March 2010 COBie Challenge: VELA
NATIONAL FACILITY MANAGEMENT & TECHNOLOGY TRADESHOW
The Construction Operations Building information exchange (COBie) information exchange format is a non-proprietary platform for the exchange of facility life-cycle data needed by facility managers. This page provides links to information used to evaluate the product listed in the table below against the requirements of the Facility Handover Model View Definition (PDF 1.4 MB) and the COBie draft specification (DOCX 36 KB). COBie is based on an underlying Industry Foundation Class (IFC) Facility Management Model View Definition (MVD) format. The information content of the FM Handover MVD and COBie is the same, the format of the two models are interoperable using a freely published bimServices.
The specific version of COBie exercised in this challenge was COBie 2.26. Version 2.26 made slight modifications to the organization of warranty data to resolve issues related to the practical usage of warranty information identified in the Dec 2009 COBie Challenge.
In this challenge, design software vendors created and exported files for a two-story, duplex apartment building described in the March 2010 COBie Challenge. Construction and commissioning software systems imported and augmented this information. Finally, maintenance and asset management software consume this facility handover information. The sections below indicate the specific COBie produced and/or consumed by the designated software vendor.
General Product Information
COBie Producer Challenge
During the project, COBie information may be produced following design, construction, or commissioning. The following table identifies which of the information exchanges were the subjects of the COBie Producer Challenge for the subject product.
To assess the quality of the COBie file produced by the subject free software, bimServices was used for compliance checking. To evaluate COBie export routines the number of deviations between the COBie requirement the vendor's file were identified and evaluated based on the total time to correct these deviations. "Simple" deviations are those such as the need to include authorship information for records within a COBie deliverable. The resolution of simple deviations is simple (estimated as 30 seconds each) since the information may be copy and pasted to solve the problem. "Complex" deviations require additional effort (estimated at 120 seconds) to resolve since a this type of deviation results from a COBie row not having specific referential information, such as type, space, zone, or system, needed to correctly identify the data row. For example, a component that does not identify the space in which the component is installed will result in a complex deviation.
Construction – Facility Handover Deliverable
COBie Consumer Challenge
During the project COBie information may be consumed during design, construction, commissioning. The following table identifies which of the information exchanges were the subjects of the COBie Consumer Challenge for the subject product.
During this COBie Challenge the vendor consumed the coordinated design stage COBie file (XLS 631 KB) for the reference project to begin the capture of construction information.
Currently the product requires the user to paste COBie spreadsheet data to pre-specified import templates used in VELA to import the COBie data. Future implementations of COBie import should eliminate this requirement. Please contact the software vendor directly to determine manual data manipulation requirements.
To assess the quality of COBie file import the author conducted a webinar with the vendor in the weeks leading up to the COBie Challenge. During this meeting the vendor was required to provide a live demonstration of their use of the COBie data and answer a battery of questions to determine if the project data was correctly loaded. The results for the consumption of COBie data for the sample product, as identified in the tables above, are listed in the table below:
2 The application has this information but has not exported it to COBie as part of the March 2010 challenge. It is expected that the warranty information will be demonstrated in a future COBie challenge.
