Abstract: In order to solve the shortcomings of the existing cost control methods for assembled building, such as the project cost is higher than expected and the cost control deviation is large, this paper proposes a cost control method for assembled buildings under digital technology. First, the construction cost data of assembled building are collected and preprocessed. Secondly, the data characteristics of the construction cost of assembled building are extracted, and the construction cost estimation model of assembled building is built using support vector mechanism. Finally, the kernel function is introduced to control the construction cost of assembled building. After verification, it was demonstrated that the application of this method for cost control resulted in an EV greater than AC, a cost performance index (CPI) value greater than 1, and a final cost control deviation of 260,000 yuan. Small deviation, effective cost control methods.

Keywords: digital technology; assembled building; SVM; support vector machine; RBF; radial basis function; cost control deviation.
