Context and challenges

The client, which is a leading aviation group, wanted to invest in an industrial system for the manufacture and assembly of aeroplanes in India.
To meet environmental challenges, the building must have low energy consumption thanks to complete sun protection and extensive use of natural lighting.
Another special feature of the project is that flooding risks must be accounted for, due to the country's climate.
One of the major challenges is the construction of an arched roof spanning 75 m to make the building fully modular. This arched roof has a metallic framework covered with a filtering skin.

The client called on Assystem to design and oversee construction of the building.
