【摘要】：近年来,随着社会用电量的不断增长,火电机组装机容量逐年增长,火电项目建设投资保持着较高的增速。由于火电项目建设周期长、投资大的特点,做好工程造价控制,提高项目经济性已成为火电项目工程管理中的重中之重。作为对项目投资的影响占比60%—70%的设计阶段,造价控制对整个项目的实施具有极大的作用。本研究首先对当前的设计阶段造价控制方法展开了分析。发现限额设计存在参考指标没有统一标准,不同地域、技术参数、系统配置无法与限额指标匹配的问题,价值工程在功能分析阶段较为复杂,功能评价主观性较强等问题。基于此,对限额设计方法进行优化,并采用AHP来优选系统方案,再结合设计合同管理与设计监理两大管理内容,构建起“四位一体”的控制模型:在设计开始之初,通过设计招标与设计竞赛相结合的方式确定设计单位,利用奖惩机制的设计费用管理,达到了以设计合同为依据的设计管理目的;随后,通过《火电工程限额设计参考造价指标》的应用,以对不同技术方案的项目进行模块调整后的限额指标作为造价控制的依据,对传统限额设计方法进行改进,提出了竖向控制与平行控制相结合的限额设计管理方式;在系统方案配置的问题上,提出可基于AHP进行方案优选方法;最后,通过采用设计监理,对设计工作进行全过程的跟踪管理,并引入相应激励机制,激发监理单位对造价控制的积极性,以提高设计质量,控制工程造价。本研究构建的“四位一体”控制模型,弥补了在火电项目设计阶段缺乏成型的控制模型的缺点。最后,通过将其应用在哈密电厂4×660MW机组新建工程的案例上,论证了此控制模型的有效性和可行性。
[Abstract]:In recent years, with the continuous growth of social electricity consumption, the installed capacity of thermal power units is increasing year by year, and the investment in thermal power project construction has maintained a high growth rate. Due to the long construction period and large investment of thermal power project, it has become the most important task in the project management to control the project cost and improve the project economy. As the design stage of 60%-70% of the project investment, the cost control plays a great role in the implementation of the whole project. In this study, the current design stage of cost control methods are analyzed. It is found that there are some problems in quota design, such as no uniform standard of reference index, different regions, technical parameters, system configuration unable to match quota index, complex value engineering in function analysis stage, strong subjectivity of function evaluation, and so on. Based on this, this paper optimizes the method of quota design, adopts AHP to optimize the system scheme, and combines the two management contents of design contract management and design supervision, and constructs a "four-in-one" control model: at the beginning of design, Through the combination of design bidding and design competition, the design unit is determined, and the design cost management based on the reward and punishment mechanism is used to achieve the purpose of design management based on the design contract. Through the application of reference cost Index for quota Design of Thermal Power Project, the quota index after module adjustment for different technical projects is taken as the basis of cost control, and the traditional quota design method is improved. This paper puts forward the management mode of quota design combining vertical control and parallel control, and puts forward the method of optimal scheme selection based on AHP on the problem of system scheme configuration. Finally, through the adoption of design supervision, In order to improve the design quality and control the project cost, the design work is followed and managed in the whole process, and the corresponding incentive mechanism is introduced to stimulate the enthusiasm of the supervision unit to the cost control. The "four-in-one" control model is constructed in this paper, which makes up for the shortage of the control model in the design phase of thermal power project. Finally, the validity and feasibility of the control model are demonstrated by applying it to the new project of 4 脳 660MW unit in Hami Power Plant.
