Building Passport: Checklist Before the Survey Starts
A practical checklist to prepare your building passport without unnecessary delays. What to gather before surveying, what to clarify with the vendor, and where mistakes usually happen.
Building passport projects often start only when something becomes urgent – a renovation, a sale, missing documentation, or communication with authorities. Most delays usually come from one cause: unclear inputs and scope.
Define the purpose first
The first step is to define what the documentation is for. Internal asset records, follow-up design work, and administrative use do not always require the same depth. Without a clear purpose, outputs are often either insufficient or unnecessarily extensive.
Prepare existing materials in advance
Collect whatever already exists: old drawings, previous project documentation, occupancy records, revisions, change history, and photos. Even incomplete materials help teams orient quickly and plan the survey more efficiently.
Check site access early
Before measurement, confirm access to all relevant areas: shared parts, basements, technical rooms, roof spaces, and restricted zones. In practice, inaccessible areas are a common reason for re-visits and timeline extension.
Specify deliverables clearly
Confirm whether you need only core drawings or also supplementary outputs such as area tables, room lists, and BIM deliverables (IFC/RVT). If the result should be used by designers or FM teams, define data expectations at the beginning.
Common sources of delay
Typical issues include late scope changes, partial access during survey, and underestimating differences between historic documentation and the current state. Another frequent problem is assuming an old project can replace current measurement.
A practical workflow
A reliable sequence is simple: define purpose, gather inputs, confirm scope, secure access, perform survey, process outputs, and review before final handover. This usually reduces rework and shortens turnaround.
Summary
A quality building passport does not start in CAD software. It starts with clear preparation and expectations. If scope is uncertain, a short expert consultation is usually more efficient than correcting outputs later.
