Verticality control is one of important monitoring items during tall building construction. Compared with traditional survey equipments like total station (TS) or laser plummet, RTK-GPS is high-tech instrument which is little affected by weather, visibility, limit of observation angle/distance or human error. In this paper, a RTK-GPS monitoring system was developed and tested at high-rise building and bridge pylon under construction. The developed RTK-GPS shows similar survey results with TS, speedy installation and quick measurement, which is expected to be widely used for large structures as well as tall buildings. |
