New Era of BIM Lifecycle Implementation
Part 1: An Overview of How The ISO 19650 Series Affects Asset Management By Dr. Xifan (Jeff) Chen and George Broadbent
Introduction The understanding of Building Information Modeling (BIM) has gradually expanded from a 3D replacement of traditional 2D CAD drafting to a very broad term that describes the process of creating and managing digital models of buildings (or other structures). As a result, the demands and expectations of BIM workflows are increasing. Asset owners and clients have recognized and are excited about the pres- ent and future benefits coming from BIM utilization during the asset delivery phase. They have already started to outline BIM’s integration in the operational phase as the sensible next step in BIM’s Lifecycle Implementation. Despite the slower than hoped for pace of the AECO industry’s glo- balization and adoption of its processes, requests for collaborative approaches for collecting, creating, managing, and sharing informa- tion have intensified. The advent of the ISO 19650 series is a timely response to the call for a standardized process to regulate BIM-related information management throughout the entire asset life cycle. ISO 19650 ISO 19650’s development has been based on the UK 1192 series, which was produced following the government’s BIM Level 2 initia- tive. As the first international BIM ISO Standard, ISO 19650 enables teams around the world to enhance efficacy and efficiency through a set of common information management approaches. Currently, ISO 19650 parts 1 and 2 have been released, and focus on concepts and principles, and delivery phase of the assets, respectively. Parts 3 and 5 are advancing and scheduled for release in 2020. Part 3 will con - centrate on the operational phase of assets, and part 5 will focus on the specifications for a security-minded approach to the management of information as it relates to sensitive assets. The ISO 19650 series, along with a region-specific requirements appendix will comprehen - sively define the collaborative process for the effective management of information through the delivery and operational phase of assets when BIM is being used for the first time on a global basis. PIM & AIM & Digital Twin The Project Information Model (PIM) and Asset Information Model (AIM) have been defined by BIM Level 2 as adjoined stages of Com - mon Data Environment (CDE). As shown in Figure 1, the PIM is de- veloped during the delivery phase of a project, starting from a design intent model, and eventually becoming an as-built model to represent the real as-constructed condition of the built asset. After that, the PIM transfers to the AIM to continue informing asset management (AM)/ facility management (FM) during the operational phase. Ideally speak-

ing, the AIM should be considered the “digital twin” of built assets, or the digital replica of vital physical assets, processes, locations, systems, and devices that can be operated and analyzed for various purposes. When aligned with BIM Level 2, ISO 19650 cogitates over principles and processes to refine data interoperability and integrity during the handoff from PIM to AIM. Figure 2 illustrates the transition from PIM to the Facility Information Model (FIM) and the relationship between a Digital Twin and its corresponding physical assets.

Use CDE to Fill the Gaps CDE refers to the single source of information used to collect, create, manage, and share both graphical and non-graphical data for all project stakeholders. In ISO 19650-2, it clearly states that “…Prior to gener - ating information, each task team shall check that they have access to the relevant reference information and shared resources within the project’s common data environment….”
