n to transfer shear when waterproofing is used for a range of site conditions (soil sites with shear wave velocity of 1000 feet per second to hard rock). D. Adequacy of the definition of dead load for uplift evaluations (floatation and seismic overturning), including the treatment of the stored volume of water in any pools. E. Detailed explanation of how settlement is evaluated, including potential effects of static or dynamic differential settlement, dependence on time (i.e., short term vs. long term), effect of the soil type (i.e., granular vs. cohesive), and effect of the foundation type and size (e.g., basemats, spread footings). Evaluation of the effects of settlement on construction procedures. Evaluation of the allowable settlement (total and differential) that can be accommodated in the foundation/structures. F. The maximum toe pressure for basemat design under worst-case static and dynamic loads and its justification. G. The evaluation of stiff and soft spots in the foundation soil to maximize the bending moments used in the design of the mat foundation. H. Description of the design details of critical locations, such as the junction of sidewall and basemat and the junctions of basemat to sumps. I. Detail explanation of the load path from all superstructures to the mat foundation to the subgrade. Discussion of any unique design features that occur in the load path (e.g., any safety-related function that the tendon gallery may have as part of the foundation in a prestressed containment or the connection of any internal structures to a steel containment and its supporting foundation). J. Explanation of how loads attributable to construction are evaluated in the design. Some examples of items to be discussed include the excavation sequence and loads from the construction sequence of the mat foundation and walls, as well as the potential for loss of subgrade contact (e.g., because of loss of cement from a mud mat) that may lead to a differential pressure
