Research on whole-cycle cost dynamic control and cost optimization strategies of housing maintenance and renovation projects
房屋维修改造项目全周期成本动态控制与造价优化策略研究

摘要

在我国城市更新与存量资产提质改造持续推进的背景下，房屋维修改造项目数量快速增长，项目呈现单体规模差异大、现场条件复杂、变更签证频发、成本管控难度高等特征。传统静态成本管理模式难以适配维修改造项目全生命周期的不确定性，易出现预算超支、效益偏低、资源配置不合理等问题。为提升项目经济性与管理精细化水平，本文以房屋维修改造项目为研究对象，基于全周期管理理论与动态成本控制思路，梳理项目各阶段成本构成与管控要点，采用文献研究法、案例分析法、动态跟踪法，识别当前成本控制核心痛点。研究构建全周期成本动态控制体系，提出针对性造价优化策略，结合实际案例验证其有效性，为同类项目提供理论参考与实践路径，推动项目从被动核算向主动管控转型。

Abstract

Against the background of the continuous promotion of urban renewal and quality improvement of stock assets in China, the number of housing maintenance and renovation projects is growing rapidly. These projects are characterized by large differences in single-unit scale, complex on-site conditions, frequent changes and visas, and high difficulty in cost control. The traditional static cost management model is difficult to adapt to the uncertainty of the whole life cycle of maintenance and renovation projects, which is prone to problems such as over-budget, low efficiency and unreasonable resource allocation. To improve the economic efficiency and refinement of project management, this paper takes housing maintenance and renovation projects as the research object, based on the whole-cycle management theory and dynamic cost control ideas, combs the cost composition and control points of each stage of the project, adopts literature research, case analysis and dynamic tracking methods to identify the core pain points of current cost control. The study constructs a dynamic cost control system covering the whole project cycle, puts forward targeted cost optimization strategies, verifies its effectiveness with actual cases, provides theoretical reference and practical path for similar projects, and promotes the transformation of projects from passive accounting to active control.
