Introduction CQ University (CQU) Students and Central Highlands Regional Council (CHRC) Partnership timeframe (November 2016- June 2017)

‘A Deeper Dive into Asset Management’ By Raitt Mcleod and Brodie Young

Business Objectives CQU Students CHRC “Gain an understanding of fit-for-purpose engineering within a local government organisation”. CHRC “Attain flexible resources with untrained mindsets to apply asset management fundamentals within business decisions”.

Strategic Thinking ‘Cradle-to-grave’ ‘Fit-for-purpose’ engineering Proactive works- ‘maintenance’ vs. ‘renewal’

Misc. Group Involvement Site visits/ Project involvement including: Water and Sewerage Treatment Material Sourcing Road Pavement Rehabilitation Capital works- Upgrade unsealed-sealed Much more infrastructure, etc.- culverts, bridges, footpaths, K & C

Transport Business Process Model (TBPM) Review of: Inspection Methodologies Defect Criteria Develop: Dynamic Cone Penetrometer ARRB Roughometer Collector Application Transport Comprehensive Revaluation Update entire Sealed Roads via desktop Determine Sample Size Unsealed Plan and complete inspections Evaluate 228 segments 20% U-Network

Why Review the TBPM? Prior TBPM methodologies for the collection, analysis and storage of data were limited and aspirational given the resources available i.e.- subjective and not fit-for-purpose. Funding decisions historically based on financial valuation data, i.e.- remaining useful life and service potential index. Limited reliable condition data for transport network in particular unsealed network.

Primary Focus TBPM- Unsealed Network Research, evaluate, implement and reflect on; Defining defect criteria Determining methodologies to evaluate defect criteria Determining methodologies of data storage Whilst considering all factors contributing to ‘CHRC best suited’ decisions i.e.- resources and community levels of service

Dynamic Cone Penetrometer (DCP) Used to determine gravel depth objectively. Determine strength characteristic of pavement layers. Simple, cost-effective, user friendly and fast results.

DCP Continued… Noticeable Layer Change i.e.- in situ material Pavement Wearing Layer i.e.- gravel Change of Layer i.e.- Gravel depth is approx. 65mm!

ARRB Roughometer III (Roughometer) Invested in by CHRC to eliminate subjectiveness for evaluating roughness i.e.- driver and vehicle. User friendly and effective. Data collection can be used for quick analysis or project level.

Roughometer continued… Very Poor Adjust communities level of service - Roughness (scale 1-5) to match International Roughness Index (IRI). GPS-Roughness integration Multiple Roughness reports generated for each test. Poor Roughness (IRI) Fair Good Very Good Distance (km)

Comprehensive Revaluation Update entire sealed network as per new TBPM parameters Gather 20% baseline data for unsealed 228 random segments best representing the unsealed network as per RHS Diagram Best VFM for Council given limited resources i.e.- time and man-power Approx. 30-40 days work

Comprehensive Revaluation Results (Unsealed) We inspected approximately 228 road segments spread across the entire region, highlighted in red on the map to the right hand side. The results, shown on the left, provides council with up to date condition related data for a sample of the roads in the region. On average the condition of our unsealed network is in a relatively good condition with only one hierarchy above a condition 3 and the two largest hierarchies, Rural Access and Rural Collector, below condition 3. As the valuation and condition assessment process is continued over time, we can build on the data and get a better understanding of the condition of our assets and how long they are lasting. This will assist with the planning of maintenance to ensure our assets last and the renewal of assets. 1= Very Good 2= Good 3= Fair 4= Poor 5= Very Poor

Comprehensive Revaluation Results (Unsealed) Assigning these results to the rest of the unsealed network we found some interesting outcomes… Change in total length of unsealed roads: (-26.4km) Change in pavement area from increased width: (1,237,000 sq. metres) Increase in councils asset values. Minus three flat tyres…. and a DCP rod stuck in the road ( we got it out eventually) This shows that previous versions of asset management and condition assessment did not accurately represent the assets in the field.

The Bigger Picture * Improve council operations * Inform strategic decision making Helps inform the community Assists in maintaining and improving level of service in the region

The Bigger Picture “Inform strategic decision making” Implement targeted maintenance to extend service life of assets Understand the condition of assets and budget accordingly Identify asset consumption patterns- create long term maintenance and renewal plans Accurately and confidently report on the financial value of assets (including whole of life costing)

The Bigger Picture “Helps inform the community” Assist the community in understanding the health of Transport Assets across CHRC to help inform prioritised communal decisions. Routine maintenance and renewal programs to inform the community of works i.e.- reduce complaints, improve customer service and efficiency. Engaging with the community to develop Levels of Service, based off objective data and prioritisation. Objective asset condition data to support maintenance schedule Data driven

The Bigger Picture “Assists in maintaining and improving level of service in the region” Better understanding of asset condition will lead to well timed maintenance and renewals Long term planning of maintenance optimises the outcome and increases efficiency Healthy assets support communities, trade and tourism in the region and improves user safety

Conclusion Leading the way in simple condition assessment practices for unsealed roads Through research and development of highly accessible tools Practiced and refined during the comprehensive revaluation CHRC now has a better processes in place to manage their assets: The condition of our assets The value and future cost of our assets Making data-driven decisions – (lead to cost saving and efficiency gains) Aim to practice and refine our processes further and implement more regularly CHRC has taken a step in the right direction by researching and trialling basic condition assessment tools to inform and support current asset management systems
