Awards of this contracting authority

Justification

Der Grundauftrag basiert auf einem offenen Submissionsverfahren. Die Prüfingenieurleistungen im Gewässerraumprojekt Kanton Zürich wurden im Frühling 2020 öffentlich ausgeschrieben und das Mandat «Prüfingenieur B» an die Hunziker, Zarn & Partner AG, Aarau, vergeben (BD-Vfg. Nr. 0299/ 2020). Die Zusatzleistungen der Vergabeerhöhung stehen in unmittelbarem Zusammenhang mit der Vergabe der Hauptleistungen und ein Wechsel der Anbieterin für die besagten notwendigen methodischen Präzisierungen würde substanzielle Mehrkosten mit sich bringen. Die Vergabeerhöhung erfolgt somit gestützt auf Art. 21 Abs. 2 lit. e IVöB (2019) frei-händig.
