What is being procured?

Scope of work

Die Naturgefahrenkarte des Kanton Basel-Stadt zeigt, dass der Bettinger- und Immenbach bei sehr starken Hochwasserereignissen grossen finanziellen Schaden verursachen kann. Ein weiteres Schadenspotenzial zeigt sich beim Oberflächenwasser, welches u. a. im Gebiet des Roten Grabens auftritt und in das mittlerweile aufgehobene Gerinne des Hungerbachs führt. Als Grundlage liegt das Variantenstudium und das Vorprojekt vor. Die Aufgabe des vorliegenden Mandates ist die Ausarbeitung des Bauprojektes (Phase 32) und das Bewilligungsverfahren (Phase 33) für den Bettinger-, Immen- und Hungerbach.
