For a commercial job it's not actually by room. Imagine a building say 250' x 250'. And 80% of the area is retail space. And on the retail space you got different departments which requires different finishes for floor/ walls/ and sometimes ceilings. And top of that you also need to show the graphics that goes to the wall (sizes, types ,etc.). And say for wall finishes depending on the ceiling heights say 20', they might want tile from finish floor to 12' ,..and the remaining (up to ceiling) would just be paint.
Anyone there who worked on commercial projects (shopping malls, supermarkets, groceries, etc..). Any ideas you want to share on how you do your job?
Thanks
