SUPER-RS scaffolding on high-rise administration building in Hamburg
The main administration building of the Berufsgenossenschaft für Gesundheitsdienst und Wohlfahrtspflege - BGW - (Employer's Liability Insurance Association for Health Services and Welfare Care) in Hamburg is currently being modernised as part of an energy-related facade refurbishment including gutting and removal of the top floor. The over 50 m high building from the 1970s was scaffolded by the long-established company AGB Alster Gerüstbau GmbH & Co. KG from Hamburg. A special feature here: the scaffolders used the new SUPER-RS modular facade scaffolding from the Westphalian manufacturer Scafom-rux for the two narrow sides of the building. This system has already integrated the advanced guardrail required by the regulations of TRBS 2121. However, according to the manufacturer, this allows the continued use of existing components such as scaffold decks and brackets. Since Alster Gerüstbau has been working with the SUPER facade scaffolding system for decades, these investment advantages were very well received by Managing Director Tanja Künne, according to her own statement.
The scaffolding consists of a total of approx. 5,250 m2 of facade scaffolding, of which 3,600 m2 are made of SUPER-100 and the remaining 1,650 m2 of the new SUPER-RS scaffolding material. The structure was completed using 0.30 brackets. Access is via 2 stair towers, each 54 m high, as well as 2 GEDA scaffold lifts, type 1200 Z/ZP. The entire construction was fixed with V-anchors and completely equipped with nets. The service life of the scaffolding is estimated at 42 weeks.
According to scaffolder Danilo Kempcke, who planned the scaffolding together with the engineering company Tomshöfer und Partner, Alster's scaffolders got on very well with the new scaffolding system: "Although it is a dissolved scaffolding system with standards and decking bars instead of complete frames, no time delay was noticed in the pace of construction compared to the frame version." The lower weight of the individual components compared to the fixed frames of a facade scaffold was also positively received.
The technicians from Hagen sent by Scafom-rux to support the new scaffolding system in northern Germany were equally satisfied with the problem-free assembly by the Alster employees. Tobias Burandt from Scafom-rux: "With the colleagues from Alster, you notice straight away that they can hardly wait to use the new material for more complex scaffolding situations in the near future. There are creative minds at work!" Tanja Künne also sees this creativity of her 20 employees in coping with a wide variety of scaffolding requirements as the cornerstone of Alster Gerüstbau activities. She is now the second generation to successfully run the company, which was founded in 1995 by her father Harald Müller. Alster is primarily active in the greater Hamburg area as well as northern Lower Saxony and Schleswig-Holstein.
