LUMA: prefabrication in electrical distribution
The New Building project at the Parc des Ateliers d’Arles is a high rise dedicated to art, with exhibition rooms and studios for artists. It was ordered by the LUMA Foundation, whose patron is Madame Maja Hoffmann, who inherited the ROCHE pharmaceuticals group.
The structure designed by architect Frank Gehry stands out in every way: magnificent materials, eccentric shapes – 11,000 steel boxes, all different, cover its facade – and meticulous attention to detail. The architecture has the same originality, quality of construction, and excess as the Louis Vuitton Foundation building in the Bois de Boulogne.
Olivier Giraud heads the project for Santerne. He is used to major and export projects, having worked at SNEF before joining VINCI Energies.
In an exhibition room with a very high closed ceiling (about nine metres under the slab and seven metres under the false ceiling), Olivier talks about one decision that was taken during construction. DALI lighting, power outlets and RJ45 connectors needed to be installed in the huge 1,000 sq. metre artwork exhibition space.
To limit wiring errors and non-conformities, which are difficult to correct in a room with such a height, SANTERNE decided to install flat cable to distribute three-phase current and the DALI bus to which WIELAND pre-connectorised antennas are clamped. The cables are factory-tested to help ensure the “Get it right the first time” guarantee. The solution’s purchase price is probably higher – if one disregards the cost of correcting errors of conventional wiring errors, which are almost inevitable in such a large room. It took two people five days to fit out the 1,000 sq. metre space. This solution will be used in all the tower’s exhibition rooms.
