Infrastructure development is being carried out massively, but this is accompanied by an increasing number of accidents in the construction industry. This places the construction industry among the most accident-prone sectors compared to others. This trend highlights the ineffectiveness of current construction safety audits in preventing accidents, as these audits are generally concentrated in the construction phase. Audits during the design phase are still very rare, even though everything conducted during the design phase will have a higher effect on the occurrence of accidents than during the construction phase. The limited number of auditors is one of the problems. So, an audit system is needed to make the audit process easier, faster, and more cost-effective. This research aims to develop a risk-based safety audit system for high-rise buildings under the Design-Build (DB) method. The research method was used qualitatively in formulating the development of an integrated audit system. The experimental process was conducted in two phases: (1) formulating a knowledge base for construction safety audit criteria and (2) developing a web-based information system. As a result, the expert assessed that the development of a web-based information system helps the construction safety audit process to be easier, faster, and cost-effective, makes it easier to obtain safety performance data, and facilitates the evaluation of evidence related to construction safety audits so that the audit results can be used for continuous improvement in order to enhance construction safety performance. © 2025 Seventh Sense Research Group®
