"Application Standard of Building Information Model Technology in Guizhou Province", a local standard for engineering construction in the People's Republic of China, was officially issued by the Department of Housing and Urban-Rural Development of Guizhou Province. This standard is numbered DBJ52/T101-2020 and will be implemented from March 1, 2021. I participated in the compilation as the second main author. This standard is prepared on the basis of: 1) the requirements of "Notice on the issuance of the 2013 Plan for the Formulation and Revision of Engineering Construction Standards and Specifications" (Jian Biao [2013] No.6); 2) the extensive investigation and research as well as the earnest summary of practical experience by the standard preparation group; 3) the reference of relevant international and national standards; 4) the extensive solicitation of opinions. This standard consists of 12 chapters and 6 appendixes and explanations, and the main contents include: general provisions, terms, basic regulations, application environment, application organization and management, model creation and management, BIM application in feasibility study and planning stage, BIM application in survey and design stage, BIM application in construction stage, BIM application in operation and maintenance stage, BIM application in engineering cost, BIM based big data application, and appendixes and explanations, etc.

At the invitation of the editorial board of the journal, I am honored to be a member of the academic editorial board of Advances in Civil Engineering. This is my third part-time job for the editorial board after the Journal of Graphics and the Automation in Construction. I deeply feel the great responsibility and realize the broad development prospect of information technology in civil engineering. I will take this as the driving force to overcome the difficulties and strive to move forward in this field and direction!

Note: Advances in Civil Engineering, short as ACE, is an important academic journal in the field of information technologies in civil and building engineering. Its impact factor in 2019 is 1.176, and it is listed in the Q3 SCI journals.

“Understanding On-Site Inspection of Construction Projects Based on Keyword Extraction and Topic Modeling” has been published in IEEE Access.

On-site inspection of construction projects involves intensive paperwork, while generating large amounts of textual data. Lack of understanding of information hidden in text-based inspection records always leads to overlooking of important issues and deferred decisions. Therefore, a novel text mining approach based on keyword extraction and topic modeling is introduced to identify key concerns and their dynamics of on-site issues for better decision-making process. Through real project testing, it is proved that the proposed method could successfully extract key concerns hidden in texts and identify their changes with time, thereby enabling a more efficient on-site inspection and data-centric decision-making process. This research contributes to the body of knowledge a new framework for discovering key concerns and their changes with time in texts, and to the state of practice by providing insights on hot topics and their changes with time to reduce on-site issues and make decisions efficiently, which has certain reference significance.

I participated in the sixth National BIM Academic Conference as the host in Taiyuan, Shanxi. The conference focused on the application of "GIS+BIM" technology in highway engineering, and it attracted more than 500 university teachers and students, enterprise leaders and technical leaders from all over the country. At the meeting, my student Liu Yi made a paper report entitled "Research on the Application of Knowledge Graph in BIM Model Review", which mainly proposed a method of using knowledge graph to assist manual review of BIM models. In this paper, the deep learning model is used to extract entities and relationships from text data in mechanical and electrical field, and a small knowledge graph is constructed. When a BIM model is reviewed, the attributes of equipment can be shown by searching the knowledge map, and the relevant constraint statements in the specification can be obtained automatically. This method can save the reviewers the time of browsing and searching the specification, and effectively assist manual review of BIM model.
