This paper introduces the structural design of the EPC project of a cement plant in Africa. Through studying the contract, it clarified the requirements for the structural design part and determined the design principles. It did a good job in design subcontracting management, formulated a drawing approval plan, and improved the review efficiency of project drawings. Combined with the previous design work experience and the adoption of the limit design method, the design and construction costs are reduced on the basis of ensuring the safety of the structure.
