Content:
consolidation properties, water content, or potentially undesirable response to seismic or other events. E. Rock mass containing voids, karsts, and other discontinuities located or oriented such that instabilities or strength reduction in the foundation material may occur. F. History of deposition and erosion, including glacial and other preloading influence on soil deposits. G. Estimates of soil consolidation, consolidation parameters, such as preconsolidation pressures and coefficient of consolidation and methods used to estimate these values. 2. The static and dynamic engineering properties of soil and rock strata underlying the site (Subsection 2.5.4.2) as supported by representative field and laboratory test data provided by the applicant. 3. The relationship of the foundations of all seismic Category I and other safety-related facilities to the subsurface materials as illustrated on plot plans and profiles (Subsection 2.5.4.3) provided by the applicant. 4. The results of seismic site exploration for example refraction and reflection surveys, suspension logging, down -hole and cross-hole explorations, as presented in the applicant’s technical submittal by discussions, plot plans, boring logs, tables, and profiles to support the assumed dynamic soil or rock characteristics (Subsection 2.5.4.4) and stratigraphy. 2.5.4-3 Draft Revision 5 – August 2013 5. Safety-related excavation and backfill plans and engineered earthwork analysis and criteria (Subsection 2.5.4.5) as illustrated on plot plans and profiles, discussed in the text, and supported by explorations for borrow material, test fills and adequate representative laboratory test records. 6. Groundwater conditions and piezometric pressure in all critical strata (Subsection 2.5.4.6) as they affect the loading and stability, and durability of foundation materials. This part of the staff review also includes an evaluation of the applicant's plans for dewatering during construction as well as groundwater
