What is the purpose of using half frames on sloping grounds for scaffolding?

Using half frames on sloping grounds is primarily aimed at mitigating grade changes. When scaffolding is erected on uneven or sloped terrain, it can be challenging to ensure stability and safety. Half frames help to accommodate variations in the ground surface by providing a level platform for the scaffolding to rest on. This adjustment is crucial for maintaining the structural integrity of the scaffolding and ensuring that workers can operate safely at varied heights.

Implementing half frames allows the scaffolding to conform to the slope, reducing the risk of collapse or instability due to uneven weight distribution. This also aids in maintaining proper working heights and access for laborers, contributing to overall work efficiency and safety on site. In contrast, the options related to avoiding baseplates, cutting costs, or enhancing aesthetics do not directly address the specific safety and structural requirements posed by sloping ground conditions.
