The subgrade beneath the footing is ripped, scarified, and recompacted in place to a minimum of ninety-five percent relative compaction, with a geotech note requiring confirmation of a minimum fifteen hundred pounds per square foot bearing capacity. Reinforcing includes number four bars at twelve inches on center each way in the slab, number five bars at sixteen inches on center transverse, and three number five longitudinal bars within the footing profile. A vapor barrier is reinstated around the perimeter, and a supporting connection detail references sheet S5.1.
