ISO 19650 explained: the architect's guide to BIM information management (2026)

ISO 19650 is the international standard for managing BIM information across a built asset’s lifecycle. The series has six parts, published between 2018 and 2025. It names three parties (appointing party, lead appointed party, appointed party), four information requirement documents (OIR, PIR, AIR, EIR), and a BIM execution plan (BEP) that the delivery team writes in response. Information management is a function that the parties assign, not a fourth party.

Key ISO 19650 numbers at a glance

Why does ISO 19650 exist?

ISO 19650 exists to solve a coordination problem that predates digital construction: information produced during design and construction rarely survived handover into building operation. In the UK, the BS 1192 and PAS 1192 series set out the BIM Level 2 approach; BS EN ISO 19650-1 and -2 superseded BS 1192:2007 and PAS 1192-2:2013 when they were published (the ISO parts date from 2018, the UK adoption from early 2019). ISO 19650 governs how information is managed, not what the information contains. IFC describes what data looks like. IDS and MVDs describe what data must be present for a specific exchange. ISO 19650 governs the process between the parties requesting and delivering that data across a project’s life.

What are the six parts of ISO 19650?

ISO 19650 is a six-part series published by ISO and adopted in Europe as EN ISO 19650. Part 1 (2018) sets out concepts and principles. Part 2 (2018) covers the delivery phase of assets. Part 3 (2020) covers the operational phase. Part 4 (2022) covers information exchange. Part 5 (2020) sets out a security-minded approach to information management. Part 6 (2025) covers health and safety information. National bodies publish adopted versions, for example BS EN ISO 19650 in the UK, DIN EN ISO 19650 in Germany, NF EN ISO 19650 in France and UNI EN ISO 19650 in Italy. Prices differ by national body; check the current price with the body that sells the part you need.

What is the difference between a PIM and an AIM?

ISO 19650 distinguishes the project information model (PIM) from the asset information model (AIM). The PIM is the information model developed during the delivery phase: design, procurement, and construction. The AIM supports the management and operation of the asset. At the end of the delivery phase, relevant information from the PIM is used to update or create the AIM; ISO 19650-3 covers the operational phase. Asset information requirements (AIR), set by the appointing party, define what the AIM must contain. The format of any handover data (COBie is one common example) is set by the project’s information requirements, not by ISO 19650 itself.

What documents does the ISO 19650 framework require?

ISO 19650 organises information requirements into a chain. The organisational information requirements (OIR) and project information requirements (PIR) feed the exchange information requirements (EIR), which the appointing party issues to bidders. Asset information requirements (AIR) define what the AIM must contain. In response, each bidder produces a pre-appointment BIM execution plan (BEP) that proposes how it would meet the EIR; after appointment the delivery team confirms its BEP (UK BIM Framework BEP guidance, cdbb.cam.ac.uk). Each task team prepares a task information delivery plan (TIDP), and the lead appointed party collates the TIDPs into the master information delivery plan (MIDP) (same guidance, section 2.6). The MIDP is a delivery plan, separate from the BEP, although the UK BIM Toolkit BEP template references it in an appendix. The level of information need of each deliverable is defined under EN 17412-1.

What happened to the BIM maturity levels?

The BIM Level 0 to Level 3 wedge belongs to the earlier UK programme and to PAS 1192, not to ISO 19650. The April 2016 UK government mandate required BIM Level 2 on centrally procured public projects. When BS EN ISO 19650-1 and -2 replaced BS 1192:2007 and PAS 1192-2:2013, the UK BIM Framework took over as the guidance that carries Level 2 principles forward under the ISO series (UK BIM Framework FAQ). ISO 19650 is a process standard: a project meets the information management requirements its appointing party sets in the EIR and the appointment documents, not a numbered level. For how ISO 19650-1 describes maturity, read the standard itself.

What parties and functions does ISO 19650 define for the design team?

ISO 19650 uses abstract names, not professional titles, because the same firm can occupy different positions on different appointments. It names three parties. The appointing party is the client, asset owner, or project sponsor, and issues the EIR. The lead appointed party is the party that leads a delivery team and is responsible for information delivery on that appointment; this is often the architect on design-led work, but not by rule. Appointed parties deliver their task information to the lead appointed party. Task teams sit inside delivery teams.

Information management is a function, not a party and not a job title. ISO 19650-2 lists the information management activities (Annex A); the delivery team’s BEP records who performs each (BEP guidance, Table 1.1, “Information management function schedule”). ISO 19650 does not prescribe which profession fills which role. A structural engineer can be the lead appointed party on a structure-led project. An architect can lead a design-led appointment and be an appointed party on an M&E-led appointment running in parallel.

Where is ISO 19650 used?

ISO 19650 is a voluntary standard. Whether a client requires it depends on the jurisdiction and the appointment. In the UK, the UK BIM Framework guides use of the BS EN ISO 19650 series, and clients can cite it in their EIRs. Several countries publish national versions or annexes, so practitioners on cross-border projects need the national overlay that each jurisdiction adds on top of the ISO baseline.

What are the most common mistakes architects make with ISO 19650?

Four ISO 19650 errors recur across projects.

1. Treating the EIR as a form, not a specification. The EIR is part of the appointment documents. Teams that file it without periodic review miss updates to file naming, software commitments, and delivery milestones.

2. Conflating PIM and AIM deliverables. The PIM serves the delivery phase. The AIM serves operation. Architects who populate parameters for coordination only, without addressing the AIR, produce a PIM that cannot feed the AIM.

3. Assuming the architect is the lead appointed party. The lead role follows the appointment, not the profession. Confirm the party structure at EIR stage, not when the TIDP is due.

4. Skipping ISO 19650-5 where sensitive information is involved. Part 5 applies wherever sensitive asset information creates security risks. Where an EIR references Part 5, the BEP response needs to address it.

Frequently asked questions

What is ISO 19650 and why does it matter for architects?

ISO 19650 is the international standard for managing information across a built asset’s lifecycle using BIM. It matters to architects because clients cite it in their EIRs, and the architect’s BEP and delivery plans respond to that EIR. ISO 19650-1 sets out concepts and principles; ISO 19650-2 covers the delivery phase.

What is the difference between an EIR and a BEP under ISO 19650-2?

The exchange information requirements (EIR) are the appointing party’s specification of what information is needed and when. The BIM execution plan (BEP) is the delivery team’s response, led by the lead appointed party, confirming how the team will meet those requirements. The TIDPs and MIDP are separate delivery plans; the MIDP is collated from the TIDPs.

Which parts of ISO 19650 should an architect read first?

Parts 1 and 2 cover most design-phase needs: Part 1 sets concepts and principles, Part 2 covers the delivery phase including the move from EIR to BEP. Part 5 matters where an EIR asks for a security-minded approach. Parts 3, 4, and 6 cover the operational phase, information exchange, and health and safety information respectively.

Where is ISO 19650 mandatory for architectural projects?

ISO 19650 is a voluntary standard; its requirements apply on a project when the appointment documents call for it. UK clients can do so, following the 2016 Level 2 mandate and the move to the ISO series. For other countries, check the national BIM mandate and the project EIR.
