The Study on Efficiency Analysis of Estimation of Amount of Earthworks Utilizing BIM

Abstract

Recently, methods to accurately select an inflection point for the curve of topography that fits well with the actual topography are developed, which reduces errors. However, the existing inconvenient and inaccurate methods are still used for the estimation of the amount of earthworks in the construction field the BIM-based process is applied to improve the existing inconvenient and inaccurate methods in the construction field. However, most studies were conducted focusing on architectural constructions and even in earthworks, only research on overall project management or the estimation of quantities has been conducted. Therefore, this study is intended to suggest the process of estimating the amount of earthworks based on BIM that is more efficient and accurate than the existing estimation methods of the amount of earthworks in the field of earthworks It is necessary to study on the guideline to suggest the accurate criteria that a hands-on worker can refer at the phase of early introduction.
