Building Information Modeling (BIM) for Bridges and Structures

项目名称：	Building Information Modeling (BIM) for Bridges and Structures
摘要：	The pooled fund project will provide the primary funding mechanism for American Association of State Highway and Transportation Officials (AASHTO) Subcomittee on Bridge and Structures (SCOBS) T-19 to perform the duties of governance and stewardship of Building Information Management (BIM) for Bridges and Structures. The objective of this proposal is to provide technical support for the implementation of Building Information Modeling (BIM) for Bridges and Structures under the direction of AASHTO COBS Technical Committee on Technology and Software (T-19) and the Transportation Pooled Fund TPF-5(372) Technical Advisory Committee (AASHTO COBS T-19/Pooled Fund). BIM has been widely used in the commercial sector for vertical construction to manage projects from conception through design, fabrication, construction and future asset management and maintenance. Although some fabricators who perform work on both building construction and transportation structures have begun employing BIM tools in the fabrication of bridge components, BIM use in transportation infrastructure is severely limited due to the lack of standardization. To take advantage of the efficiencies associated with the use of BIM in transportation structures, a comprehensive strategic plan by AASHTO COBS T-19 is needed. As a first step, AASHTO COBS T-19 initiated a study that was funded by NCHRP. The NCHRP project 20-07 Task 377 titled �Standardized Format for Bridge and Structure Information Models� presented a framework for BIM implementation roadmap and provided AASHTO COBS T-19 a list of actionable items. Following the conclusion of the NCHRP study and after extensive deliberations, AASHTO COBS T-19 identified a path forward for BIM implementation for bridges and structures. The initiative involved the following key decisions: (1) Identity: The initiative is being named BIM for Bridges and Structures, as the name encompasses the goal of this endeavor without potentially violating trademark rights. (2) Governance and Stewardship Framework: The BIM implementation roadmap involves the identification of a governance structure. The selected framework will be overseen by AASHTO COBS T-19 in collaboration with the AASHTO Technical Joint Committee on Electronic Standards, FHWA, and other various stakeholders. (3) Data Exchange Schema: Multiple schemas for the governance framework of BIM for Bridges and Structures were discussed, with the decision being made to develop a Model View Definition (MVD) compliant with Industry Foundation Classes (IFC) data models. IFC is the industry standard in the vertical industry and is well established. buildingSmart International, the global organization with IFC oversight, also has global initiatives working toward implementing BIM for roads and bridges in other countries, making a natural alignment with IFC the most appropriate approach. (4) Funding Mechanism for Support: It became evident through the discussions that the initiative to move BIM for Bridges and Structures into standard practice would require much more effort than could be taken on solely by T-19 members. The committee agreed that the use of a consultant/contractor would be necessary to accomplish many of the tasks needed to move forward. The committee discussed several funding options, ultimately deciding on two sources: FHWA and pooled fund study.
