Abstract: The conventional method of coordinate decomposition calculation based on manual operation is not efficient and there may be erroneous judgement due to human fallibility in responseing to the gradually increasing construction requirements and the needs of special products application. In this paper, the problem of data correction and qualification evaluation in the dimensional accuracy control for the construction of the complex structures similar to "roller coaster" is effectively solved with the help of automatic coordinate decomposition and redirection, which has accumulated a comprehensive experience of project application in the high-accuracy surveying, inspection and deviation corrections for the similar complex spatial steel structures.

Key words: spatially irregular steel structure, local coordinate decomposition, high-accuracy surveying, connection by bolted flange
