Description

This IStandardn provides a guideline for an engineering approach to the design and subsequent installation of pile foundations. The purpose is to furnish a rational basis for this process, taking into account published model building codes and general standards of practice. It covers such topics as: 1) Administrative requirements; 2) pile shaft strength requirements; 3) soil-pile interface strength requirements and capacity; 4) design loads; 5) design stresses; 6) construction and layout guidelines for pile design; and 7) installation guidelines for pile construction. In addition, the IStandardn includes information on applicable standards from ASTM, AWPA, and ACI. It concludes with an Appendix on partial factors of safety.
