The Public Infrastructure Engineering Vulnerability Committee (PIEVC) protocol was followed to assess impacts of climate change on the infrastructure and incorporate adaption into the design, development, asset management and decision-making. This assessment was led by BGC Engineering, with input from the Senior Transportation Planner at GNWT-DOT and the Manager of Professional Practice at Engineers Canada. The PIEVC has developed a generalized step-by-step protocol for the vulnerability assessment of infrastructure to climate change. This protocol provides a general framework and can be used for any infrastructure and has the following steps:
- Step 1: Project Definition
- Step 2: Data Gathering and Sufficiency
- Step 3: Risk Assessment
- Step 4: Engineering Analysis
- Step 5: Recommendations
The limitations of the assessment where concerned with the uncertainty in projecting future ground and water temperatures. Unlike air temperatures, ground and water temperatures are more difficult to predict because they depend on other factors such as precipitation, ground water levels, snow cover or vegetation cover. A 1.5 day Vulnerability Assessment Workshop was also conducted in which 15 participants from Operations and Maintenance, Planners, Engineers, Scientists were brought to the table. This workshop included a ½ day highway drive with stops and was very helpful in identifying new elements. The mixing of the groups during different break-out sessions worked well however time was an issue and no pre-selection of crucial combination was carried out.
