Causality Model in Developing Building Information Modeling-based Audit Using Knowledge Management System for Construction Safety Performance Improvement

The construction sector in various developing countries shows a positive trend, including the construction sector in Indonesia. One of them is the increase in infrastructure for high housing needs from year to year, but the availability of land is increasingly limited, so high-rise buildings are a solution. Unfortunately, data shows that high-rise building projects are still workplaces that contain the highest risk of accident fatality. On the other hand, the construction sector’s need for building information modeling technology has increasingly been proven to increase the effectiveness of monitoring and evaluating construction project implementation. So, research is needed to find the causality relationship between essential factors in developing a construction safety audit system, building information modeling, and knowledge management approach to improve construction safety performance. The research method is a literature study questionnaire survey and expert validation. Data were processed using structural equation modelling analysis to describe the causality relationship between essential factors in developing construction safety audit systems. The results concluded that the causality relationship of building information modeling utilization factors, information systems, construction safety audit process and knowledge management system significantly influenced the improvement of construction safety performance with an R-Square value of 75.9%.
