8.2 Structural Works

The modules shall be pre-assembled before proceeding with the following inspection and finishing works.

在进行后续的检查和整理工作之前，模块应预先组装好。

LEVEL AND ALIGNMENT水平和对齐

The level and alignment shall remain within the tolerance limits.

水准和对准应保持在公差范围内。

VERTICALITY垂直性

Finished module shall maintain its verticality not greater than the stipulated tolerance for PPVC.

成品模组应保持其垂直度不大于PPVC规定的公差。

BULGING隆起
