When Should You Call Utility Inspection Services?

Before you start subsurface work or planning your project, you should call a private utility locator or concrete scanning specialist who can mark out the underground utilities and features in your work area. It is vital to understand the precise positions and estimated depths of utility lines and features at the early design stages, so you can plan around the underground utilities and features when performing subsurface work.   This knowledge will help make the accurate placement of buildings, cuts, drilling, foundations, post supports, signs, trees, soil borings, and other project components possible. Utility locators assist project planners in determining where utility lines need to be avoided or relocated to prevent hazards for workers and machine operators. If you choose not to schedule utility locating services, the result could be harmful to your jobsite or company. There are compounding effects that could impact budgets, performance, project schedules, reputation, safety, etc. that could delay or cancel the entire project.
