| PERI on the BBI airport site  The airport Berlin Brandenburg International is one of the largest traffic infrastructure projects under construction in Germany as well as currently being the biggest airport development project in Europe. BAM Deutschland AG is responsible for the structural work of the passenger terminal with a scheduled construction period limited to only twelve months. PERI was commissioned by the contractors to plan and supply the formwork and scaffolding systems, and impressed with expert engineering along with the delivery of large quantities of materials in a very short space of time.Reinforced concrete work on the airport site began in July 2008 and a total of around 200,000 cubic metres of concrete for the terminal is required to complete this phase. For this, PERI supports the site personnel with different system formwork taken from its extensive product range which includes enormous quantities of slab, wall and column formwork. The PERI brief also features planning and supply of corresponding supports and shoring. The, in part, enormous peaks in demand for system equipment is covered by the PERI rental park - optimized to suit the on-site material requirements and strictly controlled in relation to the tight schedule. The short construction period specified by the client has also resulted in PERI having to meet challenging deadlines for the technical processing. In close co-ordination with BAM Deutschland AG, more than 400 formwork and assembly plans were created in the space of six months by PERI engineers, two PERI engineering offices were involved in the planning. This close co operation as well as the high availability of materials demonstrate - among many other aspects - the broad range of expertise provided by PERI. The foundations and walls of the buildings are formed with TRIO panel formwork. The standard storey height of the wall sections is 3.75 metres, with wall thickness up to 80 centimetres. The proven and fast panel formwork system can be easily adapted to the different wall thicknesses and ground plans. For constructing the columns with cross-sections of up to 60 x 60 centimetres, the systems QUATTRO and RAPID are being used. The majority of the columns at the BBI are square-shaped with 80-centimetre side lengths and heights of six metres. These columns are formed with the VARIO GT 24 column formwork. Most of the slab areas must be concreted in one pour together with the main and secondary beams due to the static system that has been selected. For these areas, the construction crew uses various formwork and shoring systems as well as panel formwork elements. The slab tables along with the column formwork are pre-assembled by PERI as transportable units and delivered directly to the construction site. Due to the huge quantities of materials and short-term delivery deadlines, various PERI branch offices co-operated closely together for the assembly work: slab tables and formwork elements were prefabricated in Berlin, Leipzig, Hamburg as well as in Weissenhorn which is also responsible for the overall coordination. In order to ensure fast construction progress, almost 2,000 modular tables as well as more than 700 customized slab tables - designed together with BAM Deutschland AG - are currently being used for the project. In addition, the SKYDECK system formwork minimizes crane requirements as the individual components of the aluminum panel slab formwork weigh a maximum 15 kg. write your comments about the article :: © 2009 Construction News :: home page |
