Germany – Engineering services – Neubau 2-gruppige KiTa mit Vereinsräumen IG Waid, Weinheim - Elektroplanung

The City of Weinheim intends to replace the "Kita Waid" daycare centre on the property at Hammerweg 7 in 69469 Weinheim, plot No. 13113. The project involves the construction of a two-group daycare centre including premises for the IG Waid. The reason for the new building plan is the considerable structural defects in the existing building. The approximately 1,750 m² property is located on the eastern edge of an existing residential area. The property currently houses the existing daycare centre in a basement building that was originally built as a school building. The existing open spaces are mainly used as outdoor play areas and are largely green. The property has a slight inclination towards the west. In addition, there is a significant height difference of almost 3 m in the north-western part of the property. The topographical conditions are to be taken into account, particularly in the building arrangement, barrier-free access and site drainage. A special condition of the project is the existing soil conditions. According to the results of the available exploratory soil investigation, the low-bearing, soft to partially fluid silty layers are unsuitable for a conventional shallow foundation. A deep foundation using pile systems is therefore recommended for the planned replacement building. As a technically and economically suitable foundation type, the soil investigation mentions ductile cast-in-place concrete piles with casing. The geotechnical conditions are to be taken into account in the further planning process and coordinated with the structural and drainage design. A space programme coordinated with the parties involved is available for the development of the replacement building. In addition to the functional requirements of a modern two-group daycare centre and the integration of the rooms of the IG Waid, the necessary outdoor play areas as well as the necessary access and parking areas on the site must be taken into account. The existing tree stock is to be evaluated in the further planning process with regard to its conservation value and any necessary protective measures. In the course of a feasibility study, four planning variants were developed and examined and compared with each other in terms of their urban planning, functional, economic and technical feasibility. A single-storey replacement building with the retention of the characteristic tree stock was selected as the basis for further planning. The preferred variant provides for a single-storey replacement building in the eastern part of the property with a gross floor area of almost 1,000 m². A rectangular building structure with targeted building incisions and a thus loosened, pavilion-like building structure is planned. An essential design goal is the extensive retention and integration of the existing characteristic tree stock. The access to the property and the arrangement of the required parking spaces will be via Hammerweg. Due to the single-storey design, the building can be organised completely barrier-free. During the construction period, an interim solution for the daycare centre is currently required, which is not part of the tender. The variant developed and preferred in the course of the feasibility study forms the basis for further planning. Further planning objectives are listed below: Investigation of conventional and modular construction methods, Passive House orientation and prospective positive energy balance, regenerative energy supply, CO² footprint and ecological criteria, examination of roof use as additional play area. The cost estimate (as of 07/2026) amounts to 4,088,444.56 € gross and is broken down as follows: KG 300: 2,950,537.50 € gross KG 400: 1,137,907.07 € gross. The subject of this tender is the planning services for the technical equipment for the systems 4+5 according to §§ 53ff. HOAI with the phases 1-9. Initially, a step-by-step commissioning will take place. In stage 1, phases 1-3 will initially be commissioned, in stage 2 phases 4-9. There is no legal entitlement to overall commissioning. The following schedule is planned: - Start of planning: May 2027 - Start of construction: 3rd quarter 2028
