Curtain wall construction is a complex project, which requires careful measurement and setting-out steps. This paper will introduce the survey and setting-out steps of curtain wall construction in detail, including survey basis, survey methods and survey tools.

Measurement basis

We take the center line and elevation provided by the civil engineering unit as the benchmark for measuring and setting out. The design of glass curtain wall should be consistent with the building axis. Therefore, we need to accurately measure the completed civil structures.

Measurement method

We adopted a variety of measurement methods, including external contour measurement, column external plane positioning, column axis positioning and column elevation positioning. These methods ensure the precision and accuracy of curtain wall construction.

Measuring tool

We use theodolite, level and line drop for accurate measurement. These tools ensure the precision and accuracy of curtain wall construction.
