A Scenario-Based Simulation Model for Earthwork Cost Management Using Unmanned Aerial Vehicle Technology

Risks are involved in every aspect of earthwork projects. This paper specifically discusses the cost risk associated with volume calculation such In design phase, it is not possible to accurately predict quantity per soil type underground site. As a result, there uncertainties excavation that may cause overrun. There need for an innovative method forecast, control, monitor, and manage from phase completion. is, however, calculating using digital surface model method. The can be acquired GPS unmanned aerial vehicles (UAV). proposes simulation which able analyze, monitor based on so stakeholders gain actual quickly accurately. Monte Carlo applied type, resulting range outcomes cost. developed was verified by applying case project. Throughout project, successfully monitored maintained below maximum expected However, final last almost reached cost, indicating monitoring. By periodically comparing result excavated obtained UAV, proposed assist controlling overrun developing strategies during life cycle.
