The Stadtwerke Cottbus GmbH (hereinafter “Stadtwerke Cottbus” or “SWC”) is the municipal supplier for electricity, gas, and heat supply in Cottbus. SWC, among other things, is the owner of a combined heat and 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 new combined heat and power unit (CHP) with a pressure heat accumulator erected at the HKW Cottbus site. As part of the decarbonisation of district heating generation, Stadtwerke Cottbus plans to erect a heat pump system operated with seawater from the Cottbusser Ostsee (project “Seewasserwärmepumpe”). Initial preliminary investigations/preliminary planning for the Seewasserwärmepumpe project are available. A plant with a thermal output of approximately 35 MW is to be erected. The Seawater Heat Pump Plant is to be installed on the site of the Heizkraftwerk Cottbus in Werner-von-Siemens-Straße in Cottbus and integrated into the existing plant stock at the site – including connection to the district heating network. The seawater is transported via a two-string (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 Seawasserwärmepumpe is to be developed and validated as part of the planning services subject to this contract. Commissioning of the Seawasserwärmepumpe plant is planned for 2028. According to current considerations, the execution services are to be awarded in lots. The essential planning and specialist planning services for the Seewasserwärmepumpe 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 plant and all other technical equipment of the project, excluding the electrical and control technology and 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 technology and the necessary conveying systems) Lot 3 – Structural engineering services for buildings and open spaces (including (1.) access road and traffic areas, in each case including road/ path construction and other ancillary facilities and (2.) facilities for the treatment/ infiltration of rainwater without building character on the open spaces) Lot 4 – Structural engineering services Further necessary services such as fire protection services according to AHO and environmental consulting services environmental impact assessment including sampling, species protection report, building acoustics (sound protection), geotechnics, emission and immission reports and ecological construction supervision are to be awarded separately. Framework agreements are to be concluded with the contractors of Lots 1 to 4 and the further services.
