This study presents a systematic approach to cost control in largescal e industrial construction projects through information technology integration. The framework encompasses three core components: comprehensive information collection, variance analysis, and cost expenditure correction. By implementing standardized coding systems and automated data collection processes, the system enables real-time cost monitoring and deviation analysis. The research dmostrates how digital tools can transform traditional cost management practices, reducing manual errors and improving control efficiency. Through case analysis, the paper illustrates how this system effectively manages budget overruns through early detection and systematic correction measures, particularly in equiment procurement and construction phases.
