Preliminary information as a call for competition – general guidelines, standard regulations (services) General planning service Hoai for the expansion of the 2nd biological stage 1. Initial situation The Sindlingen sewage treatment plant has currently been expanded to include 4 aeration tanks and 3 secondary clarification tanks. Contents of the project are: planning and construction of 2 aeration tanks and 1 secondary clarification tank, as well as the integration of these tanks into the existing structure. 2. Description of the project 2.1 New aeration tank The aeration tanks are rectangular tanks with longitudinal flow. Their internal dimensions (LxWxH) are approximately 59.6x11.6x5.0m. An underground distribution channel runs along the northern front of the four existing aeration tanks. Next to a large wastewater area, a smaller channel for the return sludge is installed. A pipe branches off from each of these two channels to feed the aeration tanks. These pipes cross an open space in front of the aeration tank that is approx. 5.3 m deep and covered with grid plates. There is a manually operated slide valve, a flow meter and an electric slide valve for each pipe string. The wastewater now crosses the tanks lengthways. The air distribution line runs through 3 separately controlled areas and is led downwards in the middle of each zone. At the southern end of the tank, the wastewater falls over an overflow edge into a collecting channel. The channel directs the wastewater via a distribution structure to the secondary clarifiers. 2.2 Distribution structure The channel leads from the outlet of the aeration tanks via a coagulant addition to the distribution structure. The wastewater is then led via a siphon into a round spring pot. The source tank is divided into three equally sized drainage areas, which then lead to the respective secondary settling tanks. 2.3 New secondary settling tank The secondary settling tanks are designed as round tanks. The wastewater is led from the distribution structure into the secondary settling tanks via underground pipes. It flows into the middle of the tanks. The drainage channel is suspended on the edge of the secondary settling tanks. The clear water can flow into the drainage channel on both sides. It is fed to the further treatment steps via a collecting line. The round tanks have a bottom clearing shield and a floating sludge scraper. The settled sludge is led via the bottom clearing shield into the middle of the tank and from there via a collecting line to the screw pumping station. There it is lifted and returns to the aeration tanks by free fall. The floating sludge is led via pumps on the secondary settling tank in a separate line towards the return sludge pumping station. Two centrifugal pumps lift the floating sludge there. 2.4 Connections and integrations The required inlet and outlet channels to and from the planned basins must be provided. In particular, the distribution structure must be examined in detail to clarify whether a new construction or an extension of the existing structure is possible. The electrical components required in each case must be integrated into the existing switchgear and the control panel extended. The vertical distance between the aeration basins to be planned and the switchgear is around 90m as the crow flies. The distance between the secondary clarification basin to be planned and its switchgear is around 200m as the crow flies. Additional content is the planning and construction of a new service road around 240m long. The creation of an accompanying landscape management plan in conjunction with the Hessian compensation ordinance is also part of this project. 2.5 Tests and simulations At the start of the measure, the existing structure is to be recorded and tested. The results of this will then be incorporated into the further planning of the new structures to be built. The hydraulic cross-section must be checked and revised in accordance with the planning. The return sludge pumping station and the air supply to the aeration tanks are to be tested for their capacities in order stage 1. Various load scenarios are to be represented by a simulation. No further planning is being carried out for the return sludge pumping station and the air supply. Flow simulations are to be carried out using CFD for the existing inlet channels, including the new ones to be built, to the aeration and secondary clarifiers, in particular the distributor structure. Three load cases or operating states to be determined by the SEF are to be simulated. A preliminary test in accordance with Uvpg §5 Paragraph 1 Number 1 is required for the planned expansion of the Sindlingen wastewater treatment plant. Whether this results in the requirement for a formal EIA depends on the results of the preliminary examination. 3. Planning services according to Hoai 2021 The following service descriptions, special and additional services are to be carried out. According to Hoai §11 (1), the fees for each object are to be calculated separately. 3.1 Hoai service descriptions Landscape management accompanying plan according to §26, §31 para. 1 in conjunction with Appendix 7 Hoai object planning for civil engineering structures according to §41ff.; §44 para. 4 in conjunction with Appendix 12 Hoai object planning for traffic systems according to §45ff.; §47 para. 2 in conjunction with Appendix 13 Hoai specialist planning for structural planning according to §49ff.; §51 para. 5 in conjunction with Appendix 14 Hoai specialist planning for technical equipment according to §53ff.; §55 Paragraph 3 in conjunction with Annex 15 Hoai 3.2 Special services are commissioned across all service profiles with the following breakdown: - Commissioning level 1: approx. 20% - Commissioning level 2: approx. 50% - Commissioning level 3: approx. 85% The full range of special services is defined in the tender documents 3.3 Additional services Various additional services, such as: - BBQ acc. to DIN 1054 - On-site construction monitoring - Geotechnical investigations The full range of additional services is defined in the tender documents 4.

Multi-object planning for a building for the extension of the Otfried-Preußler-School, Dillenburg Object planning for a building for the extension of the Otfried-Preußler-School, Dillenburg Object planning services for buildings in accordance with Part 3, Section 1 HOAI, LPH 1-9 for the extension of the Otfried-Preußler-School, Dillenburg. The district committee of the Lahn-Dill district, represented by the building department - schools, is the sponsor of schools according to the Hessian school law. In this capacity, it is planning the extension of the Otfried-Preußler-School in Dillenburg. The Otfried-Preußler-Schule was built in 1974 and has since been a special needs school with a focus on intellectual development and a department for physical and motor development in Dillenburg in central Hesse. The school currently has around 131 pupils in grades 1 to 10 in 19 classes. Due to the steadily increasing number of pupils and a lack of classroom space, two primary school classes have been taught at the Donsbach primary school since the 2021/2022 school year; in the 2022/2023 school year, further classes were relocated. The current project is intended to supplement the range of classroom space and enable the reintegration of the relocated school classes. In order to be able to optimally reflect the school's space requirements, a feasibility study for the extension/new building was drawn up in May 2022. The existing floor plans of the Otfried-Preußler-Schule and variant 5 from the feasibility study by the architectural firm Freischlad + Partner, Haiger, as of May 2022, are attached to this document for information. The planning services in question for the building project planning are awarded as a staged contract. It is intended to initially commission service phases 1 to 4 for the overall project.
