Elioth forms a team of fourty people within the Egis group. Just as Bourbaki sought to reformulate modern mathematics, we firmly believe that ecological emergency combined with the power of computer tools naturally leads to a revolutionary re-thinking in matters of engineering approach and design practice. There is no doubt in our minds that the trilogy engineer-designer-inventor has not only a role to play but also a duty toward society and the planet [...]

Inauguration of the Velodrome Stadium in Marseille

On Thursday, October 16th, 2014, the retrofitting of the Velodrome stadium in Marseille will be completed and its grand opening will be celebrated by all those who took part along with many VIPs.

The Velodrome Stadium is the second of three stadiums to be designed by Elioth for the Euro 2016 games after the Allianz Riviera which officially opened last summer and the Geoffroy Guichard stadium, in the town of Saint Etienne. This project was an adventure that started 5 years ago during which Elioth worked along side the consortium formed by Arema/GFC/SCAU/EGIS offering its expertise when it came to the steel structure of the roofing, cladding and environmental issues.

Given that is was an extremely complex project, not only due to the form of its geometry, but also the fact that the different constructions phases took place while the stadium was still in activity, in addition to being located in an earthquake zone and  on the seafront, it leaves one awestruck by its impressionable overall dimensions :

-   Roof dimensions 280 x 210m
-   Roof Area in PFTE tensile fabric:  45 000m2
-   Steel Tonnage  5 000t
-   Cost of works: over € 260M

For Elioth the stadium especially meant the implementation on a large-scale of parametric geometric modeling tools such as Rhino and Grasshopper in conjunction with the finite element software (GSA via SSI and also Ecotect). Beyond the software tools, Elioth and Scau’s joint design for the roofing and the cladding resulted in an envelope of which the structural design was not only true to the architectural vision but was built for maximum efficiency.

After four years of construction the stadium is now fully revealed and one that Elioth can be extremely proud of; it is one of the  best  examples to showcase  our technical expertise.

Urban strategy & prospective

Elioth at the AAG conference

Elioth shall submit its work at the Advances in Architectural Geometry conference to be held in London from the 18th to the 21st of September.

It introduces an algorithmic method that can be used in order to automatically optimize large spanning truss structures, such as stadium roofs and other large steel frameworks and used for the FFR stadium roof design.

IABSE Conference in Freiburg

Elioth submitted its design work on the ETFE envelope of the Allianz Riviera Nice stadium at the IABSE (International Association for Building and Structural Engineering) conference held in Freiburg in june of this year.

Multi-media regional library of Caen

The work on the site of the multi-media regional library in the town of Caen is progressing: major structural works and the steel structure of the 1st floor are underway.

Discover a prototype of the consultation area façade which is made up of very high, curved, complex glazing in structural glass: This major structure, the first of its kind in France, presents technical and architectural prowess which allows to reinforce the harmony of the façade, gain in transparency as well as offering more available indoor space thanks to the suppression of glass stiffeners

International Forum on the Renewable city

Venez découvrir les résultats des travaux de recherche du programme Interdisciplinaire  « Ignis Mutat Res : l’architecture, la ville et les paysages au prisme de l’énergie » (IMR) qui seront présentés lors du forum international sur l’énergie renouvelable et la ville, les 10 et 11 juillet 2014, à Versailles.

Jeudi 10 juillet à 14h30 :

Raphaël Ménard animera la table ronde : “Profiter de la solarisation des territoires”,  en compagnie de Marie Jorio, directrice opérationnelle Nanterre La Garenne-Colombes et de la coordination des projets, EPADESA, Sophie Lufkin, architecte, École polytechnique fédérale de Lausanne et Thierry Salomon ingénieur énergéticien, président de négaWatt.

Tour’s new Fournier footbridge

Elioth is member of the consortium led by GTM Normandie Centre and Vinci Construction who won the competition launched in 2013 to replace the Fournier footbridge which spans the railway tracks in Tours.

The winning consortium has for mission to dismantle the old footbridge and then the design and build of the new one.

The two spans of the new bridge, two 60-span bow-strings with a central bearing, sweeps over a bundle of railway tracks serving Tours’ central station. The new footbridge will be built about 20 metres from its initial location, it will have two access ramps for PRMs: one straight, the other spiral.

Elioth will be in charge of the structural engineering services: steel frame and main structural works. The structural solution to be thought out shall strive for  lightness of the structure which is one of the challenges of the construction approach: the spans built at ground level parallel to the railway tracks then lifted by crane and placed on the piles: this operation to be carried out at night for each span. Only the central pile of the structure will be built within the SNCF boundaries.

Winning Consortium :

-   GTM Normandie Centre – VINCI Construction Group (leading agent for the consortium)
-   VIRY – FAYAT Group
-  ADS-STPL- IMHOTEP Group
-   ELIOTH –EGIS Group
-   B+M Architecture (Grégoire Bignier & Sébastien Mémet, architects).

Dividing the regions in accordance with energy ?

Whilst Manuel Valls announced on the 8th April a project to divide the Hexagon into 12 regions, Elioth was pursuing its research project within the frame of the Ignis Mutat Res program with the study of energy reparcelling in France (Reforme team, get more information here). Thus the team devised an algorithm by which it was possible to propose a variety of scenarios for boundary changing in France.

Issue: propose a territorial equality by comparing the densities of energy demand with the capabilities of the territory in terms of production of renewable energies. The animated images show some of the first results. More will follow beginning of May!

Here is what  a France divided into 12 regions could look like :

 

 

The Majunga Tower : natural ventilation of a hi-rise

The Majunga Tower is slowly revealing itself in Le Moniteur magazine!

”Majunga” has the distinguishing feature of being a high-rise building operating on natural ventilation.

Photographs in this article show the openings thanks to which this type of ventilation is made possible.

Elioth had the pleasure of working on the environmental concept of the tower, developing all the environmental studies (including air flow simulations) and which are in the process of being finalized for the construction phase BREEAM certification (BREEAM Award International 2012).
