Germany – Construction work – Ausschreibung von Außenfenster; Außentüren (Gewerk 326B) für den Neubau des AKK

The AKK plans to carry out renovation measures on the site at Bleickenallee 38 in Hamburg Altona to add three additional storeys to the building "Reha Aufstockung." 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 care, which will serve as replacement space for the site clearance of the replacement new build I-Haus. The ward primarily includes examination rooms for diagnostic purposes and rest rooms where patients receive infusions. Supporting rooms such as base, work and storage rooms, sanitary facilities and distribution kitchen complement the room offer. The three-storey extension will be constructed in reinforced concrete, consisting of load-bearing external walls and load-bearing walls and columns within the building. The ceilings will be planned as post-tensioned hollow core slabs with composite beams using prefabricated elements in composite construction. The external walls will receive a WDVS system with brick slip 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 operations. Access to the construction site will be via Lisztstraße; all access routes to entrances and exits as well as fire and ambulance vehicle access routes must be kept clear at all times. The demolition and connection work must be carried out with due regard to this.
