ComFlor® selected for multi-purpose redevelopment in Central Amsterdam
ComFlor® composite floor decking is being used extensively in a major multi-function redevelopment of the former Catholic Ymere Chassé Church in Chasséstraat, within Amsterdam’s fashionable De Baarsjes neighbourhood, near to the City Centre.
The building was acquired by businessman Lenny Balkissoon in early 2011, with the goal of creating a cultural centre with a focus on dance. It is currently being transformed into a very diverse activity centre, four different dance studios, a hotel and gymnastics hall, to be used by local primary schools.
Although the original outer building skin has been retained, a completely new steel-framed structure, installed by Tambach BV and featuring ComFlor® composite floor decking, has been installed as an integral component. Its lightweight characteristics have eliminated the need for the expensive foundation work associated with a pre-cast concrete solution.
ComFlor® 210 is being used on the ground floor, which will house a large ballroom. The original SlimFlor long span steel deck, ComFlor® 210 has the capability to span up to 6 metres in unpropped construction.
It is suitable for use in Tata Steel Slimdek® construction, which offers minimal structural depth, fast construction and many other benefits.
With cross and longitudinal stiffeners, ComFlor® 210 is structurally efficient and offers excellent composite action with the concrete. Simple single bar reinforcement in each trough, combined with anti-crack mesh near the top of the concrete slab, gives the composite slab superb structural strength and fire properties. The nestable profile shape reduces transport and handling costs.
ComFlor® 80 has been selected for the first floor hotel rooms. It also features on the second floor, which will be home to the gymnastics hall.
ComFlor® 80 is the next generation of profiled steel composite decks. It is the only 80mm profile available in Colorcoat® pre-finished steel to provide a durable and attractive appearance.
The large corner curvature detail provides a very efficient profile. In conjunction with the higher grade of steel, it ensures typical unpropped spans of 4.4m simply supported and in the continuous condition, spans of 5m can be achieved.
The large spans achievable means less structural steel and thus cost saving in the overall construction cost, providing more scope for architects and engineers in their design process.
The initial phase of the project is expected to be completed during Summer 2013.
