As mentioned get the designers details (hopefully they were included at plan review - if not then get plan review to change where all of the details are required). I typically performed many inspections for a curtain wall. Since it is often the weather barrier we look at so I inspect framing and support, insulation, sometime exterior gypsum (when it is a rated wall), vapor retarders, vapor barriers, sometimes installed masonry,electrical, glazing, interior finishes and interior final . I also inspect the wall to floor details if the structure has rated floor assemblies.
