ETH Zurich, HCI, BKP 347 steam installations, extension of the RCHCI washing hall

Initial situation and overarching objective ETH Zurich operates animal husbandry for laboratory activities in the HCI wing on the Hönggerberg campus. For animal husbandry, the RCHCI has a washing hall with the necessary equipment for cleaning and processing materials for animal husbandry. In the future, animal facilities for laboratory work will be set up on the Irchel campus for the planned Neuroscience Cluster. The cleaning and processing of these materials is carried out in the existing washing hall in the RCHCI on the Hönggerberg campus. ETH intends to renovate and expand the EPIC rooms. As part of GMIS application 1319447, the existing washing hall will be expanded with a rack washer, a drive-through autoclave and a bottle filling machine and the existing autoclave will be replaced to ensure operation. Adaptation and renewal of the existing steam supply to ensure the required operating conditions for the new systems (autoclaves, rack washers) as well as adaptation of the associated steam and condensate installations. Due to the interventions in existing systems, effects on adjacent operational areas must be taken into account. This includes: - Steam pipes and condensate pipes in accordance with the specifications, including the necessary adjustments to the existing installations. - Condensate connections, where necessary, with mixing nozzles. - The previous DN 80 reserve connection on the steam distributor is now used for the steam supply. After the installation work, the previous “autoclave” DN 65 and “dishwasher” DN 50 consumer connections will become reserve connections. - Instead of individually arranged sterile filters, two parallel sterile filters are installed on floor C for all supplied consumers. These are operated in parallel during normal operation. When changing the filter, the entire amount of steam can also be passed through a filter. - Delivery and assembly of the items specified in the list of services
