in combination with other forms or materials. Waterworks Since 2001 Kuijer has been working on a group of seven large-scale sculptures on the strip between Isotopenweg and the Amsterdam-Rhine Canal, at Lage Weide industrial estate in Utrecht. These monumental, concrete sculptures are 12 metres high and up to 14 metres long. They are made from a single piece and a single material. In other words, they are monolithic sculptures. They basically consist of two materials: concrete and reinforcing rods. The sculptures project has been specially made for the location. The group establishes relationships at a number of different levels with water and transport, and with the industrial surroundings of Lage Weide industrial estate. The sculptures contrast with the purely functional surroundings and add a human dimension to the immense and expansive area. Kuijer used forms based on the scale of our own body as a mould. The sculptures contain references to water, for example, a moulded rowing boat, surfboard and a garden pond. One specific possibility offered by concrete is making imprints. Water Work IV Overstag (Go About) uses, more so than in the other sculptures, the richly contrasting and expressive possibilities of the sculptor's skin. Between 2010 and 2013 a sloping embankment was created between the sculptures. This tailoring of the landscape links the sculptures together to form a tight-knit unit. From the point of view of urban planning this anchors the project firmly in the surroundings. Nowadays the sculptures are also illuminated at night. Water Work VII Cohesie (Cohesion) is the final element in the series and is also the tallest, at 12.70 metres high. This sculpture is located next to the Werkspoorbrug along the banks of the Amsterdam-Rhine Canal, at the crossing of the international rail and water links between our country and the rest of Europe. Two shapes in the sculpture contain a repeating motif of the coats of arms of the cities of Amsterdam, Utrecht and Basel. One shape is visible for passing ships and the other stands at eye level for passing train passengers. The whole project was unveiled in March 2013 as part of the celebrations to mark the 300th anniversary of the Treaty of Utrecht (1713-2013). Besides being an artist, Ruud Kuijer is also a cultural entrepreneur in heart and soul. There are very few independently initiated sculpture projects of this scale in public spaces.
