BIM4HOUSING OPERATIONS WORKING GROUP MEETING 01-10-2026
Date: 1 October 2026
Duration: 1h 39m 1s
- Meeting Focus
The meeting centred on the persistent gap between the information expected at handover and what is actually delivered to building owners and operational teams, with particular focus on as-built information, Regulation 38, BIM models, contracts, responsibility and client awareness.
- As-Built Information and Operational Use
- Participants agreed that as-built drawings and detailed M&E information are essential for maintenance and future works, but are frequently not trusted, incomplete or not produced at all.
- The lack of reliable information forces organisations to re-survey buildings, increasing cost and risk.
- 360° photography was discussed as a potential practical method of recording what is actually constructed, although the overriding requirement is that the information handed over must be accurate.
- Maintenance teams particularly require wiring diagrams, P&IDs, system layouts and other detailed graphical information to locate, understand and repair assets. 01-10-2026-Transcript-BIM4Housi…
- A key proposal was to distinguish between design/final-construction information and genuinely verified information; however, concerns were raised that simply labelling information “unverified” does not adequately manage the safety risk.
- Handover, Quality and Responsibility
- Real-world examples demonstrated that buildings are sometimes handed over with missing drawings, unresolved defects and inadequate fire-safety information. 01-10-2026-Transcript-BIM4Housi…
- Participants highlighted the importance of site verification, ownership and clear responsibility rather than relying solely on paperwork or contractual sign-off.
- Client awareness was identified as a major issue: clients may not know what information they should request, allowing inadequate information to be accepted. 01-10-2026-Transcript-BIM4Housi…
- The group discussed the need for better examples of good contractual requirements and good practice that organisations can adopt.
- BIM, Golden Thread and Regulation 38
- The meeting challenged the assumption that a BIM model automatically represents the completed building. Most models remain primarily design models, and installation contractors are not necessarily required or paid to update them with what was actually installed. 01-10-2026-Transcript-BIM4Housi…
- If fully updated BIM models are required, this needs to be explicitly specified and funded.
- Base-build and fit-out contracts can create disconnected information, potentially leaving the overall building record incomplete.
- Regulation 38 was discussed as an important handover and risk-management issue, with concern that even clients and industry professionals may not fully understand its application.
- Culture, Commercial Pressure and Industry Change
- A recurring theme was the conflict between commercial pressure to complete projects and the need to challenge inadequate information or workmanship.
- Participants emphasised that individuals need sufficient authority to resist poor handovers without fearing loss of business.
- The group identified ownership, responsibility, standardisation and clear contractual clauses as fundamental changes needed to prevent the same problems recurring. 01-10-2026-Transcript-BIM4Housi…
- Integrated Project Delivery (IPD) was mentioned as one contractual approach that could help establish clearer responsibilities.
- Next Steps and Wider Engagement
- The group proposed further work on contracts, client guidance and as-built information, including signposting participants to the As-Built “How” Working Group beginning 21 October. 01-10-2026-Transcript-BIM4Housi…
- There was interest in developing clearer guidance for different types of clients, owners and Accountable Persons.
- Potential engagement with regulators and organisations involved in PFI/PPP handback was discussed.
- AI was considered as a possible future tool for validating submitted building information, although participants noted that fragmented standards, regulations and knowledge make reliable AI validation difficult at present. 01-10-2026-Transcript-BIM4Housi…
Key Takeaways
- Accurate, verified as-built information is essential to safe and effective building operation.
- BIM should not be assumed to represent the completed asset unless this is explicitly required, funded and verified.
- Ownership and responsibility at handover must be clearly defined.
- Stronger contracts, client education and standardisation are needed.
- Technology such as 360° capture and AI can support the process, but better data, clear requirements and human accountability must come first.
