Planning services for increasing the flow rate of thermal water from the Unterschleißheim geothermal plant
About This Opportunity
TranslatedThis tender seeks comprehensive engineering services for the planning and execution of measures to significantly increase the thermal water pumping rate at the Geothermal Plant in Unterschleißheim. The scope of work encompasses engineering services for technical equipment as defined by §§ 53 ff HOAI and Annex 15 HOAI 2021, specifically covering plant groups 7.2, 4, and 8. The services are required for basic performance phases 1 through 9, within fee zones III or II, and include special services as detailed in the technical description and engineering contract. The primary objective is to enhance the thermal water extraction rate to a minimum of 120 liters per second, with a potential target of 130 liters per second. This will necessitate modifications, new construction, or adaptations to existing components across all relevant operational sites within the geothermal circuit. Key considerations include managing increased flow velocities and pressure losses associated with the higher pumping rates. The project aims to optimize the plant's capacity and efficiency through detailed planning, design, and oversight of the required infrastructure upgrades and modifications.
This is a consulting contract in the energy and power, architecture and engineering and construction and civil works sectors. Located in Germany, Europe, this opportunity is open to firms and consortiums, with an estimated budget of EUR 650,000.
