Complex formwork solutions for high fair-face concrete quality
High demands on concrete surfaces and a tight schedule
There’s fair-face concrete wherever you look on the multifunctional extension of the production facility of the B. Braun Melsungen AG medical technology and pharmaceutical company at its parent site in Melsungen, north Hesse. For this project, the contractor Ed. Züblin AG, Stuttgart Region, is having to create top-quality concrete surfaces with a defined joint layout. The required custom forms are being designed wall for wall by Hünnebeck Project Development in Ratingen, approved by architects and then fabricated precisely to specification.
The composite building fabric (cast-in-situ concrete, partially precast slabs and steel structures) of the new production plant for infusion pumps and dialysis machines is to be erected in just 16 months. The complex comprises a production shop, workshops, clean rooms, laboratory, an office wing, a canteen and a multi-level parking garage. Some of the one- to four-story purpose-built building units have cellars, while others rest on ground-level foundations. Access to all areas is provided by six continuous staircases and various lift shafts.
The project will consume about 23,400 m³ of cast-in-situ concrete until its completion scheduled for September 2010. This means plenty of work for the fabric constructors who have to shutter roughly 60,000 m² of wall and slab surfaces. The foundations account for 3,700 m², the slabs roughly 12,000 m², and all this is joined by 6,600 m² of support for partially precast slabs, 1,000 m² of column formwork and 3,500 m² for floor bearers, upstand beams and parapets. These are tough formwork tasks for which Züblin is relying on planning services and materials from Hünnebeck.
