Burkina Faso is making steady progress on the construction of the new Ouagadougou-Donsin International Airport, a strategic infrastructure project designed not only to enhance the country’s air connectivity but also to strengthen its defense capabilities. Located approximately 35 kilometers northeast of the capital, the airport will cover an area of 4,400 hectares and will feature a passenger terminal, a presidential pavilion, logistics areas, a museum, and, notably, a military base. With a projected capacity of one million passengers per year, completion is expected by 2025, with 92% of the works already finalized. The project is being managed through a 30-year concession with the involvement of European investors, underlining its significance both nationally and internationally.

The roofing was executed using a single-sheet, self-supporting curved roof system — a technical solution known for its efficiency and functionality in large-scale projects. In this case, the curved INCO 70.4 profile was used, which is capable of spanning up to 8.10 meters without intermediate supports, allowing for optimal architectural design and maximizing the interior space’s usability.

Key advantages of this system include its remarkably fast installation — significantly reducing on-site construction time — and its excellent mechanical performance, offering strong structural resistance to overload. Furthermore, as the vaulted roof is formed from a single continuous piece, there is no need for overlaps or joints, ensuring complete waterproofing against rain and other weather conditions. This improves both the durability and energy performance of the building. This type of roofing solution is particularly well-suited for industrial buildings, logistics facilities, or spaces that require efficient, long-lasting, and quickly installed coverage.
