Germany – Construction work – Ausschreibung von Dachabdichtungsarbeiten - Hauptmaßnahme (Gewerk 321B) für den Neubau des AKK

The AKK plans to carry out renovation work on the building "Reha Aufstockung" at Bleickenallee 38 in Hamburg Altona, adding three additional storeys. The existing building is partially basemented, with technical rooms and changing rooms in the basement, and the ground floor will continue to be used as a rehabilitation facility. The Reha building is classified as building class 5 according to § 2 HBauO. The 1st floor of the extension will house a day clinic for partial inpatient treatment, which will serve as replacement space for the site clearance of the replacement new building I-Haus. The ward mainly includes examination rooms for diagnostic purposes and treatment rooms where patients receive infusions. Supporting rooms such as base, work and storage rooms, sanitary rooms and distribution kitchen complement the room offer. The three-storey extension will be constructed in reinforced concrete, consisting of load-bearing external walls as well as load-bearing walls and columns within the building. The ceilings will be planned as prestressed hollow core slabs with composite beams using prefabricated elements in composite construction. The external walls will receive a WDS system with brick cladding. The extension will have an extensively green roof with photovoltaic modules. The construction work is to be carried out while maintaining the ongoing hospital operation. Access to the construction site will be via Lisztstraße; all access routes to entrances and exits as well as fire and ambulance access routes must be kept clear at all times. The demolition and connection work must be carried out with this in mind.
