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.
