Cottbus Stadtwerke GmbH (hereinafter „Cottbus Stadtwerke“ or „SWC“) is the municipal supplier for electricity, gas and heat supply in Cottbus. SWC is, among other things, the owner of a power plant at Werner-von-Siemens-Straße 16 in Cottbus („HKW Cottbus“) for the generation of electricity and heat for the district heating network. The HKW Cottbus is operated by a subsidiary, HKW Heizkraftwerksgesellschaft Cottbus mbH (hereinafter „HKWG“). The heat supply is currently covered to approximately 50% by a combined heat and power plant (CHP) newly built at the HKW Cottbus site, including a pressure heat accumulator. As part of the decarbonisation of district heating generation, Cottbus Stadtwerke plans to build a heat pump system operated with seawater from the Cottbusser Ostsee (Project „Seawater Heat Pump“). Initial preliminary investigations/preliminary planning for the Seawater Heat Pump project are available. A plant with a thermal output of approximately 35 MW is to be built. The seawater heat pump system is to be installed on the site of the Cottbus Power Plant at Werner-von-Siemens-Straße in Cottbus and integrated into the existing plant at the site – including connection to the district heating network. The seawater is transported via a two-strand (2x DN 1,000) ring line („Loop“) from the Ostsee through the city of Cottbus (also directly past the HKW Cottbus) and back into the Ostsee; the Loop is a separate project. The exact plant concept of the seawater heat pump is to be developed and validated as part of the planning services subject to this tender. The commissioning of the seawater heat pump system is planned for 2028. The award of the construction services is currently planned to be made in lots. The essential planning and specialist planning services for the Seawater Heat Pump project are to be awarded to suitable contractors in four lots: Lot 1 – Specialist planning of the technical equipment of plant groups 1 to 3 and 7 and 8 according to HOAI, in particular the heat pump system and all other technical equipment of the project, excluding electrical and control engineering as well as conveying systems (plant groups 4 to 6 according to HOAI) and structural engineering services for civil engineering works Lot 2 – Specialist planning of the technical equipment of plant groups 4 to 6 according to HOAI (electrical and control engineering as well as the necessary conveying systems) Lot 3 – Structural engineering services for buildings and outdoor facilities (including (1.) access and traffic areas, in each case with road/ path construction facilities and other accessories as well as (2.) facilities for the treatment/ infiltration of rainwater without building character on the outdoor facilities) Lot 4 – Structural engineering services Further necessary services such as fire protection services according to AHO and consulting services for environmental impact assessment including sampling, species protection assessment, building acoustics (sound insulation), geotechnics, emission and immission assessments and ecological construction supervision are to be awarded separately. Framework agreements are to be concluded with the contractors for Lots 1 to 4 and the further services.
