SEGA Engineers has provided structural engineering including lateral loads analysis,
shear wall design, and framing calculations for the subject project. We have been asked
to comment on the applicability of detail 11/S20 for use at the front entry where the
approach will be a cast concrete stair over fill. The distance from top -of -slab to top -of-
stem wall is about 48 inches which is less than the specified 60 inch maximum. The
material at finish grade, be it purely soil fill or concrete over fill, is not particularly
relevant in this application. Note that the interior fill and slab on grade must be in place
prior to placing the exterior fill and stair.
Please address any questions to SEGA Engineers.
