Summary
Machine-generated summaryThe City of Karlsruhe, represented by its civil engineering office (Tiefbauamt Karlsruhe), is procuring facade works including metal construction and glass facades for a new laboratory and administration building. The building will be erected on the site of the Karlsruhe wastewater treatment plant, combining existing laboratory and operational buildings. The three-storey building measures about 56 by 25 metres, is subject to critical infrastructure security requirements, and will be raised above ground level due to flood risk and high groundwater, without a basement.
