… of measures 2 - Line optimisation, temperature reduction and decentralisation - Package of measures 3 - Intelligent home connection stations The order is assigned in stages. Stage 1: Performance phase 2 - Pre-planning stage 2: Performance phase 3 - Design planning stage 3: Service phase 4 - Approval planning The contract is initially awarded only for stage 1 - service phase 2 (preliminary planning), for all three packages of measures. Stage 2 - Performance phase 3 (design planning) of the packages of measures is an option. Stage 3 - Performance phase 4 (permit planning) is an option. · Planning services for Module 1 LPH 2-4 network engineering measures FW-Netz Dessau : - Package of measures 1 - Grid expansion and grid compaction The subject is the investigation and planning of the expansion and compaction of the district heating network in the urban-north area. The starting point is the assumption of about 440 additional house connections. The actual number and scope of expansion must be checked as part of the preliminary and design planning. LPH 2: Particular attention should be paid to: - investigation of suitable path variants, - technical variant evaluation, - hydraulic preliminary design, - determination of essential network parameters, - investigation of integration into the existing network, - identification of significant crossing areas, - examination of technical feasibility, - examination of temporal feasibility, - excessive cost evaluation, - cost estimation, - recommendation of a preferred variant as a decision template for the WG to determine the scope to be further planned. LPH 3: After decision by AG for a certain possibly reduced scope, the following must be processed in particular: - determination of the preferred solution, - detailed hydraulic calculation, - dimensioning of the lines, - planning of the house connections, - pipe statics, - compensation planning, - route planning, - interface planning, - cost calculation, - deadline evaluation, - verification of the actually required expansion scope. LPH 4: The technical approval and approval documents required for the planned measures must be provided. - Package of measures 2 - Line optimisation, temperature reduction and decentralisation The aim is the technical and economic optimisation of the existing district heating network. The focus is on: - temperature reduction, - hydraulic optimization, - nominal width optimization, - reduction of network losses, - identification of hydraulic weak points, - decentralization of uneconomic areas, - optimization of the network structure. LPH 2: In particular: - development or testing of a digital network model, - adoption of existing data, - model validation, - dynamic thermal network simulation, - investigation of relevant load cases, - investigation of temperature reduction, - consideration of additional connections from package 1, - investigation of the effects of package 3, - poor point analysis, - proof of security of supply, - development of network variants, - investigation of decentralization options, - technical and economic
