AS5488:2019 CLASSIFICATION OF SUBSURFACE UTILITY INFORMATION (SUI)
AS5488
The Australian Standard (AS 5488) is intended to provide utility owners, operators and locators with a consistent method of classifying subsurface utility information.
This Standard provides a framework for the classification of subsurface utility location and attributes information in terms of specified quality levels for the management of subsurface utilities.
The application of this standard is intended to provide greater public safety and reduce costly infrastructure damage through a greater understanding of the different accuracies regarding utility location information.
SUBSURFACE UTILITY ENGINEERING (SUE)
Subsurface utility engineering (SUE) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
The combined method of using utility locating and geophysical equipment, Vacuum Excavations, Marking Methods, Survey & Project Coordination as techniques to accurately communicate details of the underground utilities buried on any project site.
Cable Locates' provides Certified DBYD Location Technicians; extensively trained & experienced in Subsurface Utility Engineering, in practice and delivery.
UNDERGROUND LOCATING & CRITICAL SUPERVISION
Cable Locates & Consulting utilise the most advanced technology, for surveying of underground utilities and services.
Experienced Locators & market leaders in the industry, providing asset detection and full feature investigation.
Certified Locators for Underground Utility Damage Prevention, APA & ATCO Critical Gas Supervision.
Our Location Crews hold various and a vast site & specialised induction status.
Knowledge & Safety Management a priority on any project.
SURVEYING
Cable Locates & Consulting are Certified and experienced Location Technicians working closely and maintain trusted relationships with specialist contractors in Surveying as well as in-house Survey.
Cable Locates ensures work is carried out in compliance with our QMS and Standard procedures & protocols.
Cable Locates can provide Survey Deliverables on all large or small scale projects:
SURVEY - FULL FEATURE SERVICE
PLAN DRAFTING - A-Spec, D-Spec / R-Spec
AS CONSTRUCTED DRAFTING
CIVIL EXCAVATION
VACUUM EXCAVATION
Cable Locates & Consulting have undergone extensive research and design to develop our custom built 4WD Vacuum Excavation trucks. This custom design allows the highest cost efficiency ratio.
Specialised use’s include:
Non-destructive utility potholing
Non-destructive vacuum trenching
Non-destructive utility pit cleaning
Non-destructive excavations
Non-destructive exposing solutions
The primary advantage of vacuum excavation is the non-destructive nature and ease of use.
Other advantages include:
Use in tight spaces: minimal vehicle footprint
Versatile and expandable: Vacuum tube can be extended to different lengths to meet excavation requirements
4WD: Our Fleet of vehicles & trucks are equipped for the challenging terrain of Western Australia.
GEOPHYSICAL INVESTIGATION & 3D
Cable Locates & Consulting offer a complete package.
Electromagnetic Conductivity and Resistivity Survey’s, combined with Ground Penetrating Radar Surveys and RTK GPS Systems, there is a service available to accomplish any project requirement.
Electromagnetic Surveys measure the ground conductivity and resistivity via Electromagnetic Induction. Both passive and active is useful in comparing various materials on the ability to conduct electric currents.
Any environmental and geo-technical service can be focused to the scope of work required for individual project outcomes.
As us about our IDR STREAM C service
BEST PRACTICE QUALITY LEVELS
The 5Ps - Industry Best Practice to Prevent Damage
PLAN - PREPARE - POTHOLE - PROTECT - PROCEED
QUALITY LEVEL D
(The least accurate level and if used on its own has a high rish of damage) QL-D information is generally obtained from existing records provided by utilities as a result of a Dial Before You Dig enquiry being lodged. In many cases the asset depicted on the plan is in a schematic format only and intended only to indicate its presence.
QUALITY LEVEL C
(Low accuracy and a high risk of damage) QL-C is described as surface feature correlation or an interpretation of the approximate location and attributes of a subsurface utility asset using a combination of exiting records and site survey of visible evidence - For Example, you can see the pit lids shown on the plan but the actual position of the Underground Connection between pits is still assumed!
QUALITY LEVEL B
(Significant risk reduction) QL-B providers relative subsurface feature locations in three dimensions. The minimum requirement for QL-B is relative spatial position, this can be achieved via an electromagnetic frequency location device. An electronic location provided by a DBYD Certified Locator to QL-B standard would have a maximum horizontal tolerance of plus or minus 300mm and a maximum vertical tolerance of plus of minus 500mm.
QUALITY LEVEL A
(Meets location accuracy standards for minimum risk when excavating) QL-A is the highest Quality Level accuracy and consists of positive identification of the attribute and location of a subsurface utility at a point to an absolute spatial position in three dimensions. It is the ONLY quality Level that defines a subsurface utility as “Validated”
