Comment

Project Source: National Natural Science Foundation of China
Role: Person in charge
Abstract: Aiming at the problems such as the massive information management and integrated application in current safety management of large public buildings during operation and maintenance period, this project combines the safety management system of large public buildings to construct a BIM&GIS-based multi-scale model for operation and maintenance management. The proposed model is based on the international construction industry standard IFC, and via introducing the emerging frontier information technology like BIM, internet of things, cloud computing, etc. Then, by means of integration innovation, the operation and maintenance information management technology including dynamic monitoring, evaluation and early warning technology for safety performance will be researched. A BIM-based Safety Management Platform (BIM-SMP) for large public buildings during operation and maintenance period will also be developed. This project is expected to provide a complete set of theory, method, technology and platform support for the creation and application of the safety information model for large public buildings during operation and maintenance period. It realizes the combinations of macro management and micro management, information management and information applications, dynamic monitoring and real-time evaluation, and post-disaster simulation and escape guidelines for the safety management in operation and maintenance period. Therefore the safety problems of construction can be discovered in time and the post-disaster emergency plan can be made as soon as possible. Furthermore, the safety performances of the building structure and affiliated mechanical and electrical, plumbing (MEP) equipment are improved and the building disaster losses will be reduced.

4D simulation and analysis of safety performance of time-depended structure oriented to design and construction phase

Comment

Project Source: National Natural Science Foundation of China
Role: Person in charge
Abstract: There're two main methods for project safety management during construction, i.e., safety management and structural safety analysis. However, related researches mainly expanded from their own point of view, with no comprehensive analysis linking. In fact, factors leading to any kind of safety incidents in the construction are not isolated. To achieve integrated time-dependent structural safety analysis and management during construction, it is an essential and feasible way. to adopt information technology. This study introduced advanced databases, artificial intelligence and other emerging computer information technology, combined with time-dependent structural analysis method in the field of traditional structural engineering, created a unified information model oriented to both design and construction phase for storing and managing huge amounts of construction information, and implementing the unity of structural analysis model in various finite element analysis software. Then the 4D technology is applied to simulate and describe the whole construction process. Different FEM software are used for dynamic finite element structural calculations to achieve dynamic simulation and analysis of structural safety performance within the whole construction process. The research may provide not only references to consider force changes during construction in the design phase, but also new safety analytical tools for the construction site. It achieves the goal of improving the efficiency and quality in design and construction phase, reducing life cycle costs, reducing construction process safety incidents.

BIM- and 4D- based dynamic collision detection for time-depended structure and movable facilities at construction site

Comment

Project Source: China Postdoctoral Science Special Foundation
Role: Person in charge
Abstract: By combining 4D and BIM, progress information and spatial information of space entity were tightly integrated to comprise a 4D space information model of structures and facilities, which is no longer limited to a 3 dimensional performance changing over time. Based on this 4D space information model and a proposed improved physical collision detection algorithm, the site collision conflict analysis capability was extended to every time point during construction, carrying out dynamic physic collision detection between the time-dependent structure and movable facilities at each time point. This research may strengthen the site management during construction to avoid safety incidents caused by the collisions between the time-dependent structures and movable site facilities. It may also provide new methods to solve the problems of subjective decisions relying on managers, and seems to have theoretical significance and application prospects.

Role: Participate
Abstract: According to the existing deficiencies and urgent requirements of applying current BIM technologies to the AEC/FM industry, this research proposes a BIM architecture framework for various stages and applications in building lifecycle, based on industry foundation classes (IFC) standard and cloud computing technology which is a newly-emerged IT technology worldwide. Then, a progressive and multi-participants oriented modeling method is established, followed by in-depth researches on some key technologies, such as distributed storage and management of BIM data, BIM data integration and fusion, sub-model extraction, BIM server and application mechanism based on process, etc. Finally, a cloud-computing-based BIM integration and server platform (BIMISP) will be developed. The purpose of this research is to present a set of theories, methods and technologies, and develop an integrated platform, to support BIM data sharing, lossless delivery and application among the whole building lifecycle including planning, design, construction, and operation and maintenance phases. The prospective findings will be useful for improving efficiency and quality of building activities, reducing resource consumption, and implementing sustainable development strategy during building lifecycle.
