QFL is correct. If the base of your structure is not on stable ground, then it will not be stable and likely fall down.
Many, many examples exist. Homes and buildings built in karst (limestone bedrock) areas have fallen into sinkholes. Over abandoned underground mines have collapsed when the mine collapses. Faults that may move during an earthquake. Massive water withdrawal from underground aquifers can cause the aquifer to collapse because it has lost the support it had when full of water.
Geo-hazards are everywhere and can cause lots of havoc.
Read below about the most recent landslide near Pittsburgh. A developer constructed a pad for a Wal-Mart out of fill on incompetent bedrock and unstable hillside. Inadequate or poor engineering led to the entire thing collapsing and sliding down over a four lane road and three rail rail line. And its still moving....
Follow Wikipedia for other geo-hazards.

Levees, bridges, highways, skyscrapers--all geared up on some thing. A civil engineer might decide to nicely known the intensity to basement rock, the region of energetic faults in the venture's footprint, and modifications in composition, or physique of concepts of rock basement, inherent weaknesses linked with joints, etc. the character of the beginning place under a civil shape could have an substantial pertaining to the way it would be designed, or maybe its placement.

Well, faults, slopes, and mass movements (landslides) dictate many of the minimum building standards that civil eng will have to go by.

Of course they are very important.
You cannot construct a project without knowing what is underground.
