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 method that uses in the research is qualitative and quantitative analysis to formulate the development. And the result targeted 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 so construction safety audit can be optimized to improve construction safety as an effort to prevent construction accident and mitigate infrastructure calamity during accelerated development era in Indonesia.
