Case Study: Main Roads Western Australia improves timber bridge investment planning with Deighton Associates

Main Roads Western Australia operationalizes timber bridge modeling in 16 weeks with Deighton Associates

Main Roads Western Australia (MRWA) faced challenges with forecasting the condition of and optimizing investment for its large portfolio of timber bridges, which relied on manual asset planning processes. To modernize its approach, MRWA initiated a project with vendor Deighton Associates to develop a consistent, data-driven platform for long-term decision-making.

Deighton Associates implemented a two-phase Bridge Deterioration Model project, operationalizing a framework within dTIMS that integrated GIS and Life Cycle Cost Analysis. The solution provided MRWA with improved visibility into long-term bridge performance, the ability to perform multi-year scenario testing, and more informed investment planning for its unique timber structures.
