Project: Conversion and Extension of Merkurcity with car park, Wiener Neustadt, Austria
Contractor: Granit Bau GmbH, Graz, Austria
Principal: Rutter Immobiliengruppe, Vienna, Austria
MEVA systems: Mammut wall formwork, AluStar wall formwork, MevaDec slab formwork, MevaFlex slab formwork, MEP props / shoring Towers, Circo circular column formwork, LAB working platform, MEVA FormSet safety mesh, Special formwork
Engineering and support: MEVA Schalungs-Systeme, Pfaffstätten, Austria
Ramps, architectural-concrete walls and ceilings, numerous concrete beams, rectangular and oval columns, rounded outside corners and bevelled inside corners. During the conversion of the 20-year-old Merkurcity shopping centre including the construction of a new 3-storey car park with 5,000 m² per level and 600 parking spaces, building sections with different geometries had to be poured without impairing the day-to-day business of the shopping centre. MEVA provided the ideal solution.
Architectural concrete without post-Treatment
The architectural concrete quality required for the walls, soffits and columns was achieved effortlessly using the alkus all-plastic facing of our wall and slab formwork systems and Circo steel facings. Post-Treatment was – as specified – not necessary. The rectangular columns were formed using Mammut panels, and the oval ones using additional Circo half-shells. They match the height of the Mammut panels and can be quickly and securely connected using M assembly locks.
The challenge of forming concrete beams
The numerous concrete beams for the ceilings have different dimensions and heights. The challenge for the formwork planner was to skilfully combine the slab formwork with the formwork and panels that were used to pour the concrete beam – not an easy task when there are varying geometries. The concrete beam was always formed first using MevaFlex formwork supported by MEP shoring towers, and then the slab formwork was attached using either MevaDec or MevaFlex in the filler areas. The MEP props were combined with reinforcing frames to form MEP shoring towers. “The MEP shoring towers are absolutely stable. This is a must”, confirmed foreman Rudolf Friedrich and site manager Patrick Ritz.
Quick and cost-effective
The MevaDec drop-head-beam panel method allowed early stripping and rapid reutilisation of the Panels and beams. Square timbers, Special formwork and cut-to-size or bent forming faces including alkus were only used to form rounded and bevelled corners. Otherwise standard MEVA formwork systems were used throughout to keep the costs down.
