A thorough geotechnical investigation will usually suggest the ideal type of foundation
to be used at a site. This implies

final report will suggest the best two alternatives.
Typically, a structure is primarily designed for

the opposite to that criterion. After the criterion of functionality is satisfied, then the
two subsequent criterions considered by the designer are its
. Finally, after all these are satisfied, foundations are accommodated
around the above constraints. Rarely are foundations considered at the outset.

Exceptions are in seismic severe areas, and in predominantly civil works, such as earth
dams, deep excavations, tunnels, bridges, etc.
The influence of foundations has existed since prehistoric times, and become notable in
Chaldean and Egyptian public works. In contrast, most Greek monuments, so
influential to modern architecture, ignored the fine foundation experience developed by
older builders, primarily because the Greeks benefited from their peninsula's excellent
surface rocks. Even with an excellent rock subgrade, most Greek structures have
collapsed compared to the still existing Roman bridges, aqueducts and buildings.
