ISO 19650 Explained for Irish Project Teams

ISO 19650 is the international standard that now governs BIM practice on Irish NDP projects — and yet a significant proportion of Irish architects, engineers and contractors working on those projects cannot confidently explain what it requires beyond "it's the BIM standard." That gap creates real problems: BIM Execution Plans that don't satisfy Employer Information Requirements; Common Data Environments that aren't being used correctly; and LOD deliverables that don't match what the state client expects at each stage gate. This guide explains ISO 19650 for Irish project teams in plain language — the concepts, the key documents, the Irish mandate context, and what compliance actually means in practice.

What Is ISO 19650 and Why Was It Created?

ISO 19650 is the international standard for managing information over the whole life cycle of a built asset using building information modelling. Published by the International Organization for Standardization (ISO), it provides a framework for creating, sharing and managing building information in a structured, consistent and collaborative way across all project participants.

It was created to solve a specific and persistent problem in the construction industry: multiple design teams producing information in incompatible formats, with no consistent structure for sharing, approving and archiving project data. The result — missed coordination issues, rework, variation claims and poor-quality handover — is the most expensive pattern in Irish and international construction. ISO 19650 provides the framework that eliminates this by defining a common information management process that all project parties follow.

ISO 19650-1 vs 19650-2 — The Two Core Parts

ISO 19650 is published in two operationally relevant parts:

• ISO 19650-1 — Concepts and principles. Defines what information management means, the vocabulary (EIR, BEP, CDE, MIDP, LOD, LOIN), and the underlying principles of a managed information environment. This is the conceptual foundation.
• ISO 19650-2 — Delivery phase of assets. Defines the specific process for creating and managing information during design, construction and handover. This is the operational part — what the BEP must contain, how the CDE must be structured, what deliverables must be produced at each stage gate. For Irish project teams, ISO 19650-2 is the document to work from.

The Key Concepts: Information Requirements, BEP, CDE, MIDP

Employer Information Requirements (EIR)

The EIR is the client's statement of what information is needed from the design and construction team — what deliverables, at what LOD, in what format, at what stage gate, and within which CDE platform. On Irish NDP projects, the EIR is issued by the state client (HSE, OGP, DOE, TII) at procurement stage. The design team responds to the EIR in the pre-contract BEP. Understanding what the EIR requires — and confirming that your team can meet it — is the first critical step in Irish NDP BIM compliance.

BIM Execution Plan (BEP)

The BEP is the design team's response to the EIR — the document that describes how the team will manage and deliver the information the client requires. A pre-contract BEP is submitted with the design team's tender; a post-contract BEP is developed after appointment, incorporating project-specific detail. See our dedicated BEP guide for Ireland for the full content requirements.

Common Data Environment (CDE)

The CDE is the single source of truth for all project information — the agreed digital environment (typically a cloud platform such as Autodesk Construction Cloud, Asite or Viewpoint) within which all project data is created, reviewed, approved and shared. ISO 19650 defines four information states that all documents and models pass through in the CDE: Work in Progress → Shared → Published → Archived. See our CDE comparison guide for platform options.

Master Information Delivery Plan (MIDP)

The MIDP is the project-level schedule of all information deliverables — consolidating individual task information delivery plans (TIDPs) from each discipline into a single master schedule showing what will be delivered, by whom, when, and to what LOD. On Irish NDP projects, the MIDP is a live document that is updated at each stage gate and referenced at coordination reviews.

Why ISO 19650 Replaced PAS 1192 for Irish Projects

PAS 1192 (parts 2, 3 and 4) was the UK BIM Level 2 framework that governed BIM practice in Ireland and the UK from approximately 2013 to 2019. ISO 19650 replaced it as the international standard, with broadly equivalent concepts but updated terminology. The AIR becomes the OIR/AIR under ISO 19650; the EIR remains the EIR; the BEP structure is updated; the CDE four-state model formalises what was implied in PAS 1192. Irish projects that previously cited PAS 1192 should now cite ISO 19650:2019 on all documentation.

The Irish NDP Mandate — Who Requires ISO 19650?

What ISO 19650 Compliance Means in Practice for Irish Teams

ISO 19650 compliance on an Irish NDP project means, in practice:

• Producing a pre-contract BEP that responds specifically to the client's EIR before the design team is appointed
• Working within the project's designated CDE platform (not emailing files or using personal cloud storage)
• Producing discipline models at the specified LOD at each RIAI stage gate
• Participating in clash detection and coordination reviews on the project's agreed cycle
• Issuing information through the CDE's formal status workflow — not informally by email
• Maintaining a current MIDP and updating it when programme changes occur

How ASDV Delivers ISO 19650-Aligned BIM for Ireland

ASDV provides BIM support services for Ireland that are structured around ISO 19650 information management practice — working within the project's CDE, to the project's BEP, naming conventions and LOD requirements. We participate in MIDP management, issue models and reports through the CDE on the project issue schedule, and maintain a clash register through coordination reviews. See our BIM services Ireland page for the full scope.
