when evaluating loads induced by the construction process and by differential settlements, as described in items E and J above. Additional guidance to consider in the review of DC and COL applications is given below. i. In the case of a DC application, the staff reviews the following information: • Postulated set of soil stiffness parameters for the construction phase and the technical bases for its selection, for all soils within the zone of influence surrounding the structures. The zone of influence is defined as that region to the side and below the structure that may induce loads on the structure if induced settlements occur and/or loads are applied within the zone. • Postulated set of soil stiffness parameters for the post- construction phase and the technical basis for its selection. • Postulated construction sequence and corresponding set of construction loads and the technical basis for its selection. • Analysis methodology for computing soil settlements (total and differential, short term and long term), which should incorporate the postulated soil stiffness and construction sequence, and include potential long term settlement effects through the life of the structure. • Analysis methodology for computing member forces and moments induced by the settlements and construction sequence, which should then be taken as a separate construction sequence/soil 3.8.5-13 Revision 4 – September 2013 settlement load case, to be included in the structural design of the foundation and superstructure in addition to all other load cases. • Interface considerations between DC and COL applications (e.g., COL action items and appropriate acceptance criteria) that permit verification of the foundation design by a COL applicant. An acceptable interface consideration is to incorporate the settlement profiles computed for a postulated construction sequence (the various stages of construction and post construction), which a COL applicant can then use for verification
