Here's the strange economics of BIM today: an enormous amount of money is spent
producing detailed building information models during design and construction —
and the moment the building is handed over, the models go into a folder named
something like Slutleverans_FINAL_v2 and are never opened again.
The construction project lasted three years. The owner will hold the building for fifty. Guess who got the models built for their needs?
The handover gap
Construction BIM answers construction questions: clash detection, quantities, sequencing. Owners have different questions:
- Which apartments are affected if we replace this riser?
- What's the total rentable area on floor 3, per the latest layout?
- Where exactly is the fire cell boundary this door penetrates?
- What did we install in 2019, and who services it?
The data to answer most of these exists in the handover models. It's just locked behind desktop software that costs a monthly salary per seat and assumes you know what an IFC property set is.
Owners don't need authoring tools
This is the core misunderstanding. Property owners are told that "doing BIM" means buying the same tools the architects use. It doesn't. Owners rarely need to author models — they need to read, query and annotate them:
- Open a model in the browser, no install, no training day.
- Find the thing (a door, a duct, a room) and read its properties.
- Share a link to that exact view with a contractor.
- Keep the model current through renovations — which mostly means demanding updated models in every contract, a paperwork fix, not a technology one.
That reading-and-querying layer is what we built bimma.app for. And for the strategy side — what to demand in contracts, how to structure requirements, what to do with twenty years of mixed-quality drawings — our sister company bimma.se consults for owners specifically.
Start smaller than you think
You don't need a "digital twin initiative". You need your existing models out of the archive folder and in front of the people running the building. In our experience the first useful result — a facilities manager answering their own question without calling a consultant — arrives in the first week.
The fifty-year phase of a building deserves at least as good data as the three-year phase got. We can help.
