Pathways from design towards construction and use, inputs and outputs
Published in James Harty, Tahar Kouider, Graham Paterson, Getting to Grips with BIM, 2015
James Harty, Tahar Kouider, Graham Paterson
At first viewing, COBie output does present the unfamiliar user with a bewildering array of spreadsheet fields, implying a complexity of organisation and content. Having said that, the protocol does offer a logical and structured template for the assimilation and exchange of metadata over time. Plus, COBie is now embedded in the UK Government’s suite of BIM standards which define inputs and outputs for a BIM Level 2 compliant project. Ultimately, the timing and content of information being extracted from digital environments will be project and process specific. COBie data is just one from a range of outputs which may be pulled from BIM models. Perhaps the key difference compared with more traditional methodologies for generating and handling construction data is that expectations for outputs (‘deliverables’ in BIM jargon) are flagged up with much greater precision from the outset, particularly when the PAS 1192-2 protocol is applied as a framework for information management.
BIM: A collaborative way of working
Published in Derek Clements-Croome, Intelligent Buildings, 2013
Collaboration and the sharing of information are critical success factors for BIM. There are two crucial times when data exchange will have a huge impact on overall success: At the award of the building contract, when the design model is assigned to the contractor, who takes responsibility for owning and delivering it.On completion of the project, when the asset model, containing all of the built information necessary to operate the building, is handed back to the client by the contractor. Adopting the Construction Operation Building Information Exchange (COBie) format is the recommended way of ensuring the information delivered back to the client is as useful as possible.
Post-construction / OGC Gateway 4–5 / RIBA Plan of Work Stage 6
Published in Duncan Cartlidge, Construction Project Manager’s Pocket Book, 2020
Construction Operations Building Information Exchange (COBie) is a data format for the publication of a subset of building model information focused on delivering building information not geometric modeling. It is closely associated with BIM and was devised by Bill East of the United States Army Corps of Engineers in 2007. COBie is formal schema that helps organise information about new and existing facilities. It is general enough that it can be used to document both buildings and infrastructure assets. It is simple enough that it can be transmitted using a spreadsheet (Excel) format. It is a means of sharing structured information, just like BIM, except that it is not as comprehensive as a full BIM, but nevertheless it is a step in the right direction.
IFC-based performance data checking for ventilation system design
Published in Journal of Asian Architecture and Building Engineering, 2023
Construction operations building information exchange (COBie) is a performance-based specification for facility asset information delivery, focused on the operation and maintenance of equipment (US ARMY Corps of Engineers et al. 2021). Based on the COBie framework, a fire safety equipment inspection and maintenance system was proposed by combining BIM information and augmented reality (AR) environments (Chen, Lai, and Lin 2020). The UK National Building Specification (NBS) developed a BIM object standard based on information, geometry, and function requirements. It provides a BIM library from building fabric systems to mechanical and electrical objects (NBS 2019). Users can download the BIM templates for the air handling unit (AHU), diffuser, and other equipment, including the specified IFC Psets. Therefore, one can use Psets of BIM objects.
The interaction of BIM And FM through sport projects life cycle (case study: Sailia training site in Qatar)
Published in HBRC Journal, 2022
COBie is a part of the National BIM Standard in the United States. Information is exchanged from one process of the facility lifecycle to the next as a common practise. The purpose of the information exchange is to provide facility managers with information on the need to maintain and operate their facilities. COBie distinguishes itself from other standards because it establishes information flows that allow information to be placed in an effective fashion. When information about an air handling unit is submitted into COBie, for example, the data can be imported and exported into COBie compliant software, which can then be used to take action via automated reports [26]. COBie advantages include reducing data loss and related expenses connected with the physical transfer of project information after the project’s conclusion and increasing the possibility of getting relevant information in a timely way [19]. While not every attribute data must be included in the BIM, the required data should be delivered via compliant files. COBie will be able to connect the required space, zone, and equipment data to the Record BIM elements. A shared primary key will be allocated to the BIM objects and their related properties in COBie and the model. Team members should now document how they adhere to COBie’s standards in their BIM process [19].
A methodology to integrate maintenance management systems and BIM to improve building management

A BIM model for facility management provides visualization, access to the precise location and relationships of building systems and equipment, and access to accurate existing condition attribute data (General Services Administration (GSA)) 2011). The concept of Central Facility Repository (CFR) proposed by the General Services Administration (GSA) defines a comprehensive information system built around a central facility database, which serves as the data foundation for FM-related software applications (Gao and Pishdad-Bozorgi 2019). They have developed three tiers of requirements that merely apply to new constructions or major renovations (Teicholz 2013). One of the main challenges is the interoperability between BIM and FM technologies in data transfer stages (Kassem et al. 2015). For this purpose, IFC (industry foundation classes) and COBie (construction operations building information exchange) can be useful to achieve data mapping and data integration between BIM models and FM systems (Marmo et al. 2020). COBie is a framework for organizing data developed and accumulated during a building project for delivery to facilities owners and operators (Teicholz 2013).
