As a result, the additional costs of this dbfm project amount to 200 million euros. A huge amount that builders have to spit out compared to the contract sum of over 500 million net contact.
The expedition will not suffer from delay, because until the completion of the new lock the Noordersluis now works longer. It is expected that the first ships will be able to use the new lock at IJmuiden at the end of January 2022.
The Caisson method takes longer
The OpenIJ contractor consortium (BAM and VolkerWessels) has announced in December 2017 that these changes were necessary. The price was surprisingly low, but there seemed to be a huge miscalculation. The miss costs 138 million euros and is entirely at the expense and risk of the builders, then announced. BAM chef Rob van Wingerden and VolkerWessels Jan de Ruiter are both bullets.
The consequences of problems with door-outs were mapped during the last period. External experts evaluated their planning and technical construction. The result is that the door frames can be built with adjustments according to the box method, but more time is needed.

The scale on which the caisson method will be used at IJmuiden is unique in the world. Centimeters before centimeter, the doors with a large building size will soon sink to a depth of 23 M. The preparation for sinking will take longer. Auxiliary constructions are now built to keep the caisson stable during the sinking. These are again broken down after the pouring process. The walls of the sea side caisson are currently almost up. The sinking of this caisson will begin in the summer of 2018.
Lock gates in Korea
During the last period, in addition to the necessary adjustments in the door hinges, the other parts of the lock have been worked. For example, the construction of the column walls is progressing and finishing is underway in South Korea for the manufacture of the locks. Doors are expected to arrive in the Netherlands by the end of this year. In addition, work is being done on the Sluis Operation Center and the new pipeline between the Middensluis and the new Sealock was recently installed
Noordersluis more open
Rijkswaterstaat is currently identifying the measures needed to keep the Noordersluis operational. Towards the future of Noordersluis in the longer term, research is in progress since the beginning of the year 2017. The first results of this research should be known by the middle of the year 2019. [19659002] In order to provide space for ocean-going vessels, the construction of the largest lock in the world has been in progress since 2016. The maritime lock provides independent access to the tides at an easy accessibility and safe ports and businesses along the North Sea Canal. The new lock will be 500m long, 70m wide and 18m deep
