大型桥梁成本控制与全寿命周期成本分析

工程成本控制的目标是合理地确定成本并进行有效的控制,以提高投资效益。桥梁全寿命周期成本包括整个寿命期内用于桥梁规划、研究、设计、试验、施工、养护、检测、维修、管理、拆除处理等支付的费用。我国现阶段工程成本管理只注重施工过程中的成本控制,忽视投资决策阶段、设计阶段的成本控制,成本管理的各阶段相互脱节,资料收集整理制度不完善。企业缺乏有效的成本管理体制。建议采用BOT(build-operate-transfer)模式,使企业主动按照全寿命周期成本进行管理和控制。以港珠澳大桥全寿命周期成本分析为例,说明:营运期成本在大型桥梁工程全寿命周期成本中所占比重较大,建议在桥梁投资决策和方案设计中,综合考虑桥梁全寿命周期成本。

Cost Control and Life Cycle Cost Analysis of Major Bridge

The aim of engineering cost control is to rationally determine and effectively control the cost so that the investment benefit can be significantly enhanced.The life cycle cost of a bridge covers the cost for bridge planning,research,design,testing,construction,maintenance,inspection,rehabilitation,management and demolishing within the whole life period of the bridge.In the present engineering cost management in China,the cost control in the construction process is always stressed while the cost control at ...
