Construction Survey Technology For Super Tall Building Of Changsha A1 District Office

For example of Changsha A1 district office building project,from four aspects of construction control measurement,vertical passing measurement,detail construction measurement and dynamic deformation monitoring were studied and discussed. In terms of construction control measurement, the precision control measurement technology for super tall building was successfully summarized.In terms of vrtical passing measurement, take actions of selecting the minimum amount of deformation of the timing of sunshine to cast(optional), To limit Weather conditions when measured(to choose),a gradual reduction of measuring height of the laser vertical instrument(Approaching), to solve the key problems of measurement technology for super tall buildings.In terms of detailed measurement, summed up simple and practical methods of detailed measurement. In terms of dynamic deformation monitoring, through real-time monitoring and data analysis of the building, to predict deformed condition of the building in advance. Take corrective measures to achieve a measure provided by the actual situation, to reduce the likelihood of rework. Through application of this technology, reserving the technological innovation, for the projects and companies, providing a valuable experience for the construction of similar measurement and control large-scale building projects. It has significant technical and economic benefits and social benefits.
