site- specific settlements during construction and post-construction phases, through the life of the structure. • Verification of the interface considerations between DC and COL applications, which should be based on the information described in the above two bullets. The above considerations are appropriate for major seismic Category I foundations. Alternative, more simplified, approaches are acceptable for the case of smaller structures if adequate justifications are provided. 3.8.5-14 Revision 4 – September 2013 In the case of adjacent structures connected by appurtenances (non-flexible commodities, such as piping and conduit), the staff reviews the design criteria for total settlement and for relative settlement between adjacent structures to ensure consistency with the criteria used in the design of the appurtenances. 5. Structural Acceptance Criteria. For the loading combinations referenced in the first paragraph of Subsection II.3 of this SRP section, the allowable limits that constitute the acceptance criteria are referenced in Subsection II.5 of SRP Section 3.8.1 for the containment foundation and in Subsection II.5 of SRP Section 3.8.4 for all other foundations. In addition, for the five other load combinations in Subsection II.3 of this SRP section, the factors of safety against overturning, sliding, and flotation are acceptable if found to be in accordance with the following: Minimum Factors of Safety For Combination Overturning Sliding Flotation A. ----------------------- 1.5 1.5 --- B. ----------------------- 1.5 1.5 --- C. ----------------------- 1.1 1.1 --- D. ----------------------- 1.1 1.1 --- E. ------------------------- --- 1.1 6. Materials, Quality Control, and Special Construction Techniques. For the containment foundation, Subsection II.6 of SRP Section 3.8.1 references the acceptance criteria for materials, quality control, and any special construction techniques. For all other seismic Category I foundations, the materials and quality
