【摘要】：近些年来城市污水处理厂的规模不断增大,同时污水处理工艺也越来越繁杂,这种趋势将直接增加城市污水处理工程设计、施工、运营、维护等阶段的管理难度。也对污水处理厂建设与运营各阶段的成本费用控制提出了新的要求。为了解决这些问题,首先需要我们从污水处理厂的建设投资控制着手,运用先进的建筑信息模型(BIM)技术控制建设投资,管理好从立项、设计、施工、运营、维护等各阶段成本投入,来克服建设投资和运营成本中预算超支问题。首先对污水处理厂建设与运营各阶段的投资和成本进行识别,找出影响投资和成本的因素。采用BIM技术对传统的项目建设管理模式进行流程再造,对各阶段提出实质性的控制手段,特别在设计阶段选取前期准备时间、设计实施时间、企业期望值、管理工作成本、运行实施成本、外部因素成本这6个因素作为评价因子,通过运用灰色关联法得出聘请专业化第三方BIM实施机构与设计单位管理人员共同组建成为项目BIM技术核心团队最优方案。最后对某城市H污水处理厂基于BIM技术的投资和成本控制进行了实例分析,包括项目建设投资评价、运营及效益评价以及综合评价。其中建设投资节约费用占总概算投资的16.3%和签约合同价格的17.9%,运营成本节省费用占可行性研究报告的26.6%。论文建立了评价指标体系,各评价内容又包含目标、影响、过程以及效益评价等,通过模糊综合评价法对数据进行了计算分析,最后计算出本城市污水处理项目综合评价成绩为优等级92.5分,证明通过运用BIM技术实现了对项目建设投资和运营成本控制的预期目标。
[Abstract]:In recent years, the scale of city sewage disposal plant is increasing, while the sewage treatment process is more complicated, this trend will directly increase the city sewage treatment engineering design, construction, operation, maintenance and other stage management difficulty. Also put forward new requirements for the cost of the sewage treatment plant construction and operation of each stage in order to control. To solve these problems, we first need to proceed from the sewage treatment plant construction investment control, the use of advanced building information model (BIM) technology to control the construction investment, management from the project, design, construction, operation, maintenance and other costs in each stage of investment, to overcome the problems of budget construction investment and operating costs. The first identification the sewage treatment plant construction and operation of each stage of the investment and cost, find out the influence factors of investment and cost. Using BIM technology to the traditional project management mode of construction process The control means of reengineering, substantive of each stage, special selection of preparation time in the design phase, design implementation time, business expectations, management cost, operation cost, the cost of these 6 factors external factors as evaluation factors, by using the grey correlation method to employ specialized third party mechanism design and implementation of BIM unit managers jointly set up to be the core technology of BIM project team optimal scheme. At the end of a city sewage treatment plant H BIM technology based on investment and cost control are analyzed, including the project construction investment evaluation, evaluation and operation efficiency and comprehensive evaluation. The construction investment cost savings accounts for the total investment budget of 16.3% and signed the contract price 17.9%, operational cost savings costs account for the feasibility study report of the 26.6%. this paper established the evaluation index system, the evaluation content and target , effect, process and benefit evaluation, through fuzzy comprehensive evaluation method to analyze the data, and finally calculate the city sewage treatment project comprehensive evaluation score of grade 92.5, that through the use of BIM technology to realize the project construction investment and operation targets of this control.
