Before starting work you must:-Make sure you have plans of the underground services in the area. This may not always be possible for emergency or unforeseen works. Remember that service connection cables from the main to a building or a street lamp may not be shown.
-Use a cable and pipe locator to trace electricity cables and metal pipes. You should have been trained how to do this. If in doubt or if you have any difficulty get help and advice.
-Mark the positions of the cables and pipes using paint or other waterproof marking on the ground - or using short pegs and marker tape in soft ground.
-Look for signs of service connection cables or pipes, e.g. a gas or electricity meter box or a service connection entry into a house or street lamp
-Hand dig trial holes (as many as necessary) to confirm the position of services in close proximity to the area of your work. This is particularly important if there are plastic pipes that cannot always be found by locator.
-Ensure sub-contractors are fully briefed and that they have clear copies of the marked up drawings on site.

Remember:
Cables tiles and tapes may have been moved by other contractors and utilities and they may not be buried at standard depths. MAKE NO ASSUMPTIONS!!
