The Verbandsgemeinde Zweibrücken-Land intends to increase, expand, modernize and partially rebuild its existing administrative building in 66482 Zweibrücken, Landauer Straße 18 - 20. The existing administration building was built in 1952. It is a building in solid construction. In 2022/23, a feasibility study on architecture was commissioned to clarify the basic feasibility. Findings from this feasibility study on architecture are made the basis of the project goals. As such have been identified (here short version, long version see file “Task description”): 1. Reinforcement of the building to accommodate additional rooms for administration. 2. The extension of the existing administration building primarily refers to the creation of a second structural rescue route. 3. Reconstruction measures on the existing building are required in particular in connection with spatial optimization by laying uses. 4. Modernizations primarily concern the energetic upgrading of the entire building envelope and other components by means of thermal insulation measures as well as the improvement of the energy balance, supported by technical measures. 5. Deficiencies in preventive fire protection must be corrected. 6. Establishing accessibility. 7. Sound immission protection at least of the roadside premises. 8. Improvement of the room acoustics of individual rooms. 9. Energy efficiency and sustainability, implementation of a sustainable energy concept.-- 10. Compliance with profitability and costs, construction cost ceiling of EUR 4,037,000 gross for KG 200 to 500 in accordance with DIN 276 December 2018. According to the current standardized calculation, the pro rata cost groups (KGs) are: KG 400 (Bauwerk Technische Anlagen) approx. 843,000 EUR gross. Groups 4, 5, 6, 7 and 8 account for a total of around EUR 460,000 gross. The allocation of costs to the individual plant groups can currently only be carried out in a rough or standardised manner on the basis of characteristic values. Shifts and adjustments within the cost groups are to be expected at the time of the cost estimate. No preliminary investigations have been carried out with regard to the invitation to tender for these plant groups. On the subject of the contract, the contracting authority's current findings are summarised as follows: AG-4 Plant Group 4 Power Plants: For the existing building, an inventory of the existing technical system must first be drawn up as part of the service advertised here. The existing plant must be renewed (depending on the inventory, if necessary only in parts) and extended. An extension of the low-voltage systems is to be replanned in the increase and connected to the existing systems. In addition, a self-generating plant in the form of a photovoltaic system must be set up in conjunction with the top-up. In addition, an emergency power supply for the administration building is to be built. In connection with an operating cost calculation, it will be necessary to check which building heating system in connection with the energetic upgrading of the building envelope and with the arrangement of a photovoltaic system makes economic sense to meet the legal requirements, cf. project objectives 4 and 9. >>> AG-5 Plant Group 5 Telecommunications and Information Technology Plants: For the existing building, an inventory of the existing technical system must first be drawn up as part of the service advertised here. So far, the need for the refurbishment of a fire alarm system for the entire building has been identified. It is also necessary to set up a server room in a suitable location, in conjunction with the necessary installation connections.>>> AG-6 Group 6 Conveyor systems: Accessibility according to ‘DIN 18040 Part 1: Buildings accessible to the public’ requires the installation of a lift system.>>> AG-7 Group 7 Manually operated fire extinguishing systems and 2 tea kitchens (meeting room, staff room) are identified as usage-specific systems.>> AG-8 Plant Group 8 Building Automation: The customer currently assumes that the automatic control, control, monitoring and optimization of the technical systems heating, if necessary. Ventilation, lighting, shading of the entire building is useful and necessary.>>> For further details, please refer to the tender documents.
