The steel reinforcement is currently being installed and the connection and installation lines are currently being installed on the prefabricated composite ceilings. The pipe hoses for the concrete centre activation are already being inserted into the lower reinforcement layer of these ceiling panels. The distributors for the concrete centre activation are proactively positioned in the future sanitary facilities or in the storage rooms of the individual residential properties to ensure accessibility and efficient distribution of electrical energy. If no precast components are required, the balcony slabs are also concreted at the same time as the corresponding floor slabs. The prefabricated walls of the individual floors and the intended plant trays on the balconies are being installed at the same time as the different floor sections are being completed. In the basement, the sewage water pipes are already being installed by the plumber.
