Performance modelling (also known as condition modelling or deterioration modelling) is a structured approach to determining the future condition and needs of assets including pavements, bridges, utilities and buildings. 

With performance modelling we use structured decision making processes to:

• Generate appropriate maintenance actions
• Forecast conditions or outcomes
• Determine the best combination of treatments and outcomes within various budgets

With a “snapshot” of a client’s asset inventory and condition, we determine the future usage of the asset, and use mathematical relationships to predict the future performance of the asset.  Possible treatments for each asset component or element are tested using engineering-based logic. The resulting strategies are compared in terms of cost and user-defined benefit streams.

The process typically involves the analysis of significant historical data to gain a better understanding of local performance and conditions for a client, and to refine the models or develop new models specific to the asset where necessary.
