Road Asset Management

… is a holistic approach to managing road assets under total life-cycle strategy. Asset management strategies are not task oriented, but instead are driven by preestablished priorities and level of service goals for each asset category. Consequently, performance measures are determined by assessments of outcomes in terms of asset condition; asset function; safety; and costs to achieve levels of service over time. Statistical information is compiled and evaluated relating to types of assets, usage, condition level, threshold of intervention, future construction, maintenance and operating costs, and long term impacts.

Why Asset Management?

Pierce County Road Operations Division Mission Statement:

To maintain, operate and preserve Pierce County’s roads at full function, 24/7, as safely and efficiently as possible.

Maintenance Management Maintenance management provides a framework for developing maintenance plans, tracking work accomplishment and preparing reports that compare planned and actual work performance. The framework includes the typical management functions of planning, organizing, directing and controlling.

8 Elements of PWU Road Ops AM System Level of Service – Establishes an agreement with policymakers on services to be provided with an given a complete understanding of  the costs to deliver that service. Ranges of Level of Service (LOS) should be easy to distinguish (i.e. – visual) A,B,C,D and F to imply  Good, Fair, Poor, etc.

Inventory – An accurate inventory is critical for effective asset management. The lelve of inventory detail should be based on several  factors; 1)being able to accurately access the value of assets. 2) being able to effectively maintain and operate the asset. 3) at least  down to the level at which replacement of the asset is accomplished and assessed. 4) being able to accomplish the measurement of the  performance of the asset based on the LOS established for the asset. 5) being able to correlate cost data to the asset. Condition Assessment – To effectively manage an asset requires a systematic assessment of the condition of the asset. This is  required before the asset manager can determine if the established LOS goals are achieved. It is common for an asset to have both an  operational condition measurement and a physical deterioration condition related to the repair/replacement of the asset. The  condition measurement is directly related to the LOS goals established for the asset. 

Usage Data – Asset usage data is often useful in managing resources used to maintain, operate and preserve the asset. Use of the  asset may be a factor in deterioration of the asset over time and can significantly affect the condition of the asset. It is important to  collect the types of usage data that affect the physical performance of the asset, its deterioration over time, and/or its operational  performance. Its important to correlate usage data with performance data by location, date and time. Cost Data – Information on the initial cost and on‐going operation and maintenance costs of an asset.  Replacement Model – A replacement model is used to determine the time, type and method to replace an asset. The model uses a  set of criteria or steps to work through to decide the appropriate replacement point. The model can be a software tool and/or formula. 

Risk Assessment – The Risk Assessment process is an estimate of the probability and severity of the failure of an asset to the overall  system and safety concerns to others. 

Performance Measures – Simply put, performance measures provide a series of indicators, expressed in qualitative, quantitative,  or other tangible terms that indicate whether current performance of an asset is reasonable and cost effective.
