Abstract
The implementation of development projects in West Papua Province often experiences time extensions due to various factors, including technical issues, human resources, socio-cultural aspects, and material logistics. Additionally, construction projects in this region frequently face challenges due to the significant distance from major logistics centers. Therefore, it is necessary to analyze the influencing factors and control strategies. This study employs the Delphi method, involving construction experts in West Papua, including respondents from academia, construction specialists from service providers, and public works officials representing service users. The study distributes questionnaires to respondents to collect expert opinions, which are then processed to reach an agreement or consensus on each expert's opinion. The factors influencing project costs have scores ranging from 4.3 to 4.6, indicating that respondents strongly agree that these aspects contribute to project expenses. In terms of scheduling, the scores range from 3.9 to 4.7, showing that respondents also consider this a significant factor in project delays. Regarding quality, the average scores range from 4.2 to 4.6, demonstrating that this factor is perceived as highly influential on project quality. Based on the analysis results, the factors affecting cost control include ineffective cost supervision, price fluctuations, and execution method errors. The factors influencing time control are scope changes, financial issues, lack of supervision, and insufficient project coordination. The factor affecting quality control is the lack of on-site supervision. Strategies that can be implemented for cost, schedule, and quality control include utilizing project management software such as BIM and Microsoft Project, conducting material quality testing, implementing quality management systems, and conducting regular monitoring of project progress.
