More Expansion of the classrooms for the Kurt Schumacher School in 61184 Karben, as well as construction of the outdoor facilities Provision of general planning services (architectural and specialist planning services in accordance with the contract notice) for the expansion of the classrooms for the Kurt Schumacher School in 61184 Karben, as well as construction of the outdoor facilities. Expansion of the classrooms for the Kurt Schumacher School in 61184 Karben, as well as construction of the outdoor facilities Title 1: "Expansion of the classrooms" As part of the "Expansion of the classrooms at the Kurt Schumacher School in Karben", a barrier-free new building with an elevator system is to be built. The attached overview plan Represents the current development, with the new building only being shown as an example. The location of a suitable site on the school premises must be examined. A feasibility study is to be prepared for this in performance phase 1. Under certain circumstances, it will also be necessary to prepare a site analysis following a decision by the developer. The layout on the site should, if at all possible, be chosen in such a way that no additional schoolyards are created, but that as central schoolyard areas as possible remain so that supervision during recess times can be guaranteed as before. Possible location on the site It is conceivable that the area between the old building and the main building will be used as a site. For this it will be necessary for the classroom building (e-building), adjacent to the old building, to be demolished. For the planning and implementation of the demolition work, if necessary, the special service "participation in the awarding of planning and expert services" has been integrated. The same applies to the relocation of the green classroom in the area of this construction site to a suitable location on the school premises. A structural connection to the existing main building and, depending on the specified location, the old building is conceivable and must be examined, particularly with regard to fire protection issues and fire protection concept (taking into account the connected existing buildings). If a connection between the main building and the old building makes sense, this must be implemented. The same applies to a possible integration of existing buildings. The aforementioned services were therefore included as an option. From a technical point of view, a connection is to be preferred. Project goal: The goal of the functional, compact extension to the Kurt Schumacher School is, in terms of quality, to construct an ecological building that, among other things, offers a pleasant learning atmosphere even in the increasing summer heat without the installation of air conditioning (for a healthy room temperature, according to the Workplace Ordinance IVM the Technical Rules for Workplaces (asr), points 4.3 and 4.4, suitable sun protection measures must be taken at room temperatures above 26 degrees Celsius). Central or decentralized classroom ventilation is optionally possible. The type of ventilation to be used is decided by the client after testing/recommendation by the specialist planner in the project. Furthermore, the management costs, particularly those related to the cost drivers of cleaning, janitorial services, heat, electricity, maintenance (taking into account any damage caused by vandalism during school operations) and servicing over the life cycle of the building (construction phase, usage phase: 50 years, disposal phase), should be reduced or minimized to the bare minimum. When planning and executing the project, economic efficiency must always be taken into account. The project must be planned within the client's budget (total expenditure required). Architectural designs that conflict with the "functional and compact construction" requirement are not desired. Additional costs should be avoided and materials and equipment should be planned to a good standard (no high-end design) in order to avoid unnecessary costs. Changes to the order are possible if they are requested by the client and confirmed in writing and if they do not change the overall nature of the order. Please refer to Appendix 01_project description for further information.

Competition notice – general guidelines, competition open procedure (services) 122024_kha In terms of its possible uses, the port area in Kassel has so far benefited neither from its proximity to the Fulda and the urban-spatially interesting port situation nor from the surrounding landscape. There is a considerable need for urban development action to activate the potential for new development and revitalization of the port area. Due to dominant commercial and large-scale uses and building structures, the port area currently has no effective urban attractiveness or charisma. The almost non-existent accessibility to the port and the Fulda reinforces this. Fortunately, the large property owners located in the competition area have expressed a willingness to change the use and structural development of their properties. The competition is intended to provide a qualified basis for this willingness to develop. The competition area has a size of around 11.0 hectares. Of this, around 1.7 hectares of private green space with integrated nautical uses are to be designed as part of the ideas. The aim of the implementation competition is to develop a dense urban district and its future-proof development, taking into account framework concerns such as monument protection or climate protection and climate adaptation requirements. The two-stage process serves to facilitate communication and exchange between various experts, the owners, the public and potential investors. This is intended to make it clear to the owners, even without planning knowledge, what positive developments in urban development and building construction are possible at this location. The competition is intended to develop solutions that meet the expectations at different stakeholder levels (city and owners). The competition is also intended to create a binding basis for cooperation between the city and the owners, so that they can participate reliably and significantly in the development of the area. A qualified development of the port area is also intended to support the transformation of the neighboring "co-op quarter" that has already begun and to continue the upgrading of the quarter that is currently underway in the area around the harbor basin. The process therefore creates the basis for possible future development, which is to be secured under planning law by the seamlessly subsequent development plan process. This development plan and a design manual are the contract promise that results from the open urban development and open space planning competition and the subsequent negotiation process. 122024_kha Evidence of suitability in the negotiated procedure: In order to be admitted to the negotiated procedure, the following suitability criteria must be proven: 1_proof of professional liability insurance, but at least the informal declaration of an insurer, of the following coverage amounts in the event of an order: at least EUR 3 million for personal injury and EUR 0.5 million for other damages (maximized twice). 2_name of at least 2 technical employees (architect/urban planner) and 2 technical employees (landscape architect) with qualifications corresponding to the eligibility to participate. 3_proof of development plan §§ 19 and 21 Hoai 2021: proof of at least 2 development plan procedures carried out in the last 10 years (lph 1-3). 4_naming of traffic planner: naming of the traffic planner with whom the contract is to be worked on (for competitive reasons, a traffic planner may only be a member of one group of bidders in the negotiation process). 5_declaration of the authority of the authorized representative. A bidder can use other companies to demonstrate their performance and expertise, regardless of the legal nature of the relationship between them and this company. If the bidder uses the capacities of other companies as part of a loan of suitability with regard to criteria for economic and financial performance, these must be jointly liable for the execution of the contract in accordance with the scope of the loan of suitability. Award criteria The negotiations will be carried out with the 3-5 prize winners in accordance with Section 14, Paragraph 4, Item 8. An evaluation committee will be formed to evaluate the revised drafts and the bidder presentations on the basis of the award criteria specified in advance. The composition of the committee corresponds to that of the jury of the preceding competition. The committee's working methods are based on the working methods of a jury in a competition procedure. If commissioned by the awarding authority, the bidders undertake to take over and carry out further processing. The commission is subject to the committee's approval. The award criteria in the negotiated procedure will be: 1. Evaluation of the design 50% 2. Order-related composition of the planning team 15% 3. Organization chart + key personnel 15% 4. Project organization 15% 5. Fee offer 5%. Commissioning: When the selected design is implemented, one of the bidders will be commissioned with the further planning services, taking into account the evaluation on the basis of the award criteria, unless there is an important reason to prevent the commission. The following services are part of the contract award based on the Hoai 2021: 1. Update of the urban development and open space planning concept of the competition design (informal planning) 2. Development plan Lph 1-3 §§ 19 and 21 Hoai 2021 incl. accompanying plans 3. Design manual with elaboration and concretization of the in-depth areas A.
