Research on Dynamic Control Method of Engineering Cost Effect of Engineering Design Change
Abstract
This study addresses cost overruns caused by engineering design changes by enhancing the precision and timeliness of cost control.
Grounded in dynamic control theory and full-process cost management principles, it systematically examines how design changes impact
costs through engineering practice. A three-dimensional dynamic control framework is established, comprising pre-change valuation, coordinated control, and real-time correction, with detailed operational procedures for each phase. The research demonstrates that design changes affect costs through three mechanisms: direct cost adjustments, schedule modifications, and ripple effects, enabling proactive cost prediction, real-time control, and post-change correction. The conclusion highlights that this dynamic control method effectively locks in cost benchmarks,
strictly controls incremental costs, and prevents deviation accumulation, providing actionable guidance for cost management in engineering
design changes.
