Asset capturing at eThekwini Electricity, South Africa
Aurecon, finding innovative solutions
As part of developing and implementing an integrated infrastructure asset management business plan for eThekwini Municipality in eastern South Africa, eThekwini Electricity embarked on an initiative to capture and model all of its electrical network assets. Aurecon assisted with the data collection and modelling exercise. The project team had to find innovative solutions to a number of issues inherent to an exercise of this nature, including:
Planning and executing a very comprehensive field exercise spanning an area of over approximately 2,300km2 ensuring high quality of data
Developing a connected network model with more than 900,000 network equipment items recorded from the field
Defining the asset structures for the purpose of an equipment and asset register
Propagating information through all relevant systems with a view on future system integration
The project team took a different approach whereby office modelling relied on domain specialists, a well-structured data capture process and state-of-the-art information systems in support of a largely unqualified data capture and modelling team. The engineers and supervisors initially trained new data capturers and thereafter assisted with ad hoc queries and interpretation of data where the data capturers did not have the know-how.
Data modelling was carried out in a Geographical Network Information System (GNIS) supporting real connected network modelling. This greatly enhanced modelling quality and added value to the deliverable as a result of functionalities enabled from connectivity.
eThekwini Electricity realised the effort involved in enabling proper asset management, and will in future reap the benefits of investing in data capturing, implementing processes, systems and continuous training ensuring that through the unequivocal support of management the journey towards excellence in asset management is successful.
