Sample interview questions: How do you ensure that a bridge design is resilient to climate change impacts?
Sample answer:
- Design for increased flooding: Climate change is expected to lead to more frequent and severe storms, which can cause flooding. Bridges should be designed to withstand these higher floodwaters, by raising the bridge deck, using larger culverts, and protecting the bridge piers from scour.
- Use stronger materials: Climate change is also expected to lead to more extreme weather events, such as hurricanes and earthquakes. Bridges should be designed to withstand these forces by using stronger materials, such as high-strength concrete and steel.
- Include expansion joints: Bridges should be designed with expansion joints to allow the bridge deck to expand and contract with changes in temperature. This will help to prevent the bridge from cracking or buckling.
- Use sustainable design practices: Bridges should be designed to be sustainable, by using materials and construction methods that have a low environmental impact. This can include using recycled materials, using energy-efficient lighting, and planting native vegetation around the bridge.
