Application Study on Cost Management in BIM5D of Beijing-Xiong'an Intercity Railway Electrification Engineering
BIM5D technology is the development of BIM technology to the current stage of the latest way to achieve multidimensional expression,which is on the basis of the 3D visualization BIM3D,further forms to BIM4D by adding time information,and then develops into BIM5D by adding cost information.In the paper,a solution to the cost of output value was proposed by analyzing the current status of the application of BIM technology in cost management,and addressing the numerous problems in associating model components with cost information through existing WBS(work breakdown structure)in the current bill-of-quantity pricing mode of the railway electrification engineering.The BIM5D model was built through the three work processes of BIM model establishment of railway electrification engineering,summary statistics of project quantities,and correlation between the BIM model,schedule and cost.This paper mainly introduced the dynamic cost control process of railway electrification BIM5D system independently developed by China Railway 21st Bureau in the construction of communication projects.
