    Research Prospect of BIM-Based Information Technologies for Engineering Management has been published in the journal Industrial Construction.

    Aiming at the development of information technologies for engineering management, this paper summarized BIM-related research from two aspects: the organization and processing of engineering data as well as the mining and analysis of such data. The research investigated involved the Industry Foundation Classes (IFC) standard, multi-scale information models, model lightweighting technology, and the key steps and typical methods of data mining in the engineering industry. On this basis, the bottleneck problems faced by BIM and information technologies for engineering were analyzed, and three main future development directions were then proposed and discussed: digital twins in the engineering industry, city information models, and knowledge graphs in the engineering industry. This paper is expected to provide a reference for further research and technology application.

    Note: The research results were funded by the National Key R&D Program of China and the National Natural Science Foundation of China.

    Maturity Assessment of Intelligent Construction Management is available online at Buildings.

    In the new era of Construction 4.0, the application of a large number of intelligent information technologies (ITs) and advanced managerial approaches have brought about the rapid development of intelligent construction management (ICM). However, it is still unclear how to assess the maturity of ICM. In this study, a maturity assessment system for ICM was formulated through literature reviews, questionnaires, expert discussions and a case study. A maturity scoring table containing five assessment dimensions and twenty assessment indicators was developed, and corresponding maturity levels and a radar chart of dimensions were designed. A case study of the assessments of two construction enterprises was conducted to validate that the proposed assessment system could be used by construction enterprises to quantitatively assess their ICM maturities and obtain both overall and specific assessment results. This study also proposed practical improvement methods to improve ICM maturities for construction enterprises with different maturity levels. Furthermore, the study also discussed the development direction of ICM at present and in the short-term future, which should be paid more attention to by the construction industry.

    Note: Buildings, a journal in the field of engineering technology, belongs to the SCI journal in Q2, with an impact factor of 3.324 in 2022. The first author of this paper is Chao Lin, a master’s student in our research group. The corresponding author is assistant professor Jia-Rui Lin in the Department of Civil Engineering of Tsinghua University.

    Congratulations to Yuan Shuang, a PhD student from the Department of Civil Engineering of Tsinghua University, and Zhang Yunyi, a postdoc, who successfully passed the dissertation defense.

    Among them, the title of Yuan Shuang's paper is "Collaborative Research on Building, Personnel and Digital Model in Energy Consumption Management", which analyzes and summarizes the collaborative relationship and architecture of building entities, personnel and digital model in the energy consumption management of building operation and maintenance period. Behavior for energy consumption, personnel, environment and operation data such as the design of the standardized data model and data integration method based on BIM, staff behavior detection algorithm is proposed based on ensemble learning, building the human-computer interaction method based on metope touch with collaborative data cleaning methods, and develop the corresponding energy consumption management platform based on the actual engineering data for the inspection method.

    Zhang Yunyi paper titled "construction intelligent Internet of key technology and development", the study put forward the construction engineering technology architecture of Internet of things platform, designs the general structure of iot gateway and three kinds of realization forms, and puts forward the data standardization expression and storage mode, realized the iot data with BIM data fusion and unified management, according to the specific needs of the business, The technical schemes of alarm and equipment linkage, process automation identification, object recognition and positioning and other business scenarios are designed and realized. Combined with the actual engineering project, the proposed method, technology and platform are verified by application.

    I was invited to attend the 52nd BIM special technical report of Guangzhou Metro Lecture Hall, and gave a lecture titled "From Data to Knowledge -- Innovation and Development of Engineering Management Information Technology". About 240 leaders and senior management of the group attended the meeting.

    At the meeting, the definition, processing and optimization of the information model were introduced, and then the acquisition, expression, storage, management, data mining and application methods of the construction of the adjacent city engineering data were discussed. On this basis, the development of project management information technology is prospected, the development trend, research direction and application cases of the combination of ClM, digital twin and knowledge graph with BIM technology are introduced, and the development approaches of modernization and intelligence of project management are explored.

    BIM technology has gradually turned into one of the necessary skills of civil engineering practitioners. However, we still need to continue to dig the application prospect of BIM technology, and drive the sustainable development of social economy in a safer and better way in the post-BIM technology era!

    The summer is long and green. In this summer, in order to enhance the sense of team cooperation, enhance the cohesion of the team, and also to see the beautiful scenery of pengcheng beach in summer, the members of the research group went to Dapeng New Area to carry out a team building activity.

    The event took various forms, including sports competitions, puzzle games and networking dinners. In the process of sports competition, we are divided into two teams, red and blue, compete and go, sweat down the game, happy and matchless, to show a positive, persistent spirit. The puzzle game fully reflects the team members quick thinking, articulate, good at observing the characteristics of people, but also full of laughter. In the exchange dinner that followed, we did everything by ourselves, from making fire with charcoal to washing food to baking and tasting, all permeating the joy of working. Among them, both the reluctance to bake mistakes, but also the amazing performance of the praise, pushed everyone's enthusiasm to the peak!

    The sun is warm, live up to the time, with a team construction to a date in July, our research group will continue to move forward with this wonderful!
