INTEGRATING BRIDGE INFORMATION MODELING (BrIM) WITH COST ESTIMATION AT THE CONCEPTUAL DESIGN PHASE OF BRIDGES

摘要

Integration of bridge information modeling (BrIM) with bridge management systems and computer-aided engineering design solutions had inspired many researchers over the past few years. Several successful integrations of BrIM with these solutions had significantly leveraged downstream processes of bridge projects. Over the years, one of the major obstacles encountered by BrIM integration experts was the functional interoperability with other solutions. In this study, research objectives are intended to demonstrate the viability of integrating BrIM with cost estimation while resolving BrIM integration with computer-aided structural analysis solutions interoperability issues. In this paper, an integrated prototype that fosters operational efficiency and cost savings for multiple types of bridges is presented. The proposed research methodology includes a preliminary estimation system comprising cost optimization modules which is developed in a .NET framework. The developed prototype will be capable of receiving and automatically incorporating 3D real-time information reflecting site alterations and corresponding effects on project overall cost. A case project was defined to validate the model and illustrate its corresponding numerical capabilities. Results presented in this study will enhance estimation techniques for bridge contractors and stakeholders by the inclusion of all direct and indirect costs associated with the different phases of a bridge project ranging from design conceptual phases to substructure, including heavy earthmoving operations, and superstructure. The prototype model is anticipated to be of major significance to contractors and considered a "brand-new" contribution to BrIM integrated technologies with cost management approaches.
