Implementing Earned Value Management using Bridge Information Modeling

摘要

Building Information Modeling (BIM) has widely become an effective tool in engineering and construction fields. It could be used in: generating shop drawings; detecting clashes; estimating quantities; and controlling documents. Applying BIM technology on bridges is named Bridge Information Modeling (BrIM). Bridge Information Modeling (BrIM) is an intelligent representation of bridges since it contains all information needed about bridges through their whole lifecycle. This paper presents the use of Building Information Modeling in cost and time management of infrastructure bridges. BIM-based cost estimation application is presented which is capable to carry out approximate cost estimate; and detailed cost estimate. The application is designed in a flexible manner to be used with default values, or user defined values. Different performance measurement indexes are used in order to control the cost and schedule during execution phase of construction projects. This application integrates BIM with Earned Value (EV) concept to determine the project status at specific reporting date. A case study is presented to demonstrate the use of the developed modules.
