CPWD Delhi Schedule of Rates (Electrical) 2021 (popularly known as DSR 2021) is a comprehensive technical document issued by the Central Public Works Department of India that External Electrical Distribution : The rates are based
The rates in the DSR are generally exclusive of GST (Goods and Services Tax).
Unlike older schedules where basic rates were complicated by excise duties, VAT, and octroi, the DSR 2021 rates are structured to seamlessly integrate the framework, simplifying invoice processing and audit verifications. 4. How Rates are Analyzed: The Science Behind the DSR
| Item Description | Unit | DSR 2021 Rate (₹) | DSR 2016 Rate (₹) | % Change | |----------------|------|------------------|------------------|-----------| | 1.5 sq mm Cu wire (FR) in conduit | per 100 m | 1,850 | 1,520 | +21.7% | | 4 sq mm Cu wire (FR) in conduit | per 100 m | 4,200 | 3,450 | +21.7% | | LED batten 20W (120 lm/W) | each | 450 | 380 (for 18W) | +18.4% | | Ceiling fan (1200mm, BEE 5 star) | each | 1,850 | 1,600 | +15.6% | | Copper plate earthing (plate size 60x60x6mm) | set | 6,800 | 5,200 | +30.8% | | Laying XLPE cable (240 sq mm, 3.5 core) | per meter | 950 | 810 | +17.3% |
Understanding the cost index is critical for accurate billing and contract management. As rates change over time, CPWD applies a to adjust the base DSR rates to present market conditions.
While DSR is the gold standard, users must be aware of its limitations:
