Full title and description

STB DIN EN ISO 29481-2 E 2016-08 — Building information models — Information delivery manual — Part 2: Interaction framework. English version (prEN ISO 29481-2:2016 / EN ISO 29481-2:2016) of ISO 29481-2 which specifies a methodology and digital format for describing interactions (coordination acts/transactions) between actors in building asset life-cycle processes to support interoperable exchange of information in BIM workflows.

Abstract

This part of the Information Delivery Manual (IDM) series defines an interaction framework: a methodology, data structures and a schema for describing who does what, when and which information messages are exchanged during coordination tasks across the asset life cycle. It covers interaction maps, transaction/message definitions, templates and schema elements used to make IDM specifications machine-readable and to support software interoperability and repeatable digital workflows in construction and asset management.

General information

• Status: Withdrawn/superseded at international level; originally published as EN ISO 29481-2:2016 (E) — later replaced by ISO 29481-2:2025. National adoptions (e.g., DIN) exist(ed).
• Publication date: ISO original: 2012-12 (ISO 29481-2:2012); European/EN version: 2016-08 (EN ISO 29481-2:2016); German DIN publication (adoption): 2017-09.
• Publisher: ISO (International Organization for Standardization); adopted as EN ISO by CEN and implemented nationally (example: DIN in Germany; STB national designation in some catalogs).
• ICS / categories: 35.240.67 (Building information modelling), 91.010.01 (Construction practice); subject area: BIM / information exchange / interoperability.
• Edition / version: EN ISO 29481-2:2016 (English version dated 2016-08) — originally ISO 29481-2:2012 (Edition 1). Superseded by ISO 29481-2:2025 (Edition 2).
• Number of pages: Varies by language/version: ISO 29481-2:2012 — 74 pages (original); some national/adopted editions (e.g., German DIN/EN PDF) list ca. 94 pages due to front matter and national forewords.

Scope

Specifies a methodology and a formal format for describing an interaction framework for any BIM-related use case across the asset life cycle. The scope includes defining interaction maps (actors, responsibilities, transactions), transaction/message content and sequence, templates and a machine-readable schema to document and execute IDM interaction frameworks. It is intended to support interoperable software implementations, traceable digital communication and repeatable information delivery processes for design, construction, handover and operation.

Key topics and requirements

• Interaction framework concept: structure for describing interactions (actors, roles, responsibilities, triggers).
• Interaction maps and transaction maps: visual and formal representations of coordination flows between participants.
• Message/transaction definitions and templates: what information is exchanged, required content and quality rules.
• Schema and machine-readable format: normative schema for encoding interaction frameworks to enable software interpretation.
• Principles for promotor algorithm and message routing to support automated workflows and responsibility assignment.
• Support for software interoperability and traceability across project phases and asset life-cycle stages.

Typical use and users

Used by BIM/information managers, project managers, contractors, asset owners, digital delivery coordinators, software vendors and systems integrators. Typical applications include defining project-specific IDM documentation, specifying contract-level information exchange requirements, implementing interoperable exchange mechanisms in software, and documenting repeatable coordination processes for design, construction and operations.

FAQ

Q: What is this standard?

A: It is Part 2 of the ISO 29481 Information Delivery Manual series that defines an interaction framework for BIM-related information exchanges — a method and schema to describe who exchanges what information, when and how.

Q: What does it cover?

A: It covers interaction maps, transaction/message definitions, templates and a machine-readable schema to document and execute IDM interaction frameworks that support interoperable, traceable digital communication across project and asset life-cycle phases.

Q: Who typically uses it?

A: BIM managers, information managers, project and contract managers, contractors, asset owners, consultants, software vendors and standards teams — anyone responsible for specifying or implementing structured information exchanges in BIM workflows.

Q: Is it current or superseded?

A: The EN ISO 29481-2:2016 (E) edition reflects the earlier ISO 29481-2:2012 content; at international level the part has been superseded by a later revision (ISO 29481-2:2025). National adoptions based on the 2016/2017 EN/DIN texts remain referenceable but organizations should check for and prefer the 2025 revision for the most up-to-date requirements and schema.

Q: Is it part of a series?

A: Yes — ISO 29481 is a multi-part series (Part 1: Methodology and format; Part 2: Interaction framework; Part 3: related model-view definitions / MVD work). It is also intended to work alongside other BIM and information management standards such as ISO 16739 (IFC) and ISO 19650.

Q: What are the key keywords?

A: BIM, IDM, interaction framework, interaction map, transaction, information delivery, interoperability, IFC, information exchange, ISO 29481.
