Germany – Sewage, refuse, cleaning and environmental services – Entsorgungs- und Laborleistungen aus dem Projekt GEN2.0 - PS-Rathenau

Hamburg Energiewerke GmbH (HEnW) aims to establish an environmentally friendly and efficient heat supply in the areas around Hamburg Airport. Part of the project is the construction of an underground district heating booster station in the area of the Alster crossing, which will function as a pressure boosting station. The present tender includes only the disposal services within this construction measure. The construction site is located within a roadside area of Traute-Lafrenz-Straße at house number 116, 22297 Hamburg. For the creation of the excavation pit, a approximately 33 m deep and 1.00 m wide slurry wall is planned. This results in a calculated slurry wall material of approximately 3,000 m³, or approximately 7,000 tonnes. The total volume of soil to be excavated for the creation of the excavation pit is approximately 7,000 m³, or approximately 12,800 tonnes.
