What is the first step that needs to be taken prior to starting any excavation work?

Prior to starting any excavation work, the crucial first step is to contact the local utility companies. This step is essential for ensuring safety and compliance with regulations, as underground utilities such as gas, electricity, water, and telecommunications lines can pose significant hazards if struck during excavation. By notifying utility companies, you can access vital information about the locations of these buried installations, which helps to prevent accidents, service interruptions, and costly damage.

It's important to understand that while notifying neighbors, selecting digging equipment, and assessing soil type are relevant actions in the context of excavation, they should occur after confirming the safety and presence of utilities. Failing to perform this first step can lead to severe consequences, making it the priority before any physical work begins.
