ISO 19650 is, at its core, a discipline for answering three questions: what information does the client need, who will produce it, and how will it move between parties without chaos.
The appointing party states what it needs (information requirements). The delivery team responds with how it will deliver (the BIM Execution Plan) and when (the master information delivery plan). The common data environment is where information lives, with clear states: work in progress, shared, published.
Most project problems trace back to skipping the planning step — modelling starts before anyone agrees the level of information need. If you join a project mid-stream, ask for the BEP and the MIDP first; they tell you your actual obligations.
Our BIM Management and ISO 19650 programme walks through drafting these documents against a realistic tender, which is the fastest way to make the standard concrete.
