The Senior Cost Controller will review the Schedule of Rates (SOR), validate unit-rate applications against installed quantities and approved scope, and ensure labor, material, equipment, and subcontract costs are captured consistently at the applicable SOR line-item and work-package level. Establish and maintain man-hour budgets using SOR quantities, unit-rate labor assumptions, crew composition, productivity factors, and approved execution plans; compare budgeted, earned, actual, and forecast man-hours at tool level.
