上海中小河流治理中护岸结构施工时的顺河围堰价格与现行定额体系中的定型围堰单价偏差太大,定额体系中的定型围堰单价明显高于实际施工单价,给工程前期工程投资控制带来高估风险,使护岸方案经济比选失去了可靠性。文章提出在设计阶段就对施工围堰进行具体设计,造价人员根据围堰设计断面,按围堰筑拆工序确定单价,从而组成围堰筑拆价格。例举具体工程实例。阐述围堰组价过程。通过这种方式形成的围堰综合单价更符合实际施工情况及费用。从而在设计阶段就能更有效和准确的控制和确定工程造价,使带顺河围堰的护岸断面的方案比选更具有准确性和经济可靠性。
The price of Shunhe Cofferdam during the construction of bank protection in middle and small rivers in Shanghai is too much deviation from the unit price of cofferdam in the current quota system. The unit price of cofferdam in fixed system is obviously higher than the actual construction unit price, Bring the risk of overestimation, and lose the reliability of economic comparison of bank protection programs. The paper puts forward that the concrete cofferdam should be designed at the design stage, the cost staff design the cofferdam according to the cofferdam, determine the unit price according to the cofferdam dismantlement and disassembly procedure, and thus make up the cofferdam demolition price. Give examples of specific projects. Describe the cofferdam group price process. The cofferdam integrated unit price formed in this way is more in line with the actual construction conditions and costs. Therefore, it is possible to control and determine the construction cost more effectively and accurately in the design stage, and make the scheme of revetment cross-river cofferdam more accurate and economic than the election.
