Abstract

A few examing method are introduced for the upper structural perpendiculdrity in construction,structure and project to be completed, check and acceptance etc. in tall-storey building. By some project examples their precision analyses and comparisons are carried out by the different examining methods.
- upper structural perpendicularity,
- plumbing apparatus,
- main monitoring point,
- vertical projection
