If a specific item is not listed in the DSR (e.g., a specific brand of smart home automation system), it is treated as a "Non-Schedule Item."
Understanding the Analysis of Rates (AoR) is crucial for contractors. Unlike a simple market rate, CPWD calculates DSR rates using:

Analysis of Rates: The DSR includes detailed breakup (material quantity, labor hours) for major items, enabling transparency.
Revision Cycle: The 2021 edition supersedes previous versions (e.g., 2014, 2016). CPWD generally revises DSR every 2–3 years to reflect market price changes.
Applicability: While primarily for Delhi, many states and other central agencies (e.g., MES, Railways) adopt CPWD DSR with modifications.
Despite its comprehensiveness, contractors and consultants report the following issues:
