Above is the upper stair stringers, with triangles attached to receive stair pans.	Here the pans have been set in place.
This is the area for both sets of stairs. The upper stairs fit in at the furthest point, coming from the upper deck to the retaining wall, which is the edge of the pool area. the lower stairs are closest, and come off the wall, then execute a 45 degree, and drop at slope, roughly, forming a compound angle. They then run parallel to the concrete out onto the grassy area in the foreground and execute a 90 degree right. there are three sonotube concrete pillars that will support stairs out at the grass, and the last stair pan will be floating over the concrete in front of the column in the foreground.	This is a view of the deck underside. there are two columns and a beam in the foreground, with a 4 inch tall flashing forming an edge, wrapped all the way around the beam, and then to the house. In the background are two columns, with a channel on top, which is bolted to the face of the existing concrete deck. In between the channel and the wide flange beam run mud decking, which is highly corrugated sheet metal, used for roof and deck pours. Underneath that, running from channel to beam are 2 by 8 purlins at sixteen inch intervals, and three 2 by 4 studs running perpendicular, to bear the weight of the new concrete, which is 4 inches deep at the new pour. At the right, connected from the back channel to the front beam is another channel bolted all together. This both supports the edge of the new pour, and bears the upper end of the upper stair.
