ISO 15686-4:2014

Overview

ISO 15686-4:2014 - "Building Construction - Service Life Planning - Part 4: Service Life Planning using Building Information Modelling" provides guidance on structuring and exchanging service life planning information using open data standards. The standard focuses on how service life data for buildings, constructed assets and components can be captured, structured and exchanged via Building Information Modelling (BIM) formats to support design, operation, maintenance and whole-life decision-making.

Key topics and technical requirements

• Information exchange framework: Specifies structures for delivering service life information in ways that conform to international exchange standards (notably IFC / ISO 16739) and alternative tabular representations such as COBie.
• Data requirements and property sets: Defines required data for product definition, specification, selection, classification, and occurrences; includes normative property-set templates (Annex A–C) and examples (Annex D).
• Service life metrics: Covers reference service life and estimated service life, required supporting data, context factors (environment, usage), and procedures to express uncertainty.
• Process map and lifecycle flow: Describes information exchanges across lifecycle stages (design, testing, prediction, costing, in-use inspection) and how service life data feed ISO 15686 series processes.
• Interoperability focus: Emphasizes standards-based exchange between BIM and other tools such as Computer Aided Facilities Management (CAFM); excludes proprietary exchange methods and internal application processing.
• Uncertainty and impacts: Guidance on representing uncertainty and recording product impacts (including environmental impact values).

Practical applications

• Enable consistent exchange of service life data between architects, engineers, contractors, facility managers and software systems.
• Support lifecycle costing, maintenance scheduling, durability assessment and whole-life performance evaluation using BIM models.
• Facilitate handover documentation (COBie) and integration of service life data into CAFM and asset-management workflows.
• Help information managers structure national, project or facility-level BIM guidance for durability and service life planning.

Who should use this standard

• Information managers responsible for BIM data frameworks and handover
• Designers and specifiers applying service life data to BIM objects
• Facility managers and CAFM integrators using lifecycle and maintenance data
• Owners, operators and lifecycle-cost analysts involved in whole-life decision making

• COBie (Construction Operations Building Information Exchange)
• Other parts of ISO 15686 series (Parts 1, 2, 3, 5, 7, 8, 9, 10, 11) for prediction, costing, audits and terminology
