Abstract

Construction project management is a complex process that involves the integrated management of time, cost, and quality to achieve the desired results as planned. Effective supervision is needed so that the project can run according to the target without experiencing time or cost losses. One method that can be used for project supervision is Earned Value Management (EVM). EVM is a method used to measure project performance by comparing work plans, completed work, and actual costs. This method aims to accurately measure project progress, identify deviations in schedule and cost, and provide guidance in decision making. This research focuses on the application of the EVM method to the Batu Ampar - Sp.3 Muara Wahau Road Preservation Works construction project in East Kalimantan Regency. This road section is a strategic route connecting Samarinda City in East Kalimantan with Tanjung Selor City in North Kalimantan. In this project, handling landslide points is a priority, one of which is the Bore Pile and Foam Mortar work method. The results of this study are expected to provide a real picture of the application of EVM in managing construction project performance and improving the efficiency of time and cost management.

Abstract

This paper examines the efficiency of steel material use in commercial building roof trusses. The analysis was conducted by comparing several types of steel profiles using manual calculations and structural software, based on Indonesian National Standards (SNI) standards. The goal was to identify the most material-efficient configuration without compromising strength and stability. The results indicate that selecting the right profile can save up to 25% on material, resulting in a more economical and efficient design.

Abstract

This study compares the cost estimation time for structural work between conventional methods and 5D BIM for the Precision 5 National Police Building Project. Using a quantitative approach and case study, data was obtained from project documentation and simulations. The results show that 5D BIM significantly accelerated the estimation process without compromising accuracy.

Abstract

The use of Building Information Modeling (BIM) technology in construction projects has had a significant impact on the work processes of civil engineers. However, this advancement also raises new ethical challenges. This paper examines the application of professional ethics in the use of BIM from the perspective of civil engineers. Through a qualitative approach and literature review, it was found that while BIM improves efficiency and collaboration, integrity and professional responsibility are still required to prevent data misuse or violations of ethical principles. Ethics are key to maintaining project quality and accountability in the digital age.

Abstract

In general, the condition of drainage systems in various cities across Indonesia is facing a wide range of problems. An effective drainage system plays a crucial role in preventing floods and waterlogging, especially in densely populated urban areas such as Depok City. With the rapid pace of urbanization, the drainage infrastructure in Depok is confronted with multiple challenges, both technical and environmental in nature. This article examines the current state of the drainage system in Depok by utilizing reliable data and documenting real-life occurrences observed in the field. Through an in-depth analysis of rainfall data, the physical condition of drainage channels, and several flooding incidents that have occurred in recent years, this paper aims to provide a comprehensive overview of the situation. It also seeks to offer practical and strategic recommendations to improve drainage management in the area, thereby supporting better urban planning, disaster mitigation, and sustainable infrastructure development in the long term.
