MevaDec: No Fixed Grid

Flexible in handling irregular slab layouts without a single right angle

Urban construction sites often battle with confined space and congested delivery access. This was the case when the Hôpital Cochin clinic in Paris was rebuilt and extended. 42.000 m² of slabs had to be poured on 5 levels and within a tight time schedule. What’s more, the site had to master irregular and constantly changing slab layouts without a single right angle.

This added up to a Formula 1 challenge for the MevaDec system. It is the only system that does not follow a rigid grid. The panels can change direction flexibly and compensation areas thus be reduced to below 20 cm. Site-built filler areas are thus minimised, saving time and labour. Forming around the large numbers of columns made this benefit very apparent. Using identical parts, the workers simply left out a panel and slid in secondary beams around the columns, on which they laid out wooden facing to fill the small compensation area.

The site also relied on MEVA’s shoring system MEP to achieve slab heights beyond 4 m and support the many concrete beams.
