The City of Burlington owns and manages nearly 200 bridges and large culverts within its jurisdiction. Engineering Department personnel are responsible for the inspection, structural evaluation and for the planning and rehabilitation activities associated with each of these structures.
Staff in the Infrastructure and Data Management (IDM) group is responsible for maintaining the Bridge Management System (BMS), responding to public inquiries, as well as retaining qualified engineers and/or specialists to provide engineering services to assess the condition of the various structures.
Staff from IDM and Design & Construction (D&C) work together to establish rehabilitation priorities, and introduce the rehabilitation projects into the 10 year Capital Budget and Forecast.
The key activity for successful Bridge and Culvert Management is regularly scheduled structure inspections. Inspections assist staff in determining the current asset condition, and are useful from a budget planning and life-cycle analysis standpoint. Structure inspections are typically routine (biennial detailed visual inspections) or non-routine (emergency / special circumstance) in nature. The City will also conduct Detailed Condition Inspections (Condition Surveys), which are more in-depth examinations of whole structures or specific structure components. These inspections are intended to assess the safety and serviceability of the structure, and are typically quantitative in nature.
The inspection process requires planning and organization for effective implementation. This ensures that inspection protocols for bridges and culverts are adhered to in a way that best represents operating at a Best Practices Level.
