Abstract
High-rise characteristics of skyscrapers in different countries, including Russia, are given. There are promising projects of constructing new skyscrapers. These high-rise structures have their own design features, they are objects of a high responsibility level, and require arranging reliable geodetic support to be constructed and operated. The specifi cs of high-rise construction geodetic support are noted. The role of high-quality support increases with the amount of fl oors. The errors of the formwork removal to the installation horizons are considered. The accuracy requirements for geodetic operations and precision of creating a planned reference network are formed. The methods of transmitting plane coordinates to high horizons and the disadvantages of the currently used technologies are shown. Recommendations for the use of new geodetic technologies in high-rise construction are formulated. The ways of high-rise structure fl uctuations geodetic monitoring based on using video displacement sensors, GPS receiver, video hydrostatic sensors and inclinometers are presented. Measurements are performed with special computer programs. The proposed geodetic technology has been tested in Russia in a number of construction sites. Recommendations on the use of modern geodetic technologies in high-rise construction, depending on the height, are presented.
