LOSS OF INFORMATION DURING DESIGN & CONSTRUCTION FOR HIGHWAYS ASSET MANAGEMENT: A GEOBIM PERSPECTIVE

Abstract

Abstract. Modern cities will have a catalytic role in regulating global economic growth and development, highlighting their role as centers of economic activity. With urbanisation being a consequence of that, the built environment is pressured to withstand the rapid increase in demand of buildings as well as safe, resilient and sustainable transportation infrastructure. Transportation Infrastructure has a unique characteristic: it is interconnected and thus, it is essential for the stakeholders to be able to capture, analyse and visualise these interlinked relationships efficiently and effectively. This requirement is addressed by an Asset Information Management System (AIMS) which enables the capture of such information from the early stages of a transport infrastructure construction project. Building Information Modelling (BIM) and Geographic Information Science/Systems (GIS) are two domains which facilitate the authoring, management and exchange of asset information by providing the location underpinning, both in the short term and through the very long lifespan of the infrastructure. These systems are not interoperable by nature, with extensive Extract/Transform/Load procedures required when developing an integrated location-based Asset Management system, with consequent loss of information. The purpose of this paper is to provide an insight regarding the information lifecycle during Design and Construction on a Highways Project, focusing on identifying the stages in which loss of information can impact decision-making during operational Asset Management: (i) 3D Model to IFC, (ii) IFC to AIM and (iii) IFC to 3DGIS for AIM. The discussion highlights the significance of custom property sets and classification systems to bridge the different data structures as well as the power of 3D in visualizing Asset Information, with future work focusing on the potential of early BIM-GIS integration for operational AM.

Toward cognitive digital twins using a BIM-GIS asset management system for a diffused university

“…Furthermore, Ma and Ren (2017) identified three suitable domains to apply GeoBIM: planning and design (P&D), O&M, and the demolition phase. Floros and Ellul (2021) highlighted how BIM-GIS integration simplifies IM throughout the whole lifecycle and improves decision-making in the pre-construction phase. Other studies highlighted that the activities which benefit most from BIM-GIS integration during the O&M phase are AM and crowd simulation with a focus on risks, energy, security, heritage, and facility management (Ma and Ren, 2017;Song et al, 2017;Garramone et al, 2020;Heaton and Parlikad, 2020;Fan et al, 2021;Shkundalov and Vilutienė, 2021).…”

Building Information Modelling Facility Management (BIM-FM)

“…One approach has involved the creation of digital FM systems, which are now used extensively. Popular systems for existing buildings can typically be categorised as Asset Information Models (AIMs) [5,6], Computer-Aided Facilities' Management 2 of 24 (CAFM) [7][8][9] and Computerised Maintenance Management Systems (CMMSs) [10][11][12][13]. Often, these systems will be spreadsheet-based.…”

“…Fundamentally, "what is sent must be the same as what is understood" [72], meaning data exchange must not involve so much data loss or conversion that it becomes unrecognisable. Floros and Ellul [6] converted a 3D model to IFC and then the IFC model to both AIM and GIS for AIM and recorded the information losses. They encountered semantic information losses at all stages and geometry losses for the IFC-AIM and IFC-GIS for AIM conversions.…”

Data integration through a bim-gis web platform for the management of diffused university assets

“…The adoption of open standards such as IFC (Industry Foundation Classes) for BIM and CityGML for GIS (Laakso and Kiviniemi, 2012) would facilitate interoperability and unchangeability among heterogeneous dataset process which translates a dataset into a standardized format; Common guidelines: definition of guidelines shared between actors and stakeholders to avoid loss of information during exchanges, "GeoBIM" models instead of BIM and GIS separately (Floros and Ellul, 2021). Many studies analysed the most suitable fields where BIM and GIS can be better applied.…”
