Comparison of Learning Outcomes in Building Structure Models Using Construction Drawings and Building Information Modeling (BIM)

Abstract

The objective of this research is to study and compare the learning outcomes in building a single-story structure model using two-dimensional (2D) construction drawings and Building Information Modeling (BIM). The study divided students into two groups: Group A, which used 2D construction drawings to build the model, and Group B, which used BIM. The efficiency of time usage, accuracy, and understanding of structural elements before and after model construction were measured. The results showed that Group B took less time to construct the model in every component compared to Group A. The standard deviation (SD) of Group B was lower than that of Group A, indicating greater consistency and efficiency. Additionally, Group B demonstrated significantly better performance in constructing foundation, column, and beam components than Group A (p-value < 0.05). In terms of accuracy, the average scores of Group B were higher than those of Group A in the foundation and roof components. Although the t-test results did not show significant statistical differences (p-value > 0.05), Group B had a lower SD than Group A in every component, indicating greater consistency and accuracy.Furthermore, the research indicated that Group B had better understanding scores of structural elements than Group A both before and after the model construction. Group B's average scores increased more than Group A's after the model construction, consistent with previous studies that noted BIM enhances understanding of structural elements. The study concludes that the use of BIM technology not only improves the efficiency of model construction but also saves time and enhances students' understanding of building structures more effectively than traditional 2D construction methods. Thus, integrating BIM into the curriculum is an effective approach to developing skills and knowledge in civil engineering students.
