    Protecting The Asset

    Identifying the precise location and condition of underground services and assets is essential before undertaking any ground works, both as a safety precaution and to protect the asset from damage.

    For many asset owners, this information may not be available due to old infrastructure not being mapped correctly or detailed plans being lost or inaccessible.

    In most cases, plans provided by an asset owner only indicate the presence of infrastructure within the vicinity of the project site and do not pinpoint the exact location. Accurate location in plan and depth of the services assists to mitigate risk to the services during the ground improvement works.

    Service Location

    Our highly skilled and trained service locator team has Dial Before You Dig Certification and Telstra Accreditation. Mainmark’s service location work is undertaken in accordance with Australian Standard AS5488-2013 Classification of Subsurface Utility Information (SUI).
