Scrapping schedule

Hi accounting gurus

I’ll be commencing a renovation shortly, and am aware that I can claim for scrapping materials which will be disposed of in this process.

I have a depreciation report prepared by a registered QS, and just wondering, can I use values off here for scrapping values, or is this an independent report? Can someone point me in the right direction for finding info on what claims I can make for scrapped items?

Thanks in advance

Emma
