Identification of Engineering Cost Risk Factors and Phase-Based Control Strategies in Construction Projects
建筑工程项目中工程造价风险因素识别及阶段性控制策略

摘要

工程造价波动与风险失控是制约建筑项目投资效益提升的关键难题，各类风险伴随工程建设全过程呈现显著的阶 段性特征。为实现造价风险精细化治理，本文依托工程全生命周期理论，按照建设流程划分决策、设计、招投标、施 工、竣工结算五个阶段，系统甄别各环节造价风险要素，深入剖析风险形成机理与跨阶段传导特征。结合现场管控痛 点搭建分阶段、闭环式造价管控体系，提出适配各建设环节的落地性优化策略。研究旨在破解传统造价管控粗放、滞 后的问题，可为同类建筑项目成本风险治理与全过程造价管理提供参考借鉴。 

Abstract

Fluctuations in engineering cost and loss of risk control are key problems that restrict the improvement of investment benefits in construction projects. Various risks run through the whole process of project construction and show obvious phase-based characteristics. To achieve refined governance of cost risks, this paper draws on the theory of the whole project life cycle and divides the construction process into five stages: decision-making, design, bidding, construction, and completion settlement. It systematically identifies cost risk factors in each stage and deeply analyzes the formation mechanism of risks and their cross-stage transmission characteristics. In response to on-site management difficulties, a phase-based and closed-loop cost control system is established, and practical optimization strategies adapted to each construction stage are proposed. The study aims to address the extensive and lagging nature of traditional cost control, and may provide reference for cost risk governance and whole-process cost management in similar construction projects.
