The Tanzania Sports Center, contracted by Sigma Group . It was completed in December 2017. The project size is 40,000 square meters, using PTFE and PVDF membrane materials, and the project construction period takes 140 days.

The upper part of the auditorium is entirely covered by a membrane structure, and the plane shape is oval. The entire stand is covered easily, which simplifies the building structure and at the same time the weight of the building is much easier, making the construction easier, reducing the risk factor of the construction workers, and shortening the construction period of the project.

The interaction between these umbrella-shaped membrane structural units forms a complete spatial structure system that can resist external loads.
