Germany – Engineering design services for mechanical and electrical installations for buildings – Max-Planck-Institut für Gravitationsphysik, Hannover Umbau und Erweiterung Gebäude 3405 - „Fachplanung Technische Ausrüstung (ELT)“

With the start of planning, the public access for the telecommunications connection should be considered as appropriate. Possible redundancies and the connection of further institutional buildings (campus networking) should be planned as needed. The Max-Planck-Institut für Gravitationsphysik in Hannover is connected to the public network via the MS – handover station in the Callinstraße. The medium-voltage system is located as a customer station in the basement of building 3405. From this station, 3 transformers with the following connection values are supplied: 1600 KVA via circuit breaker, 1000 KVA via circuit breaker, and 630 KVA via HH fuse switch. The 1600 KVA transformer is separately isolated and supplies a server system (cluster) with its own NSHV in the transformer cell. The aforementioned systems are to be designed for the future power requirements of the institute and must be adjusted to a common power level. For the conversion of the transformer systems, an interim supply must be created to fully maintain the institute's operations. Particular attention must be paid to ensuring that downtimes are kept to a minimum. The need for an emergency power supply SV must be considered depending on regulatory requirements (sprinklers, mechanical smoke extraction, etc.). Special note regarding tender questions due to special external events (e.g. SARS-COV-2 or Ukraine war): Please consider any possible or recognizable impairments in your offer, e.g. with regard to the availability of materials and products, workforce, a possible delayed submission of required evidence, effects on any subcontractors, etc. Questions arising in this context, we ask to be submitted in good time before the deadline for submission of tenders via the news system of the eVergabe.
