Why is it crucial to mark underground utilities before excavation?

Marking underground utilities before excavation is crucial primarily to avoid accidental strikes that can result in injuries or service disruptions. By identifying the locations of utilities such as gas, water, electricity, and telecommunications, workers can clearly see where digging can safely occur. Striking these utilities can lead to dangerous situations, including gas leaks, electrocution, and flooding, which pose significant risks to workers and the public. These accidents can not only cause physical harm but can also lead to costly service interruptions and repairs.

Additionally, while marking utilities may indirectly support aspects like maintaining utility efficiency or possibly streamlining excavation, the foremost and most critical concern is safety. Ensuring that excavators are aware of what lies below the surface helps mitigate the risk of damaging infrastructure and promotes a safer working environment.
