Virtual reality (VR) technology is a kind of computer simulation system that can create and experience the virtual world. It uses computers to generate a simulation environment. It is a system simulation of multisource information fusion, interactive three‐dimensional dynamic view, and physical behavior for users to immerse in the environment. The practical application of virtual instructional models is developed to support civil engineering teaching, disciplines related to civil engineering processes, including classroom education and e‐learning technologies. The virtual model can be interactively operated, allowing the teacher or student to monitor the physical evolution of the work and the progress of architectural activities inherent in it. This paper analyzes the development status of VR and its application in teaching research and describes the application of a VR teaching model to demonstrate the feasibility and advantages of VR teaching. The developed application can display the physical evolution of the task, detect the planned construction sequence, and view the shape details of each construction component. The use of VR technology in developing these instructional applications contributes to education by increasing the efficiency of the models to allow for the interactivity of each simulation task. Therefore, the new concept of VR technology applied in teaching mode brings a new perspective to civil engineering education.

Lean construction and Building Information Modeling (BIM) are increasingly utilized in quantity surveying (QS) production, yet the dilemma of BIM and LEAN interaction is largely ignored. The main problems occurred in traditional quantity surveying services among public and private organizations are experiencing collisions, uncertainties, ambiguities and complexities, which are expected to be mitigated through the implementation of BIM-LEAN practice. However, due to the absence of enough knowledge and confidence to encounter BIM-LEAN for QS practices, quantity surveyors are hesitant to prosecute this new technology but default back to conventional inefficient working methods. Through a questionnaire survey, this paper is to identify the challenges and strategies in implementing BIM-LEAN in QS practices as well as to develop a conceptual system dynamics model to assist this effort. The challenges related to financial issues such as hardware and software cost and training cost could have more impact on small-and-medium-sized QS firms. Lack of BIM-LEAN experts in organizations could be another barrier to implementing BIM-LEAN in QS practice, and this, in turn, could further affect the decision-making process to adopt BIM-LEAN thus initiating a death spiral.

In order to accurately analyze the building energy consumption and identify the problem of building energy consumption in advance, this study carries out the energy consumption analysis based on BIM (Building Information Modeling). The research object is a four-story college student dormitory in Beijing, and this set of BIM-based energy consumption simulation data was obtained using standard operating procedures (SOP). This operating procedure can start energy consumption analysis in the conceptual design stage, and developers can participate in real-time through the use of a three-dimensional information model, without additional design required. Then, comparing this study with the traditional energy consumption analysis, we see that the SOP of this research result has the following advantages: SOP function analysis is more professional, and the visual display method is more popular and intuitive; due to the flexible file format of the SOP, when data exchange is required between different software, the SOP can realize more convenient operation, and users can identify problems in the early stage of design through the SOP, correcting the scheme according to the simulation results, which is conducive to the development of the construction process. Finally, this study puts forward the analysis and estimation of energy consumption in different stages of the building life cycle, so as to provide researchers with ideas for improvement .
