砂质海岸海滩养护工程造价概算控制技术探讨——以珠海市桂山岛海豚湾海滩养护工程为例

Discussion on Cost Control Technology of Sand Coast Beach Restoration Project——A Case Study on Dolphin Bay,Guishan Island,Zhuhai

砂质海岸海滩在全国沿海各地都有分布,其养护工程是海岸生态修复工程的主要类型之一。砂质海岸海滩养护工程造价概算是海滩养护工程管理决策的重要依据,对海滩养护工程高质量实施具有重要意义。文章针对我国砂质海岸海滩养护工程造价概算控制的技术需求,在分析砂质海岸海滩养护工程造价构成的基础上,探讨了海滩养护工程造价概算技术流程,分析了海滩养护工程造价概算控制技术要点,并以珠海市桂山岛海豚湾海滩养护工程为例,测算了海豚湾海滩养护工程施工量及物料耗用量,调研了主要耗用物料的市场价格,编制了海豚湾海滩养护工程造价概算控制表,剖析了海豚湾海滩养护工程造价概算控制技术要点,以期为海滩养护工程造价控制提供技术方法。

The sand coast beach restoration project is one of important type for coast ecological restoration,and it is widely distributes along the coast of China.The cost estimation of sand beach restoration projects is an important basis for management decision-making of sand beach restoration projects,and is of great significance for high-quality implementation of sand beach restoration projects.Aimed to give some advises for cost control of sandy beach restoration project,this paper issued cost control process of the beach restoration project and analyzed control points of cost estimate for beach restoration project based on analysis of cost control types classification and cost composition of beach restoration project.Then the Dolphin Bay beach restoration project in Guishan island,Zhuhai was chose as a study case,We calculated the construction volume and material consumption of the Dolphin Bay sand beach restoration project,investigated the market prices of the main consumables,and prepared a cost estimate control table for the Dolphin Bay sand beach restoration project.Then the cost estimation methods and control points for beach restoration project were analyzed with study case.It is expected to explore technical methods for cost control of beach restoration projects.
