This document discusses cost control methods used in construction projects. It begins by defining cost control as the process of measuring and collecting cost records and comparing actual progress to plans in order to maximize profit within a designated period while maintaining work quality. It then describes several cost control processes used including identifying cost-influencing factors, mitigation strategies, data collection, and providing recommendations to contractors. The objectives of materials management in cost control are to minimize costs, ensure quality materials are available when needed, reduce inventory levels, and efficiently purchase, handle, and store materials. Effective cost control requires timely responses to cost data in order to take corrective actions.
