Subsurface Utility Information (SUI)
Making The Invisible - Visible
Subsurface Utility Information (SUI)
Earth Radar’s team have many years’ experience and are highly trained to locate, verify, survey, map and model subsurface utilities, services and assets.
All our experienced Utility Locators are Dial Before You Dig (DBYD) Certified, Telstra Accredited Plant Locators (TAPL) Accredited and have undertaken our extensive in-house training and assessment procedures.
This enables our clients to actively control the various risks associated with buried services, utilities and other assets including:
- Manage and mitigate OH&S subsurface risk
- Reduced risk of costly variations
- Reduced risk of time overruns
- Greater control over project budget, timeframe and delivery
All our work is compliant with the Australian Standard for Classification of Subsurface Utility Information (SUI) AS 5488—2013. All the above, especially when integrated with our industry leading LatroTM 3D-GPR system, enables Earth Radar to provide our clients with the best understanding of the subsurface across their project sites.
Utility Locating, Mapping & GPR Surveys for Road Reserves & Residential / Commercial / Industrial Properties
The Challenge:
To help facilitate and support the concept and detailed design phase for planned engineering and/or civil works. Earth Radar’s team of locators are some of the most experienced in Australia. Through our in-house training and mentoring programs, our locators are equipped to tackle the most demanding environments to generate deliverables that can be relied upon to be accurate.
Earth Radar can coordinate and deliver the locating, surveying and mapping of all Subsurface Utility Information (SUI) and subsequent Non-Destructive Digging (NDD), also known as potholing, to verify the absolute position of critical assets as required.
By controlling all stages of the SUI locating and mapping process, we are able to deliver an accurate reliable deliverable of superior quality.
The Solution:
Earth Radar will work with the client to decide on the most efficient sequencing of the works to maximize efficiency. Generally it is advised to undertake a two-staged approach if NDD verification is required although this is not always possible/practical.
Our team of experienced SUI locators working closely with our survey teams will locate the existing SUI to Quality Level B (AS—5488) and map this information. The potholing of critical SUI identified is then coordinated and the exposed assets surveyed to Quality Level A (AS—5488) and the data added to a revised version of the existing drawing(s).
The Quality Level A and B information within our drawings provides an additional level of confidence in the existing conditions to be incorporated into the design challenges for the site.
Incorporated Services and Technologies:
- SUI locate to AS—5488 (2013)
- Survey and drafting (including of exposed assets through NDD)
- Non-Destructive Digging
- Full coordination of all phases
- Thorough QA and QC to ensure accurate reliable deliverables
Deliverables:
- AutoCAD .dwg to survey grade accuracies
- PDF plots for field engineers and stakeholders to easily view/access the drawings
- Revised and updated set of deliverables to include the Quality Level A information

Trench/Cable Route Proving
The Challenge:
To help facilitate and support the concept and detailed design phase for the installation of new cable routes/trenches/directional bores.
To install a new cable trench along an alignment within a busy road corridor, Earth Radar are able to coordinate the locating, surveying and mapping of all Subsurface Utility Information (SUI) and subsequent Non-Destructive Digging (NDD), also known as potholing, to verify the absolute position of critical assets as required.
The Solution:
Earth Radar will work with the client to decide on the most efficient sequencing of the works to maximize efficiency. Generally, it is advised to undertake a two-staged approach but this is not always possible/practical.
Our team of experienced SUI locators working closely with our survey teams will locate the existing SUI to Quality Level B (AS—5488) and map this information. The client’s design team can then compare the concept design against the mapped SUI to identify the critical points where more accurate information is required. The potholing of these critical points is then coordinated with the exposed assets surveyed to Quality Level A (AS—5488) and the data added to a revised version of the existing drawing(s). This enables the design team to generate their final detailed design.
The above approach maximises the value to the client and reduces unnecessary costs. The Quality Level A and B information within the drawings also provides an additional level of confidence and is an effective risk management tool for the civil teams responsible for breaking ground to install the new cable/asset.
Incorporated Services and Technologies:
- SUI locate to AS—5488 (2013)
- Survey and drafting (including of exposed assets through NDD)
- Non-Destructive Digging
- Coordination of Traffic Management sub-contractor
- Full coordination of all phases
Deliverables:

Reality Capture / LiDAR Survey of Confined Spaces
The Challenge:
Where spatial information is required for manhole chambers that are classified as confined spaces.
Access to these chambers is highly restricted due to the extreme risk associated with entering confined spaces and the potentially working around hazards such as high-voltage cable joints.
The Solution:
Earth Radar have developed a workflow to enable the survey of manhole chambers using a Terrestrial Laser Scanner. This removes the requirement to access the chambers entirely. The resulting point clouds are geo-referenced so that spatial information can be extracted at survey grade accuracies and shown in relation to the above ground information, mapped SUI and proposed designs. The point cloud information can also be provided to the client in a software bundle that enables viewing of the point cloud data without any specialized software installed; allowing access to this high value data-set to any interested party from the comfort of their desk.
Incorporated Services and Technologies:
- Terrestrial Laser Scanning of High Risk Confined Space Manhole Chambers
- Geo-Referencing of Point Cloud Data-Sets
- Extraction of Survey Grade Spatial Information for Manhole Chambers
Deliverables:
- Geo-Referenced Point Cloud in Autodesk and other formats as required
- Point Cloud Data Bundle for Project Team/Stakeholder Access
- AutoCAD drawing and 3D modelling of manhole chamber’s spatial information related to existing control/above ground drawings
RFID Marker Balls / Programming, Installation & Survey
The Challenge:
To help manage the long term security and risk profile of newly installed high-value buried assets (such as optic fibre conduits, high pressure gas mains or high voltage electric cables).
Installation of RFID Marker Balls enables the accurate positioning of critical points along the route of buried assets. They are particularly suitable for high-value buried assets or buried assets that would be difficult to relocate once installed through traditional methods. The use of RFID Marker Balls allows critical way-points along a route to be relocated to help mitigate the risks associated with subsequent civil works that may take place within the vicinity of these buried assets.
The Solution:
Earth Radar coordinate the procurement and programming of the required RFID Marker Balls ready for installation. A client specific message can be programmed onto the RFID Marker Balls. These balls were then installed at pre-determined locations along the assets route either as the asset is installed prior to backfilling or by setting out the locations and potholing. Once installed Earth Radar undertake an as-built survey and verification of each individually installed RFID Marker Ball and generate an AutoCAD drawing showing their location as well as generate a GIS output compatible with the clients existing GIS software environment.
As required, Earth Radar then provide locating services to map the locations of installed RFID Marker Balls.
Incorporated Services and Technologies:
- Procurement of RFID Marker Balls
- Programming of RFID Marker Balls
- Installation (including NDD/potholing if required) and as-built survey
- Generation of as-built data
Deliverables:
- Programmed RFID Marker Balls with client specific content
- AutoCAD drawing showing locations of installed RFID Marker Balls
- GIS data-set of installed locations and associated attributes compatible with clients existing software environment

Earth Radar are able to coordinate the locating, surveying and mapping of all Subsurface Utility Information (SUI) and subsequent Non-Destructive Digging (NDD), also known as potholing, to verify the absolute position of critical assets as required.
The Solution:
Earth Radar will work with the client to decide on the most efficient sequencing of the works to maximize efficiency. Generally it is advised to undertake a two-staged approach but this is not always possible/practical.
Our team of experienced SUI locators working closely with our survey teams will locate the existing SUI to Quality Level B (AS—5488) and map this information. The client’s design team can then compare the concept design against the mapped SUI to identify the critical points where more accurate information is required. The potholing of these critical points is then coordinated with the exposed assets surveyed to Quality Level A (AS—5488) and the data added to a revised version of the existing drawing(s). This enables the design team to generate their final detailed design.
The above approach maximises the value to the client and reduces unnecessary costs. The Quality Level A and B information within the drawings also provides an additional level of confidence and is an effective risk management tool for the civil teams responsible for breaking ground.

Our range of deliverables vary from simple PDF reports through to high-resolution 3D digital models compiled from multiple data sets. The data and drawings we produce can be delivered for use within industry standard CAD environments (such as AutoCAD, MicroStation or 12d) or within your organisations existing GIS environment (such as ArcGIS or MapInfo).
Our team are experts at bringing different data sets together and presenting them in a clear, concise and easy to interpret way.
Non-Destructive Digging (NDD) aka ‘potholing’ - Proving, Validation and Verification
The Challenge:
When designing new infrastructure around existing subsurface assets, services and utilities, sometime the positional accuracies that can be achieved by EMI and GPR (Quality Level B locates) are not sufficient. In these instances, the only way to validate and verify the exact position and depth of a service or asset is to excavate and expose it.
Through undertaking a Quality Level A investigation through Non-Destructive Digging (NDD) or ‘potholing’, it is possible to record and map the critical subsurface features and assets to survey grade accuracies to ensure the information used to inform the decision making process is of the highest order of accuracy.
The Solution:
With Earth Radar being part of the VAC Group, we are able to coordinate and manage any NDD requirements while maintaining a ‘one stop shop’ solution for our client.
By utilising the VAC Group’s hydro-excavation trucks to pothole onto the identified critical targets, our team can verify and survey the exposed assets and then integrate this higher order accuracy information into the existing CAD drawing, refine the exiting 3D model or generate a report/dataset for import into the clients existing software/model(s).
VAC Group’s hydro-excavation trucks are designed, tested and built in Australia and as such are able to operate in and withstand the unique challenges presented by Australia’s climate and conditions.
Through providing all services through our in-house specialists, Earth Radar and VAC Group aim to make our clients life as straight forward as possible, with a single consistent point of contact to manage the project from concept to completion.
