How do I score COBie handover readiness?
Bildstak scores COBie handover readiness by checking each asset in the model against the required COBie data fields — type, component, space, system, spare parts — and returning a completion percentage by asset category, cited element by element, so gaps are visible before the handover gate.
COBie (Construction Operations Building Information Exchange) is the structured dataset that hands the completed building to the facilities management team: asset lists, types, spaces, systems, spare parts and warranty information. Getting it right matters because gaps mean the FM team inherits an incomplete asset register on day one.
Bildstak checks COBie readiness across the model:
1. Connect the BIM model — IFC file, Speckle or Autodesk APS. Bildstak reads the element data alongside any COBie exports already produced. 2. Map to COBie worksheets — Bildstak checks the six core worksheets — Type, Component, Space, Floor, System, Spare — against the elements in the model. 3. Score completeness — for each asset category (HVAC equipment, lighting, structural, etc.) Bildstak returns a percentage complete score and a list of elements with missing fields. 4. Identify gaps — ask "which MEP components are missing manufacturer and model number?" or "what percentage of spaces have all required COBie fields?" and get a cited answer. 5. Track progress — rerun the check as the model is updated to track completeness over time toward the handover milestone.
Practical tip: COBie readiness checking should start at Practical Completion minus 4–6 weeks, not on the day of handover. Bildstak is designed to be run continuously so the BIM team can close gaps iteratively.
The COBie check sits alongside IDS validation and clash status in Bildstak's information quality view, giving a single readiness score across all three dimensions.
