Estimation of earthwork volume for Klarik-Teluk Buton road construction in Natuna Regency, Riau Island

Abstract

Earthworks (land cutting and filling) are crucial initial stages before undertaking the road and bridge projects. These work processes are carried out to achieve the road's desired elevation and soil density according to the project plan. Land’s cutting and filling volumes in the road projects can be calculated based on topographic mapping. Further, the data on land’s cutting and filling volumes can be used to determine the total required soil for construction work. This study attempts to estimate the total volumes of excavation and landfilling works along the Klarik-Teluk Buton road development in Natuna Regency, Riau Islands Province. The method employed to calculate excavation and landfilling volumes for the Klarik-Teluk Buton Road Development is the composite volume method, which involves calculating the difference in elevation between the original and planned surface contours using AutoCAD Land Desktop 2009 software. The calculations show an excavation volume of 40.112 m3 and a landfill volume of 142.867 m3 for the area of the Klarik-Teluk Buton Road. Based on the calculations, it is found that there is a shortage of 102.755 m3 of landfilling soil for the Klarik-Teluk Buton road development.
