NDEA is Greater Sydney’s subterranean safety specialist, protecting underground infrastructure.
Below the surface there is a vast city of subsurface utilities, buried infrastructure supplying our gas, water, sewerage, electricity and communications. Whilst essential, these subsurface utilities pose a danger for any excavation or building work as any damage to the utilities can result in expensive damage claims, delays and possible injury to workers or the public. It is therefore critical to safely and quickly locate all the underground infrastructure before any work on site is commenced.
Most utility providers require that any contractor working with near their underground infrastructure, prove the existence and location of the utility, and some require the utility to be fully exposed before commencing any works. To achieve this ‘Dial Before You Dig’ (DBYD) recommends the use of non destructive excavation (potholing/trenching) as the best practice method to identify, locate and protect any subsurface utility.
