Abstract:To date, BIM (Building Information Modeling) is not widely utilized in infrastructure asset management.
Benefits achieved through implementation in vertical construction, however, suggest that BIM represents
significant opportunity for gains in process, material, and economic efficiency throughout infrastructure
life cycles. This research documents the current state of BIM implementation across four (4) regional
transportation authorities in the United States. Next, it provides a detailed case study analyzing and
comparing two current (2013) bridge projects, one that uses BIM and one that does not. The advantages
of BIM are confirmed through observed reduction in requests for information (RFIs) and change orders
(COs) relative to construction area (SF), cost ($), and average daily traffic, compared with typical
construction. Finally, the report outlines potential benefits and implications of using BIM for
infrastructure asset management by regional transportation authorities and the transportation industry
overall. Numerous stakeholders involved with horizontal construction and operation currently seek
information regarding the potentially significant benefits of integrating BIM into infrastructure asset
management. This research is important because it serves to assess and inform such an imminent
transition. The contribution of this research is to document and assess the role of BIM implementation
and potential impacts in order to use it in assisting throughout the life cycle of infrastructure assets.
