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

This research employs the Value Engineering (VE) method to address these challenges, focusing on high-impact work items such as formwork, floor slabs, walls, and structural elements. Utilizing techniques like Work Breakdown Structure (WBS) and Function Analysis System Technique (FAST), the study systematically evaluates opportunities for cost and time savings while maintaining the project’s functional and quality standards. The results demonstrate that the application of knock-down formwork systems significantly reduces material costs and accelerates construction schedules, achieving up to 20% cost savings in specific work items. The use of local materials further contributes to the optimization process, reducing procurement costs and supporting sustainable practices by minimizing environmental impact. Additionally, the redesign of structural components, such as optimized column dimensions, enhances efficiency without compromising safety or functionality. This study underscores the importance of VE as a collaborative and multidisciplinary tool that integrates technical, social, and cultural considerations. It highlights the critical role of stakeholder involvement, particularly in projects with complex socio-cultural dynamics, ensuring practical and acceptable solutions. By illustrating the effectiveness of VE in overcoming constraints, this research provides a valuable framework for applying VE in future infrastructure projects, especially in areas with similar challenges.

Abstract

The Parte Club Surabaya Building Renovation Project has encountered various problems. These issues arise from multiple factors, primarily due to the complex nature of the structure as it involves renovating an old building. This research aims to identify the dominant risks and allocate the responsibility for managing these risks to the most appropriate party involved. Quantitative research methods were employed for this study. The sample consisted of 18 individuals, including expert staff from the implementing contractor and supervisory consultant. Data collection involved primary data obtained through purposive sampling, with 18 respondents selected. Secondary data included a review of previous similar research literature studies and historical data from earlier projects with similarities. The results of the data processing stage indicated the presence of dominant risks during project implementation and risk allocation. Consequently, project implementation is susceptible to risks identified by analyzing 27 selected risk variables. Six risk variables were dominant in project implementation: construction changes, additional expenses (overheads), project delays, material damage/loss, design errors, and changes to the work schedule. Risk allocation assessment results indicated that 19 risks were allocated to contractors, 3 to owners, and 5 jointly between the owner and contractor (shared). The percentage distribution of risk allocation is as follows: 70% to the contractor, 11% to the owner, and 19% allocated jointly (shared) between the two parties.

Abstract

Heavy equipment is a vital resource in a project, but renting heavy equipment is a costly undertaking. Besides that, a project always has constraints that allow the project completion time to exceed the specified time, and delays will also cause costs incurred to increase. So from the calculation of the productivity of heavy equipment, it is necessary so that the tool can work optimally. From the analysis results, it was found that the productivity of excavators was 154.185 m3/Hour. For dump trucks, it was 37.99 m3/Hour, then calculating the duration of work. For heavy equipment excavators, it took 454 Hours, and for dump trucks, it took 263 O'clock. For the cost of renting heavy equipment from the calculation of the analysis of the cost of renting heavy equipment for excavators, a value of Rp.1,985,200/Day is obtained, while for dump trucks, it is Rp.2,578,000/Day

Abstract

The analysis performed to optimize costs will generate alternatives that will be compared with the initial design, and this analysis can be called value engineering analysis. This research aims to assess the percentage of cost savings that can be obtained by applying the value engineering technique, as well as to evaluate the life cycle cost of various selected material alternatives. The Mosque Construction Project in the South Kalimantan Provincial Government Office Area was chosen as the research object because of cost inefficiency in the architectural work, with a total cost of Rp. 26,857,215,362.63 out of the total project cost of Rp. 55,600,738,764.97. The architectural work will be corrected using Pareto diagram analysis through the value engineering phases, namely the information phase, speculation phase, and analysis phase. From the value engineering analysis results, a savings of 3.65% of the total project value was obtained. The life cycle cost analysis shows that the selected material has a lower life cycle cost value compared to the initially planned material. In addition, the work execution time with the selected material can complete the work on site more quickly

Abstract

Pelaksanan Proyek Jalan Pelabuhan Batulicin merupakan proyek yang penting karena jalan akses The implementation of the Batulicin Port Road Project is an important project because the current access road to Batulicin Port is inadequate. The project execution faced obstacles, including delays in the availability of skilled workers and construction laborers/workers at the project site, delays in the arrival of materials due to required pre-order (indent) and a relatively long manufacturing process at the factory. In the first week up to the third week, the achieved progress was above the planned schedule, and in the fourth week, the achieved progress was below the expected plan. In the fifth week, the achieved progress was above the expected schedule, but in the sixth week up to the tenth week, the achievement progress was again below the planned progress. The fluctuations in progress must be monitored comprehensively in terms of time to estimate the time required for project completion. To resolve these problems, a method used for project control is the Earned Value Analysis (EVA) method. Earned Value Analysis is a tool used in project management that integrates cost and time. The earned value concept presents three dimensions: the physical completion of the project (the percent complete), which reflects the budgeted cost absorption, the actual costs incurred or what is called the actual cost, and what is obtained from the costs incurred or what is called the earned value. The research results show that for time performance (Schedule Performance Index), the value is less than 1, indicating that the project's performance is slower than the planned schedule. The Estimate All Schedule (EAS) value shows a value of 277 days, which is 37 days longer than the planned schedule.
