Public tender Vob/a heating systems and central water heating systems (DIN 18 380); the existing thermostatic valves (lower parts and upper parts) are to be replaced as hydraulically adjustable valves, the distribution in the technical room and its supply line from the heat exchanger to the distributor, as well as the new ventilation systems, are to be re-piped, some pumps are to be replaced and the district heating transfer station is to be completely rebuilt after the main shut-off units at the building entrance.

Public tender Vob/a Gas, water and drainage systems within buildings (DIN 18 381); Heating systems and central water heating systems (DIN 18 380); Air conditioning systems (DIN 18 379); The sanitary facilities of the Hofheim tax office, which were originally installed in 1991, are to undergo extensive renovation. This means that all toilets (men's, women's and disabled toilets) from the ground floor to the fourth floor as well as additional washrooms will be completely renovated during ongoing operations. In total, there are nine men's toilets, nine women's toilets, four disabled toilets and two washrooms in the basement and fourth floor. Due to a higher demand for the women's toilets compared to the men's toilets and some disabled toilets, which do not meet current standards, some toilets are being replaced. The Hofheim tax office is a multi-storey office building with a central access core that is divided into four parts (A, B, C and D). The contract includes the renovation of all toilets (tga Ag 1-3), the renewal of the entire fresh water supply (including tea kitchens and canteen/kitchen), the renewal of the waste water pipes (excluding underground pipes) and the renewal of the radiators and heating pipes up to the suspended ceilings in the rooms to be renovated.
