Ques 5 Civil

The old concert hall was demolished because of fears that the foundation would be affected by the construction of the new metro line in the area. Modern technology for underground metro construction tried to mitigate the impact of pressurized air pockets created by the excavation of large amounts of soil. But even with these safeguards, it was feared that the soil below the concert hall would not be stable. From this, one can infer that

the foundations of old buildings create pressurized air pockets underground, which are difficult to handle during metro construction.

metro construction has to be done carefully considering its impact on the foundations of existing buildings.

old buildings in an area form an impossible hurdle to metro construction in that area.

pressurized air can be used to excavate large amounts of soil from underground areas.
