Abstract

The construction of toll roads requires supervision consultants capable of ensuring project quality, time, and cost performance, yet a structured and measurable assessment framework is lacking. This study develops a comprehensive performance assessment rubric for toll road supervision consultants using quantitative methods, including a literature review, a survey of 50 respondents, validation by six experts, and an application test by 12 evaluators. Data were analyzed using validity and reliability tests, Mann–Whitney U, AHP, TOPSIS, and ROC methods. The results identified 18 valid and reliable indicators grouped into three dimensions soft skills, technical skills, and project supervision. The most critical indicators were QA/QC (C=0.810), periodic reporting (0.782), and work volume management (0.711). Final dimension weights were 40% for technical skills, 30% for soft skills, and 30% for project supervision. Application of the rubric indicated consultants’ performance remained in the “Average” category, highlighting areas for measurable improvement in supervision practice.

Abstract

The maintenance of cultural heritage buildings is gradually shifting from a curative approach toward preventive conservation supported by digital technologies. Although Heritage Building Information Modeling (HBIM) has been widely adopted, the resulting models are generally static and incapable of integrating real-time structural monitoring data. This study employs a qualitative case study approach combined with a literature review. The literature review was conducted to identify variables, subvariables, and indicators, which were subsequently validated by experts. In addition, benchmarking of previous frameworks was carried out to understand existing structures and methodologies. Based on these findings, a framework was developed according to the research requirements and further validated by experts to ensure its reliability and practical applicability. This study proposes a Digital Twin (DT) framework for cultural heritage buildings by integrating geometric building models, historical information, and dynamic data obtained from accelerometer sensors. The framework consists of four main layers: the information source layer, the BIM model layer, the integration layer, and the application layer for visualization and decision-making support. The framework was implemented in the Jakarta Cathedral to evaluate the integration of sensor data into the HBIM environment. Expert validation results indicate that the proposed framework provides a systematic approach to supporting preventive conservation for cultural heritage buildings with complex geometries.

Abstract

Public school building construction projects in DKI Jakarta Province are one of the government’s strategic programs to improve the quality of educational facilities. In their implementation, the construction procurement process plays an important role in determining project success, particularly in terms of timely completion. However, various activities within the procurement process have the potential to create delay risks that may affect overall project performance. This study aims to identify activities in the construction procurement process that have the potential to cause delays and to assess delay risks based on two main dimensions, namely risk impact and likelihood of occurrence. The research method used is descriptive qualitative with a case study approach. Data collection techniques include observation, survey (Likert-scale questionnaire), document study, and archive analysis. The research respondents consist of parties directly involved in the construction procurement process. Data analysis is conducted using descriptive qualitative analysis and risk analysis to determine the level of risk for each procurement activity. The results of this study are expected to provide an overview of critical activities in the procurement process that have the potential to cause delays and serve as a basis for improving construction procurement management in public school building projects in DKI Jakarta Province. Based on the results of the risk analysis, the highest-risk factors are identified and selected, and procurement strategies are then formulated to minimize the risk of delays in public school building construction projects in DKI Jakarta Province.

Abstract

Stakeholders involvement in infrastructure development c.q. Light Rail Transit (LRT) has a significant role since they affect the success of infrastructure management. This paper is primarily aimed to identify key stakeholders and responses that need to be applied to them. On the initial stage, a list of stakeholders was developed using research strategies such as case study and literature review. Sources were then chosen with certain criteria. They were assigned to score each stakeholder on the list. A stakeholder analysis was conducted to obtain a list of key stakeholders that have a significant impact on Jakarta’s LRT.

Abstract

The development of utility-scale solar photovoltaic projects is subject to energy performance degradation risks that may affect project revenues and the ability to meet financing obligations. Therefore, project evaluation should consider the interrelationship between technical and financial performance throughout the project lifetime. This study aims to analyze the relationship between energy production degradation, revenue, Cash Flow Available for Debt Service , and debt service capacity over a 25-year operational period of a utility-scale solar PV project. The study employs quantitative financial modeling based on an assumed annual module degradation rate of 0.5%. The relationships among the key parameters are analyzed using a Rational 2D Response Surface model and analysis of variance. The results show that energy production decreases by 11.3% over the 25-year operational period, while revenue declines by 11.4%, operating expenditure increases by 103.5%, and Cash Flow Available for Debt Service decreases by 36.7%. The Rational 2D Response Surface model indicates strong relationships among energy production, revenue, Cash Flow Available for Debt Service, and debt service capacity, with R² values exceeding 0.99. These findings demonstrate that reductions in energy production and revenue are accompanied by declines in Cash Flow Available for Debt Service and debt service capacity throughout the operational lifetime of the project. Maintaining the technical performance of solar photovoltaic projects throughout their operational lifetime is essential, as energy production degradation directly affects revenue, Cash Flow Available for Debt Service, and debt service capacity. Quality control from the planning stage through construction is therefore an important component of maintaining the project's financial viability and bankability
