Single or double story-height vertical framing members are installed first by attaching to floor slabs or other lateral structural elements. After which, intermediate horizontal framing members are installed between the verticals and the process repeats itself as the installation progresses either horizontally around building or vertically up at some points during or after the framing member installation is complete, glass and other infill materials are installed including any decorative trims that may be.
