BIM-based Optimization of Design and Construction for Bridge Projects

In order to improve the efficiency of design and construction for bridge works，BIM（Building Information Modeling）is proposed for application. Through the analysis of the characteristics of bridge works and relevant problems，the BIM-based solutions for design optimization and construction optimization are developed，including conceptual design optimization，detailed design optimization，the optimization of construction sequences，construction scheduling，and construction management. A practical case is also presented to demonstrate the feasibility and validity of the solutions. It is shown that BIM has the potential to improve the design and construction of bridge works. The research will benefit mega-complex bridge projects which adopt BIM to aid in design and construction in the future.
