Automated earned-value tracking

Efficient and effective construction progress tracking is critical to construction project management. Recent attempts to improve progress tracking have focused mainly on automation. Using technologies such as 3D-imaging1,2,significant progress has been made. However, one limit of these approaches is the focus on counting objects3or milestones rather than value, and contractors typically state a clear preference for earned value tracking over design-object-oriented quantity tracking for buildings and industrial facilities. Therefore, in this paper,we proposean automated progress tracking sys-tem that transforms objects to their earned values.
