Preliminary Using CPWD DSR 2021 (Civil) item rates as published, this worked scenario adds up to ₹1,522.95 (items 22.7.1). The item rates are CPWD's Delhi base rates; the quantities and the item mix are NirmanDost's scenario, not a CPWD bundle — adjust both to your site and apply your local cost index.
