1. After analysis no output results are required to give to Site Engineer.
2. We are required to give Good For Construction (GFC) Drawings to site Engineer.
3. Yes we have to manually make the design of stairs, slabs, footings etc. ( Softwareare available for design of foundation and slab design ( SAFE))
4. Not only Bending moment but other internal forces like shear and torsion we need to check. Also serviceability limits such as crack width deflection etc we need to check. So we have to see each beam separately. After that if grouping is possible then we can do the grouping and according can make the structural drawings. Same is applicable for other structural members also.
