1. What are the concerns of project manager Bryan Lee?
Do buildings methods and materials match those in the agreement ?
Are schedueles met?
Are costs kept within bounds ?
2. Why do they engineers and construction workers use a boring machine to make tunnels instead of cut and cover construction?
Cause from looking 180 feet off the ground , it needs to go , piece by piece and assenbled on the excavation's floor.
3. What do the worker’s do to protect themselves in the newly formed tunnels from harmful levels of gases found in the soil at the various new subway sites?
Wear helments, and other good clothing that doesnt burn through, and good to keep yourself alive !!
