The Schedule of Rates (SOR) is an official document published by government public works departments (such as CPWD) containing the unit rates of labor and materials. These documents are generally revised and republished every 3 years to account for inflation, market fluctuations, and changing construction technologies.

TotalCost=тИС(Quantity├ЧRate) тАФ Estimation principle relying on accurate SOR data
The revision cycle is determined by the necessity to maintain economic accuracy in public tenders. By updating the SOR every 3 years, departments ensure that the 'Estimated Cost' of projects remains realistic and close to the actual market price, preventing significant cost overruns or tender failures due to outdated pricing.
SOR serves as the primary reference for preparing Detailed Estimates.
It contains standardized rates for basic items like cement, steel, labor, and transport.
Cost Index is often applied to the base rates to adjust for regional variations during the 3-year period.
Published by the Central Public Works Department (CPWD) for central projects.
Uniformity in cost estimation across different projects.
Simplified tendering process as rates are pre-approved.
Fixed for 3 years, making it susceptible to sudden market inflation.
Requires constant monitoring via 'Cost Index' updates.
Government construction contracts.
Budget preparation for infrastructure projects.
Rate analysis for extra items in contracts.
While 3 years is the standard for major publications, individual departments may issue 'Market Rate Addendums' if prices fluctuate beyond a certain percentage threshold.
Option A (1 year) is sometimes used for specific local sub-schedules, but the formal SOR is defined for 3 years.
C is correct тАФ The Schedule of Rates is typically revised and published on a 3-year cycle to align project estimations with current market trends.
Always remember that in CPWD norms, if the market rate varies significantly during the 3-year block, a 'Cost Index' is used as a multiplier to adjust the SOR values.
