What's the CPWD DSR rate for 20mm cement plaster on walls, per sqm?
A thicker 20mm cement plaster, cement mortar 1:4, coarse sand — CPWD doesn't literally label this 'external', but the coarse-sand plaster series is the one typically specified for brick-faced or exterior elevation work, where a thicker coat and coarser key are wanted.
Preliminary Using CPWD DSR 2021 (Civil) item rates as published, this worked scenario adds up to ₹421.40 (items 13.6.1). 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.

Notes
- Confirm the internal/external use case against your drawing spec — DSR's own text distinguishes plaster by sand type and thickness, not by internal/external labelling.
- Rates shown are CPWD Delhi base rates from CPWD DSR 2021 (Civil), as published (our extract of the book is dated 2025) — apply your local market / cost-index variation.
- CPWD has published later editions since (its site lists DSR 2023); the 2021 figures here are reference rates, not the schedule in force for a current tender.
- The item mix and quantities on this page are a NirmanDost worked scenario; the rates, units and descriptions in each row are CPWD's, verbatim. Every code opens in CivicMate for the source row.
