Taking the Heart of the Rainforest project in Haikou City as the research object, for the project steel structure is interlaced and complex, high precision installation requirements, tight schedule and other characteristics, from the engineering structure characteristics, processing and manufacturing, and construction methods and other aspects of the analysis: quality control measures and principles of complex space structure size, welding and assembly are proposed. At the same time, BIM technology was used to fully disassemble the structure, make a reasonable structural division, and propose a reasonable construction sequence as well as installation accuracy assurance measures, which provided a solid foundation solution for the smooth implementation of the subsequent project. The relevant results can provide technical reference for the processing and manufacturing as well as construction application of similar complex space steel structures in the future.
Keywords: complex space steel structure; BIM technology; simulation; construction key technology.
