    Our new journal article entitled "Geometric optimization of building information models in MEP projects: Algorithms and techniques for improving storage, transmission and display" has been published online in "Automation in Construction". This study was one of the achievements of BIM-based application on construction and Operation & Maintenance for MEP. MEP models are generally characterized by information redundancy and a high density of irregularly shaped components. Consequently, they require large storage spaces and are not conducive for interchange purposes. Volume of storage data was reduced by 40% to 50% through mesh simplification. Data transmission volume was reduced by more than 80% for components with complicated geometry without affecting the topology of the components. Finally, the displayed models were delivering very good quality for application of BIM-based systems.

    Our new article paper entitled "Development and Application of GIS-based Lightweight Operation and Maintenance Management Platform for Large Public Buildings" has been published in the Journal of Graphics. This study presents an application method of lightweight O&M management platform for large-scale public buildings based on GIS. This paper presents an approach to convert drawings of large-scale public buildings are converted into map services. Then attribute data are summarized to form hierarchical structures, and unique identifiers are given to establish standard attribute libraries. Based on these libraries, O&M management processes are reviewed to form standard O&M management procedures and data flows. A lightweight O&M management platform is developed, which realizes the information management of the terminal of Kunming Changshui international airport.

    The research team has published a paper entitled "A Review on 3D Spatial Data Analytics for Building Information Models" in "Archives of Computational Methods in Engineering", which is an international high-level journal in engineering technology industry. This study reviews state-of-the-art of related research and provides a summary of achievements and challenges in this area. Then, a framework consists of management, analysis, and application of 3D spatial data of BIM and a detailed discussion of each part are proposed, which would give the readers an overview of relevant methods, technologies, and tools. Moreover, potential research directions and open issues for future work are also discussed. The paper enables researchers to get a comprehensive understanding of 3D spatial data analytics of BIM as well as suggestions for future work, and thus makes a solid contribution in this area.
