By utilising various locating technologies and techniques, Orbital has an extensive record of success in accurately locating buried pipes, conduits and cables. The Australian Standard for utility locating [AS 5488-2013 Classification of Subsurface Utility Information (SUI)] states that the deviation in accuracy for service location is, 500mm vertically and 300mm horizontally. Orbital utilises the Australian Standard as part of our policies and procedures but regularly achieves outcomes that significantly exceed this deviation. However, it must be noted that there may be more than one buried service at any location, within in close proximity to each other and/or buried beneath one another.
Due to limitations inherent in the technology being employed and/or the lack of information in regard to underground services in a particular area, some services may remain undetected despite Orbital’s best efforts. As electronic location is the primary method of identifying and marking services, these conform to a Quality Level B (QL-B) survey, as outlined in the Australian Standard. Exact location and depth of services (QL-A) can only be ascertained by non-destructive hand or vacuum excavation, as appropriate (i.e.pot holing).
We take no responsibility for the location of services, except in accordance with the above disclosure. Overall, any work around underground services involves a degree of risk. As such, service location is a form of risk management and ultimate responsibility lies with the client having been informed of such risks and choosing to proceed on that basis.
The client, or an authorised representative, must be onsite during location work and all site marking is provided for the client listed here only. Reports may be forwarded to a third party, but Orbital takes no responsibility for how the report is utilised by the third parties.
Clients will acquire a set of Dial Before You Dig Plans prior to carrying out any excavation work and reorder plans before they expire. Clients will take all steps necessary to comply with the duty of care statements contained within the correspondence received with the plans. Some asset owners are not members of Dial Before You Dig and these plans should be requested from these owners directly.
