• true

• false

He made the foundations for the other two legs much deeper so they too were founded on firm soils. This required _______ - excavation below the ground surface (6m below GWT).

As structures continued to become larger and heavier, engineers continued to learn more about foundation design and construction.

• true

• false

is the art and science of molding materials we do not fully understand into shapes we cannot precisely analyze to resist forces we cannot accurately predict, all in such a way that the society at large is given no reason to suspect the extent of our ignorance.
