If you are a contractor, you would be bestowed with the responsibility of carrying out level 5 utility mapping to locate and detect buried utility services. This is important because you would not want to strike a cable or a gas pipe during excavation. Cable avoidance is the best way to reduce cable strikes and maintain a safe working environment.
A comprehensive mapping of the area is integral to the protection of the workers and the people living near the excavation site. Also, it will save you from having to pay compensation costs. The equipment to be used and how much is to be mapped is decided by the surveyor. For instance, if you are a level 5 utility surveyor, you would be needed to establish technical information systems and site surveying management. For a better understanding, take a look at the different level of surveys.
Level 1 survey: This involves searching existing utility records, which can be consolidated into a single plan in CAD and overlain onto base mapping.
Level 2 survey: At this level, a visual walkover survey is carried out as a part of site visit. Normally, this would be an addition to level 1 survey.
Level 3 survey: Electro-magnetic location survey in both active and passive mode with located services being marked onto the surface of the ground.
Level 4 survey: This is level 3 survey in addition to ground probing radar (GPR).
Level 5 survey: This is a level 3 survey, along with recorded close centred GPR with post data collection analysis and interpretation.
