About this tender
The buyer, Dessauer Versorgungs- und Verkehrsgesellschaft GmbH (DVV, Stadtwerke), is procuring engineering planning services for the district heating network (FW-Netz) in Dessau, Germany. The services cover HOAI-style service phases (Leistungsphasen, LPH) 2 to 4, from preliminary design through to approval documentation. The notice is described as Modul 1 of the programme. Maßnahmenpaket 1 (Netzausbau und Netzverdichtung) covers the investigation and planning of expanding and densifying the district heating network in the Stadt-Nord area, based on an assumed 440 additional house connections. LPH 2 covers route variant studies, hydraulic pre-sizing, grid integration, feasibility and cost estimation, and a recommended preferred variant. LPH 3 covers detailed hydraulic calculation, pipe sizing, house connection planning, pipe statics, compensation planning, route planning, interface planning and cost calculation. LPH 4 covers the technical approval and consent documents. Maßnahmenpaket 2 (Leitungsoptimierung, Temperaturabsenkung und Dezentralisierung) aims to technically and economically optimise the existing network. LPH 2 covers a digital network model, dynamic-thermal simulation, supply security verification, temperature reduction studies and decentralisation options. LPH 3 covers target network structure, detailed hydraulic planning, temperature curves, network conversions, control stations, bypass solutions and economic evaluation. LPH 4 covers the approval documents for the measures confirmed in LPH 3. Maßnahmenpaket 3 (Intelligente Hausanschlussstationen) covers planning the replacement of up to about 250 conventional house connection stations with intelligent stations suited to lower network temperatures. LPH 2 covers stock analysis, station typing, metering, control and communication concepts, SCADA connection and return-temperature analysis. LPH 3 covers sizing, heat exchangers, control, sensors, data points, communication, SCADA integration and load management. LPH 4 covers connection, modification and approval documents. The awarding authority decides after each LPH 2 or LPH 3 whether and to what reduced extent planning continues. Section 3.2 of the tender documents sets out staged call-off rules. Total duration is not stated in the notice text.
