Application Of BIM For Life-Cycle Cost Analysis Of Bridge: Case Study

BIM has been successfully adopted in the building construction industry worldwide. However, its potential for infrastructure remains largely underutilized due to several factors. In transportation infrastructure management, BIM can provide further benefits by integrating multiple elements such as scope, schedule, budget, maintenance records, project specifications, warranty information, purchase orders, existing service documentation, and MEP models into a 3D model. The present study involves work on use of BIM for performing life-cycle cost analysis of bridge which demonstrates the use of BIM for an infrastructure project. The use of BIM in different stages of design varies as per the requirement and due to this reason, it becomes mandatory to implement BIM suitably. The work consists of modelling of a bridge constructed in Pune district in the state of Maharashtra to perform life-cycle cost analysis. It involves developing 3D, 4D and 5D models of the designated bridge and then further estimate the entire cost including the maintenance and repair cost using life-cycle cost analysis method throughout its life span. Conceptual 3D, 4D and 5D models developed gives clear idea regarding scope, schedule and estimated cost for construction of the bridge. Further, life-cycle cost analysis gives a more detailed estimation of cost which includes maintenance and repair cost of the infrastructural project. It can be observed that this analysis can help the personnel involved in designing, planning, scheduling and execution to work more efficiently and cost effectively giving a broader idea about the financial aspect of the bridge to all its stakeholders.
