  • How are roads selected for reconstruction or rehabilitation?

    Arterial and collector roads with the lowest net condition rating for sewer, water, road, trees, sidewalks, street lights, traffic signals are entered on our Infrastructure Replacement List and discussed at Internal and External Utilities Coordinating Committee meetings. Once assessments have been completed, priorities are based on the following:

    • The remaining life of each pavement section is predicted
    • The best rehabilitation method is determined for each road section that requires work in a future year.
    • The available budget is factored in.
    • An optimization routine is run to determine the most cost-effective mix of projects for the available funding.
    • Adjustments are made to minimize impacts as much as possible.
  • How does London compare to other Cities?

    In 2013, 54% of London roads were rated Good to Very Good. In comparasin to other Cities in Southwestern Ontario, London fits right in the middle of percent averages.

  • How are roads condition rated?

    We use a PQI (Pavement Quality Index) rating scale from 1-100 in a 4 year repeating cycle, in combination with sewer and water video inspections.

  • When are trenchless technologies used?

    On average, 15-20 kilometers a year of sewers and watermain are trenchlessly lined in London. These trenchless programs allow for the deferral and avoidance of large capital costs and the minimization of social impact by avoiding open cut construction.
