| Abstract |
This study aims to evaluate the quality and productivity of smart construction through empirical analysis utilizing construction automation equipment and to propose strategies for promoting the on-site application of such equipment. The analysis was conducted on major earthwork operations, including slope cutting, pipeline trenching, and soil transport, by comparing the performance of conventional excavators with MG·MC (Machine Guidance·Machine Control) manned and remote-controlled excavators, and traditional dump trucks with autonomous haulers. The results showed that MG·MC manned and remote-controlled excavators demonstrated superior quality and productivity compared to conventional excavators, effectively reducing labor dependency on construction sites. In particular, MG·MC manned excavators achieved higher work accuracy and productivity than standard unit cost estimates, confirming that digital and automation technologies can significantly contribute to improving safety, enhancing operational efficiency, and reducing labor costs. Although autonomous haulers have limited payload capacity, they achieved a sufficient level of productivity and demonstrated strong potential to replace conventional dump trucks as technology advances. This empirical study confirms the feasibility and effectiveness of automation technologies in real-world applications. To further promote the adoption of smart construction technologies, policy support and continuous technological development are required, along with efforts to address technical limitations and legal constraints. |
