OpenIJ is going to enlarge its work area in three locations this month. It will continue its activities near the inner lock head (1) of the North Lock and this means that the work area is slowly ‘spreading’ eastward. Some additional pile driving will be necessary and this may result in noise nuisance - also for ships passing the area.
At the same time, works are starting on the construction of a temporary flood defence at the southwest side (2) of the North Lock. This means there will be activities and equipment on the water in this location as well. Although the activities will be clearly visible, the equipment used will stay behind the existing fendering system.
Also this April, a start will be made with the installation of pipe piles for the fendering system between the cofferdam of the outer lock head and the Middle Lock (3). OpenIJ - the building contractor - will first install the pipe piles and then place the fendering system. The permanent construction also includes the installation of additional pipe piles behind the fendering system at a later stage.
Works on the lock chamber walls and in the cofferdams (lock gate chambers/recesses) will also continue this month.
