Abstract

Understanding how BIM is being used in a real construction is the most important in order to facilitate the practical uses of BIM in construction projects, which can lead to improvement of site work efficiency. Primarily BIM works in construction phase were classified into eleven sub-tasks, and quantitative analysis were conducted with BIM data files and BIM daily work reports from a building project that the researcher was personally involved. The analysis revealed that the total number of tasks using BIM in the project was 244 cases and actual work hours were about 3,260. From a detailed analysis with seven sub-tasks only corresponding to the group of 'direct support' task, it was also found that tasks related to 'design change' were the most with 53.8 percent and 'constructability review' with 17.6 percent and 'Shop drawing' with 15.5 percent were followed. On the other hand, tasks associated with 'modification of modeling' were few with 0.8 percent. Furthermore, an unnecessary BIM works caused by 'avoidable design change', namely 'design error', 'omission of drawing', and 'rework', was approximately 14 percent. The quantitative analyses results found from this study will serve a good foundation for facilitating the uses of BIM in building construction project and eventually improving on-site work efficiency.
