Würth Art Museum, Erstein, France
14 m high walls in architectural concrete quality
Modern architecture is making increasing use of visible concrete surfaces as design elements. In order to be able to fulfil the high requirements for the realization, plenty of experience and positive co-operation of everyone involved in the project are necessary. Attaining a high standard of architectural concrete is a team achievement comprising of architect, design designer, formwork specialist as well as the formwork crew and concrete manufacturer.
For the construction of the Würth Art Museum in Erstein/Elsass, up to 14-metre high reinforced concrete walls in fair-faced concrete quality were to be erected. For this, locally-based contractors, Dicker Construction, used the variable PERI VARIO GT 24 girder wall formwork. Together with engineers from the PERI branch office in Bernolsheim/Elsass, a formwork solution was developed which it made possible for the site crews to meet all requirements regarding the formlining joints and screw positions along with the execution and requested positioning of the anchor points.

We have worked with PERI formwork for over 15 years now and have always achieved good architectural concrete results. The systems are easy to understand and function well. In addition, PERI always provides immediate qualified answers and solutions to specific questions. The PERI VARIO system was the only choice for us with these high walls. The results fully meet the architect´s expectations.

The new art museum should be officially opened in autumn 2007. Owned by the globally-operating Würth Group, works from Emil Nolde and Max Ernst along with many contemporary paintings, drawings and sculptures will be exhibited on an area of 3,000 square metres. With this, Würth would like to bring art closer to its employees as well as the general public with the aim of increasing the quality of life and work including outside of the usual cultural centres.

The use of SCC self-compacting concrete and the large concreting heights made it necessary to configure the formwork system to handle a concrete pressure of 120 kN/m². High load-bearing PERI GT 24 lattice girders, installed with a maximum spacing of 20 cm, provided safe load transfer into the steel walers. After consultation with the architect, a uniform anchor grid of 120 x 85 cm was determined. Assembly of individual components to form complete movable formwork units took place on site. Logical assembly sequences and detailed construction drawings drawn up by the PERI engineers guaranteed that all work procedures could be accurately and quickly implemented by the experienced building site team. |

The up to 14.00 x 2.50 m large formwork elements were used around 30 times. When connecting the individual elements, the specially designed rows of slotted holes on the PERI steel walers together with the couplers ensured continuously flush and sealed element joints. |

For aligning the formwork and safe transfer of wind loads, PERI provided the contractors a perfectly co-ordinated solution from the PERI push-pull prop programme – and for all formwork heights required. PERI push-pull props RSS III, RS 1000 and RS 1400 were all used in this project. Sheer wall sections could also be temporarily supported with the PERI system equipment. |
