The current Juliana Lock, built between 1932 and 1936, is unable to meet the demand for more and larger scale transport over water, as the maximum width is too limited for modern inland shipping vessels. The new lock means that pleasure crafts and professional vessels can be separated, to benefit safety and flow. The new lock will be 14 m wide, so the Van Lent shipyard, situated behind the lock, can build larger super yachts. The lock will be built right next to the present lock. Building started in October 2012 and the commissioning will be in 2014.
The Province of South Holland contracted Van Hattum & Blankevoort to build the new lock, in cooperation with Vialis, de Bondt van Hulten and Hollandia.
Volker Staal en Funderingen executed a large part of the foundations scope for the construction of the lock for Van Hattum & Blankevoort. The scope of work includes the foundations of the lock heads, the vibration-free installation of a combi wall for the new draw bridges, the anchoring of the permanent and temporary sheet piling and combi walls, the removal of old fendering and guiding constructions and the design, manufacture and placing of new fendering and moorings for the vessel waiting for entering the locks.
