Analysis of the factors and control methods of project cost overruns
工程项目成本超支的影响因素与控制方法分析

摘要

工程项目在建设过程中常因前期估算偏差、进度协调不足、资源投入失衡以及外部条件波动而产生成本超支现象，进而影响项目质量与资金使用效率。围绕成本偏差的成因，可从管理链条的衔接度、信息传递的实时性及风险识别的深度观察其内在关联。若缺乏对施工过程、材料采购与人员配置的动态监控，成本累积将呈隐性扩散趋势。针对这些特征，通过建立清晰的成本责任分布、强化过程数据的跟踪机制并提升风险预警精度，可在项目推进中促成偏差的及时暴露与纠正，使资源投放与阶段目标保持一致性，从而提升整体成本控制水平。

Abstract

Construction projects frequently encounter cost overruns during implementation due to initial estimation inaccuracies, inadequate schedule coordination, imbalanced resource allocation, and external condition fluctuations, which ultimately compromise project quality and capital utilization efficiency. The root causes of cost deviations can be analyzed through three interconnected dimensions: management chain integration, real-time information transmission, and in-depth risk identification. Without dynamic monitoring of construction processes, material procurement, and workforce allocation, cost accumulation tends to spread covertly. To address these challenges, establishing clear cost accountability frameworks, enhancing process data tracking mechanisms, and improving risk early-warning precision can facilitate timely deviation detection and correction during project execution. This ensures resource deployment aligns with phased objectives, thereby elevating overall cost control effectiveness.
