Abstract

Upstream oil and gas construction projects in South Sumatra face significant challenges related to execution delays due to geographic, technical, and social complexities. This study aims to analyze the factors causing Project Delays and formulate context-specific mitigation strategies. The method employed is Partial Least Squares - Structural Equation Modeling (PLS-SEM), involving 186 respondents consisting of project owners and industry practitioners. The results indicate that the Material variable has the most significant direct impact on Project Delays, followed by the Planning and Design variable. The Contractor factor acts as a mediator for the influence of the Labor, Financial and Economic, and External variables. Dominant delay-causing indicators include material shortages, inadequate site investigation, design mismatches, inaccurate price negotiations, and low safety awareness. The results of the Focus Group Discussion (FGD) support the quantitative findings by highlighting the importance of field data-based design validation, comprehensive site investigations, and the enhancement of local contractor capacity. The Focus Group Discussion also revealed that material unpreparedness and social conflicts arising from limited legal awareness and moral responsibility within local communities have further contributed to project delays. Based on these findings, the recommended strategies include conducting comprehensive site investigations based on subsurface, geotechnical, and social data, involving contractors from the early stages, implementing projects through digital approaches, and managing social risks through Corporate Social Responsibility (CSR) strategies and stakeholder engagement. This study offers practical contributions to improving the efficiency of upstream oil and gas projects, particularly in high-complexity regions such as South Sumatra.

Abstract

Delays in electricity transmission projects within PLN UIP JBTB have become a dominant issue. The majority of projects during the 2020–2024 period experienced delays, as reflected by milestone deviations, cost overruns, and time overruns, which disrupted electricity supply reliability and adversely affected the company’s corporate image. This study aims to analyze the indicators that form latent variables influencing project delays using an explanatory qualitative approach with the PLS-SEM method. Primary data were collected through questionnaires from 140 respondents selected via purposive sampling, comprising project owners, technical experts, and consultants. The results indicate that the elimination of the indicator related to community resistance to the project suggests that project delays are not driven by overt social opposition, but rather by weak communication quality and insufficient community engagement. In the licensing factor, all indicators demonstrate that project delays result from the cumulative effects of slow processing, administrative unpreparedness, and weak inter-agency coordination. Regarding the financial factor, project delays are more strongly influenced by the project financial system’s ability to maintain cash flow continuity and cost control than by perceptions of the financial impact of delayed payments. The human resources factor confirms that project delays are associated with an imbalance between workload and workforce capacity, competence, productivity, and motivation. Meanwhile, the logistics and supply chain factor indicates that unprepared procurement and material distribution systems are a significant source of project delays, even when construction activities are technically well planned.

Abstract

The rapid growth of commercial building development in Bali Province has led to increased construction activities and a higher potential for construction waste generation, while the implementation of construction waste management during the project execution phase remains insufficiently integrated. Although various construction waste management performance indicators have been proposed in previous studies, empirical validation of the underlying factors and indicators using structural equation modeling (SEM), particularly in the context of commercial building projects, remains limited. This study aims to identify and validate the key indicators determining construction waste management performance in commercial building projects in Bali Province. Data were collected through a questionnaire survey and analyzed using partial least squares structural equation modeling. The results confirm 21 valid indicators representing four key performance-determining variables. The findings indicate that construction methods, policies and governance, design and documentation, as well as material and equipment management have a significant influence on construction waste management performance. Among these variables, reducing unnecessary activities (outer loading = 0.817), supervision of construction activities (0.860), design errors (0.851), and warehouse capacity (0.841) were identified as the most representative indicators for their respective constructs, as reflected by the highest outer loading values. This study provides empirical contributions to the development of construction waste management performance indicators and offers practical implications for improving waste management performance in commercial building projects.
