In construction projects, both in the public and private sectors, the occurrence of risks, such as Contract Change Orders (CCOs), is common, posing challenges to project implementation. CCOs, reflecting uncertainties in project execution, can manifest at any stage of the project, from inception to completion. Within the construction projects undertaken by the Central Lombok PUPR Office, serving as the project owner, organizer, or government project stakeholder, CCOs frequently occur, indicating a significant area of concern. This study aims to identify the primary causal factors and influences of CCOs through the utilization of questionnaire surveys, bolstered by statistical analysis employing SPSS for Windows. Our findings reveal that the predominant causal factor contributing to CCOs is the 'increasing volume according to field needs,' representing 6.61% of the total factors identified. Furthermore, the influence of CCOs on project performance is notably impacted by 'increasing daily production,' accounting for 17.4% of the total influence observed. This research not only sheds light on the specific factors driving CCOs but also underscores their implications for the successful execution of construction projects in Central Lombok Regency. By understanding these dynamics, stakeholders can implement proactive measures to mitigate risks, enhance project management practices, and ultimately improve project outcomes.
