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

Contract administration is a crucial aspect of successful construction project implementation, particularly for government projects with high levels of complexity, accountability, and risk. This study aims to analyze the implementation of standard contract administration procedures in the Presisi 5 POLRI Project, identify its level of compliance with applicable regulations, and examine obstacles and improvement efforts. The research method used was a descriptive qualitative method with a case study approach. Data collection techniques included reviewing contract documents, field observations, and interviews with relevant parties. The results indicate that, in general, contract administration procedures have been implemented according to standards, but several obstacles remain in aspects such as documenting work changes, time management, and coordination between parties. This research is expected to provide practical contributions as evaluation material and recommendations for improving the quality of contract administration in government construction projects..

Abstract

The construction industry in Indonesia still faces various classic problems such as time delays, cost overruns, low labor productivity, and high levels of waste in project implementation. One construction management approach developed to address these issues is Lean Construction. This concept focuses on eliminating waste, increasing value for project owners, and continuously optimizing workflows. This study aims to examine the implementation of Lean Construction in improving construction project efficiency. The research method used was a literature review and conceptual analysis of Lean Construction principles, methods, and tools commonly applied to construction projects. The study results indicate that the application of Lean Construction through waste identification, the Last Planner System, continuous improvement, and collaboration between project parties can improve time efficiency, cost efficiency, and work quality. Therefore, Lean Construction can be used as a strategic approach in construction project management, oriented towards improving overall project performance.
