23.1.2. Challenges in underground construction

Try these first

1. 1.

   What are geotechnical uncertainties?

   Hint

   Think about what can happen if the soil behaves unexpectedly.

2. 2.

   Name a method used to improve ventilation in tunnels?

   Hint

   Consider how air is circulated in enclosed spaces.

3. 3.

   What do geotechnical uncertainties refer to?

   • Soil predictability
   • Soil variability
   • Soil moisture levels

   Hint

   Consider variations in soil during construction.

4. 4.

   True or False: Adequate ventilation is not important in underground construction.

   • True
   • False

   Hint

   Think about the air quality in enclosed spaces.

5. 5.

   How would you approach mitigating ventilation issues prior to beginning an underground construction project?

   Hint

   Consider the initial steps and how they relate to worker safety.

6. 6.

   Design a basic safety protocol for workers in a construction site with known geotechnical uncertainties.

   Hint

   Think about how to protect workers based on unknown conditions.
