Our GC requested that I post a clarifying question for him about the windows on our project--

If the Maker of the window components ships the window components to the Installer and the Installer assembles the components into actual window units in their shop, is the Installer the "Manufacturer" and the maker of the window components the "Raw Material Extraction Location"?

This follows the same logic as steel packages--where the local fabricator who customizes the semi-finished units for the specific project is the "Manufacturer," and the Mill that makes the semi-finished units from scrap and virgin ore is the "Raw Material Extraction Location."

Thanks very much for your thoughts.
