What is Foundation Engineering?

Foundation Engineering is the art and science ofmolding materials we do not fully understand intoshapes we can not precisely analyze to resistforces we can not accurately predict, all in such away that the society at large is given no reason to

suspect o our ignorance.

Deep foundations can be as short as 15 to 20 ft or as long as200 ft or more and ma consist of driven iles drilled shafts

or stone columns.

A single drilled shaft often has greater load bearing capacityan a s ng e p e.

Deep foundations may be designed to carry superstructureloads throu h oor soil loose sands soft cla s andcollapsible materials) into competent bearing materials.

Even when piles or drilled shafts are carried into competent,

soils are located below the tip of these deep foundations.Dee foundation su ort is usuall more economical fordepths less than 100 ft than mat foundations.
