COBie – May 20, 2016
One thing is clear, the construction sector (architecture, engineering, contractors, owners, operators, users, suppliers) has been lagging virtually all other business sectors for decades with respect to productivity improvement.
I believe that the cause is largely cultural, however, any major improvement must be driven by Owners,and/or mandated by governmental regulation.
My reasoning is simple, Owners pay the bills. Thus as long as Owners remain satisfied with the status quo and/or remain “uneducated” with respect to proven business “best practices” and lean management processes, as well as supporting technologies, economic and environmental waste will continue to be rampant.
Currently, my outlook is somewhat pessimistic. If one looks at capability and knowledge specific to life-cycle facility management from an industry perspective, most has originated with the government sector, followed by higher education, state government, healthcare, process-based industries, etc. etc. Basically, Owners whose mission is dependent upon their built environment tend to create and follow life-cycle management practices. These are Owners that can’t adopt a “churn and burn”, or “run to failure” approach to facility management. These sectors can’t easily pack up and move if their facilities and physical infrastructure fail.
That said, even government owners, for the most part, have failed in any sort of department or agency-wide adoption of standardized best practices. This is true even for “simple” areas such as facility repair, maintenance, and renovation. Only the Air Force appears to come close to having any true adoption of robust, proven, best-practices in this regard, as well as associated training, etc., most notably with their SABER construction delivery structure.
In order to effect measurable productivity improvement in the “construction” sector, , I have put together a core requirements “checklist”.
1. Robust Ontology – Cost effective information management and information reuse can only be accomplished with a detailed set of terms, definitions, metrics, etc. This aspect is also critical to improved strategic and tactical decision support mechanisms.
2. An understanding of life-cycle management of the built environment from a collaborative, best-practices, process perspective as well as associated supporting technologies. Forget the traditional strategy-design-construction-demolish approach.
3. Commitment to a total cost of ownership perspective including both economic and environmental costs vs. our classic “first-cost” mentality.
4. “Trust but measure” – Owners MUST conduct their own internal cost estimating and associated capital planning and compare these to contractor estimates, with each party using the same data architecture (examples: RSMeans, masterformat, uniformat, omniclass).
5. Adoption of collaborative construction delivery methods such as Integrated Project Delivery, IPD, and Job Order Contracting, JOC, in lieu of antagonistic and inefficient design-bid-built, or even design-build.
6. STOP reinventing the wheel. Nothing noted here is “rocket science”. Many, if not most, processes, procedures, and technologies are readily available for anyone who does a bit of basic research!!! Also, stop with the focus upon BIM from a 3D visualization perspective! 3D tools are great, and add value, however, INFORMATION and PROCESS drive success.
Here’s a quick overview of a recent meeting discussing the legal aspects of BIM held July 2013.
‘Experts’ we gathered by RIBA Enterprises to discuss the topic. Key items a noted below:
1. CIC Protocol requires employers/onwers to put the protocol in place for all team members and upate the model production delivery table is updated and that an information manager is appointed.Project team members are required to provide specified levels of information, with a reasonable level of care.
2. Key to manage expectations early on in the project.
3. Protocol doesn’t really change liability in itself. That said, the concept of Level of Detail (LOD) become important in determining what information is considered ‘sufficient’ when team members are delivering information to “employers/owners”. Greaeter definition is required for both “data”, i.e. COBie and geometries.
4. Common data is a central requirement and robust management/business rules must be followed to assure development and use.
5. An information manager should not be confused with a design manager. The information manager role spans multiple disciplines / competencies.
6. Copyrights and other intellectual property issues are not any more complicated and appropriate licenses/rights should be established/obtained for owners/team use at the onset of the project.

Note: The above is not intended as legal advice of any type, but rather a simple report on the session.
It has been suggested by some that, rather than developing or implementing Uniclass2, we in the UK should switch to OmniClass, used in North America. John Gelder, Head of content development and sustainability, takes a critical look at the OmniClass Work Results Table, comparing it throughout with the Uniclass2 Work Results Table.
OmniClass is the North American equivalent of Uniclass2 and is promulgated by CSI (Construction Specifications Institute) and CSC (Construction Specifications Canada).
Broadly speaking OmniClass is in a similar position to Uniclass 1997, with much the same general limitations, though it is rather more unified. Uniclass articles corresponding to this one include Reclassification and The new Uniclass Work sections table. For a review of OmniClass in general, refer to the separate article OmniClass: a critique.
Like Uniclass Table J (aka CAWS), the OmniClass Work Results Table (aka MasterFormat) is geared mostly to the specification of systems and products, and so is focused on the construction phase. It doesn’t serve the whole project timeline, as it doesn’t have homes for high-level (early-stage) objects such as Complexes, Activities and Elements. This means that the Table can’t properly serve design-build and design-build-operate procurement (which, in the latter case, typically requires the contractor to be involved from the very beginning of the project, as part of a consortium). Other Tables within OmniClass must be used to structure specifications for Entities, Spaces and Elements. Tables outside OmniClass must be used for other object classes. These would then need to map to each other and to the Work Results Table, in order to properly integrate the specification component of the building information model (BIM) along the project timeline. Given the lack of congruence, this won’t be easy.
Even mapping between systems and products is problematic because, read with the non-OmniClass SectionFormat, there are no homes for System outline (or compositional) specifications. Indeed, Systems and Products are conflated. This means that the Work Results Table, plus SectionFormat, can’t properly serve BIM, which requires mapping between objects of different classes in the object hierarchy (e.g. this product is part of that system, this system comprises those products). Making this explicit in the specification requires outline specifications. We can’t rely on this mapping being delivered through the geometrical part of BIM (CAD) since many systems and products are not modelled geometrically at all.
The Uniclass2 Work Results Structure Table provides for outline (compositional) specifications all down the object hierarchy, including Systems-to-Products, so fully supports BIM. Table 5 illustrates this (left-hand column).
|Item||OmniClass Table 22 Work Results 2011 & SectionFormat 2008||Uniclass2 Work Results Table & Work Results Structure Table|

|System FM||Sub-group XX 01 00 Maintenance||System sections: System FM subsection|
SectionFormat has a home for the specification of performance and design criteria of products, which in turn are defined as including systems, assemblies, manufactured units, equipment, components, product types and materials. That is, SectionFormat doesn’t really distinguish between products, systems and materials, though OmniClass at large does (in the Products, Work Results and Materials Tables). ‘Performance’ at a higher level was in sub-group 01 80 00 Performance requirements in the 2004 edition of this Table, but this has been dropped in the 2011 edition. As it was actually mostly about elements rather than systems (e.g. 01 83 16 Exterior enclosure performance requirements), the idea is probably that this is specified using a specification aligned to the Elements Table.
The Uniclass2 Work Results Structure Table provides for performance specification of objects all down the object hierarchy, so fully supports contractor (and other) design. It also makes a clear distinction between Elements, Systems and Products (and so on) – this is essential for a rational approach to hierarchical object modelling. Table 5 illustrates this (left-hand column).
In the OmniClass Work Results Table, the commissioning and maintenance of systems (elements, actually) are not described in the system sections, but in separate sections in sub-groups 08 and 01 of each group, respectively, e.g. sub-group 09-08-00 Commissioning of finishes and section 09-01-70 Maintenance of wall finishes (see Table 6). This is rather inconvenient for those wanting to have everything about a given system collected together (though of course this could be managed through reporting in a digital specification tool such as NBS Create).
All aspects of each system, from design to operation, are collected in each of the System sections in the Uniclass2 Work Results Structure Table. Table 5 illustrates this (right-hand column).
The general sequence of sections within each Group doesn’t fully reflect construction sequence. For example, operation and maintenance should be last, and commissioning should be second-last, but this isn’t the structure at all. All of this is held in sections that precede those describing the thing yet to be designed and built. See Table 6.
The System section structure in the Uniclass2 Work Results Structure Table fully reflects construction sequence. See Table 5 (right-hand column).

The OmniClass Work Results Table has deficiencies, specifically with respect to serving the entire project timeline and all procurement routes, and supporting BIM. It has a construction phase focus, and so has no homes for the specification of high-level objects such as Complexes, so it can’t deal with early project stages. System operation and maintenance specifications are isolated from descriptions of the systems themselves, so it doesn’t serve the occupancy phase as well as it might. Together this means that the Table is not well-suited to non-traditional modes of procurement, such as design-build and design-build-operate.
The Work Results Table conflates systems and products, and has no homes for outline or compositional specifications. Together these mean that the Table doesn’t support hierarchical object mapping, a key requirement for a BIM specification. This is exacerbated by the Table – and OmniClass as a whole – not supporting classification of high-level object classes and systems. Without these object classes we cannot produce a complete ‘building’ information model.
Finally, the basic design-build-operate sequence is not implemented fully in the Work Results Table, nor in SectionFormat (e.g. a proposed FM subsection has not eventuated; system-wide performance requirements are not distinguished from those for ‘mere’ products). This makes the default structure rather messy.
BIM requires a unified approach to classification if it is to work well, e.g. with simple mapping between classification Tables. OmniClass cannot deliver this, as it stands. Uniclass2 can.

What is COBie?
COBie is a vehicle for sharing predominantly non-graphic data about a facility. The primary motivation for the use of COBie is to ensure that the Client as Owner, Operator and Occupier receives the information about the facility in as complete and as useful form as possible. Wherever possible, data should be recorded within COBie. The COBie dataset can additionally act as a guided index to the supplementary documentation, including 2D and 3D information.
COBie2 was created to provide a means for the faculties industry to communicate information about facilities so that the client can immediately take full and responsible ownership. It arose from the collaboration of the US Department of State, US Army Corps of Engineers, NASA, and the Veterans Association. In 2008 it was revised as COBie to ensure that it was relevant to facilities worldwide and was fully compatible with international standards for data and classification. Adopters of the COBie approach also include public and private owners, University of Indiana, University Southern California, in the UK Vinci Construction Ltd, and in Germany, The State of Bavaria.
COBie is a non-proprietary format based on a multiple page spread sheet. It is designed to be easily managed by organisations of any size and at any level of IT capability, allowing each of them to contribute efficiently to a single representation of the asset. It requires only information that is (or should be) available anyway, so it does not represent a change in the expected content, only in its usefulness and accessibility. The intent is to not create information that is not already available or produced as part of the existing processes. The aim is to structure and rationalise the information for re-purposing and use downstream. COBie also acts as an index to other documents. Overall COBie provides traceability and visibility of design, construction and handover decisions to all supply and client side stakeholders.
COBie is used for communication, as a means of information exchange between parties, particularly to the customer. Where automation is not in use, such as in the lower tiers of the supply chain, COBie information can be captured using direct entry into the spread sheet, often using cut-and-paste from existing schedules and documents. Parties including the client can use the COBie format as a primary document for managing the asset. Design development, construction management and asset management applications have had no difficulty in interfacing with the format.
COBie comprises sheets that document the facility, the levels (or sectors), spaces and zones that make up the function of the facility. These are then filled with the actual manageable systems and assets and details of their product types. During construction and installation these are amplified with information about the spares, warranties, and maintenance requirements. Throughout the process additional attributes, issues and documents can be associated to all these items.
2 COBie (Construction Operations Building information exchange) was developed by a number of US public agencies to improve the handover process to building owner-operators.
COBie data is accumulated throughout the life cycle
COBie transfers the information needed by the owner/operator to manage their asset efficiently. The principal use-case is therefore the handover of a facility after commissioning of the owner/operator. Typical questions answered by COBie include:
1. The handover of a facility to the owner/operator.
2. The capture of commissioning and survey information.
3. The reporting of the designed project ready for tendering.
4. The coordination of maintenance records of existing infrastructure.
5. The documentation of issues discovered throughout the life cycle.
6. The delivery of product data.
7. The reporting of design intent at the early design stage.
8. The comparison of briefing requirements against the designed and as built
COBie documents the asset in 16 consistent and linked sheets
We anticipate that our application of COBie will develop as the various technologies in the market mature, broadly in line with our “maturity levels model” described in appendix 3. For the majority of the five years of the life of this strategy we anticipate that most of the market will be engaged in or around level 2. For all deliveries at this level, COBie will be adequate as a transport mechanism but may well require additional development to cope with additional attached data, which some clients may start to wish for collection. There will also be a need to have a more robust system for processing the information as our understanding and needs grow. For this reason we have identified a stage where we would hold all delivered data in a database to enable these processes. This will need additional guidance as there would be a need to synchronise data, COBie, calculations and proprietary information at the same point in time.
BIM adoption remains a challenge due to the fact that its many supporters don’t focus upon it’s true relevance, the efficient life-cycle management of the built environment.
While any new technology has barriers to adoption, changing the “status quo”, the fundamental nature of how a business sector does business requires a major event. The cultural and process changes associated with BIM, namely the need for all stakeholders to collaborate, share information in a transparent manner, and share in risk/reward, remain chasms to be crossed by many/most. Fortunately, those currently or previously involved with Integrated Project Delivery and Job Order Contracting (the latter a form of IPD specifically targeting renovation, repair, sustainability, and minor new construction) have experience with these “novel” business concepts. Both IPD and JOC have proven track records and have clearly demonstrated the ability to get more work done on-time and on-budget to the benefit of all involved parties.
A key aspect of BIM, collaboration, can only be efficiently accomplished with a commonly understood and shared taxonomy including terms, definitions, and associated metrics.
So called “open BIM”, such as buildingSMART International’s Industry Foundation Classes (IFCs), are important to enabling collaboration as well as interoperability between BIM software applications. COBie, a naming convention for facility spaces/components, etc., and its counterparts OMINCLASS, including MASTERFORMAT and UNIFORMAT, etc. … can be leveraged and generated by IFC appears a goal worth additional focus on a local and global level. That said, support for COBie, OMNICLASS, IFC, etc. varies and, far from mainstream.
As noted in the IFC / COBIE Report 2012, BIM’s success depends upon the ability to:
There are multiple knowledge domains, technologies, and process involve in the life-cycle management of the built environment, all of which need a common data architecture, taxonomy, set of metrics, etc.
The IFC / COBIE Report 2012 correctly points out that pressing needs remain:
The need for standards
The need for guidance
The need for enhanced IFC import export routines from BIM applications
The need for agreed descriptions of who requires what data and when
The need for an improved audit trail to allow greater confidence in collaboration.
Also, and I paraphrase / embellish…
The Emperor is still naked!
Is the trend analysis of the Business Value of BIM in North America from 2007 through 2012 reality, or are many of us walking around with rose colored glasses?
I ask you, do you really believe the following statement ” Now in 2012, 71% of architects, engineers, contractors, and owners report they have become engaged with BIM on their projects …”. If you define BIM as the life-cycle management of the built environment supported by digital technology, I can tell you that either the survey is flawed… a lot of people don’t know what BIM is… or we have a lot of folks inflating the truth. There is NO WAY 71% of ANY of the groups are “engaged with BIM on their projects”…period, end of story.
Playing with Statistics? The 71% average appears to have been calculated by taking a simple average of the “adoption rate” from architects, engineers, and contractors” from three size classes of firms “small, medium, and large”. If I am correct, this is just plan WRONG. Most firms in the U.S. are small business, thus a weighted average must be applied. The “adoption rate” for small firms 50%… a number I also believe to be inaccurate.
I just came back from the NIBS Conference. This is without question, the most valuable, authoritative meeting relative to BIM in the United States. How many people were there you might ask? A few hundred at most.
So, what does any of this matter? Simple really. Until our industry stops the hype and focus on important issues relative to BIM, we will continue to be mired in inaction. The AECOO is the most unproductive business sector and also has the lowest rate of technology adoption. These are facts…. if one wishes to be interested in facts that is.
Here some thoughts as to where emphasis must be placed:
Is focus upon the 3D component of BIM an unfortunate distraction?
BIM, Building Information Modeling is the ability to create a dynamic information model of the built environment (above and below ground, inside and out, horizontal and vertical physical infrastructure) for use in all real property related activities: concept, rapid prototyping, planning, design, engineering, construction, physical and functional condition monitoring and management, financing, capital reinvestment, insurance, facility management, renovation, repair, sustainability, utilization, leasing, valuation, procurement, sale and decommissioning with appropriate shared, secure, and collaborative information access and use.
The advent of Cloud Computing, combined with the cost to capture, store, and process information falling to near zero, is enabling new capabilities for secure, real-time collaboration.
The altered world landscape relative to the built environment is upon us all. In addition to technology changes that are altering the ways we interact and conduct business on fundamental basis, there are economic and environmental imperatives. All of which lead to the AECOO (Architecture, Engineering, Construction, Operations and Owner) sector and its stakeholdings needing to collaborate to achieve better, quicker outcome, at less cost, and with less risk.
Key challenges to BIM in terms of its true potential, the life-cycle management of the built environment, include:
– The development of uniform standard process, terminology, and technology environments for the new BIG DATA world , encompassing all ‘built environment related knowledge domains, competencies, and activities.
– Clear organization and classifications of information and associated access rights and rights to use, enabling appropriate, uniform basis intra and international use.
– Workflow-based Cloud-computing services environments, and plug-ins that are vs. monolithic traditional software frameworks which are web enabled via virtual server, or even traditional 3-tier web applications such as .NET. 4-tier applications are needed with the ability to link and reuse information in any manner relative to identity/location, building, area, floor, room, occupancy, use, physical and functional conditions, standardized and actual costs (material, equipment, and labor), et al… – to provide common ‘highly secure’ models for short and long term decision support.
– The acceptance and increased use of collaborative construction delivery methods such as Integrated Project Delivery (IPD) and Job Order Contracting (JOC). The latter a form of IPD specifically targeting facility renovation, repair, sustainability, and minor new construction projects.
– AUTHENTICATION, ACCESS CONTROL, COLLABORATION, AND STANDARDS … 4Clicks Solutions is about to release a powerful new Cloud Computing solution called CEASEL. It focuses upon transparent construction cost estimating and efficient project delivery. Each user to controls their own ‘domain’ and access policies (ie ‘who’ can access ‘what’ data, ‘when’ and ‘how’ ). Data in NEVER deleted and ALL user access and activities are tracked.. .the best form of security. “Data independency” and appropriate access for all asset owners, managers, and service providers is supported. Project development time is reduced because users don’t need to create an identity store and access control system for each project, and projects, estimates, etc. can easily be updated and re-used.
New authentication methods or new kinds of user credentials can be adopted by upgrading just the authentication service. Associated contracts, projects, and estimates don’t need to be re-coded. Changes to access control policy can be made quicker and more easily because it is consolidated in the one place.
Dedicated and focused security service leads to better overall security – compared with each organization having a part-time resource for security management.
Security improvements benefit all projects at the same time.
Less time and effort is devoted to security administration as administrators only need to understand and use one security framework rather than a different one for each project.
Errors are reduced because there is no duplication of identity data and access control policy.A unified view of identity and access control policy is achieved for each user, without breaching the security of other users.
Simplified , auditing and reporting.

I am writing this from Washington, D.C. while participating in the NIBS Building Innovation 2013 Conference. The buildingSMART alliance conference is part of this gathering under the title “Integrating BIM: Moving the Industry Forward.”
BIM education and practice requires focus upon process and associated return-on-investment. Robust communication and adoption of standard and/or “best practice” construction planning and delivery methods specific to efficient life-cycle management of the built environment are sorely needed.
It is amazing that Integrated Project Delivery – IPD, and “IPD-lite”… the latter being Job Order Contracting and SABER which are forms of IPD specifically for renovation, repair, sustainability and minor new construction… are not being brought to the forefront as critical aspects of BIM. It is the construction planning and project delivery method that sets the tone of any project and ultimately dictate relationships and associated successes or failures.
Collaboration, transparency, and performance-based win-win relationships are necessary components of a BIM-based philosophy. Yet, these and other critical aspects; including defensible, accurate, and transparent cost estimating and standardized construction cost data architectures, are neither in forefront of current thinking nor receiving an adequate allocation of resources.
Far too much emphasis continues to be place on the 3d visualization component aspect of BIM, IFC format pros and cons, and other “technology” areas.
Technology is NOT what is holding back BIM, it is the apparent lack of understanding of … and associated failure to adopt … facility life-cycle management processes… combined and what can only be described as a pervasive “not invented here” attitude.
Many of of our peers are reinventing the wheel over and over again at tremendous cost to all stakeholders…Owners, AEs, Contractors, Subs, Oversight Groups, Building Users, Building Product Manufacturers, …not to mention our Economy and our Environment, vs. sharing information and working toward common goals.
