With the rapid development of urban metro construction

the cost management and risk control of metro deep foundation pit support projects have become increasingly crucial. This study focuses on metro deep foundation pit support projects based on BIM 5D technology

aiming to achieve dynamic integration of cost information and risk early warning. By constructing a BIM 5D platform that includes a 3D model

time schedule

and cost information

the data of the entire construction process of the metro deep foundation pit support are integrated

realizing the real-time update and dynamic integration of cost information. At the same time

using data analysis and model simulation functions

potential risk factors are mined

a risk early warning index system is established

and risk early warning signals are issued in a timely manner

providing strong support for project decision-making and improving the cost management level and risk response ability of metro deep foundation pit support projects.
