摘要：This paper has two main sections, the first of which provides a summarized review of the literature focusing on existing studies of the adversarial relationships between main and sub-contractors in project execution phases. Such relationships become hurdles for the construction organizations to achieve quality relationships. Organizational culture influences these relationships due to its constituent elements of value, leadership style, procedures, and routine, as well as defining success or failure. Drawing from the first section, the second section presents the details of the research project being undertaken. Suitable research methods have been developed to meet the research objectives eliciting based on fundamental questions. Primary data collection will use a mixed methods approach, i.e., questionnaire surveys and semi-structured interviews to obtain respondents opinions related to social interactions in Indonesian infrastructure projects. The project-based organizational culture assessment of Zou (2014) and relationship quality evaluation of Jiang (2016) are utilized in this study. Statistical software will be used to analyze most data expected to be obtained in the future and then the results will be discussed to develop a framework to improve relationship quality in achieving project performance.
