Bridge information modelling (BrIM) invokes stakeholder collaboration, supported by policy and process frameworks, combined with interoperable technology, to manage information and enable effective decision making throughout the lifecycle of a bridge asset. This paper considers the application of BrIM for the proposed rehabilitation of a heritage listed viaduct. The structure under consideration is the landmark Chetwynd viaduct in Cork (Ireland), which formed part of the Cork-Bandon railway infrastructure constructed in 1851 and decommissioned in 1961. As with infrastructure of its type, few as-built records exist. Consequently, the geometry, material properties and condition of the existing structure are required to inform the initial feasibility assessment and subsequent design, construction and operation of this viaduct asset. Respective BrIM and traditional approaches to the data capture phase are outlined and compared in terms of time, expertise and deliverables. The significant deliverables from the traditional approach include a three-dimensional (3D) solid model and independent 2D drawings. Significant deliverables achieved using a BrIM approach include an intelligent parametric 3D model and associated 2D drawings, as well as integrated datasets representative of the 'as-is' structure. Based on reported research, the initial effort and time expended on model creation in particular will enable significant future benefits. [ABSTRACT FROM AUTHOR] |
