August Update for IJmuiden Sea Lock Project

During this month, OpenIJ will – under the New IJmuiden Sea Lock project – continue working on the walls of the inner lock head and on the flood defenses.

Near the outer lock head, OpenIJ is carrying out excavation work for the lock sill cofferdam, reported the Port of Amsterdam.

At the inner lock head, OpenIJ is still working hard on the installation of reinforcement steel for the walls. The builders are currently busy with concreting stages 3 and 4 for the walls at a height of 13 meters above NAP (Normal Amsterdam Level), the Port said.

The officials also added that the walls of the inner lock head will be constructed in seven stages in total. The reinforcement steel for the walls of the inner lock head has already been installed up to a height of 18 meters above NAP.

Two lock gates will be installed into the inner lock head, namely the gate on the North Sea Canal side (the inner gate) and the spare lock gate.

Also in August, work will continue on the future flood defenses. The height of the flood defense will be 8.85 meters above NAP. Contracting consortium OpenIJ is currently working on the walls of the flood defense. The future public road will be built on top of the flood defense.

At the moment, OpenIJ is carrying out excavation work for the lock sill cofferdam next to the outer lock head. In this cofferdam, the lock sill is being built on which the future outer gate will run for closing and opening the lock, concluded the Port of Amsterdam.
