处理放线工作的不同阶段，即现场主要框架（导线、网格等）的测量、参考线（基线）的放线、参考线到其他楼层的转移（管道铺设）、位置点的放线以及这些不同阶段的找平程序。给出测量和放线时的允许偏差值，并建议使用某些程序和仪器。

Deals with the different stages of the setting out work, i.e. the measuring of the primary framework (traverses, grids, etc.) on the site, the setting out of reference lines (baselines), the transfer (plumbing up) of reference lines to other floors, the setting out of position points and the levelling procedure for these different stages. Gives values for permissible deviations when measuring and setting out and recommends certain procedures and instruments to be used.
