What are ISO standards

In the context of BIM, ISO standards serve to regulate not only technical aspects (formats, data exchange) but also informational processes (how project data is generated, managed, and shared). This helps to reduce ambiguity, errors, and inefficiencies, increasing the consistency and quality of information throughout the entire lifecycle of the project.

Who defines ISO standards

ISO standards are developed by the International Organization for Standardization (ISO), an independent and non-governmental entity composed of national standardization bodies from about 160-170 countries.

The structure is roughly as follows:

technical committees: groups of international experts (professionals, academics, businesses) who propose, develop, and review the standards;
voting procedures: draft standards are voted on by ISO members. A draft can evolve into a Final Draft International Standard (FDIS) before being approved;
publication: if approved, the standard becomes official and is published internationally.

How ISO certification works

It is important to make a key distinction: ISO does not issue certifications.

ISO is responsible for creating the standards, but certification (the verification that a company or process complies with the standard) is entrusted to independent bodies, known as certification bodies.

Here’s how the certification process works:

accreditation of certifiers: certification bodies must be recognized as competent, usually through an accreditation body;
audit: the certifying body conducts an audit on the systems, processes, or documentation of the applicant to verify compliance with the specific ISO standard;
issuance of the certificate: if the audit is successful, a certificate is issued (e.g., “ISO 9001:2015 certified”);
surveillance/renewal: the certificate is not eternal; there are usually periodic audits (surveillance) and a renewal cycle (e.g., every 3 years, depending on the certification scheme).

What are BIM ISO Standards and why are they important

The BIM ISO Standards are international standards that define criteria, processes, and requirements for the structured management of information throughout the lifecycle of a project. These standards not only regulate the technical aspects of the information model but also the way in which the various stakeholders involved (designers, contractors, clients, managers) produce, organize, exchange, and validate data.

Their importance arises from the increasing complexity of projects and the need to operate in increasingly collaborative digital ecosystems. Without shared standards, each party would define its own procedures and formats, making communication difficult and increasing the risks of document inconsistency, duplication, operational errors, and changes during the project.

The ISO standards applied to BIM (particularly the ISO 19650 series) provide a structured and universally recognized reference that ensures information consistency, interoperability, and quality of processes, regardless of the national context or the software platform used.

Why international standards are needed in BIM

The adoption of international standards in BIM is essential for several reasons:

Interoperability between different systems and stakeholders

BIM involves heterogeneous disciplines (architecture, structures, systems, computation, construction management, facility management). Without a common language, information exchange would become a fragmented process, with continuous conversions and data losses.

Structured collaboration and process control

BIM projects require all participants to operate in a coordinated manner. ISO standards establish roles, responsibilities, communication flows, and necessary documents at each stage, reducing ambiguity and misunderstandings.

Reliability and repeatability of information

An international standard allows for the replication of proven methodologies in different contexts, ensuring operational continuity and simplifying integration between internal teams, external suppliers, and clients.

Added value in public and private procurement

More and more tenders require compliance with the ISO 19650 standard as a quality requirement for the information process. This ensures predictability, transparency, and verifiability of the transmitted data.

Alignment with the digital transformation of the construction sector

Digitalization is not only about 3D modeling but also about data management. International standards guide the sector towards uniform digital maturity, essential for integrating technologies such as digital twin, IoT, and advanced collaborative platforms.

ISO 19650 Standard

Relationship between BIM Standards and Information Quality

Clear Information Requirements (EIR/OIR/AIR)

Thanks to the standards, clients can precisely express what information is needed, what it is for, and at what point in the process it should be produced.

Data Structuring and Classification

Standardization makes information readable and manipulable by different software, platforms, and disciplines. This allows for automatic validations, reliable extractions, and consistent content management.

Verification and Approval Processes (CDE and Controlled Workflows)

The use of a Common Data Environment compliant with the standards ensures traceability, versioning, auditability, and lifecycle control of documents and models.

Reduction of Errors and Inconsistencies

A standardized approach avoids discrepancies between the models of various disciplines, improves alignment between design dimensions (3D, 4D, 5D, 6D), and significantly reduces the risks of clashes and variations.

Information Quality as the Foundation of the Digital Twin

A reliable digital twin entirely depends on the quality and consistency of the BIM data. Without standards, the digital twin would lose value and operational reliability.

Quality Assurance, Consistency, and Data Traceability

The standards establish clear rules for the production, verification, approval, and delivery of informational content, ensuring reliability throughout the lifecycle of the project.

Support for Collaboration and Interdisciplinary Coordination

By defining roles, responsibilities, and document flows, they facilitate integrated work among architects, engineers, contractors, suppliers, and managers.

Supporting Long-term Asset Management

It is not limited to the design or construction phase: ISO 19650 considers the entire lifecycle, laying solid foundations for maintenance, asset management, and digital twin.

The ISO 19650 Standard: Structure and Meaning

The significance of ISO 19650 lies in its ability to standardize the information process, avoiding improprieties, customizations, and inconsistent methodologies between clients and operators. It does not impose specific tools or technologies but provides a solid and universally shared framework that establishes how BIM data should be managed to be reliable, consistent, and truly useful.

Origins of ISO 19650: BS 1192 and PAS 1192

ISO 19650 did not emerge from nothing. It is the natural evolution of the British standards BS 1192 and the PAS 1192 series, which first defined a structured method for collaborative information management in BIM projects.

BS 1192:2007

It introduced fundamental concepts such as centralized document management, the structure of the Common Data Environment (CDE), controlled versioning, and rules for file naming. It was the first true reference for digital collaboration in the construction sector.

PAS 1192-2:2013 and PAS 1192-3:2014

These standards expanded the methodology, distinguishing information management during the design/construction phase (PAS 1192-2) from that related to the asset management and facility management phase (PAS 1192-3).
In these specifications, the logic of managing the information lifecycle clearly emerges, which is now central to ISO 19650.

The parts of the ISO 19650 series

ISO 19650, “Organization and digitization of information about buildings and civil engineering works, including building information modelling (BIM) — Information management using building information modelling”, consists of six parts, not all of which have been published yet:

ISO 19650-1 – Concepts and principles

In the ISO 19650-1 – Part 1, the following are introduced:

the fundamental principles of information management based on the life cycle of the work;
the concept of a Common Data Environment (CDE) and its logic for control, review, and approval;
the definition of roles and responsibilities (lead appointed party, task team, appointing party, etc.);
the structure of the information requirements (OIR, AIR, PIR, EIR) and their relationship with decision-making processes.

This part does not provide operational procedures but establishes the conceptual foundations that guide all other sections of the ISO 19650 series. It is the reference framework for understanding how the information process should be organized at a general level.

ISO 19650-2 – Asset delivery phase

The ISO 19650-2 – Part 2 is the most widely used part in design and construction, as it regulates the management of information during the delivery phase of the work.

It establishes:

the process for the preparation, evaluation, and response to Exchange Information Requirements (EIR);
the contents of the main informational documents: pre-contract BEP, post-contract BEP, MIDP, TIDP;
the flow of production, coordination, verification, and delivery of models and documents in the CDE;
the procedures for revisions, approvals, and final delivery of informational content.

The goal is to ensure that every piece of information produced during design and construction is consistent, traceable, and aligned with the client’s requirements.

ISO 19650-3 – Operational phase of assets

The ISO 19650-3 – Part 3 addresses information management in the operational phase of the asset, that is, everything that happens after the delivery of the work.

This part focuses on:

organization and updating of the information necessary for facility management and asset management;
linking the Asset Information Requirements (AIR) to the operational activities of the organization;
managing the informational model as a digital knowledge base to support maintenance, safety, energy management, performance, and asset enhancement;
processes for updating, controlling, and archiving information in the long term.

It is essential to ensure that the informational heritage created during design and construction is truly useful in the daily management of the work.

ISO 19650-4 – Information exchange (in development)

The ISO 19650-4 – Part 4 (currently in development) aims to define the technical and procedural rules for the exchange of information between parties.

It should delve into:

formats, structures, and methods of digital data delivery;
processes for automatic validation and quality controls;
technical requirements to improve interoperability and uniformity in deliveries;
criteria for secure and reliable exchange within the CDE.

This part will complete the operational framework already initiated in the previous sections, focusing on the more technical aspects of data transmission.

ISO 19650-5 – Information security management

The ISO 19650-5 – Part 5 introduces a specific level of depth on information security, particularly relevant in complex or high-risk projects (critical infrastructure, strategic buildings, public works).

It establishes:

principles and measures for protecting data and the model from risks of disclosure, loss, or unauthorized access;
threat assessment strategies and risk management;
organizational and operational measures to ensure a “secure-by-design” approach in data management;
requirements for creating the Information Security Management Plan (ISMP).

It is the part that integrates aspects of cybersecurity within the BIM information process, making the flow of data secure and controllable.

ISO 19650-6 – Health and safety (in development)

The ISO 19650-6 – Part 6, also in development, aims to connect the BIM information process with health and safety aspects on construction sites.

The goal is to establish:

how BIM can support the identification of risks and the planning of preventive measures;
what information needs to be managed to ensure safety in the workplace during design, construction, and management;
roles, responsibilities, and coordination methods;
specific informational requirements for managing safety at every stage of the work.

When completed, it will represent another step towards a fully integrated use of BIM in safety protection processes.

ISO 19650 SERIES

How to Develop a BIM Workflow Compliant with ISO 19650

Correctly applying ISO 19650 requires defining a structured workflow that involves all stakeholders of the project and ensures management, quality, and traceability of information throughout the entire lifecycle of the work. This workflow is based on clear phases, reference documents, and the use of the Common Data Environment (CDE).

Role of the Client

The client plays a strategic role in defining the informational context of the project. Among the main tasks:

define the Exchange Information Requirements (EIR): what information is needed, in what format, with what level of detail, and by what deadlines;
select the project team and establish the responsibilities of the various stakeholders;
ensure resources, tools, and processes necessary for the proper functioning of the information flow;
supervise compliance with ISO 19650 standards, ensuring that all produced data is consistent, complete, and verifiable.

The client thus becomes the central point of reference for the entire informational cycle, ensuring the quality and consistency of the data produced.

Planning the Project Team (MIDP)

The Master Information Delivery Plan (MIDP) is the key document for planning the production of information. It includes:

schedule for the delivery of models and required data;
distribution of roles and responsibilities for each discipline and phase of the project;
linking with the Information Requirements defined by the client (EIR, AIR, OIR);
definition of standards, procedures, and formats to be adhered to for all deliverables.

The MIDP allows for a clear organization of collaboration, avoiding delays and inconsistencies among the various stakeholders.

Information Production and Coordination (TIDP)

The Task Information Delivery Plan (TIDP) translates what is planned in the MIDP into specific operational activities for each team:

identifies what information to produce, by whom, and by when;
establishes the flows for reviewing, approving, and validating data;
includes coordination procedures among multidisciplinary models, ensuring that data is consistent and integrable into the federated model.

The TIDP is essential for transforming planning into operations, allowing for efficient data management throughout the project lifecycle.

Information Sharing and Management in the CDE

The Common Data Environment (CDE) is the heart of BIM collaboration compliant with ISO 19650:

centralizes all models, documents, and data, ensuring a single source of truth;
allows for controlled versioning, traceability, and management of access permissions;
supports real-time collaboration processes, reducing errors and duplications.

The CDE ensures that each stakeholder always accesses up-to-date and consistent information, facilitating communication and coordination.

Verification, Approval, and Archiving

The control and validation phase is crucial to ensure the quality and reliability of the data:

verification of models and documents according to the criteria established by ISO 19650 standard;
formal approval of deliverables before their delivery or publication;
structured archiving of data and models within the CDE, ensuring accessibility and traceability for the entire lifecycle of the work.

This phase closes the information flow, ensuring that the information is certifiable, consultable, and usable even in the future management of assets.

Useful Tools for Working According to BIM ISO Standards

To properly implement ISO 19650 processes, it is essential to have adequate digital tools:

BIM authoring software for multidisciplinary modeling;
CDE platforms for managing, sharing, and archiving data;
coordination and clash detection tools to verify interferences and consistency among models;
document management and approval workflow solutions that integrate automatic quality controls and versioning;
Dashboards and monitoring tools, useful for tracking the status of information production against MIDP/TIDP plans.

FAQ on BIM ISO standards

What are ISO standards?

ISO standards are international technical norms that define rules, guidelines, or requirements to ensure quality, safety, efficiency, and interoperability in processes, products, or services. The main objective is to create a common language on a global scale, allowing organizations from different countries to work with shared and measurable criteria. In the context of BIM, ISO standards serve to regulate not only the technical aspects (formats, data exchange) but also the informational processes (how project data is generated, managed, and shared). This helps to reduce ambiguity, errors, and inefficiencies, increasing the consistency and quality of information throughout the entire lifecycle of the project.

What are BIM ISO Standards and why are they important?

BIM ISO Standards are international norms that define criteria, processes, and requirements for the structured management of information throughout the lifecycle of a project. These standards regulate not only the technical aspects of the informational model but especially the way in which the various stakeholders involved (designers, companies, contracting authorities, managers) produce, organize, exchange, and validate data. Their importance arises from the increasing complexity of projects and the need to operate in increasingly collaborative digital ecosystems. Without shared standards, each party would define its own procedures and formats, making communication difficult and increasing the risks of document inconsistency, duplication, operational errors, and changes during the work. ISO standards applied to BIM (particularly the ISO 19650 series) provide a structured and universally recognized reference capable of ensuring informational consistency, interoperability, and quality of processes, regardless of the national context or the software platform used.

International standards guide the sector towards uniform digital maturity, essential for integrating technologies such as digital twin, IoT, and advanced collaborative platforms.

What is the relationship between BIM Standards and information quality?

Information quality is one of the cornerstones of BIM: a model that is visually appealing but poor, inconsistent, or unverifiable is completely useless from a management perspective. BIM Standards, particularly ISO 19650, define principles and procedures that allow for achieving and maintaining high levels of data quality. Clear informational requirements (EIR/OIR/AIR): thanks to the standards, clients can precisely express what information is needed, what it is for, and when it should be produced during the process; structuring and classification of data: standardization makes information readable and manipulable by different software, platforms, and disciplines, allowing for automatic validations, reliable extractions, and consistent content management; verification and approval processes (CDE and controlled workflows): using a Common Data Environment compliant with the standards ensures traceability, versioning, auditability, and control of the lifecycle of documents and models; reduction of errors and inconsistencies: a standardized approach avoids discrepancies between the models of various disciplines, improves alignment between design dimensions (3D, 4D, 5D, 6D), and significantly reduces the risks of interferences and changes; information quality as the foundation of the digital twin: a reliable digital twin depends entirely on the quality and consistency of the BIM data; guarantees quality, consistency, and traceability of data; supports collaboration and interdisciplinary coordination; supports long-term project management.

What is the structure and meaning of ISO 19650?

The standard is structured into several documents (Part 1, 2, 3, 4, etc.) that cover complementary aspects: general concepts, information management during design and construction phases, information management during operation/maintenance phases, asset information, and, more recently, aspects related to naming, formats, and data exchange. The significance of ISO 19650 lies in its ability to standardize the informational process, avoiding improprieties, customizations, and inconsistent methodologies between clients and operators. It does not impose specific tools or technologies but provides a solid and universally shared framework that establishes how BIM data should be managed to ensure it is reliable, consistent, and truly useful.

What are the origins of ISO 19650?

ISO 19650 did not emerge from scratch. It is the natural evolution of the British standards BS 1192 and the PAS 1192 series, which first defined a structured method for collaborative information management in BIM projects. BS 1192:2007 introduced fundamental concepts such as centralized document management, the structure of the Common Data Environment (CDE), controlled versioning, and rules for file naming. PAS 1192-2:2013 and PAS 1192-3:2014 distinguished information management during the design/construction phase from that related to the management of the asset and facility management. Other PAS 1192 documents (4, 5, 6) explored aspects such as data exchange, information security, and cost management. The British experience, after years of use and practical application, was elevated to international standard, becoming the foundational structure upon which the entire ISO 19650 series is based.

What are the parts of the ISO 19650 series?

ISO 19650 consists of six parts: ISO 19650-1 Concepts and principles, ISO 19650-2 Asset delivery phase, ISO 19650-3 Operational phase of assets, ISO 19650-4 Information exchange (in development), ISO 19650-5 Information security management, ISO 19650-6 Health and safety (in development). Each part defines roles, procedures, document flows, and specific requirements for the lifecycle of BIM information, from design to operational management of the asset.

How to develop a BIM workflow compliant with ISO 19650?

Properly applying ISO 19650 requires defining a structured workflow that involves all project stakeholders and ensures management, quality, and traceability of information throughout the entire lifecycle of the project.
