Project Lifecycle-Based BIM Information Delivery and Responsibility Model - An Integrated Matrix Linking Information Requirements, Deliverables, Stakeholder Responsibilities, and Project Milestones

This research working paper presents the Project Lifecycle-Based BIM Information Delivery and Responsibility Model, a configurable conceptual and applied framework that integrates information requirements, deliverables, stakeholder responsibilities, information maturity, and project milestones across the project and asset lifecycle. The research addresses a persistent implementation gap in BIM-based information management: information requirements, delivery plans, model maturity, contractual responsibilities, Common Data Environment workflows, and asset-information transitions are frequently managed through separate documents and processes without a unified lifecycle view. The proposed model connects why information is required, what must be delivered, when it must be submitted and accepted, who is responsible and accountable, and how the information remains usable throughout subsequent lifecycle stages. The model covers eight stages, extending from Pre-Concept and Concept Design through Detailed Design, Construction, Handover, Operation and Maintenance, and Decommissioning or Repurposing. It integrates Organizational Information Requirements (OIR), Asset Information Requirements (AIR), Project Information Requirements (PIR), and Exchange Information Requirements (EIR) with Level of Information Need, indicative model maturity, BIM uses, information-delivery milestones, acceptance controls, and the progressive transition from the Project Information Model (PIM) to the Asset Information Model (AIM). The principal research outputs include a lifecycle integration matrix, complete information-requirement and input-output matrices, stage-level and deliverable-level RACI matrices, an information-delivery and acceptance schedule, a PIM-to-AIM transition matrix, and a catalogue of forty-one information deliverables classified into Basic, Recommended, and Advanced implementation levels. The study follows a design-science-oriented conceptual research approach informed by international standards and established BIM, information-management, and asset-management literature, including the principles addressed by the ISO 19650 series. Its conceptual synthesis and design choices are additionally informed by the author’s progressive professional experience across BIM modelling, coordination, management, development, professional education, and enterprise solution architecture. This experience is used as a practitioner-informed design basis rather than as systematically collected empirical evidence. The lifecycle stages, classifications, RACI assignments, implementation rules, and indicative maturity references are author-developed and configurable provisions. They should not be interpreted as universal ISO 19650 requirements or as substitutes for applicable standards, appointments, contracts, regulations, procurement strategies, or project-specific governance arrangements. The working paper establishes a structured foundation for scholarly review, professional application, and future empirical validation. It is intended to support appointing parties, lead appointed parties, BIM and information managers, consultants, contractors, asset operators, and researchers seeking a traceable lifecycle-oriented approach to BIM information delivery and responsibility management. Future research will evaluate the model through independent expert review, Delphi-based refinement, comparative project case studies, inter-rater assessment, and Asset Information Model usability evaluation.
