Infrastructure development is massively done, but the current implementation of construction safety audit is not yet effective to prevent accident. Generally, the audit is limited to construction phase. Audit is rarely done in design phase, and if done, the audit result has never been used as reference for future audits. This research aims to formulate A Conceptual Framework for Knowledge Management of Integrated Design and Construction Phase Audit Process on Infrastructure Project Based on Risk, Using WBS, BIM and Web to Enhance Construction Safety Performance. The methodology was developed using literature study and deductive alaysis which then performed expert validation to ensure the concept developed. And the results of this study indicate that enhancing the construction safety performance in Indonesian construction industry, as an effort to prevent construction accident and mitigate infrastructure catastrophe, it is necessary to optimize the construction safety audit process by the development of knowledge management.
