BIM project progress and cost management system based on earned value theory

Abstract

The invention discloses a BIM project progress and cost management system based on an earned value theory. The system comprises steps of establishing a BIM building model based on design paper and adding an environmental factor simulating a construction field; collecting construction activity information and associating the construction activity information with corresponding engineering information in the BIM building model; comparing and analyzing the engineering amount of current real complete part and the engineering amount of a planned complete part on the basis of the earned value theory and determining whether a project progress lags, and determining whether project cost exceeds planned cost by comparing generated cost with current budget amount. The BIM project progress and cost management system based on the earned value theory is used in building projects, may clear the project progress and cost control case, may feed back the project progress and cost control state in a visualized way by using the BIM building model, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of BIM project progress and cost management systems, in particular to a BIM project progress and cost management system based on the principle of earned value. Background technique [0002] The earned value principle uses cost indicators to represent the value of each project task, and reflects the influence of various factors such as time, resources, cost, and complexity of the project task. As a management method of modern project management, the earned value principle is a project It is an important means of schedule control and project cost control, and plays an important role in project schedule and cost management. [0003] However, in order to apply the earned value principle to construction projects, there are still several bottlenecks that need to be overcome: (1) The construction period of construction projects is long, and the amount of information involved is huge, including materials, personnel,...

[0003] However, in order to apply the earned value principle to construction projects, there are still several bottlenecks that need to be overcome: (1) The construction period of construction projects is long, and the amount of information involved is huge, including materials, personnel, production equipment, etc., and changes occur The opportunity is large, and it is difficult to establish a data platform that faithfully reflects the actual situation of the construction project; (2) The life cycle of the construction project includes the project planning stage, design stage, construction implementation stage, and operation and maintenance stage, and relevant dynamic changes need to be collected in time , in order to establish a reasonable engineering project data platform; (3) The principle of earned value requires a high-density data monitoring cycle, but in construction projects, high-density collection of engineering data is not only a huge workload, but also increases the cost of data management investment; based on the above reasons, there is an urgent need to improve the deficiencies of the above-mentioned existing earned value principle system applied to construction project management, so as to meet the needs of use
