I am trying to calculate the total cost for CSI 2004 Division 12 products on my project. The owner has purchased many pieces of furniture, furnishings and miscellaneous items. At this point, I'm not sure how practical it is for me to find everything the owner purchased to get an accurate material cost for this and the other MR credits. My initial thought is to make my best guess by including the big costs (workstations, files & storage, tables, chairs, task light--items associated with the workstation ) and guess how much smaller items, like some artwork and plants, collaboration seating and conference room furniture cost.

Also, is there some kind of rule of thumb “cut-off” date to use with Division 12 products? It seems like the owner continues to make purchases after construction is complete that would fit into Division 12.
