Project: Corporate headquarters with entrance hall and staircase
Owner: AUMA Riester GmbH & Co. KG, Müllheim, Germany
Contractor: Moser GmbH & Co. KG, Merzhausen, Germany
Formwork Engineering: MEVA Formwork Systems, Germany
Müllheim in southern Germany is the home of AUMA Riester GmbH & Co. KG, a mechatronics specialist. The company is building new headquarters with unique architectural features. One of them is a uniquely shaped and rounded concrete staircase that will be the highlight of the entrance hall. The stairs themselves revolve upward irregularly around a tulip-shaped inside core.
The challenge facing MEVA engineers was translating the architect’s 3D model into a buildable and realistic plan in the first place. First they split the staircase into eight separate units, then worked out an exact pour plan for each.
Following this, each unit was separated into formwork sections which were planned in CAD and handed over to special designs production company Kiefer Schalungsbau, from where they were delivered onto the site and assembled. Thanks to the exact pour outline and workflow planning for each unit, the site was able to start with the concrete pours without any delay.
The centurion staircase, as the architectural gem was lovingly called, was finished on schedule and to the approval of architects, contractor and owner.

High, Fast, Safe: A state-of-the-art biopharmaceutical production plant is being built for the US biotechnology company Biogen, located on the grounds of a former paper factory in Luter bach near Solothurn, Switzerland.
One of the latest thrills: Float like a bird at a skydiving center, where an artificial airstream will keep you up in the air.
The solution: table forms, 5.40 m long to exactly fit into the openings between the columns. Short filler pieces with rounded edges provided a perfect match to the column layout.
