Research on the Whole Process Visualization Management of Engineering Projects Based on Digital Twin Technology

Abstract

Large-scale construction projects with large scale, complex intersection of processes, fragmentation of information, labor shortage and other issues have challenged the traditional project management methods, and the demand for project visualization management is very urgent. This paper constructs a whole-process visualization management model of engineering projects based on digital twin technology, combines the earned value principle of cost dynamic correction with BIM technology, and proposes a method for controlling engineering construction cost. Finally, the method is applied to the construction cost analysis and Monte Carlo simulation experiment of a cross-sea bridge. Through the calculation of earned value parameters and the dynamic cost analysis based on the S-curve, it is found that when the construction of the project proceeds to the end of October 2022, the difference between the actual cost of the completed work and the planned cost of the completed work is 1,626,200 yuan. It shows that the project is characterized by cost overruns, slow progress and low efficiency. It can be concluded that the method of this paper has good applicability in the whole process visualization management of engineering projects.
