Projects concerning road, railway, tunnel and pipelines include a large amount of earthworks which is often delayed or has considerable cost overruns. This study presents a method to assist earthwork planning, by extracting separate 3D objects of cutting and filling, at-taching schedule information and visualize these in commercial BIM 4D software. The 4D method was applied and verified in the re-scheduling of a linear infrastructure project which is one of the German governments selected pilot projects before implementing BIM requirements in 2020.The study indicated that the 4D visualization enable information flow between projects participants. The paper gives suggestions to the level of information detailing standardized open data format should be able to contain in regards of facilitating the use of BIM 4D information visualizing in future linear infrastructure projects.
