Underground Services Mapping Melbourne
HCS Underground Services Mapping - Call 1300 859 027
Heavy Construction Solutions (HCS) converts on-site underground service locating data into accurate, engineer-ready digital records. Using survey-grade GPS/GNSS positioning, our CERTLOC-accredited technicians capture the exact location, depth and classification of every located service and translate it into 2D CAD drawings, GIS layers and 3D BIM models that your design, construction and asset management teams can rely on.
Underground Services Mapping and Digital Utility Records
Underground services mapping closes the gap between locating in the field and using that information with confidence back in the office. Every asset we map is classified in line with AS 5488 (Classification of Subsurface Utility Information), giving you a clear, auditable record of survey quality and confidence level for each service - critical for design coordination, safe excavation planning and long-term asset registers.
Poor or missing utility records are one of the leading causes of service strikes, redesign costs and project delays. Our mapping outputs give your team a single, trusted source of truth for every underground asset on site, ready to be layered directly into your existing design, GIS or asset management software.

- GIS-ready shapefiles and geodatabases for asset management systems
- AS 5488-compliant Quality Level classification for every mapped asset
- 3D BIM models for design coordination and clash detection
- Digital handover packages for council, utility authority and client records
GIS and CAD Data Formats
- AutoCAD (DWG/DXF) drawings compatible with existing design files
- ESRI shapefiles and geodatabases (GIS)
- Revit and BIM-ready 3D models
- Survey-grade GPS/GNSS coordinate data (MGA/GDA2020)

Whether you need a single site mapped or an ongoing asset register maintained across multiple projects, our mapping team works alongside our underground service locating crews to deliver one continuous, verified dataset from the ground to your design software.
Our underground services mapping works hand-in-hand with our underground service locating and concrete scanning services to give you a complete picture before you design, cut, core or excavate. Learn more about HCS or view our full range of site investigation services.
Frequently Asked Questions
What is underground services mapping?
Underground services mapping is the process of converting located underground service data into accurate digital records - including CAD drawings, GIS layers and 3D BIM models - so design, construction and asset management teams have a reliable digital record of every buried asset on site.
How is underground services mapping different from underground service locating?
Locating is the on-site process of finding and marking buried services using GPR and electromagnetic detection. Mapping takes that located data and converts it into accurate, georeferenced digital deliverables - CAD, GIS and BIM files - that can be used in design software, asset registers and council submissions.
What is AS 5488 and why does it matter for mapping?
AS 5488 is the Australian Standard for Classification of Subsurface Utility Information. It defines Quality Levels (A-D) that describe how accurately and reliably each mapped service has been located and positioned, giving your project a clear, auditable confidence rating for every asset in the dataset.
What file formats do you deliver?
We can deliver AutoCAD (DWG/DXF), ESRI shapefiles and geodatabases, Revit/BIM models, raw GPS/GNSS coordinate data (MGA/GDA2020), and PDF or image-based reports, depending on what your design or asset management system requires.
Can underground services mapping be used for design coordination and clash detection?
Yes. Our 3D BIM-ready models allow design and services engineering teams to check new infrastructure or structures against existing underground services early, reducing the risk of clashes, redesigns and costly changes during construction.
Do you provide GIS data for asset management systems?
Yes. We deliver GIS-ready shapefiles and geodatabases that can be imported directly into most council and utility asset management platforms, giving you a long-term digital register of underground infrastructure.
How accurate is your underground services mapping?
Positioning is captured using survey-grade GPS/GNSS equipment and classified against AS 5488 Quality Levels, so every asset in your dataset comes with a documented confidence rating for horizontal and vertical accuracy.
What areas do you provide underground services mapping in?
HCS provides underground services mapping across Melbourne, Newcastle and Brisbane, with the same CERTLOC-accredited team and technology used for our underground service locating services.
