BSI BS EN ISO 19650-4 – Executive briefing
Preface ‘The ISO 19650 series makes manageable the opportunities around digitization of the built environment sector’ Digitization offers great potential for improving the efficiency, accuracy and completeness of the information around the design, construction and operation of assets which constitute the built environment. However, a challenge remains as to how teams and supply chains, that are often diverse and changing, can contribute to and benefit from the authoring and delivery of information, alongside providing other services and products. To do so, all participants need to embrace ‘information management’ to have a sound basis for decision-making and collaboration. While there are many standards that address information management, security management, risk management and quality management within organizations, the ISO 19650 series specifically addresses how the built environment sector can collaborate, coordinate and contribute together to obtain the best outcomes. For some participants, the answer involves using building information modelling (BIM) to break the dependency on documents and drawings. BIM allows the lead designers, engineers and facility operators to ensure that all the objects, properties, shapes and connections are coordinated and consistent. The ISO 19650 series has progressively replaced the BS 1192 and PAS 1192 series, reflecting the rising international interest in the success of the UK’s approach to information management and modelling since 2010. The publication of BS EN ISO 19650-4 is an opportunity to secure the benefits of trustworthy information project and asset management teams.

Introduction ‘ISO 19650 is a mechanism for generating trust’ Information management processes for asset design, construction and operation have been standardized by ISO 19650 to protect the information about assets from missing, contradictory, low-quality or inconsistent information. This increases the trustworthiness of information to support decision-making and action. BS EN ISO 19650-1 formalizes the key concepts and principles, such as the procurement of information (alongside other deliverables such as the design, construction, services or products and systems), the use of a Common Data Environment (CDE) and the federation of information from parties with different responsibilities. BS EN ISO 19650-2 and BS EN ISO 19650-3 apply these to project delivery and to asset management. BS EN ISO 19650-5 overlays the need for securitymindedness. These processes are necessary to ensure trustworthy and clear relationships, even as project and operational participants come on board or leave. The processes in BS EN ISO 19650-2 and BS EN ISO 19650-3 around the CDE generate trust between parties that their information is respected and used appropriately. It generates trust that information accepted as project information and asset information has been through separate review and authorization steps and so should be reliable and consistent. BS EN ISO 19650-4 looks at the quality and utility of the information that is exchanged in these processes and lays down criteria for both the formats of the information and for the content of the information. Ensuring that information is as accessible and consistent as possible is the crucial ingredient in securing value for all participants. The standard applies to each individual information exchange in project and asset management and establishes a common list of criteria which must be met, if the value of the overall information model is to be preserved. BS EN ISO 19650-4 focuses on these decisions to generate trust that the information that is first shared and then accepted is useful for the purposes it is intended to fulfil and remains as useful as possible thereafter. That usefulness depends on meeting the criteria for information quality at the same time as meeting the project or asset requirements.

The importance of BS EN ISO 19650-4 1 What does the standard do? It complements the existing ISO 19650 suite by addressing the quality of exchanged information, by identifying the common criteria for selecting software applications, for choosing data formats and for evaluating information exchanges. It emphasizes the immediate, medium-term and long-term uses of information. It is intended to simplify the preparation of information requirements, information standards and execution plans by providing a common expectation. It addresses repeatability of authoring, checking and approval processes and gives criteria for when and how often information should be shared.
2 Who is the standard for?
• Anyone developing information requirements, information standards, as well as information production methods and procedures
• Anyone generating information • Anyone involved in CDE approval and acceptance procedures • Anyone concerned to support environmental, economic or social sustainability with trustworthy information
• The standard introduces the terms ‘information providers’, ‘information receivers’ and ‘information reviewers’ so that all the parties referenced in BS EN ISO 19650-2 and BS EN ISO 19650-3 can fulfil their duties and roles

3 The benefits of using the standard
‘Part 4 secures the benefits arising from collaborative and interoperable building information modelling’ • Provides a proportional and sustainable approach to information exchange • Ensures the immediate delivery of information does not limit its future use • Clearer provisions on the use of open standards for information • Greater confidence in the usefulness and long-term relevance of information • Benefits accrue across the asset life cycle:
• immediately, a reduction in rework by making criteria explicit in advance • in the medium term, greater accuracy and efficiency of information production • in the longer term, an increase in the value and relevance of information to decision-making
• Limits the exemption of information containers from the complete CDE process to evidence and certificates
4 How to implement the standard Make sure BS EN ISO 19650-4 is included when specifying or offering compliance to the ISO 19650 suite, particularly for qualification and appointments. This will allow you to eliminate informal quality criteria from documents and replace them with references to BS EN ISO 19650-4. Make sure that software applications are chosen that can import, federate and/or link information to support collaborative working, along with software applications that can import, export and support issue and risk management tools. Bear in mind that information models and datasets will always be easier, faster and more accurately checked than drawings and documents especially if appropriate applications and processes are deployed.
5 Challenges and pitfalls in using the standard
• Inertia and resistance to changing contracting practice to secure medium and long-term benefits • COBie is now defined by direct reference to US NIBS COBie V3 • There remains a need to balance quality assurance during information production and quality control afterwards
6 What are the downsides/impacts?
• Project requirements and asset requirements still need to be specified and met, alongside information requirements
• Need to use the informative annex lists of open schema and open formats appropriately

The importance of the UK National Annex to BS EN ISO 19650-4 1 What does the National Annex do? The National Annex provides the specific implementation details for the UK. It confirms that Uniclass is the preferred classification tables for the sector. It specifies Uniclass classification for drawings, specifications, models and other documents, and it specifies the Uniclass classification tables for types of entities within information containers. It provides the common classification and naming of life cycle stages as per BS 8536 (previously found in CIC and RIBA documentation). It sets out specific criteria for conformance, continuity communication and for whole project and asset information containers. It replaces the COBie specific requirements previously found in BS 1192-4 with references to the US NBIMS V3 standard and downloadable resources.
2 Who is the National Annex for? Anyone applying the UK BIM Framework or ISO 19650 within the UK.
3 The benefits of using the National Annex
• It provides clearer and updated provisions on classification • It allows for closer alignment of COBie usage to international specifications 4 How to implement the National Annex Cite the National Annex specifically within in-house information requirement standards as well as information production methods and procedures. This should allow the elimination of informal quality criteria from documents and their simplification. Use the National Annex to implement the consistent UK approach to classification, geo-location and linear referencing. COBie is relevant to handovers where the owner/operator has enterprise systems such as CAFM, maintenance management or portfolio management applications in place. The UK conventions for COBie now appear in the National Annex and in online resources.

5 Challenges and pitfalls in using the National Annex and the withdrawal of BS 1192-4
• COBie remains a key part of the UK BIM framework, even with the withdrawal of BS 1192-4 • Owners and operators of facilities still need to consider their asset breakdown structures, cost breakdown structures and work breakdown structures, individually
• The UK conventions for COBie now appear in the National Annex • UK resources are now downloadable, rather than appearing in printed form • The classification of risks to Uniclass is not yet published which may affect the use of risk registers and the COBie ‘Issues’ table
6 What are the downsides/impacts of the National Annex and the withdrawal of BS 1192-4?
• The recommendations on classification tables have been changed since BS 1192-4 was published
• Uniclass 1.4 has been superseded by the more dynamic Uniclass, so care is needed to maintain and update classification picklists in COBie templates
7 How does this relate to delivery and operations of assets?
• Creating and maintaining accurate asset information is critical
• to meeting corporate and legal expectations • to enable an asset to be efficiently and practically maintained and operated • to support long-term social, environmental and economic needs

Wider context • The transitioning of PAS 1192-6 to become BS EN ISO 19650-6 has begun and should be
published in 2–3 years’ time. In the meantime, the PAS 1192-6 remains valid and a key part of the UK BIM Framework
• BS EN ISO 7817 ‘Building information modelling — Level of information need’ series will help the preparation of testable information requirements
• BS 8644-1 makes specific recommendations about fire safety information • BSI Flex 1965 supports the specification of information management services • buildingSMART is developing IDS as a format that can configure authoring tools and checking tools
Suggested next steps
• Reference the standard in your project and asset information requirements, information standard, as well as information production methods and procedures
• Re-consider best practice for data formats in your project or asset information methods and procedures
• Revise your BIM Execution plan to make sure sharing is preceded by rigorous checks and to make sure that sharing is followed by rigorous checks before accepting as published
• Reference and implement the National Annex
