Target Cost Prediction for Highway Construction Projects Based on Stacking Modeling

Target cost is an expected cost objective set by the project management team during the project initiation phase. By setting the target cost, the team can carry out cost control and monitoring in the process of project execution to ensure that the actual cost of the project is in line with the expected target. This paper addresses the problems of target cost prediction for highway construction projects and proposes a method of project target cost estimation using the Stacking model to effectively overcome the deficiencies in target cost estimation. The Stacking model, as a comprehensive machine learning method in the process of determining the target cost of planning and designing projects, is able to reduce the human bias and make the results of the calculation of the target cost more scientific and effective, thus further improving the accuracy of cost management.
