Your digital BIM guide: practical ISO 19650 help for projects that don't have a department for it
Information management that works on small projects too
Information management that works on small projects too
Good information management means knowing what you need from your project, asking for it clearly, and getting it in a form you can actually use. That applies to a house extension just as much as to a hospital — there are simply fewer things to ask for. Guide Digital helps clients define what they need, and helps architects, engineers and contractors deliver it, using the ISO 19650 process.

Information management has its own vocabulary, set out in ISO 19650. The terms are worth learning rather than avoiding — your design team will recognise them, and using them correctly is what makes your requirements enforceable.
The vocabulary is changing, but nothing is settled. Draft revisions to ISO 19650 went out for public consultation on 10 March 2026. That consultation closed in June, and in August the committee called for a further round of drafting rather than moving to publication. In the drafts, the EIR becomes Information Production Requirements, the BIM Execution Plan becomes an Information Production Plan, and the MIDP and TIDP merge into a single Information Production Schedule. OIR, AIR and PIR stop being fixed document types and become perspectives that are collated and filtered for each appointment. The current editions remain in force, so both sets of terms are shown here, and our tools produce documents labelled for both.
OIR, AIR and PIR — your information requirements What you need to know: to run your organisation, to operate the finished building, and to make decisions during the project. Three separate documents today. The draft revision keeps the ideas but stops treating them as fixed document types, asking instead which of them a particular appointment actually needs.
Information Production Requirements — currently the EIR What you're asking the design and construction team to produce, in what format, and by when. This is the document the free generator below creates, labelled for both current and proposed terminology.
BEP — BIM Execution Plan The team's answer to your requirements — how they intend to meet them. Submitted with their tender, then confirmed after appointment. In the draft revision it becomes the Information Production Plan.
Golden thread — Building Safety Act duty For higher-risk buildings — at least 18 metres or 7 storeys, with two or more residential units — a digital, structured, secure record of safety information maintained across the building's life. Hospitals and care homes of that height also count during design and construction. A legal duty, not best practice.
