Abstract: The no-column steel canopy structure of Qingdao North Railway Station is a space system composed of Steel columns and planar tube truss. It’s the exposed steel structure and demands good appearance. The choice of measurement methods and error control measures are the key to ensure the steel structure mounting accuracy. Considering construction environment and components in the process of the steel structure construction, special methods of measurement including Pan observation position and components observation position were chosen. Through adjusting the installation error by retesting the processes, the verticality and straightness of steel installation were effectively ensured and installation accuracy satisfied the requirement of design and specification.

Keywords: Qingdao North Railway Station; planar tube truss; measurement methods; error control
