About Rate Analysis Rate Analysis, Civil Engineering, AOR, SOR, DAR, Labour Output Constants, Construction Estimation, Costing, Billing, Material Cost, Machinery Cost, Afroz Civil Rate Analysis in civil engineering is a complete scientific method used to calculate the actual unit cost of construction activities. A proper rate analysis includes the breakdown of material, labour, machinery, overheads, contractor profit, taxes , and productivity norms. Accurate rate analysis ensures transparent billing , precise estimation , cost control , and efficient project management . It forms the foundation of the Analysis of Rates (AOR) and aligns with the Schedule of Rates (SOR/DAR) published by CPWD, PWD and State Engineering Departments. These codes help engineers maintain standard, uniform and technically correct cost calculations across all construction activities. Abbreviations Used in Rate Analysis: In this article, several important engineering abbreviations have been used, an...
