client Altenmünster Municipal Administration
Planning of new inner-city roads, including two central squares in the town centre as part of a village renewal project. During the course of adapting the road layout over the Hegnenbach, three culverts have to be redesigned or adapted. The high groundwater levels and peaty subsoil with limited load-bearing capacity and sensitivity to vibration are particularly challenging. The road drainage system is going to be replanned: some rainwater will be channelled into the receiving water body via settling shafts after pre-treatment, and the remainder will seep away through troughs. Two rain retention and seepage basins outside the town collect additional slope water during heavy rain.
