Abstract

This study examines the impact and risk management strategies in the construction of East Surabaya Hospital, focusing on technical, time, cost, and environmental aspects. Using a comprehensive mixed-method approach, the research integrates SWOT analysis and Failure Mode and Effects Analysis (FMEA) with Environmental Impact Assessment (AMDAL) documentation to ensure a thorough evaluation of risks. Extensive data collection was conducted through stakeholder interviews, structured questionnaires, and field observations to identify significant risks across multiple dimensions. The findings reveal that environmental risks constitute 45% of total project risks, stemming from air and noise pollution and community disruptions, while technical risks, including equipment failures and material delays, contribute 35%. Temporal and financial risks, though less dominant, showed a cascading effect on overall project efficiency. Implemented risk mitigation strategies, such as preventive equipment maintenance, trusted supplier contracts, dust control measures, and transparent community engagement, successfully reduced technical risks by 25% and environmental impacts by 30%. Statistical analysis demonstrated a strong positive correlation between risk mitigation efforts and project success, with a p-value of 0.02, highlighting the effectiveness of these measures. The study underscores the importance of integrating environmental considerations with technical, temporal, and financial risk management strategies. It provides valuable insights for developing adaptive and sustainable risk management frameworks for urban hospital construction projects, ensuring project success while fostering environmental sustainability and community acceptance.

Abstract

Efficient construction project management is crucial to ensure quality and timely completion within budget constraints, especially for large-scale infrastructure projects. This study examines the application of the Critical Path Method (CPM) in accelerating the construction schedule of the Malaka Regency Regent's Office. The project faced various challenges, including frequent delays caused by design changes, unpredictable weather conditions, labor shortages, and inadequate material or equipment supply. These challenges often disrupted the progress and efficiency of the project, necessitating an effective solution to mitigate potential time and cost overruns. To address these issues and align project progress with the original plan, CPM was utilized to identify critical paths, eliminate lag times, and optimize the overall project schedule. Using CPM analysis and Microsoft Project 2019 software, the project's original duration of 180 calendar days was successfully reduced to 100 calendar days. This acceleration was achieved by streamlining interdependencies between critical activities and optimizing work schedules without increasing project costs. The findings highlight the significant role of CPM in achieving time savings while maintaining the planned budget of IDR 94.59 billion. Moreover, this study demonstrates that proper scheduling, coupled with optimization techniques, can significantly enhance the efficiency and effectiveness of construction projects. These results underscore CPM's potential as a valuable tool for project managers to ensure timely completion without compromising quality or incurring additional costs. This research contributes to the growing body of knowledge in construction project management and offers practical insights for managing similar projects in the future

Abstract

The construction industry plays a crucial role in developing infrastructure, including essential facilities like hospitals. In recent years, the design and build method has gained popularity due to its ability to integrate design and construction phases under a single contract, offering efficiency in both time and cost. However, alongside its advantages, this method brings numerous risks that can significantly affect project outcomes, especially in terms of completion delays. This research aims to analyze the influence of risk factors in design and build on the time performance of hospital construction projects. The design and build model is one of the most commonly used contract methods in construction projects due to its effectiveness in simplifying the implementation stages. However, the application of this method is often faced with risks that can affect project completion, particularly in time management. This study employed data collection techniques using questionnaires on planning and construction factors. The collected data were analyzed using Pearson correlation to determine the relationships between variables and multiple linear regression to measure the impact of risk factors on the project's time performance. The results show that construction factors have variables with significant and strong relationships to project success, while planning factors have some variables with weak and insignificant relationships. Therefore, risk management efforts should focus on variables with strong and significant correlations to ensure the project's optimal success.

Abstract

The construction of the Malaka Regency Regent's Office has faced significant challenges, including frequent delays in project completion due to various factors such as design changes, unpredictable weather conditions, labor shortages, and inadequate materials or equipment. These issues have led to inefficiencies in time and cost management, emphasizing the need for effective project management strategies. This study applies the Critical Path Method (CPM) to analyze the project timeline, identify the critical path, and propose measures for project acceleration. By employing CPM, the project schedule was meticulously reviewed and optimized, resulting in a reduction of the initial planned duration from 180 calendar days to 100 calendar days. This acceleration was achieved by minimizing lag times between critical activities, reallocating resources, and implementing time-cost trade-off strategies, all without compromising the quality or scope of the project deliverables. The results demonstrate the effectiveness of CPM in streamlining construction project timelines and mitigating delays. Additionally, this study provides a practical framework for addressing time and cost overruns in construction projects, particularly in the context of public infrastructure development. By highlighting the integration of project management tools like CPM, this research contributes to the broader understanding of efficient scheduling practices and offers actionable insights for similar projects in the future.

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.
