PIO_202511 RFI Buisvijzel

Flanders protects itself against flooding with more than 200 pumping stations, mostly outdated. About a quarter of them use jacks, valued for their reliability, efficiency and fish-friendliness – a growing priority within policy and regulation. The tube auger scores even better on paper in terms of energy consumption and fish safety, but is hardly applied in Flanders due to practical challenges. However, fragmented management and insufficient validation in the market have so far hampered the roll-out of the tube jack in those renovations. In order to stimulate this and to acquire more knowledge about the tube jacks, the Department of Mobility and Public Works, together with the Province of West Flanders and Westkustpolder, wants to have a tube jack modelled and tested on a scale model. They then want to install the tube auger and test it effectively in an existing auger pumping station. Manufacturers optimize the design with CFD modelling and scale models, supported by NeXperta (Concrete and Steel Expertise Department and the Hydraulic Laboratory). The test results refine the empirical formulas and determine whether tube jacks are a suitable alternative to replacing existing jacks. The project is supported by the Innovative Public Procurement Programme. In preparation for the preparation of a specification for the guidance of this process, the Flemish government wants to question the interest of the market parties. More information can be found in the document attached to this RFI. There you will also find contact details and a questionnaire for a 1-on-1 interview.
