What is being procured?

Scope of work

Die Dienstleistungen wurde im März 2025 ordentlich im offenen Verfahren Binnenmarkt ausgeschrieben (SIMAP ID 10548). Aufgrund von unvorhersehbaren Mehrleistungen, insbesondere Wassersaugarbeiten infolge von Wassereintritt in das Gebäude sowie der Entfernung von Fremdkörpern im Hinblick auf den Bodenaufbau reicht der prognostizierte Vergabewert für die vorgesehene Projektdauer nicht aus. Deshalb benötigt die BVB bis zum Ende des Projektes einen Zusatzauftrag bei derselben Dienstleisterin.
