Germany – Engineering services – Lebenshilfe Bad Dürkheim e.V. - Sanierung Therapiebecken inkl. Schwimmbadetechnik in der Siegmund-Crämer-Schule, Los 2 - Planungsleistungen der Technischen Ausrüstung HLS und Gebäudeautomation

Lebenshilfe Bad Dürkheim e. V. intends to renovate the therapy pool, including the associated swimming pool and building technology, in the Siegmund-Crämer-Schule, Sägmühle 4, 67098 Bad Dürkheim. The swimming hall is part of the main building of the special school. The building, constructed in the mid-1990s, is made of solid construction with a rear-ventilated wooden facade. The swimming hall area is located in building section A and is partially basemented. The focus of the measure is the comprehensive renovation of the existing therapy pool. The pool will be completely lined with stainless steel. The existing jet nozzles will be replaced by floor channels. The area below the subsequently installed steel platform will be concreted, thereby simultaneously reducing the volume of water to be cleaned and heated. In addition, comprehensive renovation of the building envelope in the area of the swimming hall is planned. The existing post-and-beam facade, including glazing, will be renewed due to its condition and for energy efficiency improvements. The northern facade will be fully closed and constructed in solid construction. On the southeast side, a post-and-beam facade with fixed sun protection is planned again. An emergency exit ensures escape to the outside. A further essential part of the measure is the renewal of the technical systems. The swimming hall, including changing and shower rooms, as well as the technical rooms in the basement and first floor, will receive a new ventilation system. For this purpose, among other things, control and shut-off valves for the drinking water supply will be retrofitted in the ceiling areas in the changing and shower rooms on the ground floor. The heating of the swimming hall will in future be carried out exclusively via the new ventilation system. The previously joint air supply of the swimming hall as well as the shower and changing area will be separated in order to meet the different temperature requirements of the usage areas. A new compact ventilation unit with heat recovery is planned. This will supply the technical area in the basement and the shower and changing area with supply and exhaust air. A separate ventilation unit is planned for the swimming hall. In addition, the new installation of a control, monitoring and control system for the technical systems is planned. The existing drinking water network will remain essentially unchanged. In particular, new shower and washbasin fittings, control valves and smaller adaptations for the retrofitting of sampling and safety valves are planned. The existing wastewater pipes will also remain basically unchanged. The existing hot water heater in the technical centre in the basement will be relocated. In the technical centre in the basement, the drinking water pipe routing will be adapted to the new location of the hot water heater, including new shut-off fittings for the connection. The heat distribution network for building heating will not be renewed or modernised. The heat distribution network within the heating centre/technical centre in building section A in the basement of the property will be adapted due to the relocation of the hot water storage tank. The heat distribution network within the technical centre on the first floor will be adapted due to the new ventilation units. Existing, non-controllable heating pumps on the heating circuit distributor in the technical centre in the basement will be renewed. New heating pumps and control fittings are planned for the ventilation system on the first floor. Since the heating of the swimming hall will be carried out exclusively via the new ventilation system to be installed after the renovation, the radiators in the swimming hall will be dismantled. The heating connections will be dismantled back to the technical centre and sealed. A DDC for control is planned for the building, which covers the basic functionalities of the building services systems in the technical centres. Further building services systems in other building sections will not be connected to the new control technology as part of these measures. A switch cabinet will be provided in the technical centre in the basement. A switch cabinet will be provided in the technical centre on the first floor. The connection between the switch cabinets will be made via BUS technology. For the control system, remote access and a fault message forwarding with a GSM module are planned. New temperature sensors for heating and drinking water are planned for the technical centres. The new energy-saving heating pumps will be controlled via the new control system in the technical centre in the basement. The planning services required for the measure have already been provided up to and including phase 3. The subject of the current tendering procedure is the continuation of the planning from phase 4. For details, reference is made to the scope of services.
