A complex set of smaller concrete pours

The floors, walls and basement decks of Pumping Station De Neust are produced in wet concrete. This creates a complex set of small formwork and dumps. There are also challenges, such as the concrete connection between the large square and the circular pipes.

BetoLinQ Contractors specializes in wet concrete, iron bracing, shuttering and support. All the elements it supplies are engineered, shuttered and produced in-house. "We were involved in the construction of Pumping Station De Neust at an early stage," says Ruud van den Braak, director of BetoLinQ Contractors. "That is pleasant. Then you can prepare things timely and thoroughly. On construction we have our foreman Mari van Lieshout, who arranges everything here perfectly for us. And the cooperation with Pannekoek is also pleasant. It is a party that keeps its agreements." About six men from BetoLinQ are active on the construction site every day.

The formwork was designed in 3D and machined.

The vast majority of the work is relatively simple for BetoLinQ. The designers prepare the rectangular products, after which the molds are built with Doka Framax's reusable fitting plates and the elements are poured. One exception is the connecting piece that is to collect the water from the wetland and feed it through to the pipe network. "This funnel-shaped element required a lot of engineering," says Van den Braak. "The element was completely designed in Revit Dynamo. Then the 3D mold was built and the round sections were milled until they were the right shape."
