the summer of 2018. After finishing the project bigger ships up to 190 meters in length, 11.4 meters wide and a 3.5 meter draught will navigate through this enlarged waterway.
Moving of the Cortenoever-Voorsterklei Embankment
De Vries & van de Wiel carries out, together with contractor F.L. Liebregts, excavating activities in Cortenoever and Voorsterklei. The activities are part of the water safety programme ‘Space for the River’.
The main works consist in the relocation of the embankments land inwards and the lowering of the ground level in Cortenoever (Brummen) and Voorsterklei (Voorst). Parts of the current embankments will be lowered to shoulders. The works also include the building of roads and cycle paths, the cutting of trees and the demolition of houses.
Dike reinforcement Schoonhovenseveer-Langerak
The reinforcement of the dike along the river Lek between Schoonhovenseveer and Langerak (SLA) is the last project of the “room-for-the-river programme” to get the approval of Minister Schultz of Infrastructure and the Environment. The reinforcement measures, with a length of 3.2 kilometres, will be finished in 2015. Along the dike is an urban intensive area. To minimize nuisance for the residents near the dike, vertical relaxation wells will be used as reinforcement measures for the dike: for a first on this scale in The Netherlands.
Company de Vries & van de Wiel, in collaboration with Heijmans and Movares, has proved that vertical relaxation wells are the best solution to improve the macro stability inward of the dike: an innovative solution that tackles the problem at source.
Sand supply for the construction of the N23 Westfrisiaweg
The province of North-Holland has planned in the coming years to improve the safety, the liveability and the flow of the N23 Westfrisiaweg, a road from Heerhugowaard to Enkhuizen. The realisation of this project is in hands of Heijmans.
De Vries & van de Wiel provides herefore the supply of sand. The sand will be coming from own concession areas in the IJsselmeer and transported with own ships to Hoorn and Enkhuizen. There the sand will be brought ashore. It is expected that in a period of approximately one and a half year, 1,400,000 m3 of sand will be transferred and handled up.
