BIM-based power transmission and transformation project whole-process dynamic cost management method

Abstract

The invention discloses a BIM-based power transmission and transformation project whole-process dynamic cost management method, which comprises the following steps: 1, creating a BIM standardized family library of a power transmission and transformation project in combination with the characteristics of the power transmission and transformation project and the measurement standard of a bill of quantities, and realizing rapid standardized modeling of the power transmission and transformation project; 2, designing a project amount calculation plug-in for the power transmission and transformationproject, and achieving the quick and automatic calculation of the construction cost of the power transmission and transformation project based on BIM; and 3, realizing information sharing among different project participants by developing a BIM-based power transmission and transformation project cost management system platform. According to the method, cost management of the whole life cycle of the power transmission and transformation project is realized; automatic measurement and calculation of the construction cost of each stage are realized, the integrity and authenticity of engineering data transmission are ensured, and the problems of disjunction and distortion of information transmission in the construction cost management process of the power transmission and transformation project are solved, so that the efficiency, accuracy, transparency and refinement level of construction cost management of the power transmission and transformation project are realized.

Description

technical field [0001] The invention relates to the field of power systems, and mainly relates to a BIM-based dynamic cost management method for the whole process of power transmission and transformation projects. Background technique [0002] Power transmission and transformation projects have the characteristics of complex construction conditions, large investment, long operation cycle, and large resource consumption. The cost management of the whole life cycle involves investment decision-making, design, bidding, construction, and completion acceptance. Multiple departments are responsible for the stage cost management, resulting in the independent existence of life cycle cost information of a project in each department system, lack of communication between departments, and poor data sharing, resulting in delicate life cycle cost management of power transmission and transformation projects level is not high. [0003] Cost management is the main task of cost management at...

However, under the traditional management system and working methods, problems in the implementation of such cost control methods are constantly highlighted: it is difficult to effectively obtain the planned cost and progress information of each node to carry out real-time engineering cost based on the earned value principle. Control; for quota design, it is difficult to decompose its design indicators reasonably, which leads to the passive implementation of quota design, a plan intended to actively control the cost, etc.

Therefore, such methods cannot effectively control the project cost in actual projects. There are still missing items in the bidding list, inaccurate calculation of engineering quant
