Active Learning Method

To enhance the engagement of Civil Engineering students and encourage active learning, a virtual construction site investigation game is developed in the present paper. 3D construction site environment is built based on BIM models and relevant objects common on construction sites are created to enhance the realistic. Navigation and Interactions are developed to enable the students to explore the virtual sites freely and get instant feedbacks. Different modules, such as Questions and Tasks, are developed to exam how well the students master the domain-related knowledge. Unity, a cross-platform game engine, is used as the development platform for this research project. The architecture, mechanism and the implementation are described in detail in this paper. A pedagogical methodology for improving the quality of learning is thus developed by transforming traditional instructional delivery techniques into technology-based active learning. Students’ engagement in the learning process is improved by establishing a contextual connection between ordinary textbook materials and technologies that students use in their daily routines. This new approach enables students to interact, and learn abstract topics in engineering design and construction method. The effectiveness of this active learning method is investigated by the feedback from two groups of students using a questionnaire. The potential benefits of the proposed research are: enhanced understanding of complicated structures; better accessibility to more construction site virtually; more convenient and flexible time for learning practices; and safer site visit with this pre-training tool.

Virtual Construction

PurposeConstruction safety has been a long-term problem in the development of the construction industry. An increasing number of smart construction sites have been designed using different techniques to reduce injuries caused by construction accidents and achieve proactive risk control. However, comprehensive smart construction site safety management solutions and applications have yet to be developed. Thus, this study proposes a smart construction site framework for safety management.Design/methodology/approachA safety management system based on a cyber-physical system is proposed. The system establishes risk data synchronization mapping between the virtual construction and physical construction sites through scene reconstruction design, data awareness, data communication and data processing modules. Personnel, mechanical and other risks on site will be warned and controlled.FindingsThe results of the case study have proved the management benefits of the system. On-site workers gradually realized that they should enter the construction site based on the standard process. And the number of people close to the construction hazard areas decreased.Research limitations/implicationsThere are some limitations in the technology of smart construction site. The modeling speed can be faster, the data collection can be timelier, and the identification of unsafe behavior can be integrated into the system. Construction quality and efficiency issues in a virtual construction site will also be solved in further research.Practical implicationsIn this paper, this system is actually applied in the mega project management process. More practical projects can use the management ideas and method of this paper to ensure on-site safety.Originality/valueThis study is among the first attempts to build a complete smart construction site based on CPS and apply it in practice. Personnel, mechanical, components, environment information will be displayed on the virtual construction site. It will greatly promote the development of the intellectualized construction industry in the future.

Abstract Learning

Abstract: Learning from experience approach has been widely adopted in the academic cluster of Built Environment including Civil Engineering field. To further strengthen this aspect, a study in exploring construction site visit as an aid to educational component in teaching and learning method is significant. This provide a platform which helps civil engineering students to enhance their safety knowledge and understanding by experiencing the real time situation at the construction site. The objectives of this study are to: (1) determine the effectiveness of site visit approach in teaching and learning of construction site safety (2) measure the performance between students who acquire knowledge related to safety by experiencing one site visit compared to students with zero site visit; and (3) compare the achievement and understanding between male and female students if site visit is adopted in the teaching and learning process. A set of questions is designed as an instrument and participating students are required to answer the questions nonverbally to show their knowledge on the construction site safety. Based on the scoring marks, a statistical analysis has been conducted. The result indicates that students with one site visit have better achievement and understanding compared to students with zero site visit. In addition, the result also shows that with one site visit, female students have better performance in the score marks compared to male students.   Keywords: construction site, experience-based learning, site safety, site visit

Pipeline Crossing

Directional drilling technology is an important and very promising trenchless pipeline crossing technology. On the basis of the related literature research at home and abroad and our pipeline construction site investigation, focuses on several common soil properties are introduced, and then the formation adaptability of directional drilling is analyzed. The drilling selection methods are made when drilling in the specific geological conditions, and the possible risks of the construction process have been classified in the directional drilling.
