大型土石方工程造价控制主要风险点的分析与研究

The analysis and research on the main risk points of large earthwork project cost control are analyzed and studied

大型土石方工程是一类被认为投资大但施工工艺比较简单的工程,因而相对于主体工程复杂的建设管理程序而言,大型土石方工程的建设管理过程显得相对粗犷。实际工作过程中,由于建设项目前期工作不到位,建设项目的详勘工作滞后于初步设计文件,所以因地质条件不明引起工程造价大幅度变更的案例不计其数。同时,设计院作为概算编制单位,缺乏施工现场实际管理经验,在初设文本中编制的施工组织方案脱离工程实际,造成结算造价严重超概的现象也不胜枚举。文章通过对典型工程单独机械土石方场地平整工程的概算编制、复核对比分析,得出大型土石方项目概算编制(复核)的要点,并找出影响大型土石方工程造价的主要风险点,为相关单位在该方面的工作提供参考。

Large cubic metro project is a kind of investment is considered large but the engineering construction craft is simple, and relative to the complex of the principal part of the project construction management program, large cubic metro of earth and engineer ng for the construction of the management process is relatively straightforward. In the actual work process,Due to the project con struction preparation does not reach the designated position, construction project detailed survey work shall be lagging behind of the preliminary design documents, so the design institute as a unit for ten project dering cost greatly changes caused by geological conditions of unknown cases.At the same time ack of management experience, the construction site in the first set text compiling the con struction organization plan from engineering practice, the cost seriously ultra budgetary phenomenon also abound. This article through to the typical engineering mechanical conditions site formation works alone, check for tendering of comparative analysis, it is conclud ed that large cubic metro of earth and project for tendering （review）, the main points of the and find out the main risks affecting large cubic metro of earth and the project cost, provide a reference for relevant units in the aspects of the work.
