18.8.4. Bridge and Dam Inspection

Try these first

1. 1.

   What type of imagery do drones provide for bridge and dam inspections?

   Hint

   Think about the clarity and detail of the images.

2. 2.

   What technology is used to detect heat in structures?

   Hint

   Consider what is used to visualize temperature differences.

3. 3.

   What major advantage does thermal imaging provide in structural inspections?

   • It detects light intensity
   • It identifies moisture issues
   • It measures structural load

   Hint

   Think about what heat sensors are used for.

4. 4.

   True or False: Aerial surveying reduces the need for personnel to physically inspect hazardous areas.

   • True
   • False

   Hint

   Consider the role of UAVs in dangerous areas.

5. 5.

   Design an inspection plan for a coastal bridge that assumes regular exposure to saltwater. Include technology you might use and methods for evaluating structural integrity.

   Hint

   Consider environmental factors that affect the structure.

6. 6.

   Evaluate the implications of failing to use thermal imaging in dam inspections. What could be the potential consequences?

   Hint

   Think about the long-term effects of missed maintenance.
