Abstract

Super high-rise buildings are being built more and more in the world and in Vietnam. Currently, foreign experts are presiding over most of the geodetic work during the construction of super high-rise buildings in Vietnam. Vietnamese technicians are only allowed to participate in the implementation at the request of these experts. Therefore, in Vietnam, it is necessary to have a full research on geodetic work in the process of building super high-rise buildings. This article presents the research results of a group of lecturers in the Geodetic Department, Hanoi University of Civil Engineering on the ability to combine terrestrial and satellite measurements, which are measured by total station and GNSS, in geodetic work when building super high-rise. The research results are the process of building and data processing one-level spatial networks, determining three-dimensional coordinates in a unified coordinate system, step by step ensuring accuracy throughout the construction process, exploiting super high-rise buildings.
