This document defines rate analysis in civil engineering projects as determining the rate of work like earthwork, concrete work, etc. It discusses factors that influence rates like material specifications, quantities, labor costs, transportation costs, and profit. Rate analysis is important to determine actual unit costs, economical use of materials, cost of extra work, and revising rates due to cost changes. The document provides examples of labor classification, lead statements to calculate material transportation costs, and defines lead and lift terms for earthwork.
