Abstract
The Karangjoang-Kariangau Section 3A Toll Road Project in East Kalimantan, Indonesia, aims to connect Balikpapan City with Nusantara, the New Capital City. This 13.4 km project, primarily involving intensive earthwork, utilizes heavy equipment whose efficiency is crucial for enhancing productivity and reducing costs. Our study examines inefficiencies such as unnecessary equipment motion, transportation delays, and extended waiting times—common challenges in lean construction. We implemented a digital monitoring system to compare its effectiveness against traditional manual methods in improving resource utilization and minimizing waste. Findings indicate that digital monitoring, despite the higher initial costs, significantly helps to boost operational efficiency by providing detailed data, then the data can be used to analyze the core of the problem so that a solution is found that successfully reduces idle time by 37% and increasing equipment utilization by 39%. These results demonstrate the substantial benefits of integrating digital technologies into construction management, suggesting a crucial shift towards digital methods to meet the demands of modern infrastructure development effectively. This study underlines the alignment of digital monitoring with lean construction principles, advocating for its adoption to optimize productivity and cost-efficiency in large-scale projects.
