Rahmenvertrag für Revisionsleistungen Biologiestraßen (Unterhaltung, Reinigung, Verwertung und Entsorgung im Klärwerk Karlsruhe)

TENDER DESCRIPTION

At the Karlsruhe wastewater treatment plant, a revision is carried out annually on one of the five aeration lines of the first biological treatment stage. In doing so, the tanks are freed from deposits and cleaned after the discharge of deposits. In order to take the respective aeration line out of service only for the shortest possible period and to restore maximum cleaning performance as quickly as possible, this complex revision is, as before, supported by an external cleaning company. A framework agreement is to be concluded for the performance of these services. The contract includes unit prices for personnel, vehicles and equipment, as well as for transport and recovery or disposal of residual materials to be taken away. Based on these prices, the services to be performed during the term of the contract are awarded and invoiced, irrespective of the quantity of services and residual materials arising.
