5D BIM Will Influence On The Current Construction Cost Management Mode

5D BIM is in the 3D building information model based on the integration "time information" and "cost information", formed by a 3D solid progress+1D Progress (time)+1D (cost) five-dimensional building information mode. It integrates project quantities, project schedule, project cost, It can not only statistical project quantities, but also link the 3D model and Work Breakdown Structure. To dynamically simulate the construction process of change, Real-time monitoring of the progress of construction implementation and construction costs. It is because of BIM and derived 5D BIM has so many advantages, Housing and Urban-Rural Development and local authorities have been issued notice that actively promote the implementation of BIM in construction projects, This is both an opportunity and a challenge, Since the emergence of BIM will require construction companies to make corresponding changes, Especially in the project cost management, and the cost management is One of the three management goals, namely Time, Quality and Cost. It is a key factor in evaluation of the project, it is also the focus of content to a Construction business. Therefore, the impact study of 5D BIM to project Dynamic cost management is necessary.The method of the this paper is to use the case study analyzes the intrinsic link between BIM technology used and the dynamic cost in Zhuhai Opera project, combined with functional analysis of 5D BIM, Predict 5D BIM will have a positive impact to current construction cost management, including Objective responsibility, business planning, cost analysis, cost planning, measurement engineering, ERP reported amount, on clear statements, data processing, coordination, and explains how to change the existing dynamic cost management.The study found that in the case of the use of 5D BIM technology, the dynamic cost management based on 5D BIM technology platform will appear a series of fine changes. To this end, we should focus on the construction of the future construction enterprises, we must start to take a variety of measures at this stage to learn and use 5D BIM technology.
