Advances in Constructional Engineering

The application of prefabricated buildings under the EPC (Engineering Procurement Construction) mode has gradually increased, but the problem of cost overrun still plagues project management. To solve this issue, this paper proposes an early warning model for cost overrun in prefabricated building projects. By analyzing the cost composition of prefabricated building projects, the main factors influencing cost fluctuations are identified. Using data mining technology, a cost prediction and early warning model based on historical data is established. Through real-time monitoring of project cost dynamics, potential overrun risks can be identified in a timely manner, avoiding the lag in cost control inherent in traditional project management. This model can effectively reduce the risk of cost overrun in prefabricated building projects and improve the economic benefits and management efficiency of projects.
