Standard + Specification + Workflows = Success
After the release of COBie 1.0 software companies asked for, and got, a consolidated data model, not a data model focused on individual construction work flows. The initial NBIMS-US COBie standard, therefore, reflects the needs of the software companies implementing COBie during design, construction, and handover. As of NBIMS-US V3, the COBie technical specification is virtually complete. While future COBie versions may tweak one or other specific aspects, the standard-obtaining information that matches that found on drawing is complete and implemented in many Commercial-Off-The-Shelf (COTS) software products.
The COBie Construction Templates return to the essential idea first introduced in COBie Version 1.0. Namely, that the workflow to capture and consolidate COBie during construction is more critical to the effective use of COBie than is the underlying standard. The COBie standard was necessary, but insufficient. The COBie standard plus the set of contracted workflows, based on a standard specification, that require COBie are the two minimum requirements to begin making COBie a success on your construction projects.
The draft COBie Unified Facilities Guide Specification requires two types of COBie deliverables. The first are COBie-specific deliverables. These deliverables accompany all sets of drawings exchanged at major project milestones. The quality standard required by bSa Challenge events is that the information provided in COBie-specific deliverables match the information found in the equivalent design or construction drawing schedules. The software that produces such drawings have now been proven to accurately produce a COBie data as simply as producing a printed copy of the drawings.
The draft COBie Unified Facilities Guide Specification (UFGS) also requires COBie-formatted submittals. These submittals contain the - exact same - information found in traditional construction contracts. The inclusion of COBie only requires that the format of these existing submittals be standardized. Prior to the release of the COBie Construction, construction managers would have to develop their own templates by copying subsets of a COBie design file and then hiding or filtering data. In this way equipment installation worksheets could simply look like the existing submittal, and not an entire "confusing" COBie data set.
Initially, COBie-formatted submittals contain only the information found in the design stage. As the project progresses the COBie-formatted submittals contain more and more of the as-built project information. The collation of information in COBie-formatted submittals could be accomplished manually, with construction-oriented software, or with a building information model server. The choice of specific tools to be used should be documented in the COBie Information Delivery Plan.
COBie Construction Templates
To use the COBie Construction Templates, the construction manager, or owner, only need look at the existing paper-based deliverables. If the paper deliverable is provided, then the contractor can simply substitute the COBie Construction template for the paper-based deliverable. The table below lists each of the required deliverables found in handover-related specification sections and identifies the corresponding COBie Construction Template.
An initial version of the templates has been produced in Excel format and is available for download, and there are also plans to provide code libraries that convert these template files to COBie spreadsheets.
