If you haven’t given it a look, you should check out PlanGrid! It is fantastic for punch lists and site analysis.
Otherwise it looks like you have the other areas covered. One question. If your Large Architecture brethren are using Revit you might want to consider Vectorworks 2015 as it can interpret and export files for use in Revit and do all the other things that Map + Civil 3d (less the stormwater calcs) + Sktechup + Land F/X do in one package at a considerable savings to buying all of those together.
