Even though CPWD may have released newer editions (like the 2022 or 2023 schedules), the remains a foundational document. Many large-scale government projects initiated in or around 2021-22 may still be billed on this DSR basis. Additionally, the DAR for the 2021 schedule continues to be a valuable tool for rate analysis.
The rates are pegged to market behaviors conforming to the Bureau of Indian Standards (BIS) and strict CPWD engineering specifications. DSR-2021 -Vol-1.pdf
A defining feature of the 2021 revision is the official phasing out of obsolete materials and the inclusion of green, energy-efficient engineering tech in line with Bureau of Energy Efficiency (BEE) guidelines.

The 2021 schedule is systematically divided into distinct chapters to cover the entire spectrum of electrical engineering works. Each chapter includes comprehensive sub-items detailing materials, sizes, capacities, and specifications. 1. Internal Wiring
While primarily for Delhi, many states and other central agencies (e.g., MES, Railways) adopt CPWD DSR with modifications.

Because the DSR is a baseline standard for Delhi, it requires localized adjustments when utilized in other regions across India. The CPWD periodically releases regional , which are percentages used to adjust the basic rates based on the local cost of transportation, labor, and material availability.
