Abstract: In response to the problem of limited selection of dimensions for cost element indicators in construction projects, which leads to unsatisfactory control effects, a precise cost intelligent control technology for construction projects based on time series models is proposed. Firstly, based on the characteristics of the construction project, the cost index of the project is predicted     by constructing a time series. Then select cost element indicators from four dimensions and calculate the cost index for each indicator. Finally, combined with edge computing technology, by optimizing the path of edge nodes, an intelligent cost control network model is constructed to achieve accurate intelligent cost control of construction projects. In the experiment, the effectiveness of the proposed intelligent cost control technology for construction projects was tested. The final test results indicate that the proposed cost intelligent control technology has a high evaluation value, and the intelligent control effect is relatively ideal.
