True or False: Precision excavation is usually only necessary for footings.

Precision excavation refers to the careful and accurate removal of soil to create a specific shape or depth, which is essential not only for footings but also for various other construction and engineering applications. While it is indeed critical for footings, particularly in ensuring that they are adequately sized and correctly aligned, precision excavation is also necessary for foundations, trenching for utilities, and other structural elements where precise measurements directly impact the stability and safety of the construction project.

Therefore, stating that precision excavation is usually only necessary for footings is limiting and does not fully encapsulate its broader application in construction. This function plays a vital role across multiple areas beyond just footings, highlighting the importance of precision excavation in overall project success and structural integrity.
