The future BMW Mobility Development Center near the western Czech city of Sokolov will be one of the largest and most modern in Europe. The construction company Colas was in charge of building, securing and equipping a network of roads and different driving environments: highways, multi-lane roads, urban roads, parking lots, tunnels, autonomous driving areas, and dirt roads as well as mountain roads.

HYDROPHIL, as an engineering firm specializing in surface drainage, was contracted to conduct hydraulic value engineering on the drainage system. The drainage network consisted of road-accompanying swales, drainage pipes and rainwater retention basins. The main design criterion was that the outflow of the Mobility Development Center must not exceed the existing natural drainage outflow from the undeveloped area. The difference is retained in rainwater retention basins and only released from the terrain in a throttled form.

The work performed by HYDROPHIL included the development of a hydraulic model with the software MIKE URBAN +.
