Knowing the location, depths and routes of existing pipes, cables and other buried infrastructure is a principal requirement for those engaged in feasibility studies, design, construction and asset maintenance activities.


As experienced utility mapping and detection specialists, we reduce uncertainty and project risk due to old, incomplete, missing, ambiguous or unavailable ‘as-constructed’ utility data, by locating underground services with a high degree of accuracy through the use of EMI, 2D and 3D GPR and vacuum excavation.


We undertake projects ranging from small-scale locating of individual utilities for connection or maintenance purposes, to comprehensive borehole clearance surveys and utility asset mapping for industry and construction.


The benefits of using these methods include the:

  • Identification of the routes, types and depths of buried services,
  • Identification of potential conflicts, enabling more effective planning and design,
  • Reducing the costs associated with the digging of speculative trial holes, and
  • Mitigating the risk of cable strikes and damage to third party services

Topographical Surveys are used to map the shape, form, level and geographical position of the earth, both natural and unnatural. The term ‘earth’, can mean anything from a small garden to a national park, farm track to a motorway or from a small building plot to multi hectare development.


Vac Group understands that each site presents specific risks and challenges, however our highly skilled survey team can tailor survey requirements to meet each site’s specific survey needs. Our survey standards meet Australian Survey Standards SP1 and local Government Standards G71 (Control Surveys) and G73 (Detail or Topographical Surveys). These surveys can be coordinated locally or can be linked to MGA and AHD survey networks throughout Australia. Using the latest technology and equipment, our surveyors can produce high quality survey models/drawings and services which include:


  • Small to large scale land surveys;
  • GPS surveys;
  • Triangulation and contour modelling;
  • Boundary Overlays (CAD);
  • Civil Works (Setting Out) construction site works;
  • Trig levelling to 5mm accuracy;
  • Surveying of Underground Assets to the relevant Australian Standard including Class Accuracy.
  • Establishing or working within Control Survey Networks; and
  • Survey for future design needs.


All our drawings and detailed information are digitally mapped using Autocad dependant on your required final digital format. We create Digital Terrain models with Meta Data files including relevant Model Validation in accordance with 

AS/NZS ISO 9001 quality management.
