Abstract

This research aims to analyze the cost estimation of risk mitigation in the construction project of the Pamekasan Regency Regional General Hospital. Construction projects are highly complex and often face multiple risks, including technical, environmental, and management factors, which can significantly affect cost efficiency and project completion time. Failure to address these risks appropriately can lead to budget overruns, prolonged delays, and compromised construction quality. The research employs a quantitative approach using the Probability and Impact Matrix and Severity Index to systematically identify, categorize, and assess the impact of construction risks. The findings reveal that the total estimated cost of risk mitigation reaches Rp. 290,450,000, which primarily covers additional labor, high-quality material procurement, and the application of technology for project monitoring. To mitigate these risks, several key strategies have been implemented, including stricter contract management, improved stakeholder communication, enhanced workforce capacity, and advanced project monitoring techniques. Furthermore, digital-based monitoring systems and early risk detection mechanisms are suggested to prevent major disruptions in the project workflow. By implementing effective mitigation strategies, the project is expected to operate more efficiently, minimize unnecessary costs, and adhere to the planned construction schedule. The study highlights the importance of proactive risk management in large-scale infrastructure projects, providing valuable insights for contractors, project managers, and policymakers involved in hospital construction. These findings emphasize the need for continuous evaluation and adaptation of risk mitigation strategies to ensure successful project execution.

Abstract

This research addresses the critical issue of insufficient budget allocation for Occupational Safety and Health (OHS) systems in construction projects, specifically in the Rubaru 1 Elementary School building project in Sumenep District, Indonesia. The study explores how limited financial resources for safety measures, such as personal protective equipment (PPE), worker training, and health facilities, affect the implementation and effectiveness of OHS systems. The urgency of this research lies in the growing need to allocate adequate resources to OHS, as insufficient funding increases the risk of workplace accidents, delays project timelines, and raises costs. Previous studies, including Lestari et al. (2023) and Saragi & Sinaga (2021), have emphasized the positive impact of adequate OHS budgets on reducing accidents and improving productivity. However, a gap exists in research regarding the specific cost components required for effective OHS implementation, especially in relation to construction projects with limited budgets. This study fills this gap by analyzing the key cost components for OHS and their direct impact on worker safety and project performance. The findings will provide valuable insights for construction companies to optimize their OHS budgets and enhance safety measures. It also contributes to the development of industry standards and practices for OHS management in future construction projects.

Abstract

The construction of the Regional General Hospital Dr. H. Slamet Martodirdjo in Pamekasan Regency faces several challenges, particularly concerning high-level risks that may impact project success. This study aims to identify and analyze major risks affecting project completion and propose effective mitigation strategies. Using a survey method, data were collected from key stakeholders and processed using the Severity Index and Probability and Impact Matrix to assess risk levels. The findings identified 25 potential risks, with eight categorized as high-level risks: implementation method errors, difficulties in installing cross foundations, delays in critical path tasks, late material procurement, labor shortages, non-compliance with occupational safety regulations, lack of teamwork among workers, and adverse weather conditions. These risks significantly impact the project timeline, budget, and overall quality. The study also reveals that poor coordination among stakeholders, inefficient risk management practices, and regulatory constraints contribute to project delays. To mitigate these risks, strategic planning, improved procurement management, workforce training, and strict adherence to occupational safety regulations are recommended. Additionally, the adoption of technology-driven solutions, such as digital monitoring systems and e-procurement platforms, can enhance project oversight and efficiency. By implementing a systematic risk management framework, construction projects can minimize potential disruptions, ensure timely project delivery, and maintain cost efficiency. The findings of this study provide valuable insights for project managers, contractors, and policymakers in the construction industry, particularly for large-scale healthcare infrastructure projects. A proactive risk mitigation approach is essential to achieving successful project execution and sustainable infrastructure development.

Abstract

This study aims to analyze project cost and time acceleration using the Crashing Method by adding three hours of overtime work and additional labor. Delays in construction projects often lead to budget overruns and inefficiencies, making acceleration techniques essential for ensuring timely project completion. The research evaluates cost efficiency by comparing the total project budget before and after implementing the Crashing Method. Using both qualitative and quantitative approaches, this study examines the impact of different acceleration strategies on cost increase and time reduction. The findings indicate that project completion time can be significantly reduced using both methods; however, overtime results in higher cost increases compared to additional labor. While overtime provides immediate acceleration, it incurs higher expenses due to increased labor wages, whereas adding workforce results in gradual but more cost-effective acceleration. Furthermore, the study underscores the importance of selecting the appropriate acceleration approach based on project constraints, workforce availability, and financial considerations. Effective resource allocation, labor management, and risk assessment are critical factors in minimizing costs while maximizing efficiency. By analyzing the trade-offs between cost and time, this study provides valuable insights into the optimal strategy for project acceleration in construction management. The findings offer practical recommendations for contractors, project managers, and stakeholders to optimize resources and maintain budget control while ensuring project completion within the scheduled timeframe.

Abstract

The implementation of construction projects often faces various risks that can lead to delays, cost overruns, and decreased quality of work. One example occurred in the project to build a dormitory for students of the Riyadlus Sholihin Islamic Boarding School in Probolinggo City, which experienced a time deviation despite acceleration efforts. This shows the importance of implementing systematic risk management to identify and address potential risks from the beginning of project implementation. This study uses a descriptive quantitative approach through the dissemination of questionnaires and interviews to related parties in the project. The analysis was carried out using the Severity Index method to calculate the level of probability and impact of each risk, as well as the probability and impact matrix to determine the level of risk significance. The dominant risk is then further analyzed to determine mitigation actions. The results of the study showed five risks with a "Very High" level, namely the preparation of the wrong work method, poor coordination between parts, the accuracy of completing work within a certain duration, poor planning and scheduling, and low labor productivity. Mitigation strategies are developed to reduce the impact of these risks, including through training, improved communication, the use of planning software, and strengthening the monitoring system. This research makes a real contribution to the risk management of construction projects in a more effective and structured manner.

Abstract

Bridge infrastructure plays an important role in supporting connectivity and regional economic growth. However, in their implementation, bridge construction projects often face delays due to technical factors such as weather, soil conditions, as well as managerial and coordination constraints. One of them occurred in the Purworejo Bridge construction project in Mojokerto Regency which experienced a delay in progress of -14.88% in the 12th week of implementation. This delay requires accelerated efforts so that the project is not included in the critical contract category. This study seeks to examine the approach of accelerating implementation time through the Crashing method through increasing working hours (overtime) and calculating costs efficiently to mitigate delays. The methodology used includes the formulation of a network using Microsoft Project, the identification of critical paths through the Critical Path Method (CPM), and the calculation of acceleration costs based on Cost Slopes. The results of the analysis show that the acceleration of work can be achieved both technically and economically. This method allows the project to reduce delays, thus removing them from the classification of vital contracts. The study significantly improved the decision-making process for the timely and cost-effective implementation of development projects.

Abstract

Indonesia is in an active seismic area prone to earthquakes, including the city of Surabaya, which is crossed by the Kendeng Fault. Many modest homes in the area were built without considering earthquake resistance standards, thus posing a high risk of damage and casualties. This research aims to evaluate the reliability level of simple house buildings against earthquakes in the Tandes, Asemrowo, and Sukomanunggal Districts, West Surabaya, which are crossed by the Kendeng Fault. The methods used are Rapid Visual Screening (RVS) based on FEMA P-154 guidelines and Fault Tree Analysis (FTA) as a deductive approach to map the causes of structural vulnerability. The results showed that none of the 30 housing units met the safety criteria; 76.7% of buildings require follow-up evaluation, and 23.3% are classified as unsafe. The dominant factors affecting vulnerability include non-standard foundation conditions, the absence of structural fastening elements, the use of wall materials without reinforcement, and the irregularity of building geometry. These findings indicate the need for technical intervention through structural retrofit, public education about earthquake-resistant buildings, and the formulation of regulations for the construction of residential houses in earthquake-prone zones. The combination of RVS and FTA methods has proven effective in providing a comprehensive overview of the structural condition of existing buildings and can be used as the basis for seismic risk mitigation strategies in urban areas.
