As the traffic is growing steadily, the infrastructure has to be in appropriate conditions. With the presence of very high resolution 3D laser scanner with its ability to capture large amount of data in short time and limited disruption to traffic, laser scanners seem to be an excellent tool to monitor deformation behaviours of the traffic infrastructure. Unlike the conventional method using discrete points, point clouds obtained from terrestrial laser scanning can later converted to surfaces to provide better deformation analysis as stated by Zogg and Ingensand (2008). In this study, the point cloud of the flyover was scanned in two epochs utilizing the state-of-the-art Leica ScanStation C10 laser scanner. Using Geomagic Qualify software, the first epoch point cloud were later transformed to surface and 3D comparison were carried out between two epochs via surface comparison where the distance calculated from second epochs point cloud to the first epoch surface obtained as the deformation analysis. This result was presented graphically using coloured surface comparison. The results obtained shows that the flyover is intact and no major movement were detected. Apart from that, with the full coverage of the flyover from the point clouds obtained, it is also possible for the under-clearance measurement via cross sectioning. From the cross sections created, the minimum clearance of the flyover measured was 5.318m. Thus, with the dense point cloud data from laser scanners is an advantage for surveyors to compare and execute deformation monitoring area-wide rather than using discrete point monitoring conventionally fahmimoksen UTM 101 p.
