The Ahmadou Ahidjo stadium in Yaoundé is unique for its presidential grandstands located on the east side. This specificity is also a drawback as it generate glare for public on this grandstand during the football games occurring in the afternoon or the early evening.
To reduce the inconvenience a membrane sun blocker was added on the top of the existing roof. However this sun blocker reduced as much the sun glaring as the visibility on the field.
As part of the refurbishment project of the stadium the Ministry of sport has required Egis to find and design a solution to solve this issue.
To solve this glaring issue Elioth propose a new lightweight roof above the existing presidential grandstand. The surface of the new roof was designed to maximize the shadowed area. This textile membrane roof was supported by and steel structure designed by Elioth and consisting of six claw shaped tridimensional truss beams partly supported by masts.
The result is a thin and elegant structure fully complying with the expectations of the Ministry of sports: improved quality of the presidential area, increase of the number of VIP seat protected from the sun and the rain and the creation of a new regie located within the roof and therefore directly above the field.
Another key feature of this project was its extremely tight schedule resulting from the need of the Ministry of Sports. From the very first sketch of the roof to its completion only fourteen months elapsed. Elioth was able to meet the this timeframe thank to the ranges of competences of its engineering team capable of addressing all aspects of the design (sun path evolution, structural and architectural design, textile membrane definition,..etc) without any outside external consultant.
