What best describes the function of 'Andamio' in building projects?

The function of 'Andamio' in building projects is best described as a temporary support. The term 'andamio' refers to scaffolding, which is used during construction or renovation work to provide a platform for workers and materials. It allows access to different heights safely and is essential for tasks such as painting, masonry, or installation of building components. As a temporary structure, it is erected for the duration of the construction project and dismantled once the work is completed.

In contrast, permanent structures are built to last and serve as foundational elements of a building, decorative features don't contribute to the structural integrity but enhance aesthetics, and a foundation layer refers to the base that supports the entire structure, which is a completely different aspect of construction than scaffolding. Hence, identifying 'andamio' specifically as a temporary support captures its key role in construction workflows.
