Townsville City Council (TCC), one of the largest local government authorities in Queensland, is responsible for managing and maintaining one of the largest roads networks in Australia. TCC regularly commissions civil engineering consultancy, Pavement Management Services (PMS) to conduct road condition surveys and sophisticated laser scans of the road surface.
Together, these have provided TCC with an accurate picture of its road assets. However, to better manage public scrutiny and enhance its overall asset management approach, TCC also needed to make more proactive use of detailed data that had been collected.
To do this, the council began looking for a versatile asset management software solution that would allow it to carry out enhanced pavement modelling; put strategic works programmes in place that take account of shifting budgets, and ultimately ensure better allocation of available funds to ongoing road maintenance plans. Its existing system could not meet these requirements. It had no way of achieving clear and transparent analysis of its whole data set. Often, it needed to use summarised data to calculate road conditions – and therefore struggled to obtain an in-depth and accurate insight into the state of its pavement assets.
To rectify this, PMS recommended the council used Yotta’s visualised asset management software solution, Horizons, now integrated into the PMS technology suite, and rebranded as part of the consultancy’s offering to existing and prospective customers across Australia, following its recent partnership agreement with Yotta.
Reaping the Rewards
Thanks to PARMMS, TCC can visualise, explore and analyse all its data in a single platform. By using PARMMS’ Analysis module, the council can quickly and efficiently run different investment scenarios and make the case either for increased investment or to protect existing budgets.
This, in turn, allows TCC to start to optimise its approach to asset management. Different ways of allocating spend will of course result in different results. With the help of PARMMS however, TCC can try out different scenarios to evaluate the optimum approach to capital spend. That could either mean saving money on a treatment and maintenance programme over a given period while still delivering a consistent level of service, or, alternatively, improving the level of service delivered to the community while maintaining spend at a consistent level.
Looking to the future, PARMMS can further enhance its approach to asset optimisation by carrying out an ongoing review of the data it holds and calibrating itself accordingly. In other words, it can improve its overall capability as more data comes into the system.
PMS and Yotta have already used PARMMS to set up deterioration curves showing how pavement changes condition over time. As PARMMS gathers more data, it will be able to create a more informed localised deterioration curve, capable of providing invaluable insight to council decision-makers as they prepare their future asset maintenance plans.
1. High level of public scrutiny of road network
2. Difficult to supply all the different stakeholders, both technical and non-technical, with data that they could clearly visualise and understand
3. Data is not readily available for decision-making
4. Difficulty with ongoing configuration of the model to local conditions
5. Rich data sets that were collected were summarised to calculate road conditions which did not therefore reflect the true picture of condition
