After the cessation of hard coal mining on the Ruhr at the end of 2018, some tailings piles had to be designed according to the specifications of the approved landscape plans.

The final design of the tailings pile Lohberg Nord extension is to be implemented in accordance with the specifications of the mining operation plan. In total, the tailings pile is to be finished with approx. 3.5 million m³ or 7 million tonnes of profiling and recultivation material. As of 31.12.2022, approx. 50% of the masses had been installed.

External masses are required for the profiling of the surfaces, which are made available via RAG. RAG commissions the Contractor to inspect and release the soil masses by a recognised expert (soil assessment), to check delivered soil masses with regard to their compliance with the declaration analysis (material suitability monitoring) and to accept, weigh and record incoming trucks.

For the profiling of the area, foreign masses are required to a large extent. These are procured by the land management of RAG Montan-Immobilien GmbH and its contractual partners.

This award procedure concerns engineering services and expert services. Specifically, this involves the expert installation supervision in the installation areas K1 and K2, the monitoring of the requirements from the water law permit in the context of soil installation as well as the acceptance, weighing and recording of the arriving trucks by qualified weighers to be provided by the contractor.
