Effective project time management (ETM) is a critical success factor for projects. Therefore, an effective time management for the construction project is important in managing risk of the delayed completion project. To date, much of the literature has focused on the project time management analysis was very limited to the direct and indirect relationships between project time management process (TMP) and project performance (PP). Therefore, the aim of this study is to fill these research gaps by empirically examining the relationship between ETM and PP. The objectives of this study are to assess the project time management practice implemented in Rama Construction PLC and explore the effect of Project Time Management on project performance. Moreover, the study considered stakeholder participation, effective communication, project time management process, risk mitigation, and procurement method to measure the project time management practice. To achieve these objectives, there were ninety six questionnaire sets distributed to the respondents. Both quantitative and qualitative survey tools were used to collect the data from respondents. Out of the total respondents 84 responses were obtained, accounting to 87.5 % response rate. The quantitative data analysis was conducted using structural equation modelling, and the qualitative data was analyzed using conceptual qualitative content analysis. The findings suggest that project time management affect the ability to achieve both sets of quantitative PP (i.e., project time, and project cost) and qualitative PP (i.e., project quality, and stakeholder satisfaction) positively. These findings suggest that implementing effective project time management increase the ability to achieve the desired project performance and that effective project time management is in fact advantageous to construction projects. So high value should be given to project time management in the construction industryen-USThesis
