What must be determined before the opening of any excavation?

Before commencing any excavation, it is crucial to determine the exact location of all underground utilities. This information is fundamental to ensure the safety of workers and the integrity of existing infrastructure. Striking a utility line during excavation can lead to serious accidents, service interruptions, and costly repairs. Identifying the precise location of utilities—such as electrical, water, sewer, and gas lines—allows for proper planning and implementation of safety measures, thereby reducing the risk of hazardous incidents.

While safety regulations are important, they are typically part of the overall planning process once utilities are identified. Timeframe for completion and type of soil present are also significant factors in project planning but come into play after establishing the underground utility locations, which are the primary concern before beginning excavation. Understanding where utilities are located helps to inform decisions on how to proceed safely with the excavation work.
