New sea lock IJmuiden


OpenIJ (BAM-PGGM, VolkerWessels and DIF), commissioned by Rijkswaterstaat.

Project duration:

OpenIJ has been working on the sea lock since 2015. Aelbers has been working on the project since 2017.

Aelbers’ commitment:

204 employees

In brief:

The scale of the lock is 70 meters wide, 500 meters long and 18 meters deep.

The project

The Noordersluis in IJmuiden is due for replacement after almost 100 years of service. That’s why a new lock is now being built. This new sea lock will be longer, wider and deeper than its predecessor from 1929. When completed, it will be the biggest sea lock in the world.  

Our solution

We are supplying carpenters with the required training and are compiling teams for working in shifts.

Our strength

We are devoting extra attention to working safely both along and above the water: our construction site coordinator proactively ensures everything is being done with the utmost safety in mind. We are also taking responsibility for the complex planning of shifts in all different parts of the project.
