Underground Service Locating and Mapping
HCS provides underground service locating specialists for your infrastructure project. Our CERTLOC-accredited and experienced team uses the latest technology and techniques to deliver a complete picture of the underground services on your project. Our technology can identify, confirm and map the underground services present on your project. Our data delivery can provide anything from simply 2D overlay all to way to an augmented reality solution.
It is critical prior to any excavation or penetration work that the exact underground service locations are validated to ensure the safety of this critical infrastructure and the personnel on the ground working closely with these services. Meticulousness care must be taken to avoid service strikes to ensure safety and to avoid substantial financial impacts on your business. Our team is experienced in the locating and protection of these critical underground services. Our underground service locating specialists provide your business with factual information on service locations to ensure a total visualisation of the underground infrastructure on your site.

Delivery of data is of extreme importance when it comes to GPR as it is now so much more than a recognise and mark process. Raw location data is processed in house and converted into any electronic format that is required.
Heavy Construction Solutions provides a start to finish program for your underground service location needs, from arranging the DBYD information to handover of a comprehensive electronic file and detailed drawings of critical underground infrastructure on your project.
With more than 11 years of experience and 2,500+ sites investigated across Australia, HCS is a CERTLOC Certified Locating Organisation and a member of the National Utility Locating Contractors Association of Australia (NULCA), working to ISO 9001, ISO 45001 and ISO 14001 certified management systems. If your project also requires below-slab investigation, our concrete scanning service works alongside underground service locating to give you a complete picture before you cut, core or excavate.

Frequently Asked Questions
What is underground service locating and why is it needed before excavation?
Underground service locating is the process of identifying, tracing and marking buried utilities — electrical cables, gas, water, sewer, stormwater and telecommunications lines — before any digging, drilling or construction work begins. It protects critical infrastructure, keeps site workers safe, and helps avoid the cost and delay of an accidental service strike.
What's the difference between GPR and electromagnetic (EML) locating?
Electromagnetic locating (EML) traces conductive utilities — metal pipes and live electrical or communications cables — by detecting the signal they carry or conduct. Ground Penetrating Radar (GPR) is used for non-conductive assets such as plastic gas or water pipes, empty conduits, and underground voids, by sending radar pulses into the ground and reading the reflections. HCS uses both methods, matched to the site conditions and utility types present.
Do you locate private services as well as public utilities?
Yes. A Dial Before You Dig (DBYD/BYDA) request only returns records for public utility assets — it doesn't cover privately owned infrastructure such as site-specific stormwater, on-property electrical runs, or older undocumented services. HCS's on-site locating identifies both public and private services so you get a complete picture before excavation.
What areas do you service?
HCS provides underground service locating across Melbourne and Victoria, with additional offices in Newcastle, NSW and Brisbane, QLD.
What standard do your locates comply with?
Our locating and reporting follows AS 5488.1:2022, the Australian Standard for Classification of Subsurface Utility Information, which defines the quality levels (QL-A to QL-D) used to record the accuracy and reliability of located utility data.
What do I receive at the end of a locate?
A detailed report and drawings covering the located services, delivered in the format that suits your project — from a simple 2D overlay through to 3D asset mapping.
Are your locators certified?
Yes — HCS's underground service locating teams are CERTLOC-certified (Certified Locating Organisation), Australia's recognised accreditation for subsurface utility locating.
