This case shows the on-site acceptance inspection of our foldable container houses for an engineering project in Kenya. This project adopts two-storey row modular buildings with simple white facades, external corridors and staircases. Clean and neat, these units are used as worker dormitories and on-site offices. Each cabin has a modular foldable structure and is fully prefabricated in our factory. On-site hoisting and assembly are fast with limited civil works, making it ideal for rapid deployment at African construction sites. The wall panels are selected to suit the tropical savanna climate, delivering reliable heat insulation, rain resistance and anti-corrosion performance. They adapt well to large temperature swings between day and night as well as heavy rainfall in rainy seasons. When folded, the cabins occupy little space and are convenient for export by sea. Water and electrical pipelines are prefabricated inside, so the units are ready for service once assembled and connected. They are suitable for infrastructure dormitories, project offices and auxiliary camp buildings in Kenya. Multiple units can be stacked into multi-storey rows and linked together. The cabins can be disassembled, relocated and reused for new projects. Jinzhong provides customized rainproof and heat-insulation configurations tailored for African tropical climates. We offer one-stop mass production and on-site installation guidance. It is an excellent temporary building solution for large engineering camps across Africa.
