Preventative and rehabilitative maintenance of assets is key to maximizing the functional life of highways, bridges and related structures.
As asset management specialists, we protect the longevity of road infrastructure through multi-decade mandates. Typically, this involves monitoring the condition of pavements, structures, and related highway infrastructure (signage, lighting, etc.) as well as forecasting needs, planning maintenance, and rehabilitating assets in a timely manner. Our responsibilities can be summarized as a continuous “plan-do-check-act” cycle that continuously evolves as needed to meet changing demands (traffic volumes, weather patterns, market innovations, etc.)
Expert planning and coordination
The biggest challenge in managing major assets—like the 275-kilometre stretch of the Trans-Canada highway that we oversee in New Brunswick—is coordinating maintenance, repair and rehabilitation efforts so that traffic disruptions are minimized. Our teams perform annual and multi-year forecasting based on historical and current condition assessments, which are used to plan timely interventions to maximize the useful life of the assets at the lowest overall cost. It’s a complex process with many variables that require seasoned and knowledgeable professionals to produce adapted and effective results.
Short-term efforts for long-term benefits
We view preventative maintenance as an important component of our asset management plans. For example, every spring we completely flush the bridge deck and barrier walls on the William R. Bennett Bridge to remove de-icing salt residue from the structure. We believe that minimizing structural concrete exposure to chloride residues goes a long way in protecting the structure, which would be costly and disruptive to rehabilitate.
Prevention is supported by visual inspections, seasonal maintenance and ensuring that assets are kept up-to-date with the best intelligent transportation systems available on the market.
