Yet, the workers had another trial in store for the new MEVA StarTec XT: instead of being stripped af ter one to two days, as normal, the formwork was left in place for three or four days over the week end. Here, the site team wanted to test how easy it would then be to remove the taper tie for fast, sin gle-sided tying without plastic tubing. It turned out to be no problem. Ernst Muser is also impressed by the range of panel sizes – heights of 330, 270 and 135 cm, and eight widths between 270 and 30 cm – and the symmetrical tie hole and joint pattern resulting from the internal tie positions.

An architectural gem for Budapest MEVA formwork for the construction of a church that is worth seeing

In the case of – a true architectural gem. For the intricate the Reformed Church’s new place of worship with design with high requirements on the quality its complicated monolithic load-bearing structure, of the concrete, the construction company the MEVA material chosen was transported to the Kész relied on flexible formwork systems from construction site: 200 m² of Mammut 350 panels, MEVA. 400 m² of MevaFlex, eight Triplex props, 80 EuMax props and eight MEP shoring towers. At the groundbreaking ceremony in 2019, Ákos Szabados, the mayor, talked about an “architectur Kész employed the Mammut 350 system to create al gem for Budapest”.

To obtain a reliable solution for pouring The over 50 m³ of concrete needed to cast the concrete onto the sloping form face and practical roof slab was reliably placed using the stable, on-site formwork assembly, the client drew on the lightweight MEVA32 tower shoring system. With a expertise of GFS. This entailed adjustment of the support capacity of 142 kN, the system is ideal for wall and slab formwork in line with the form face challenging applications involving high loads and inclination. The roof construction was built using elevated heights. the cost-effective MevaFlex slab formwork system, which is readily adaptable to any building With easy-to-handle components weighing max. geometry. 23 kg, the shoring tower can be quickly and easily assembled on the ground by a single person before being craned into position. Treading on the top of each cross bar further improves worker safety. The system is space-efficient and allows flexible assembly around the building's other structural elements so that plenty of working space remains at ground level.
Due to the frequent snowfall at this altitude in the Cordillera Mountains near the border with Argentina, provision was needed for a 25° roof

Underground impressionists Extension to Danish art museum cast with StarTec
Ordrupgaard Art Museum has been enlarged with a suitably engaging extension. The new addition, which will house the French Im- pressionist collection, is mainly underground. Its concrete shell was erected by contractor Ommen a/s using some 950 m² of StarTec formwork panels.
Built over a century ago near Charlottenlund north of Copenhagen, the Ordrupgaard estate originally comprised a mansion house with gallery, conserv atory, staff buildings and stables in a parkland setting. Today, Ordrupgaard evokes positive asso ciations among art lovers due to the like-named museum, which opened in 1953, and its extensive collection of mainly Danish and French painters that attracts visitors from near and far. All the more so since the inauguration, in 2005, of a modern extension designed by star architect Zaha Hadid. And now another remarkable exhibition facility has been added – albeit, for the most part, under ground.
Immaculately orchestrated pictures Unsurprisingly for Scandinavia, the appeal exert ed by the art on show at the Ordrupgaard is not limited to adults. A thrilling themed playground is provided for small children and an art park for teenagers. The valuable paintings, of course, are
