桥梁维修加固工程决策与设计阶段造价控制

Cost Control in Decision-making and Design Stages of Bridge Maintenance and Reinforcement Projects

摘要:

随着我国基础设施从大规模建设向建养并重阶段深刻转型，桥梁维修加固已成为保障路网安全、延长结构使用寿命、提升服务效能的核心任务。桥梁维修加固工程应强化前期决策与设计阶段的造价控制，开展检测评估、多方案技术经济比选研究，并构建动态造价控制体系。前期决策与设计阶段是造价管理的关键，可实现技术性能与经济合理性的统一。据此提出加强源头管控、深化方案比选、推行全周期动态管理等建议，为提升桥梁维修加固工程投资效益与造价精细化管理水平提供参考。

Abstract:

In China, as the infrastructure undergoes a profound transformation from large-scale construction to a stage that emphasizes both construction and maintenance, the bridge repair and reinforcement have become a core task in ensuring road network safety, extending structural service life and improving service efficiency. The cost control for bridge repair and reinforcement projects should be strengthened during the preliminary decision-making and design stages. Research is conducted on inspection assessment, and techno-economic comparison of multiple schemes. And a dynamic cost control system is established. The preliminary decision-making and design stages are identified as critical to cost management, enabling the integration of technical performance and economic rationality. Accordingly, the suggestions are proposed to enhance the source control, deepen the scheme comparison, and promote the full-cycle dynamic management, which provides references for improving the investment efficiency and refined cost management of bridge repair and reinforcement projects.
