Aubervilliers footbridge

A new footbridge now crosses the “periphérique” at the Porte d’Aubervilliers in Paris! On the night of May 14 to 15, 2015, The infamous Parisien ringroad ground to a halt for a few hours while a 700 ton crane was positioned to complete the installation of the central span of the ZAC Claude Bernard bridge. At midnight, this 80metre long, 100 ton section was delicately raised into the air. A nail-biting 20 minutes later and the structure was in place. A dedicated site team took over and worked through the night to complete the assembly to the abutments.

Success! At daybreak, the cranes were folded and footbridge had found his place.

A little patience will be required however before you can tread its planks…

Brussels’ Parkway

Elioth is part of the winning team for the design and support of the urban project “Parkway Brussels” launched by the Territorial Development Agency for the Brussels-Capital Region. The team is led by TVK (attorneys architects) with Karbon, OLM, EGIS déplacements et mobilité and IDEA


The Elioth book is out !

Out now! Elioth, 10 years after:  looking back on ten years of practice. Check it out here. Happy reading!

Housing of the 3rd Millennium

Clip’n Clim, the active façade concept “plug & play” developed by Elioth for building renovation programs was one of the seven projects selected after the call for ideas launched by Habitat Toulouse for the “Housing of the 3rd Millenium”.

The ceremony announcing the results was held on Thursday 4th December in presence of 240 professionals in housing and construction. The evening was presided over by Franck Biasotto, Chairman of Habitat Toulouse, and deputy mayor responsible for housing, and also José Cohen-Aknine, General Manager of Habitat Toulouse.

The 7 winners will have the great privilege of witnessing their project implemented by Habitat Toulouse within a time period of two  years.

You can watch the video presenting the project here. Contact

Data Design by Elioth !, a website developed by Elioth for the City of Paris, is now live!

The challenge of this visualization was to popularize the concept of urban metabolism, or how energy, material and water flows are set in motion to support a territory’s activity.

This tool shows concrete and local optimization solutions of this flow circulation, as proposed by the much talked about circular economy. How could we reuse materials from demolitions instead of importing new ones? How could waste be turned into energy or reusable materials?

YouTube Preview Image

Built for the call for projects “Urban Metabolism Optimization” initiated by the City of Paris, the website presents multiple examples of effective and already operating solutions, as well as the laureate projects.

It also provides access to contextual visualizations and comments from city to regional levels (Paris, Great Paris and Ile-de-France), trends…

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.

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
