ABSTRACT International Construction Joint Ventures (ICJVs) offer benefits to both local and foreign partners. However, their failure rates tend to be high, leading to poor ICJV performance. Effective Project Management (PM) is considered a means to resolve challenges in a construction project. Therefore, this research aims to address the challenges in ICJV projects within the Sri Lankan construction industry through PM practices to establish successful ICJVs. The research adopted a mixed-method approach. A preliminary survey was conducted to validate the challenges in the Sri Lankan context. After that, challenges were ranked based on their significance level using the Relative Importance Index (RII) method through a questionnaire survey. Then, Semi-structured interviews were conducted to identify the PM practices that can address significant challenges through code-based content analysis. The study revealed 38 challenges applicable to ICJVs and identified 88 PM practices for resolving 10 significant challenges out of the 38 identified in ICJV projects in Sri Lanka (SL). Finally, a framework was developed for successful ICJVs by addressing challenges through PM practices. This study marks the first attempt to establish a framework for successful ICJVs by addressing challenges through PM practices in the Sri Lankan construction industry.
