Implementation is taking place under complex conditions: in an urban environment, along heavily used pedestrian and cycling paths, and with due regard for heritage protection—especially at the Heilig-Kreuz Bridge. In addition, the work on and in the Ill’s riverbed places high demands on logistics and construction processes, for example through temporary construction roads in the water or the need to respond flexibly to flood periods.

It is a major technical undertaking and at the same time an example of proactive flood protection that safeguards habitats and the population’s safety in the long term. The work is being carried out in close coordination with the City of Feldkirch and with consideration for the concerns of local residents—an effective combination of engineering expertise, consideration, and responsibility.
