While DSR is the gold standard, users must be aware of its limitations:
Post-2020, CPWD incorporated green building norms (GRIHA, IGBC). Notable new inclusions:
These items were missing in DSR 2019 and earlier, forcing contractors to rely on “provisional sums”.
A: Yes. Many private firms use CPWD rates as a benchmark for negotiation, but they typically add a premium for faster execution and premium brands.
Since 2021, CPWD has issued corrigenda for specific material price swings:
| Corrigendum No. | Date | Impact on Electrical | |---------------------|----------|--------------------------| | 01/2022 | April 2022 | Copper cable rates increased by 12% | | 03/2022 | August 2022 | LED rates revised downward (-8%) | | 02/2023 | March 2023 | Steel conduit rates increased due to raw material inflation. |
These are available on cpwd.gov.in under “Publications → Schedule of Rates → Corrigenda DSR 2021.”
Pro tip: Always check the latest corrigendum before submitting a bill or tender, or your rates may be considered outdated.
By mid-2023, copper and aluminum prices had risen over 35% from 2021 levels. Contractors executing fixed-rate DSR 2021-based tenders began incurring losses. Unlike civil works, electrical DSR does not have an automatic fuel or metal price index adjustment clause in standard works contracts (except for cost-plus contracts).
A comparison of key items from 2019 to 2021 shows significant jumps, primarily due to copper prices (up 40% from 2019 to mid-2021) and labor CEA (Chief Engineer’s Allowance) revision.
| Item | DSR 2019 (₹) | DSR 2021 (₹) | % Increase | |------|--------------|--------------|-------------| | 1.5 sq mm FR PVC copper wire per 100 m | 1,250 | 1,890 | 51.2% | | 2x2.5 sq mm flat FRLS cable per m | 42 | 58 | 38.1% | | 20 mm PVC conduit (ISI marked) per m | 17 | 24 | 41.2% | | Single pole MCB 6A (10 kA) | 205 | 310 | 51.2% | | 1200 mm LED batten (20W) | 420 | 560 | 33.3% | | Pipe earthing – complete (3 m depth) | 3,200 | 4,750 | 48.4% | | Manpower – Electrician (per day) | 550 | 720 | 30.9% |
Observation: The highest hikes are in copper-based items (wires, cables) and modular switches (imported components). PVC conduit rates rose due to crude oil price volatility.
